Chapter V: LIMA. V. fusiformis, sulcis transversis, striisque

longitudinalibus.

Rumph. Mus. t. 28. f. T.

Testa fusiformis, scabriuscula, striis longitudinalibus secundum testam, et sulcis secundum anfractus adscendentibus margine acutiusculis. Color albidus sulcis elevatis rubris--albidus sulcis elevatis flavis albo interruptis. Spira longitudine ventris. Apertura oblonga, intus alba. Basis acuta, emarginata. Labium exterius integrum; interius nullum. Columella dentibus 4 obliqius.

These features fairly enough suit the _Mitra filosa_, generally, and with reason, supposed to be the _V. filaris_ of the 'Mantissa.' The cited figure however, seems _M. gracilis_ of Reeve.

BUCCINUM.

The species which compose this group in the 'Museum' were originally separated under many generic designations.

1. BUCCINUM. Testa ovata, ventricosa. Apertura integra, semilunaris, superne extrorsum, postice introrsum.

2. CASSIDA. Testa ovata, gibba. Cauda reflexa oblique. Apertura longitudinalis, obliqua.

3. LYRA. Testa ovata, ventricosa. Apertura ovata, patens, pone submarginata. Labium interius nullum. Columella compressa, nitida.

4. TURRICULA. (No definition: evidently intended for all the turreted shells.)

5. MORION. Testa oblonga, inermis. Apertura oblonga, labio interiore reflexo unidentato.

In the first were located the _Dolia_, and _B. echinophorum_; in the second the _Cassides_, with _B. papillosum_ and _arcularia_; in the third the _Harpæ_ and _Purpuræ_; in the fourth the _Terebræ_; in the fifth _B. glans_, _spiratum_, _glabratum_.

_B. undosum_ was located in _Murex_.

B. PERDIX. _B._ umbilicatum subsulcatum, basi recta.

The proposed name was _B. pennatum_, adopted from Rumphius: "lunari-patula" was not in the manuscript.

B. POMUM. _B._ exumbilicatum, labio utroque dentato.

"Barr. Ic. t. 1325. f. 12" (cited in the 'Systema'), and "Klein, 95. Semicassis, striata, costosa", were the additional synonyms of the manuscript: "s. sulcata", "nullum, interne", "at vero in adultioribus accrescit planum album", were subsequent emendations.

B. DOLIUM. _B._ emarginatum subsulcatum rugosum, labio exteriore reflexo dentato.

The _Dolium fimbriatum_, or, as Deshayes prefers it, _D. Minjac_ (the Malay name was Bia Minjac in Rumphius, who preceded Adanson), was assuredly the shell described in the 'Museum', as the recorded dentation of the outer lip clearly manifests. An excellent figure of it in Petiver ("Gaz. t. 99. f. 11") was cited in the original copy, where the drawing of Gualtieri was not referred to.

B. ECHINOPHORUM. _B._ (changed to _Cassida_) tuberibus ("quaterna serie" interpolated) nodosum.

The reference to Rumphius was correctly written 1, not I, in the original, where "albido-flavescens" was the indicated colouring. The printed emendations were "quadruplici s. quintuplici", instead of "triplici", and the entire account of the aperture, which at first ran simply as follows, "Labium exterius crassius, margine tenuiore, interne subrugosum, obsolete dentatum."

B. TUBEROSUM. _B._ tuberibus gemina serie nodosum.

The entire published account of this species had been interpolated by Linnæus in the written copy, with the exception of the "color pallidus." The "nodis anterioribus" was a misprint for "nodis acutioribus."

Gualtieri's admirable figure of the _Cassis tuberosa_ of authors was not, however, cited, which confirms my statement that the species of the 'Museum' was not the _Cassis_ usually so designated.

B. CORNUTUM. _Cas._ acuminibus antice cingentibus, superficic reticulata.

The I in the reference to Rumphius was a misprint for the written 1: "maculata" was originally "maculis griseis."

B. RUFUM. _Cas._ nodis sparsis.

"Pyri" was a misprint for the written "pugni". Neither the "maculis fuscis" nor the "Variat tota albo colore" were originally present. The Rumphian name _rubra_ was the one written.

B. FLAMMEUM. _Cas._ longitudinaliter striata, antice subnodosa.

To the solitary synonym our author had added "List. t. 1004. f. 69" and "Sloan. Hist. 2. p. 242. n. 2". The final remark was not in the copy.

B. TESTICULUS. _Cas._ lævis, striis longitudinalibus, sulcis transversalibus.

"Vix ullus" was at first "nullus": "læve" was not present.

B. DECUSSATUM. _Cas._ lævis, striis decussatis, labio exteriore dentato.

"Bonan. Clas. 3. t. 157" was an additional synonym.

B. AREOLA. _Cas._ glabra, spira papillosa.

The erroneous references to Gualtieri, and to the figure 2 of Rumphius, were not present in the original, nor was there any allusion made to the sculpture of the inner lip.

B. ERINACEUS. _Cas._ subsulcata, antice nodosa, labio edentulo, postice extrorsum denticulato.

The entire account of this _Cassis_ was interpolated by Linnæus in the pages of his amanuensis.

B. GLAUCUM. _Cas._ glabra, antice muricata, labio dentato, postice extrorsum denticulato.

The superfluous A in the reference to Gualtieri was a misprint: "inferne" was "interne": the "acuminata" and "marginatum" were emendations.

B. VIBEX. _Cas._ glabra, labio edentulo, postice extrorsum denticulato.

The figures 8 and 9 of Rumphius were not cited.

B. PAPILLOSUM. _Cas._ papillis decussatis, labio tenui, extus denticulato, fauce glabra.

"Rectum" followed "exterius" in the written copy, wherein "s. albidus" and "antice sinu excavata" were not to be found.

B. GLANS. _Morion_ labio exteriore denticulato, interiore bidentato.

"Labium exterius margine postico denticulato" was omitted in printing.

B. ARCULARIA. _Cas._ longitudinaliter sulcata, labio exteriore tenui, interiore maximo.

B. COSTATUM. _Lyra_ costis longitudinalibus, antice prominulis, alternis obsoletis.

This diagnosis but ill suits the _Many-ridged Harp_, which, of late, has been considered identical.

B. HARPA. _Lyra_ costis longitudinalibus antice mucronatis.

The shell is described in the MS. as "striata subtilissime longitudinaliter", and "Pet. Amb. t. 2. f. 2", "Pet. Gaz. t. 48. f. 13" (the latter quoted also in the 'Systema') are there substituted for the reference to Gualtieri. The printed additions are considerable; to wit, "costæ vero striis transversis", "anfractibus costis mucronatis", "denticulatum."

B. PERSICUM. _Lyra_ læviuscula, labii margine crenulato.

The erroneous citation of Grew (t. 9. f. 5, 6) in the 'Systema' had been adopted in the manuscript.

B. PATULUM. _Lyra_ muricata spinis obtusis.

Neither the erroneous reference to Gualtieri, plate 51. f. A (which was designed for _Purpura hæmastoma_), nor the "color interne rufescens", is to be found in the manuscript.

B. SMARAGDULUS. _Lyra_ glaberrima, columella denticulata.

Neither the erroneous reference to d'Argenville, nor the specific name derived from his figure, is to be found in the MS. The proposed appellation was _L. vitrea_. "Simillima Cassid, lapillo, sed glabra, et columella crenata" is the unprinted remark.

B. SPIRATUM. _Morion_ umbilicatus, anfractibus distinctis canaliculo.

The specified colouring was "alba, maculis longitudinalibus fuscis"; "pone bifidum" followed "integrum." The intended name was _M. canaliculatus_.

B. GLABRATUM. _Morion_ umbilico descendente flexuoso.

d'Arg. Conch t. 12. f. G.

"Testa oblonga, acuminata, obtusiuscula, glaberrima, anfractibus confluentibus, Neritarum maximarum pondere. Color albo-flavescens, nitidus. Apertura obliqua, profunde emarginata. Labium exterius integerrimum. Labium interius antice reflexum adnatum, dein solutum brevius flexuosum, descendens ad basin. Sulcus profundus distinguit basin testæ. Umbilicus pone labium interius descendens ad basin sulco".

B. VIRGINEUM. I can find no account of this shell in the written copy.

B. UNDOSUM. The nearest approach to this species seems the variety B. of the _Murex succinctus_ (the shell so named in the 'Mantissa').

_M._ lævis, sulcis transversis lævibus, angulo marginali.

d'Arg. Conch. t. 12. f. N. Bon. 3. f. 47.

Testa ovata, absque tuberculis magnitudine nucis, exarata sulcis transversis pallidis, eminentibus vero lineis luteis. Spira obtusa, anfractibus rotundatis. Cauda teretiuscula. Apertura ovata, margine crasso, nec alia costa laterali crassa.

Var. B. Rugis s. angulis obliteratis 5 longitudinalibus.

B. MACULATUM. _Turricula_ elongata, anfractibus lævibus integerrimis.

The l. of Gualtieri, and the reference to d'Argenville, were printed emendations.

B. CRENULATUM. _Turric._ elongata, anfractibus margine crenatis.

The reference to Gualtieri was an emendation.

B. STRIGILATUM. _Turric._ elongata, oblique striata.

B. DUPLICATUM. _Turric._ elongata emarginata, anfractibus bipartitis striatis.

STROMBUS.

This genus, rendered more natural by the omission of _S. lividus_ and _ater_ (assigned to _Turricula_), appeared under the designation of HARPAGO with the following definition:--

Testa depressa, nodosa. Apertura longitudinalis. Labium antice dilatatum ultra basin.

The _Strombi_ of the manuscript were the young of this genus (erased by Linnæus) and certain Lamarckian _Fusi_, _Pyrulæ_, and _Fasciolariæ_.

S. CHIRAGRA. _Har._ labii spinis lævibus 6, extimis recurvis, fauce striata.

"Bar. Icon. 327. f. 1." was an additional synonym.

S. SCORPIUS. _Har._ labii spinis nodosis _7_, fauce striata.

The published account was enlarged by the following passages, which are not to be found in the written copy: "crenulato cincta", "lato, brevi", "s. incarnata", "s. testaceo-nebulosus". "Distinctum" was originally "obscuro", and "repandus, inflexus" was "denticulatus."

S. LAMBIS. _Har._ labii spinis lævibus _7_, fauce lævi.

"Bar. Icon. t. 1326. f. _7_" was the synonym omitted in printing. The name was borrowed from d'Argenville.

S. MILLEPEDA. _Har._ labii spinis lævibus 10.

"Anteriora" was "posteriora" in the manuscript.

S. LENTIGINOSUS. _Har._ labio inermi integro rotundato, angulis pluribus nodosis.

The "aut marginatum" was "fragile, diaphanum", so that a young shell appears to have furnished the materials for description.

S. GALLUS. _Har._ labio inermi mucronato, cingulo dorsali spinoso.

S. AURIS-DIANÆ. _Har._ labio inermi muricato, cauda recurva, lobo incurvato.

The "32. f. II." was a misprint for the written "17. f. O." The printed additions are "usque" and "Color testaceo et albido nebulosus."

S. PUGILIS. _Har._ labio inermi obtuso, spira spinosa distincta, basi emarginata.

"Nitida", and "sed spira albida", were not found in the original.

S. LUHUANUS. _Har._ labio obtuso, antice posticeque emarginata.

Few of the details were present in the original copy, but appear to have been added, to discriminate the species from the allied _gibberulus_. "Spira obtusa brevis" was added by the hand of Linnæus; "sæpe subplicati", "postice lobo obsoleto instructum", "intus", "Columella nigricans", "Cauda nulla, sed postice emarginata", were all absent from the MS.

S. GIBBERULUS. _Har._ labio inermi dorso lævi, spira repanda.

The printed additions are "subtus planiuscula", "læves", "fuscum", and the final remark.

S. LATISSIMUS. _Har._ labio inermi rotundato, spira subnodosa breviore, dorso lævi.

S. EPIDROMIS. _Har._ labio inermi dilatato, dorso lævi, spira subnodosa.

The _S. epidromis_, as it originally stood in the manuscript, was a recognizable species, and precisely identical with the shell so named in the 'Systema'; for the erroneous reference to Gualtieri was not present, neither was "carinato," nor any of the discordant details from "interius" to the termination. As the printed description now stands, it would suit _S. emarginatus_ or _succinctus_, at the least, equally well. I doubt not our author, when correcting the press, forgot his own species, and added the partial essentials of one species to those of another.

S. CANARIUM. _Har._ labio inermi dilatato, dorso spiraque lævibus.

The erroneous reference to plate 37 of Rumphius was not present in the written copy, which contains the additional synonyms of "Pet. Gaz. t. 98. f. 11", and "Klein, t. 4. f. 73": the latter was not there originally. The early description has been improved, in the press, by the addition of "obovata", "Faux lævis, alba", and "longitudinaliter subundulatus."

S. VITTATUS. _Har._ labiis inermibus, spiræ anfractibus vitta interstinctis.

S. URCEUS. _Har._ labiis inermibus striatis, dorso nodoso.

The erroneous reference to Gualtieri was not present in the original, but in place of it the 37. W. of Rumphius (_S. mutabilis_): "Spira testa brevior, plicato-subnodosa" was, likewise, absent. "Klein, 49, urceus fimbriatus" (a name for Rumph. t. 37. f. F & W) was interpolated by our author.

S. ATER. _Turricula_ labiata.

Neither the reference to Rumphius, nor the "et postice emarginatum" were found in the original. This confirms my expressed belief that the Museum species (to which no name was at first attached) was distinct from that of the 'Systema.'

S. LIVIDUS. _Turric._ labiata, anfractibus serie subspinosa.

This was located in a section of _Turricula_ distinguished as having the outer lip dilated and rounded.

* * * * *

Besides the above, the following unprinted details were found in the manuscript:--

The _Strombus gigas_ was described at length under the appellation of _Harpago gigas_.

_Har._ labio inermi rotundato, dorso spiraque subulato-spinosis.

Gualt. t. 34. f. A. Bar. Icon. 1727. f. 7.

Testa gibba, maxima, magnitudine capitis. Cauda obtusa. Spira spinis patentibus, subulatis, validis. Anfractus desinens in dorso spina. Series in dorso spinarum maximarum ferme conicarum. Labium dilatatum, rotundatum, spira longius, vix adnatum spiræ. Faux glabra, nitida, incarnata. Color pallidus.

The _Strombus dentatus?_ was also defined (without a specific appellation) by the following characters:--

_Har._ labio dentato, testa lævis, plicato-nodosa.

Testa simillima reliquis, longitudine articuli digiti, lævis, flavescens, subplicata, plicis antice acuminatis nodis. Spira acutiuscula, similiter plicata, nodosa. Labium exterius minus dilatatum, postice margine dentatum et interne fuscum, striatum. Labium internum crassum, integrum, læve.

The _Strombus palustris_, although not published until the twelfth edition of the 'Systema,' had been already defined in the 'Museum' as _Turricula cornea_.

_Tur._ decussatim rugosa, labio dilatato.

Rumph. 101. t. 30. f. Q. Strombus palustris.

Testa crassa, rudis, pyramidalis, cornea aut plumbea, anfractibus 12 et ultra, secundum spiras transversim aliquot striis exarata, longitudinaliter subplicata, adcoque sine spinis rugosissima. Labium dilatatum, rotundatum, concavum, edentulum.

MUREX.

The definition of this genus ran as follows:--

Testa subovata, spinosa. Apertura coarctata, ovata, desinens in canalem tubuloso-conniventem.

This was evidently designed for the _Murices_ proper. The other species of the 'Museum' were distributed in the groups of _Cassis_, _Turricula_, _Bulla_, and _Strombus_. The last was defined as follows; "Testa obverse conica, nodosa, labium exterius angulum transversalem superne formans; interius nullum. Columella incurva. Cauda integra."

M. HAUSTELLUM. _M._ caudatus, subinermis, nodosus.

"Suturis" was originally "costis". The printed emendations are "gibbis, adglutinatis", "costati et nodosi", "subtus rima longitudinali clausa", "margine", and the final remark.

M. TRIBULUS. _M._ caudatus spinis subulatis trifariis.

"Olear. Mus. t. 39. f. 1" was cited in the transcript, to which Linnæus had added "Bonan. 269" and "List. t. 902. f. 22", all which synonyms are present in the 'Systema.' The printed additions are "suturis 3 longitudinalibus, adglutinatis, incrassatis", "secundum suturas: superficies transversim striis elevatis distinctis", "recta".

M. CORNUTUS. _M._ caudatus, spinis subulatis serie gemina.

The s. in the reference to Rumphius was a misprint for the written 5: "Pet. Gaz. t. 68. f. 12" (as in the 'Systema') was present in the copy. The expressions "striata", "conicæ", "obliquo situ", and the final remark, are the printed additions.

M. TRUNCULUS. _M._ subcaudatus, spinis simplici serie.

The description of the tail and account of the variety were not originally present: "suturis" was, at first, "plicis", and "adglutinatis" was "antrorsum adnatis".

M. RAMOSUS. _M._ dædaleus triangularis, spira longitudine ventris.

Had the original manuscript been printed, the multitude of species confused under this appellation would have been somewhat lessened. For the cited figures of _M. inflatus_ (Rumph. t. 26. f. A. and Gault. t. 38. f. A), with that of another short-spired _Murex_ (Arg. t. 19. f. C), were separated from the rest, and quoted for a _M. unguis-odor_, the brief definition of which was "_M._ dædalens triangularis, spira ventre breviore."

The published details, and the drawings of the longer-spired and more slender-bodied _Murices_ (Rumph. t. 26. f. l; d'Arg. t. 19. f. E, H.), appeared as _M. lichenoides_.

I consider, then, that in that event the _M. adustus_ (Arg. t. 19. f. H.), which would tolerably suit the definition, would have been considered the typical form, and _M. axicornis_ (Rumph. t. 26. f. l, and d'Arg. t. 19. f. E.), the variety γ.

M. SCORPIO. _M._ dædaleus quadrangularis, spira subcapitata.

The ill-judged final remark was not in the copy.

M. SAXATILIS. _M._ dædaleus quinquangularis, spira contigua.

The idea of this being a mere variety was not expressed in the original.

M. RANA. M. angulatus subdepressus, costis lateralibus.

The R. of d'Argenville was properly referred to the variety B. The "alba", "sulcis transversis", and "Dorsum anfractum simplici cingulo aculeato" were not in the copy.

M. LAMPAS. _M._ angulatus tuberculis nodosis, cauda flexuosa, labio interiore lævi.

The earlier reading of "una alterave ruga" was "uno alterove denticulo."

M. FEMORALE. _M._ angulato-triqueter: angulis antrorsum acuminatis.

The intended name was _M. triqueter_. Grew's engravings (f. 7, 8) of the species were correctly cited, and the erroneous reference to Rumphius was not inserted. The printed additions were unimportant--"exarata", "repando", "sub" before "edentula", and "levissime".

M. LOTORIUM. _M._ angulatus, tuberculis conicis, cauda flexuosa, labio interno rugoso.

"Subter" was a misprint for the written "inter": the "ut in proximis" was a printed addition.

M. RUBECULA. _M._ angulatus, sulcis moniliformibus, costis lateralibus, dorsalique.

"Gualt. t. 49. f. I" was rightly cited as illustrative: "ex" preceded "lineis".

M. RETICULARIS. _Cas._ inæqualis gibba reticulata, cauda elongata.

The erroneous reference to Rumphius was not present in the manuscript. As corroborative of my expressed belief in the identity of the species described in the 'Museum' with the _Triton ! mulus_, it may be observed, that our author has wholly separated this and the allied _anus_ from the true _Tritons_ and _Ranellæ_, and that the original heading corresponds accurately with the peculiar characteristics.

M. ANUS. _Cas._ inæqualis, gibba nodosa, labris rugosis.

"Pet. Gaz. t. 74. f. 9" and "Pet. Amb. t. 6. f. 4" were the unprinted synonyms. The "rugis reticulato-intertextis", "irregularis", and "patens" were emendations.

M. RICINUS. _M._ ecaudatus, ore utrinque dentato.

"Æqualibus, ad labium majoribus" was not in the copy.

M. CAPITELLUM. _M._ ecaudatus ovatus, columella rugosa, labio edentulo, superficie inermi rugosa.

"Alba" followed "edentula", and "Umbilicus ad basin" terminated the description in the original: the word "striis" was a subsequent introduction.

M. TURBINELLUS. _M._ ecaudatus, turbinatus, columella dentata, spinis explicatis.

The printed additions are "anteriores", "nodulosa", "alba", "Cauda vix ulla", and "Variat colore albo spira longiore".

M. CERAMICUS. _M._ ecaudatus, utrinque acuminatus, columella dentata, spinis conicis.

"Rumph. t. 49. f. L." was an unpublished synonym.

M. NODUS. _M._ ecaudatus ovatus, labio denticulato.

As "Gualt. t. 28. f. R." was quoted, and "aut nigris, conicis, obtusiusculis" (a character which probably belonged to some distinct species erroneously supposed to be a variety) was not inserted in the manuscript, I feel convinced that the _Purpura hystrix_ of authors was the species designed in the 'Museum Ulricæ.'

M. HYSTRIX. _M._ ecaudatus edentulus, fauce lævi.

M. MANCINELLA. _M._ ecaudatus, edentulus fauce striata.

This original heading, and the absence of the erroneous synonym from the MS., confirm the received opinion of the identity of the Museum species (not that of the 'Systema') with _Purpura mancinella_.

M. HIPPOCASTANUM. _M._ ecaudatus edentulus, fauce edentula integra, spinis serie triplici.

Gualtieri's erroneously cited figure was not indicated in the manuscript. No specific name had been originally attached to the description.

M. MELONGENA. _M._ ecaudatus edentulus fauce patula lævi, spinis serie duplici.

"Bonan. 3. f. 186" had been added to the synonymy by our author. The details were less copious than in the published edition, "apice solo acuminatus" being the meagre substitute for the entire description from "Spira" to the end.

M. FICUS. _Bul._ caudata, striis reticulatis, spira obtusa.

"Pet. Amb. t. 6. f. 9" was an omitted synonym. The shell described in the 'Museum' was assuredly not the _ficus_ of most writers.

M. RAPA. _Bul._ caudata, striis longitudinalibus, spira acuta.

M. FUSUS. _Turric._ caudata lævis, labio dentato.

"Bonan. f. 121" and the name had been added to the MS. by Linnæus.

M. BABYLONIUS. _Turric._ caudata, transversim angulo sulcata, labio marginali versus basim sinu exciso.

M. COLUS. _Turric._ caudata striata, labio exteriore crenato.

The printed emendations were "longa" and "s. angulati." The name was added by Linnæus. The following unnamed _Turricula_ succeeded the species in the manuscript copy:--

_T._ caudata striata, longitudinaliter sulcata.

Testa parva, striis plurimis secundum anfractus. Anfractus scabri, sulcis longitudinalibus 15. Color anfractuum superne griseus inferne pallidus. Apertura ovata. Rostrum baseos rectum, testæ dimidio brevius. Labium tantum exterius integrum. An filia præcedentis?

M. MORIO. _Strom._ spira subnodosa, labio exteriore intus rugoso.

The synonymy, as might be expected (for Seba was unknown to Linnæus when the descriptions were written), was not in the original.

M. COCHLIDIUM. _Strom._ spira pyramidata, anfractibus planis.

The reference to Seba, the name, and the "Cauda subulata, longitudine testæ" were not present.

M. CANALICULATUS. _Strom._ spira subconvexa, anfractibus distantibus.

The "Anfractus distincti canaliculo per omnes spiras," the name, and the reference to Seba, were the printed additions. "Habitat in Canada. Kalm." was appended.

M. ARUANUS. _Strom._ incurvus spinosus ventricosus, angulo obsoleto.

The objectionable name (for assuredly the _Buccinum Aruanum_ of Rumphius suits not "spinosus") was not present in the original, but had subsequently been added by our author, who seems to have erased the original "Habitat in Canada. Kalm." I doubt not that _Pyrula carica_ was intended.

M. PERVERSUS. _Strom._ inversus.

The wretched engraving of Gualtieri was not cited.

M. TRITONIS. _Cas._ pyramidalis lævis, columella dentata.

"Bonan. 3. f. 188" stood in the place of Seba. The printed additions were "plerisque", "et suturis variis alternis crassis", and the specific epithet. "Genus difficile eruitur" was written after the description, and the following note erased:--"Ad genus retuli ob labium interius adnatum in quibusdam latius, ob suturas verrucosas, ob caudam canaliculatam parum elevatam, ob labium postice dentatum, quæ omnia affinitatem arguunt."

The _Triton nodiferus_ was probably designed by the following description, which succeeded that of _M. Tritonis_:--

_Cas._ (corrected by Linnæus to _Murex_) _Neptuni_. _C._ pyramidalis nodosa, columella dentata.

Testa maxime facie statura et colore præcedentis. Anfractuum angulus summus nodis prominentibus, unde et spira nodosa evadit, quod non in præcedente. Apertura præcedentis. Labium interius magis dilatatum, maximeque planum. Columella non dentata. Habitat Constantinopoli. Edw. Carleson.

M. TRAPEZIUM. _Strom._ spira nodosa, labio denticulato, columella rugosa.
