Chapter II: Part 2

Length of specimen, 12 mm.

Color white or flesh color.

The specimens were collected during the latter part of July at Laguna Beach, from the seaweed in the inner tide pools.

_Caprella æquilibra_ Say

The peræon (Plate IV, Fig. 12) is comparatively smooth, with the cephalon devoid of a horizontal spine; the first three segments are long and narrow, of nearly equal length, the fourth a little longer than the third, the fifth twice as long as the sixth and seventh combined. The branchia are ovate in shape and moderate in size. Between the bases of the second gnathopods is a sharp projection (Fig. 13), and on each side another spiniform process pointing anteriorly. Superior antennæ slightly over half as long as the body, first joint about half as long as the second, but broader; second twice as long as the first, and third a little longer than the first, but narrower; flagellum with sixteen or seventeen joints and about as long as the peduncle. Inferior antennæ reaching just beyond the peduncle of the superior. First gnathopod small, attached far forward, palm triangular in shape, tapering toward the finger, which reaches back entirely over the inner margin of the palm, armed with two sharp spine-like teeth at the base of the palm, and scattered hairs. Second gnathopod (Fig. 14), attached at the posterior end of the segment, basal joint quite short; other joints have their lobes ending in spine-like processes; palm slightly convex on the inner margin, with a spined lobe about a third of the way along, and a blunt tooth two-thirds of the way along separated from a broad tooth by a deep sinus; claw regularly concave; whole gnathopod with but few hairs. Third, fourth and fifth peræopods (Fig. 15) similar in size and structure; palm thick, with two serrate teeth a third of the distance from the base.

Length of specimen, 12 mm.

Color a dark brown to flesh color.

Two specimens taken on a holdfast that was thrown up on the beach at Laguna Beach during July, 1914.

Record of Two Fish, Not Before Mentioned, from Laguna

During the summer of 1914 no special effort was made to collect fish, but the two following species were taken:

_Porichthys notatus_ Girard

A specimen of this interesting but rather common Californian fish was taken in a tide pool and kept for some time alive in the aquarium. This is sometimes called "Midshipman," because of the bright metallic spots over the head and body, like the buttons on a midshipman's uniform of years ago. These spots are provided with a lens, connective tissue capsule and a reflector, and are supposed to be luminous.

_Mola mola_ Linnæus

A small specimen of this head-fish, or sunfish, was brought to us by the fisherman.

Note on the Sea Urchins of Laguna Beach

Due to the kindness of Dr. H. L. Clark of Harvard, we are able now to have some clearer idea about the number of species of sea urchins found at Laguna.

_Strongylocentrotus purpuratus_ Stimp

This is our most common species. It occurs by the hundreds in some of the larger tide pools, such as those near Seal Rocks. Judging from the specimens sent to Dr. Clark, the rather common greenish form, which we supposed to be distinct at first, is simply a younger form of the same species. This greenish form is more often found nearer shore under stones, where quite small individuals are abundant.

_S. franciscanus_ A. Agassiz

These larger urchins are not so common as they may have been. Larger specimens may be obtained under rock ledges in deep water. Smaller forms of the same species, which seem to have long reddish spines, may be found in the tide pools, but are not common.

Additional Notes on the Birds of Laguna Beach

LEON L. GARDNER

In accordance with the general plan of the Laguna Marine Laboratory, a part of the work was with the birds of the locality.

As mentioned in the First Annual Report of the Laboratory, Laguna Lakes, about four miles up Laguna Canyon; Balboa, eight miles up the coast, and the surrounding rocky wild hills of Laguna, afford rich and varied collecting. Perhaps the richest area of bird life lies between Laguna and Balboa, in the Irvine Ranch. This is a large tract of land comprising many thousands of acres, extending about seven miles up the coast from Laguna and eleven miles inland. The canyons here are steep and, in some localities, very wooded in contrast to the more open canyons farther down the coast. For years this land has been given over to cattle grazing, and the Irvine company, in order to safeguard the stock, have allowed no one, except their own range riders, to enter the property. In the years 1911 and 1912 this was a state game preserve, and there is considerable rumor among local residents that it was stocked with some kind of pheasants. However, I have neither seen nor heard of a specimen taken. In all events, the protection afforded the birds has been taken advantage of, and quail, road-runners, many species of hawks and all of the smaller birds thrive in abundance and safety.

The fifteen days of collecting were spent largely in covering as large an area as possible, to obtain the widest range of representative species, with field notes, etc., to be placed in the Laboratory building, as a nucleus for greater collections and for the benefit of the local residents or summer visitors who are interested in the work of the College.

The additions to the first list, published in the First Annual Report, as mentioned before, are as follows:

_Gavia immer_ (Brünnich) Common Loon

A specimen taken in Balboa Bay, July 6, 1914. This is rather an unusual record, as the Loon is only a winter visitant; however, some are known to remain throughout the summer. Mr. Swarth tells me that this specimen had lost the power of flight during its molt. He thinks this seems to indicate that Loons lose the ability to fly during molting, as do the Anseres.

_Gavia pacifica_ (Lawrence.) Pacific Loon

June 27, I found a dead Pacific Loon cast up on the beach. The specimen was in very worn and oddly colored plumage. On examination Mr. Swarth said it was a partial albino and had skipped a regular molt.

_Larus heermanni_ Cassin. Heermann Gull

Abundant about the Bay at Balboa.

_Mergus serrator_ Linn. Red-breasted Merganser

A female taken July 6, 1914. This is a very late record for this bird, since it leaves mostly in April. It was found resting on a sand spit in Balboa Bay.

_Oidemia perspicillata_ (Linn.) Surf Scoter

Common along the coast from Laguna to Balboa.

_Oidemia deglandi_ Bonaparte. White-winged Scoter

Occurring with the preceding species.

_Erismatura jamaicensis_ (Gmelin). Ruddy Duck

Occurring at the tule lake in Laguna Canyon.

_Himantopus mexicanus_ (Müller). Black-necked Stilt

One taken at Laguna Lakes, now mounted and in possession of J. N. Isch, Laguna Beach.

_Macrorhamphus griseus scolopaceus_ (Say)

Long-billed Dowitcher

A specimen taken on the sand spits in Balboa Bay, July 6, 1914. This appears to be an early fall migration record.

_Catoptrophorus semipalmatus inornatus_ (Brewster)

Western Willet.

Abundant in August, less common in July. Often in company with Hudsonian curlews (_Numenius hudsonicus_) along the coast. One taken as early as July 6.

_Heteractitis incanus_ (Gmelin). Wandering Tattler

Found in August along the rocky coast by Arch Beach (down the coast from Laguna).

_Actitis macularius_ (Linn). Spotted Sandpiper

Common along the beach in August.

_Ægialitis semipalmata_ (Bonaparte). Semipalmated Plover

A small flock found at Balboa July 13.

_Ægialitis novisa_ Cassin. Snowy Plover

One taken between Laguna and Balboa.

_Buteo borealis calurus_ Cassin. Western Red-tail

Fairly common in the hills. There seemed to be several different species of hawks at Laguna, but as they were very shy and most of them took refuge in the forbidden territory of the Irvine Ranch, none of the larger ones were obtained.

_Haliætus leucocephalus leucocephalus_ (Linn.) Bald Eagle.

There are five Bald Eagles that are commonly seen along the beach near Laguna. When followed, they are always found to come to rest on the high, rocky west slope of Aliso Canyon (down the coast from Laguna). The owner of the canyon, Mr. Joe Thurston, tells me that for years a pair has bred there, and these other three are young that did not leave the vicinity. He is very jealous of their safety, and it is to be hoped they may always be kept there as a natural attraction. This is one of the few breeding points along the coast from which the Bald Eagle has not been driven. In March, 1895, Mr. E. Davis took two fresh eggs of the Bald Eagle near Laguna Beach. It would be very interesting to know whether or not he obtained them from the same canyon; if so, this must be a very old breeding place.

_Pandion haliætus carolinensis_ (Gmelin). Osprey

One shot from a flagstaff in the center of town. The date is uncertain, but appears to be about 1905. The specimen is now mounted and in the possession of Mr. J. N. Isch of Laguna.

_Otus asio bendirei_ (Brewster). California Screech Owl

Fairly common in the timbered canyons.

_Speotyto cunicularia hypogaea_ (Bonaparte). Burrowing Owl

Common in upper Aliso Canyon, which is more open and very hot and arid.

_Ceryle alcyon_ (Linn.) Belted Kingfisher

I noted two birds which were undoubtedly of this species along a rocky stretch of the coast, but was unable to collect one.

_Melanerpes formicivorus bairdi_ Ridgway. California Woodpecker

I obtained two specimens of this species from a flock in Nigger Canyon. This seems to be a very low altitude at which to find these birds.

_Myiochanes richardsoni richardsoni_ (Swainson).

Western Wood Pewee

I collected two of this species in the willow bottoms July 25, 1912, which seems to be an indication that they are summer residents.

_Corvus corax sinuatus_ Wagler. Raven

Irregular along the coast. One collected July 19.

_Astraglinus tristis salicamans_ (Grinnell). Willow Goldfinch

Common in the willow bottoms.

_Ammodramus savannarum bimaculatus_ Swainson

Western Grasshopper Sparrow

Very common in one particular grassy glade at the top of the ridge around Laguna, also at the tule lakes. I took a young bird June 27, which seems to indicate the birds were breeding there. This is one of the few breeding records for Southern California.

_Hirundo erythrogastra_ Boddaert. Barn Swallow

Common along the rocky cliffs; some breeding in July.

This concludes the additional list. There is one other breeding record worthy of note. In Nigger Canyon (Irvine Ranch) there is a Great Blue Heron nesting colony. Although such colonies were at one time common along the coast, they are now becoming rare. The colony is situated in a large clump of sycamore trees, in the bottom of the canyon, some half mile or more inland. There are about thirty nests, quite white with bird lime; the trees and ground also are well covered, showing the permanency of the site. On June 26, 1914, I visited the colony and found very young birds, but no eggs. The whole place was filled with a peculiar stench, while the croakings of the old birds, coupled with the frightened squawks of the young, and the invisible, choking powder down, made the place quite undesirable. The old birds were very bold, but not pugnacious, and while the examination of the nests went on retired to nearby trees to watch the proceedings, while the young crowded out to the uttermost branches, keeping up a continual racket.

Owing to the protection afforded by the Irvine ranch, the colony has thrived and probably will for an indefinite period.

A New Dipterous Gall on Stanleya

T. D. A. COCKERELL

On June 18, 1914, my wife and I found a hitherto undescribed gall on _Stanleya glauca_ Rydberg, a remarkable cruciferous plant growing about four miles north of Boulder, Colorado. Thinking to rear the adults, the galls were placed in a bottle with some earth and watched for a long time, but nothing appeared. Supposing the effort to have been unsuccessful, I set the bottle aside; but long after discovered that adults had eventually emerged, but had died and were covered with mold. I was able to rescue sufficient fragments to make the drawings given herewith, which, together with the larval characters, serve very well to indicate the genus, with enough of the specific characters for ready recognition. The species may be called

_Perrisia Stanleyae_ n. sp. (Cecidomyiidæ)

_Gall_: A swollen flower of _Stanleya glauca_, containing many pallid larvæ. The sepals are thickened and enlarged.

_Larva_: With the skin strongly verrucose; breastbone of the same general type as that of _P. fructicola_ Kieffer; caudal end with strong spines.

_Male_: The characteristic genitalia and antennal joint are figured.

Hydroids of Laguna Beach

PROF. A. M. BEAN

PACIFIC UNIVERSITY, FOREST GROVE, OREGON

The identification of the hydroids included in this list was undertaken while making a general collection of the marine forms of the Laguna Beach region. The specimens were taken mostly from the miscellaneous shore collections, and there is no claim to exhaustiveness. They were, however, examined as fresh material, and nearly always with the living polyp still present. There was abundant promise of opportunity for the study of ecological and developmental problems, of which I was unable at that time to take advantage.

The region covered included a strip of shore line of about two miles in extent. Part of this is sandy beach which after a heavy tide would often be covered by the laminæ and holdfasts of _Macrocystis_ and other kelps, to which hydroids were generally attached. The remainder of the shore was rocky and of a remarkably varied conformation, including tide pools, deep channels, rock tables, mussel beds, and short stretches of sand and pebbly beach. Scarcely any attempt was made at dredging, and the shore itself was by no means completely searched.

GYMNOBLASTEA

Family PENNARIIDÆ

_Tubularia_ sp.

This single representative of the Gymnoblastea more nearly corresponds to the _T. marina_ described by Torrey, '02. It is, however, much smaller, the erect branches being scarcely ever as much as 15 mm. in length, instead of 30-50 mm. The proximal tentacles are 28 and 29 in number, instead of 22-26, described for _T. marina_. There is very little appearance of annulation of the stem, and no evidence of the "stem increasing in diameter distally." The habitat is also different. _T. marina_ is given as growing "between tides on the lee side of rocks exposed to the breakers of the open sea." The tubularian in question, however, was found only clustered in among the rootlike holdfasts of the _Macrocystis_ at a depth of four to six fathoms. Moreover _T. marina_ is not reported as occurring farther south than Pacific Grove. There seems to be some reason for considering this a new species, but further investigation, and perhaps a study of comparative material, will be necessary to determine its systematic position.

CALYPTOBLASTEA

Family SERTULARIIDÆ

_Sertularella tricuspidata_ (Alder)

_Sertularia furcata_ (Trask)

Both of the above forms were found on the washed-up holdfasts of _Macrocystis_.

Family PLUMULARIIDÆ

_Aglaophenia inconspicua_ (Torrey '02)

Torrey's description gives "hydrocladia 3-4 mm. long." Out of a large number examined, however, I found none with hydrocladia more than 1.5 mm.

_Aglaophenia struthionides_ (Murray)

Both _A. inconspicua_ and _A. struthionides_ were taken from the red algæ brought in by the tides.

_Plumularia setacea_ (Ellis)

This form appears to have a wide variation in its bathymetric distribution. Specimens were collected from the mussels which are uncovered at mid-tide, and from the carapace of _Loxorhynchus grandis_, a deep-sea crab that is only rarely brought to shore by the highest tides.

_Plumularia lagenifera_ (Allman)

Found on kelp holdfasts.

_Antenella avalonia_ (Torrey)

Taken in tow-net from floating red algæ.

Family CAMPANULARIIDÆ

Mention may be made here of one of the Campanulariidæ recently sent me by Professor Hilton of Pomona College, to whom thanks are due for many courtesies. It does not appear to be any species yet reported from this coast. Its identification, or at least an adequate description, must, however, be postponed for a future paper.

Summer School at Laguna Beach

During the six weeks of summer school of the past season (1914) there were in attendance about thirty students and investigators, some of whom remained until the middle of September. In addition to these there were several hundred visitors to the aquarium and laboratory, in spite of the bad condition of the roads. After the middle of the summer running salt water was piped to the laboratories and aquaria, so that it was much easier to keep specimens alive. Yet even before this many interesting forms were on exhibition. At all times there were numerous marine animals for study, as well as many living land species, such as tarantulas, lizards, frogs, a large turtle and a number of snakes. Several rattlesnakes were kept in a box in the front of the building until the end of the summer. Several of the largest rattlesnakes were an unending source of interest. One day several people were able to observe a king snake swallow a slightly smaller rattler.

From day to day a varied display of marine forms was to be found in the aquarium; at different times rare and curious fish, starfish, sea urchins and devilfish, while now and then some of the larger specimens, such as sharks and rays, were brought in. Some of these were kept alive in the large cement floor tank or in the larger jars. Great quantities of smaller specimens were no less interesting, such as sea spiders, serpent stars of many beautiful colors and markings, brilliant nudibranchs, large abalones, curious small crabs and, in fact, all the interesting or beautiful specimens that could be found.

Each week, until September, the public was also invited to attend the evening lectures. These were usually of a general nature relating to the life of the sea, but some told of land forms as well, and one was on the Hopi Indian Snake Dance.

The chief work of the laboratory during the first six weeks was in connection with the Summer School. There was a class of nine in General Biology, twelve in General Zoology, and five in General Entomology. There were, in addition, from six to twelve doing special work for a longer or shorter period. Students from three Pacific coast colleges were in attendance, although most of the students and advanced workers were from Pomona College. Two or three studied special Histological or Embryological topics, but the majority were interested in faunal and distributional problems. As announced at an earlier time, the Laguna station is but an extension of the Biological part of Pomona College, and the plan for special work includes a survey of the whole region from the mountains to the sea. With this in mind, many explorations have been begun, and the aid of specialists in various fields is sought, so that we may first of all know the living forms that inhabit this varied and interesting section of California. We hope that a better knowledge of the species in the different groups here may lead to more extensive observations both by advanced students from the College and by others.

Together with the special and general work of the students, collections of marine and land animals were obtained all through the summer. Some of these were for the local collection, others to aid in the work of the survey. Among the collections made were many species of sponges, hydroids, polyzoans, pycnogonids, marine worms, Crustacea of several groups and, in fact, nearly all the shore forms that could be obtained between tides or a short distance from shore with a small boat. There were also extensive collections of insects and spiders from the hills and from up and down the coast.

For the study of marine and land animals Laguna has proved itself once more well adapted to our uses. The high hills come down near the ocean at several points, and there are miles of interesting and varied coast line in both directions from the laboratory. All summer, students in small or larger parties tramped over the hills and through the many interesting canyons to the lakes, to the Mission of San Juan Capistrano, or to Balboa and the mud flats. Saturday was the regular field day, and the longer tramping trips were then taken, but very often of an evening groups of students enjoyed beach suppers or picnics in some canyon or up in the hills.

That Laguna and its surroundings is a region of great interest and beauty is evinced by the fact that a number of artists make it their home, while it is visited by many others. The trail to Balboa, along the beach or the cliffs, is wonderfully varied and beautiful, while the drive from Laguna to San Juan Capistrano, except for the lack of villages and ruins, might well be considered a part of the famous Amalfi Sorrento drive in Italy.

During the summer of 1915 courses in general as well as special zoology will be given. General entomology may also be studied with advantage. For those who are just beginning biological work there may be special exercises arranged, as last summer.

There are eight private rooms in the laboratory for special workers. Some of these will be available for investigators who may wish to follow out problems of their own or those suggested by the work of the station. Write

Pomona College

Located in one of the most healthful and beautiful parts of the west coast. The mountains reach an elevation of ten thousand feet within a few miles of the college and these with the nearby ocean afford many special advantages for the study of things not in books. The college is a small one of the New England type with high standards of scholarship. A large proportion of the graduates go on with advanced work in the large universities. In addition, well-manned departments of music and art afford exceptional advantages.
