Chapter II: History and Literature From 1880

In the systematic account which followed the above chapter in the 9th edition of the _Encyclopaedia Britannica_, the following classification, which is the same as that given in the author's _Introduction to the Study of Fishes_ (London, 1880) was adopted by Albert Günther:--

Subclass I. : PALAEICHTHYES.
Order I. : _Chondropterygii._
With two suborders : Plagiostomata and Holocephala.
Order II. : _Ganoidei._
With eight suborders : Placodermi, Acanthodini, Dipnoi,
Chondrostei, Polypteroidei, Pycnodontoidei, Lepidosteoidei,
Amioidei.

Subclass II. : TELEOSTEI.
Order I. : _Acanthopterygii._
With the divisions Perciformes, Beryciformes, Kurtiformes,
Polynemiformes, Sciaeniformes, Xiphiiformes, Trichiuriformes,
Cotto-Scombriformes, Gobiiformes, Blenniformes, Mugiliformes,
Gastrosteiformes, Centrisciformes, Gobiesociformes, Channiformes,
Labyrinthibranchii, Lophotiformes, Taeniiformes and
Notacanthiformes.
Order II. : _Acanthopterygii Pharyngognathi._
Order III. : _Anacanthini._
With two divisions : Gadoidei and Pleuronectoidei.
Order IV. : _Physostomi._
Order V. : _Lophobranchii._
Order VI. : _Plectognathi._

Subclass III. : CYCLOSTOMATA.

Subclass IV. : LEPTOGARDII.

It was an artificial system, in which the most obvious relationships of the higher groups were lost sight of, and the results of the already fairly advanced study of the fossil forms to a great extent discarded. This system gave rise to much adverse criticism; as T. H. Huxley forcibly put it in a paper published soon after (1883), opposing the division of the main groups into Palaeichthyes and Teleostei: "Assuredly, if there is any such distinction to be drawn on the basis of our present knowledge among the higher fishes, it is between the Ganoids and the Plagiostomes, and not between the Ganoids and the Teleosteans"; at the same time expressing his conviction, "first, that there are no two large groups of animals for which the evidence of a direct genetic connexion is better than in the case of the Ganoids and the Teleosteans; and secondly, that the proposal to separate the Elasmobranchii (Chondropterygii of Günther), Ganoidei and Dipnoi of Müller into a group apart from, and equivalent to, the Teleostei appears to be inconsistent with the plainest relations of these fishes." This verdict has been endorsed by all subsequent workers at the classification of fishes.

Günther's classification would have been vastly improved had he made use of a contribution published as early as 1871, but not referred to by him. As not even a passing allusion is made to it in the previous chapter, we must retrace our steps to make good this striking omission. Edward Drinker Cope (1840-1897) was a worker of great originality and relentless energy, who, in the sixties of the last century, inspired by the doctrine of evolution, was one of the first to apply its principles to the classification of vertebrates. Equally versed in recent and fossil zoology, and endowed with a marvellous gift, or "instinct" for perceiving the relationship of animals, he has done a great deal for the advance of our knowledge of mammals, reptiles and fishes. Although often careless in the working out of details and occasionally a little too bold in his deductions, Cope occupies a high rank among the zoologists of the 19th century, and much of his work has stood the test of time.

The following was Cope's classification, 1871 (_Tr. Amer. Philos. Soc._ xiv. 449).

Subclass I. Holocephali.
" II. Selachii.
" III. Dipnoi.
" IV. Crossopterygia, with two orders: Haplistia and Cladistia.
" V. Actinopteri.

The latter is subdivided in the following manner:--

Tribe I. : Chondrostei.
Two orders : Selachostomi and Glaniostomi.
Tribe II. : Physostomi.
Twelve orders: Ginglymodi, Halecomorphi, Nematognathi, Scyphophori,
Plectospondyli, Isospondyli, Haplomi, Glanencheli, Ichthyocephali,
Holostomi, Enchelycephali, Colocephali.
Tribe III. : Physoclysti.
Ten orders : Opisthomi, Percesoces, Synentognathi, Hemibranchii,
Lophobranchii, Pediculati, Heterosomata, Plectognathi, Percomorphi,
Pharyngognathi.

Alongside with so much that is good in this classification, there are many suggestions which cannot be regarded as improvements on the views of previous workers. Attaching too great an importance to the mode of suspension of the mandible, Cope separated the Holocephali from the Selachii and the Dipnoi from the Crossopterygii, thus obscuring the general agreement which binds these groups to each other, whilst there is an evident want of proportion in the five subclasses. The exclusion from the class Pisces of the Leptocardii, or lancelets, as first advocated by E. Haeckel, was a step in the right direction, whilst that of the Cyclostomes does not seem called for to such an authority as R. H. Traquair, with whom the writer of this review entirely concurs.

The group of Crossopterygians, first separated as a family from the other Ganoids by Huxley, constituted a fortunate innovation, and so was its division into two minor groups, by which the existing forms (_Polypteroidei_) were separated as Cladistia. The divisions of the Actinopteri, which includes all Teleostomes other than the Dipneusti and Crossopterygii also showed, on the whole, a correct appreciation of their relationships, the Chondrostei being well separated from the other Ganoids with which they were generally associated. In the groupings of the minor divisions, which Cope termed orders, we had a decided improvement on the Cuvierian-Müllerian classification, the author having utilized many suggestions of his fellow countrymen Theodore Gill, who has done much towards a better understanding of their relationships. In the association of the Characinids with the Cyprinids (Plectospondyli) in the separation of the flat-fishes from the Ganoids, in the approximation of the Lophobranchs to the sticklebacks and of the Plectognaths to the Acanthopterygians, and in many other points, Cope was in advance of his time, and it is to be regretted that his contemporaries did not more readily take up many of his excellent suggestions for the improvement of their systems.

In the subsequent period of his very active scientific life, Cope made many alterations to his system, the latest scheme published by him being the following ("Synopsis of the families of Vertebrata," _Amer. Natur._, 1889, p. 849):--

Class : Agnatha.
I. Subclass : OSTRACODERMI.
Orders : Arrhina, Diplorrhina.
II. Subclass : MARSIPOBRANCHII.
Orders : Hyperotreti, Hyperoarti.

Class : Pisces.
I. Subclass : HOLOCEPHALI.
II. Subclass : DIPNOI.
III. Subclass : ELASMOBRANCHII.
Orders : Ichthyotomi, Selachii.
IV. Subclass : TELEOSTOMI.
(i.) Superorder : _Rhipidopterygia._
Orders : Rhipidistia, Actinistia.
(ii.) Superorder : _Crossopterygia._
Orders : Placodermi, Haplistia, Taxistia, Cladistia.
(iii.) Superorder : _Podopterygia_ (Chondrostei).
(iv.) Superorder : _Actinopterygia._
Orders : Physostomi, Physoclysti.

This classification is that followed, with many emendations, by A. S. Woodward in his epoch-making _Catalogue of Fossil Fishes_ (4 vols., London, 1889-1901), and in his most useful _Outlines of Vertebrate Paleontology_ (Cambridge, 1898), and was adopted by Günther in the 10th edition of the _Encyclopaedia Britannica_:--

Class : Agnatha.
I. Subclass : CYCLOSTOMI.
With three orders : (a) _Hyperoartia_ (Lampreys); (b)
_Hyperotreti_ (Myxinoids); (c) _Cycliae_ (Palaeospondylus).
II. Subclass : OSTRACODERMI.
With four orders : (a) _Heterostraci_ (Coelolepidae,
Psammosteidae, Drepanaspidae, Pteraspidae); (b) _Osteostraci_
(Cephalaspidae, Ateleaspidae, &c.); (c) Antiarchi
(Asterolepidae, Pterichthys, Bothrolepis, &c.); (d) Anaspida
(Birkeniidae).

Class : Pisces.
I. Subclass : ELASMOBRANCHII.
With four orders : (a) _Pleuropterygii_ (Cladoselache); (b)
_Ichthyotomi_ (Pleuracanthidae); (c) _Acanthodii_
(Diplacanthidae, and Acanthodidae); (d) _Selachii_ (divided
from the structure of the vertebral centres into
Asterospondyli and Tectospondyli).
II. Subclass : HOLOCEPHALI.
With one order : _Chimaeroidei._
III. Subclass : DIPNOI.
With two orders : (a) _Sirenoidei_ (Lepidosiren, Ceratodus,
Uronemidae, Ctenodontidae); (b) _Arthrodira_ (Homosteus,
Coccosteus, Dinichthys).
IV. Subclass : TELEOSTOMI.
A. Order : _Crossopterygii._
With four suborders: (1) _Haplistia_ (Tarassius); (2)
_Rhipidistia_ (Holoptychidae, Rhizodontidae, Osteolepidae);
(3) _Actinistia_ (Coelacanthidae); (4) _Cladistia_
(Polypterus).
B. Order : _Actinopterygii._
With about twenty suborders: (1) _Chondrostei_
(Palaeoniscidae, Platysomidae, Chondrosteidae, Sturgeons);
(2) _Protospondyli_ (Semionotidae, Macrosemiidae,
Pycnodontidae, Eugnathidae, Amiidae, Pachycormidae); (3)
_Aetheospondyli_ (Aspidorhynchidae, Lepidosteidae); (4)
_Isospondyli_ (Pholidophoridae, Osteoglossidae, Clupeidae,
Leptolepidae, &c.); (5) _Plectospondyli_ (Cyprinidae,
Characinidae); (6) _Nematognathi_; (7) _Apodes_; and the
other Teleosteans.

There are, however, grave objections to this system, which cannot be said to reflect the present state of our knowledge. In his masterly paper on the evolution of the Dipneusti, L. Dollo has conclusively shown that the importance of the autostyly on which the definition of the Holocephali from the Elasmobranchii or Selachii and of the Dipneusti from the Teleostomi rested, had been exaggerated, and that therefore the position assigned to these two groups in Günther's classification of 1880 still commended itself. Recent work on _Palaeospondylus_, on the Ostracoderms, and on the Arthrodira, throws great doubt on the propriety of the positions given to them in the above classification, and the rank assigned to the main divisions of the Teleostomi do not commend themselves to the writer of the present article, who would divide the fishes into three subclasses:--

I. Cyclostomi
II. Selachii
III. Teleostomi,

the characters and contents of which will be found in separate articles; in the present state of uncertainty as to their position, _Palaeospondylus_ and the _Ostracodermi_ are best placed _hors cadre_ and will be dealt with under these names.

The three subclasses here adopted correspond exactly with those proposed in Theo. Gill's classification of the recent fishes ("Families and Subfamilies of Fishes," _Mem. Nat. Ac. Sci._ vi. 1893), except that they are regarded by that authority as classes.

The period dealt with in this chapter, ushered in by the publication of Günther's _Introduction to the Study of Fishes_, has been one of extraordinary activity in every branch of ichthyology, recent and fossil. A glance at the _Zoological Record_, published by the Zoological Society of London, will show the ever-increasing number of monographs, morphological papers and systematic contributions, which appear year after year. The number of new genera and species which are being proposed is amazing, but it is difficult to tell how many of them will simply go to swell the already overburdened synonymy. Perhaps a reasonable estimate of the living species known at the present day would assess their number at about 13,000.

It is much to be regretted that there is not a single general modern systematic work on fishes. The most important treatises, the 7th volume of the _Cambridge Natural History_, by T. W. Bridge and G. A. Boulenger, and D. S. Jordan's _Guide to the Study of Fishes_, only profess to give definitions of the families with enumerations of the principal genera. Günther's _Catalogue of the Fishes in the British Museum_ therefore remains the only general descriptive treatise, but its last volume dates from 1870, and the work is practically obsolete. A second edition of it was begun in 1894, but only one volume, by Boulenger, has appeared, and the subject is so vast that it seems doubtful now whether any one will ever have the time and energy to repeat Günther's achievement. The fish fauna of the different parts of the world will have to be dealt with separately, and it is in this direction that descriptive ichthyology is most likely to progress.

North America, the fishes of which were imperfectly known in 1880, now possesses a _Descriptive Catalogue_ in 4 stout volumes, by D. S. Jordan and B. W. Evermann, replacing the synopsis brought out in 1882 by D. S. Jordan and C. H. Gilbert. A similar treatise should embrace all the fresh-water species of Africa, the fishes of the two principal river systems, the Nile and the Congo, having recently been worked out by G. A. Boulenger. Japanese ichthyology has been taken in hand by D. S. Jordan and his pupils.

The fishes of the deep sea have been the subject of extensive monographs by L. Vaillant (_Travailleur_ and _Talisman_), A. Günther (_Challenger_), A. Alcock (_Investigator_), R. Collett (_Hirondelle_), S. Garman (_Albatross_) and a general résumé up to 1895 was provided in G. B. Goode's and T. H. Bean's _Oceanic Ichthyology_. More than 600 true bathybial fishes are known from depths of 1000 fathoms and more, and a great deal of evidence has been accumulated to show the general transition of the surface fauna into the bathybial.

A recent departure has been the exploration of the Antarctic fauna. Three general reports, on the results of the _Southern Cross_, the _Belgica_ and the Swedish _South Polar_ expeditions, had already been published in 1907, and others on the _Scotia_ and _Discovery_ were in preparation. No very striking new types of fishes have been discovered, but the results obtained are sufficient to entirely disprove the theory of bipolarity which some naturalists had advocated. Much has been done towards ascertaining the life-histories of the fishes of economic importance, both in Europe and in North America, and our knowledge of the larval and post-larval forms has made great progress.

Wonderful activity has been displayed in the field of palaeontology, and the careful working out of the morphology of the archaic types has led to a better understanding of the general lines of evolution; but it is to be regretted that very little light on the relationships of the living groups of Teleosteans has been thrown by the discoveries of palaeontologists.

Among the most remarkable additions made in recent years, the work of R. H. Traquair on the problematic fishes _Palaeospondylus_, _Thelodus_, _Drepanaspis_, _Lanarkia_, _Ateleaspis_, _Birkenia_ and _Lanasius_, ranks foremost; next to it must be placed the researches of A. S. Woodward and Bashford Dean on the primitive shark _Cladoselache_, and of the same authors, J. S. Newberry, C. R. Eastman, E. W. Claypole and L. Hussakof, on the Arthrodira, a group the affinities of which have been much discussed.
