HERTLEIN Leland Stanford Junior University In a study of a collection of Tertiary fossils from Lower California, a considerable number of species of Pectens were identified, several of which appear to be undescribed. The writer wishes to acknowledge the kind help received from Dr. J. P. Smith of the Leland Stanford Junior University ; he also wishes to thank Dr. G. Dallas Hanna and Mr. Eric K. Jordan of the California Academy of Sciences for the loan of Acad- emy material and helpful criticism of the manuscript. Permis- sion by Dr. B. L. Clark to examine material in the collection of the University of California is gratefully acknowledged. Acknowledgment is also due especially to Mr. C. H. Beal and to Messrs. B. F. Hake, C. R. Swarts and T. J. Cullen of the Marland Oil Company of California; and also to Mr. E. Call Brown of Los Angeles, California, for the material col- lected by them. The greater part of this material is now in the paleontological collections of the Leland Stanford Junior University; paratypes where available, and duplicates, are in the collections of the California Academy of Sciences. Previously described species of Pectens recognized in the collection are listed as follows, together with the L.S.J.U. and C.A.S. locality numbers from Lower California, and with the July 21, 1925 2 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. formation as far as known.

Pecten (Plagioctenium) cerros7 specimens collected at Kong-Ju, Korea, June 10, 1911, 33 have some web between the third and fourth fingers, while four (Nos. 32957, 32966, 32971, 32975) have no web between these fingers. All of the four have loreal dark streaks, and these streaks are clearly shown, also, by all of the 33 except No. 32958, which has none, and Nos. 32950 and 32965, each of which has a mere trace. Loreal streaks are present in all our other Korean Hylas except two from Wonsan. These are No. 32929, in which there is a trace of the stripe, and No. 32932, in which the stripe is entirely wanting. Both have finger webs. 32887 to 22926. Fusan, Kjong-San-Do Province, May 6, 1911. 32927 to 32940. Wonsan, Kang-Won-Do Province, June 7, 1911. 32941 to 32977.

Cacopoides borealis Barbour A large series of this little known species was secured at Chiksan, Korea, June 16, 1911 (Nos. 32520 to 32572 and Nos. 35939 to 35944). It may be supposed that the species was breeding at that time. Some of the specimens are nearly Q2 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. black over all of the upper surfaces. Others are quite light in general coloration, with various cloudings, blotches, spots or dots of dark brown, slate or black. The light ground color in the less pigmented specimens may be gray or pale brown, sometimes with a trace of pink. 7. Rana chinensis Osbeck Our Korean collections include about 109 specimens of this frog. They seem to show no difference in any way between Japanese and Chinese specimens. Frequently there is no dorsal line or band. Such specimens may resemble Rana plancyi, but may be readily distinguished by their dorsal dermal ridges which are lacking in Rana plancyi. 32766 to 32790.

Rana temporaria Linnaeus Our Korean collections include numerous frogs of the tem- poraria group. There is much variation, particularly in the position of the vomerine teeth, in specimens from the same locality. To the name Rana temporaria have been referred specimens which agree in having the dorsolateral ridge flaring out anteriorly toward the tympanum, the snout short, the web large or very large, and no definite light line along the upper jaw. The vomerine teeth may be between the choanae (asinNos. 32727, 32763), between and behind (as in Nos. 32748, 32750, 32751, 32762, 32765), or behind the choanse (as in Nos. 32749, 32752, 32753, 32764). The outer metatarsal tubercle may be absent (No. 32749), but is present in nearly all. 32700 to 32726. Pu-Ryong, Ham-Gjong-Do Province, May 22, 1911. ^2127.

Rana japonica (Giinther) The frogs which have been referred to this species agree in the possession of dorsolateral ridges which either are very in- distinct or wanting anteriorly, or run forward without bending out much toward the tympanum, long snouts, small webs, and usually a very distinct light line along the upper jaw. The vomarine teeth vary in position as they do in Rana temporaria, being sometimes between the choanse (as in Nos. 32738, 32740, 32745, 32747), sometimes between and behind (as in Nos. 32728, 32731, 32733, 32735, 32736, 32737, 32739, 32741, 32742, 32743, 32746), and sometimes quite behind the choanae (as in Nos. 32729, 32730, 32732, 32734, 32744). The outer metatarsal tubercle is usually absent (32729, 32730, 32731, 32733), but may be present on one side only (36006, 36008) or on both sides (32728, 32732, 36028). Nos. 36029 and 36030 have larger webs than the other specimens, and their snouts seem a little shorter. The dorsolateral ridge flares out somewhat in Nos. 35934, 36007 and 36008. 94 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th See. 32728 to 32733. 32734 to 32747. 35934. 36004 to 36008. 36028 to 36030.

Its flattened lumen (fig. 14-C) is much more spaci- ous and its walls correspondingly thinner than those of the true prostate. The columnar cells (fig. 19) which line the cavity have small nuclei surrounded by large vacuoles which restrict the cytoplasm to very thin trabeculae ; often the luminal ends of several cells support a large bubble of transparent secretion. Unlike the vacuolate cells of the albumen gland (fig. 21), these on the male side are but slightly stained in the serial sections. Like most parts of the reproductive system, the outside of the organ is covered with a very thin layer of pigmented cells ; these give the surface of this glandular sac an areolate ap- pearance. The second or true prostate is roughly tongue-shaped and lies (P, fig. 3) just anterior to the oviducal bulb. It consists of an enlargement of the seminal duct, lined by ciliated, cuboid epithelium, and surrounded by closely-packed, radiating, tubu- lar glands (fig. 14-D). Each of these secretory pouches is made up of large rounded cells with their long axes parallel to that of its very small central lumen, so that a transverse sec- tion of a tubule shows five or six at one time. The nucleus of each cell (fig. 17) is on the side opposite the lumen of its pouch and the cytoplasm is crowded with rather large, quite dense globules. The structure of this prostate must be quite similar to that of Lymncua ovata, although the published figures'^ do not show the lumina of the tubules or the cell boundaries. "Klotz; 1899, figs, ii-12. Vol. XIV] BAKER— ANATOMY OF LA!^X I57 Below the prostate, the first free portion of the vas deferens is rather stout and quite long; it is coiled near the right side of the haemocoele, mainly anteriad to the oviduct and bursal stalk. The imbedded section is somewhat narrower and scarcely convoluted ; it passes out through the muscle-gap and runs along the outside of the columellar muscle-ring (I, fig, 11) from the base of the oviduct to that of the penis. The second free portion extends in a tortuous course through the h?emocoele (H. fig. 3) over to the left side of the body and back again to enter at the apex of the penis; although narrower than the first free portion, the greater part of its length is quite stout and thick-walled. The last few millimeters, which are mainly coiled around the penis and under the anterior pallial nerve, are considerably narrowed, so that their con- voluted lumen is visible through the walls. The entire vas deferens is lined by a single layer of ciliated, cuboid epithelium. Outside of this is a thick envelope of circular muscle, usually with two groups of longitudinal fibers on opposite sides but rather close to the epithelial lining. I am unable to detect any gland cells outside of the epithelium ; those figured from the vas deferens of Lyinncua ovata^^ look very much like cross- sections of longitudinal muscle but they are represented as much larger than the circular fibers in the same figure. The entire male copulatory organ, termed here the penis, is very similar to that of LymncEa^'^ ; that is, it consists of an elong-ate-ovoid, preputial portion (penis-sac) and a somewhat constricted hyper phallus (penis, F. C. Baker) with a faint ter- minal knob. The hyperphallus (fig. iii-15) or capsule of the verge is not sharply demarcated externally from the remainder of the penis and is about ^ the total length of the organ. Its walls are rather thin and contain numerous sinuses which give them somewhat the appearance of erectile tissue. The hyperphallar lumen is almost completely filled by the elongate, pointe, penial papilla or verge (glans or penis of authors), which is probably the only portion that penetrates the vagina of the female. The vas deferens, with its convoluted lumen, enters the base of the verge ; the continuation of the sperm canal, which extends to the very tip, is quite narrow and cir- 'SRlotz; 1889, fig. ii-14.

The larger sac of the penis has rather thick, solid, muscular walls, which internally develop trans- verse plications and two large pilasters (fig. 14-E), that cer- tainly resemble those of Lyuincsa auricularia^^. The penis is lined by high, columnar epithelium which extends up into the cavity of the hyperphallus. The main body of the penis receives two branched muscles on its anterior side and three on its posterior. A slip (cut in fig. 14) from the upper of the anterior two, is attached to the apex of the hyperphallus so that, in my retracted specimens, this structure is bent back on the anterior side of the larger sac of the penis. The posterior muscles extend to the base of the thickened column of muscle behind the gap in the columellar ring. This origin of the hyperphallar retractor from an anterior muscle appears to be quite different from the arrangement in LymncBa^^, but it must be remembered that, in Lanx alta, all of these muscle bands arise from some part of the columellar muscle-ring. Otherwise, the genitalia are so similar to those of Lymiicea that they might almost pass for those of a species of that genus, although the enormous size of the ovotestis and the seminal reservoirs would appear to be rather distinctive. On account of the stiffness of the organs, which prevent their safe manipulation without rupture, the study of the nervous system from my material is especially difficult. The general arrangement appears quite similar to that of Lymncsa sfagnalis and L. pcregra-^ and to that of L. reHexa^', but the ganglionic ring is concentrated along the long axis of the body and stretched transversely to the right (fig. 16). This dextral distortion, which especially affects the visceral-abdominal com- plex, has already been correlated with the posterior position of the common pulmonary and anal opening. The cerebral commissure is rather long. Each cerebral ganglion is roughly triangular, with enlargements (lobes) at each corner. The nerves from the left one are: acoustic, "Klotz; 1889, figs, ii-15, 16. J»Hugo Eisig; 1869, Zeitschr. Wiss. Zool. XIX, figs, xxv-8, 9. "T. C. Baker; 1911, pi. x-xv. " Lacaze-Duthiers; 1872, Arch.

In addition, the right one gives off the penial and hyperphallar (H) ; these can be separated almost to their bases and appear to branch off just below a special, ridge-like enlargement of the gang- lion. The cerebrobuccal connectives are rather long, but loop transversely so that the buccal ganglia are quite close to the cerebral (moved away in my figure). These buccal or stoma- togastric ganglia are relatively large and give off at least the radular (R), deep pharyngeal, lateral pharyngeal and an- terior pharyngeal branches; the last sends a twig (S) to the salivary glands along their ducts. The cerebropleural connectives are very short so that the pleural ganglia are closely approximated to the cerebral. The left pleurovisceral connective is relatively long but the right visceral and pleural ganglia are in close juxtaposition. Each visceral ganglion gives off an anterior (M) and a posterior (P) pallial nerve; those of the right side are larger. The left visceral is closely united to the abdominal ganglion, although a distinct, stout connective is present between the latter and the right visceral. The abdominal ganglion gives off the sub- intestinal (G; genital), the aortic (A; anal), a root to the right anterior pallial, and one or two minute nerves to the body wall. The cerebropedal and pleuropedal connectives are short and stout, but the pedal commissure is a little longer. The pedal ganglia are large and not greatly affected by the dextral dis- tortion of the abdominal complex. Each gives off six sizable branches: superior (K) and inferior (I) cervicals, superior (D, anterior), central (E) and inferior (F, posterior) pedals and a columellar (U). The otocysts are near the anterior ends of the dorsal surfaces of the pedal ganglia. The general shape and buried position of the eyes is quite similar to that in Lymncua stagnalis^^, but a large sinus sur- rounds the outer half of each; it forms a rather large cavity between the thin corneal epithelium and the inconspicuous layer of connective tissue which underlies the thickened epidermis. »Simroth; 1876, Zeitschr. Wiss. Zool. XXVI, fig. xv-12. i^Q CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. This sinus is so large and the overlying epidemiis and sub- dermis so opaque (in preserved specimens) that a small, rounded boss is the only superficial indication of the position of each eye. The lens is large and the pigmented layer very thick, especially at its inner end, but the outer fibrillar processes of the retinal cells are poorly developed except in a little cup directly behind the center of the lens. The optic nerve is quite widely separated from the tentacular one. In the posterior portion of each tentacle, the transverse sec- tions show the presence of a small, sensory pocket, with a groove which runs posteriad and ventrad from it. On the ventral side of this pocket is a mass of ganglionic tissue. The retracted condition of my specimens prevent the accurate de- scription of the shape of this structure, as the deep folds of the tentacle obscure its position. Mucous glands, similar to those in the foot, are present in and around the base of the tentacles. My failure to find a definitely localized osphradium or organ of Lacaze-Duthiers has already been reported. These anatomical data all substantiate Dr. Pilsbry's dem- onstration that Lanx is a derivative of the Lymn^eidse and is not closely related to the Ancylidse. As Dr. Pilsbry has often pointed out, the terrestrial pulmonates appear to have a con- stantly recurrent tendency to produce slug-like forms. A sim- ilar propensity in the Basommatophora seems to lead towards ancyliform shells and bodies. In the Lancidse, specialization of the other organs has not gone so far as in the Ancylid deriv- atives of the Planorbidse; in fact, it is very remarkable that Lanx combines such profound changes of external form with such trifling divergencies in the internal anatomy, especially in that of the genital and digestive systems. On the basis of much of the anatomy, Lanx could scarcely be separated from the Lymnaeidae, but its peculiar modification of the pallial complex appears to be sufficient grounds for the retention of the Lancidje as a distinct family, with the follow- ing definitive cliaracters : 1. The limpet-like shell and the reduction of the visceral mass, especially at the expense of the digestive glands. 2, The almost complete ring of columellar muscle.

In the two tables of species of the North American Scellus published since 1907 the first couplet reads about as follows: Third joint of antenna very long and pointed virago Aldrich Third antennal joint very short 2 Below two more species are described with antennae formed the same as in virago, and which would pass for that species if no typical specimen of virago were at hand to compare them with. In 1915 I took a series of Scellus at Great Salt Lake, Utah, which I determined as virago, and had no doubt of the de- termination until 1923 when my brother sent me two speci- mens taken in California, which I found very distinct from those taken in Utah. In January, 1924, while at the National Museum I looked up the type of virago and found both my forms quite distinct from that species. I am redescribing virago to cover the points in which the three forms differ and giving full descriptions of the new forms. These three species differ from all our other species in having the third antennal joint very long and pointed. They have very long anal ap- pendages issuing from between the fourth and fifth abdominal Amgust 14, 1925 176 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. segments ; these I am calling the outer appendages, although I doubt whether they are morphologically the same as the outer lamellae of other Dolichopodidae.

Paratype, one male, same data. 7. Parandrena concinnula Cockerell Males from Whittier, Calif., Feb. 22, 1911, on flowers of Rhus (P. H. Timberlake). This is the first exact locality for the species. 8. Diandrena perchalybea (Viereck) Females: Carmel, California, May 19 (Van Dyke). The hair of the head and thorax above is conspicuously paler than in a specimen from Washington State, whence the species was described, but the difference cannot indicate another species. The bees, like the birds and mammals, tend to melanism north- ward in the Pacific coast region, but good series from many localities will be required before we can fully elucidate the phenomenon and clearly distinguish whatever local races may exist. This work should of course be done by a resident of one of the coast States. A male from Mokelumne Hill, California (Blaisdell), is re- ferred here, though the male of D. perchalybea has not been described, and the reference should be confirmed by field ob- servations. It is exceedingly like the males of D. nothocalaidis Ckll. and D. cyanosoma Ckll, the abdomen being duller than in the former, but more shining than in the latter. In all three Jgg CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. the face has long- white hair, black along the orbits. In D. cyanosoma the area of metathorax is finely wrinkled or sub- reticulate all over, with short transverse rugae on each side of middle line; in D. nothocalaidis it is quite different, with fewer rugae, and well separated longitudinal ones in the basal part. In the) male supposed to belong to D. perchalybea, it is sculpn tured practically as in D. nothocalaidis, but the posterior angle of the enclosure is much wider. The flagellum is much redder than in D. nothocalaidis. The metathoracic sculpture of the male differs appreciably from that of the female D. perchalybea, but the difference is similar to that in the undoubted sexes of D. nothocalaidis. 9. Nomia melanderi Cockerell Four males from Payette, Idaho, June 29, 1922 (Van Dyke), and one from Los Banos, California, May 22, 1918 (Van Duzee), have black tegulae, and no green band on first abdominal segment, and must be referred to A^. melanderi. The abdominal bands are bluish green, and the antennae and struc- ture of abdomen, etc., are as in A^. acus Cockerell, which is ap- parently to be called A^. melanderi acus, being merely a slightly modified southern race. 10. Nomia califomica Cockerell Preston, Idaho, 19 females, July 17, 1922 (Van Duzee) ; Logan, Utah, 4 females.

The area of metathorax is more like that of A. texayius subtilior Ckll., but that form is quite differently colored. From A. borealis Craw- ford, which is another segregate from A. texanus, the present form will be known by the smaller size and golden (instead of bluish) reflections. As the three specimens are alike, we doubtless have a dis- tinct subspecies or race. Type: Female, No. 1652, Mus. Calif. Acad. Sci., collected by E. C. Van Dyke, June 25, 1921, in Yosemite Valley, Cali- fornia. Paratypes, two females, same place, July 1, 1921. 19. Sphecodes arvensiformis Cockerell Males: Lagoon, Utah, June 30 (Van Duzee) ; Sobre Vista, Sonoma County, California, May 12 (J. A. Kusche). 5. arvensiformis was described from the female. These entirely black males are referred to it on the basis of probabilities, but the reference should be confirmed by biological observations. 192 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. They very closely resemble the male of S. arvensis Patton, but are distinctly larger, with darker wings, and more robust flagellum. The Utah form differs from that of California by the uniformly dusky wings, those of the latter being pale, with the apical margin broadly dusky. In the California specimen the first recurrent nervure meets the second intercubitus ; but one Utah specimen has the second cubital cell rather broad, with the recurrent nervure near its end, while the other has the cell narrow, and the recurrent near the middle. I extracted the genitalia from the California specimen and the Utah one with broad second cubital, and do not see any material difference. Females of ^. arvensiformis have the second cubital narrow. As matters stand at present, it appears necessary to refer these black males to 5*. arvensiformis, but future work may prove the existence of more than one species of this alliance in the region concerned. 20. Perdita pyrifera Cockerell, new species Female : Length about 5.5 mm. ; head and thorax green, the meso- thorax shining yellowish green, and very sparsely punctured ; wings remarkably short, strongly dusky, stigma and nervures sepia brown ; abdomen flattened, dullish, entirely light yellowish ferruginous except a pair of suffused black spots on first segment, and a black line at each extreme side of second ; the second and third segments may show suffused and faint traces of transverse yellowish bands ; head ordinary, facial quadrangle longer than broad ; no supraclypeal or dog-ear marks ; clypeus shining black, sparsely punctured, with a very slender median pale line (sometimes reduced to a dot) on upper part; labrum black, prominent, concave in middle ; mandibles light yellow, black at end ; lateral face marks large, very pale yellow, pear-shaped, the very acute upper end on orbit at about level of antennae; flagellum pale yellowish beneath; front dull ; cheeks unarmed ; tubercles and two marks on upper border of pro- thorax light yellow; pleura shining; tegulse dark in front, very pale be- hind ; second cubital cell very large, greatly narrowed above ; anterior and middle femora robust ; legs black, or very dark brown ; anterior and middle knees, and broad stripe down their tibiae in front, pale yellow. Runs in my table next to the much smaller and quite differ- ent P. chamcEsarachcc Ckll. Superficially, it resembles P. rufi- cauda Ckll., but is easily separated by the jX)lished mesothorax, and first recurrent nervure joining second cubital cell a short distance from base, instead of meeting tlie intercubitus.

Perdita claypolei Cockerell Female: Mt. San Antonio, California, 5000 ft., at flowers of Eriogonum fasciciilatum, August 22 (Timberlake). The head and thorax are yellowish green instead of blue-green as they are in a cotype from Mt. Lowe. 22. Perdita exclamans imperialis Cockerell, new subspecies Female: Lateral face-marks linear above, not reaching level of ocelli; bands on abdominal segments narrower, those on second and third like those on fourth and fifth. The hind margin even except for a broad median notch, and the obhque extensions at extreme sides to edge of abdomen ; yellow mark on lower part of cheeks reduced to a small spot. Type: Female, No. 1654, Mus. Calif. Acad. Sci., collected by E. P. Van Duzee, April 8, 1923, at Potholes, Imperial Co., California, on mesquite. Typical exclamans Ckll. also visits mesquite. 23. Perdita cleomellae Cockerell, new species Female (type): Length about 4 mm.; head and thorax shining dark green, with white or cream-colored markings, the mesothorax and scutel- lum very highly polished ; head ordinary, cheeks unarmed ; labial palpi with last three joints together shorter than first; labrum, mandibles (ex- cept apically), clypeus, quadrate supraclypeal mark; and lateral marks forming broad bands ending obliquely at level of antennae, white; cheeks dark, with white hair ; no dog-ear marks ; scape creamy-white ; flagellum dark, pallid beneath, and the tip pallid above ; collar and tubercles cream- color ; tegulse hyaline with a white spot ; wings clear hyaline, stigma and marginal cell margined with brown ; first four legs and hind femora cream color, hind tibias and tarsi blackish, the tibiae pale at base ; abdomen cream-color with four entire black bands ; apical plate red ; venter en- tirely pale. Male : Length a little over 3 mm. ; face polished, entirely creamy-white below antennae, the lateral marks extending some distance up sides of front, ending very obliquely ; flagellum light brown above, pale yellow below ; hind tibiae pale yellow ; abdomen with five bands, but they are more or less brown, especially the last two. August 14, 1925 J94 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Both sexes at flowers of Cleomella obtusifolia; Barstow, California, September 12, 1924 (P. H. Timberlake). Numer- ous specimens were taken on the flowers. The female comes close to P. interserta Ckll., from Los Angeles County, Cali- fornia, but is easily separated by the small size and white mark- ings. There is also some resemblance to the much larger P. townsendi Ckll. The male shows some resemblance to P. ex- damans atramentata Ckll, from Sonora. Two paratypes have been deposited in the collection of the California Academy of Sciences. 24. Perdita timberlakei Cockerell, new species Female (type) : Length slightly over 4 mm. ; head and thorax shin- ing dark blue-green, yellowish green or mesothorax ; head small, without light markings, but mandibles ferruginous beyond base, scape pale yellow in front, flagellum dusky reddish beneath; upper border of prothorax and tubercles pale yellow ; tegulae hyaline, with a yellow spot ; wings hyaline, stigma and marginal cell dusky-margined ; legs black, with the anterior tibix very broadly light lemon-yellow in front, their tarsi pale reddish ; middle tibiae with a yellow stripe ; abdomen black, with four lemon- yellow bands, only the first reaching the lateral margins ; first segment yellow at base, and this connected with a large discal more or less tri- lobed yellow spot ; venter brown. Male : Length about 3 mm. ; face below antennae, labrum and mandi- bles, clear white, the lateral marks extending to a point about half way up front ; scape robust, light yellow in front ; flagellum light yellow be- neath ; yellow on upper border of prothorax reduced to a spot at each corner; anterior and middle femora yellow beneath; first four tibiae yellow, hind tibiae yellow in front; abdomen dark brown, with yellow bands at bases of second and third segments, and vestiges of one on fourth. At flowers of an annual Eriogonum, Riverside, California, September 24, 1924 (P. H. Timberlake). Runs in the tables near to P. subfasciata Ckll. and P. punctifera Ckll., but is quite distinct. It is not at all allied to P. ftorissantella Ckll., which visits Eriogonum in Colorado. Two paratypes have been de- posited in the collection of the California Academy of Sciences. 25. Perdita vittata Cockerell Two females, La Paz, June 29 (Ferris). Vol. XIV] COCKERELL—BEES 195 26. Spinoliella peninsularis Cockerell Very many specimens, both sexes, La Paz, June 29 (Ferris). 27. Spinoliella edwardsii (Cresson) Male and female: Huntington Lake, California, 7000 ft., July 10 (Van Duzee). The female is of the form lateralis (Cresson) ; male, Fallen Leaf Lake, Lake Tahoe, July (L. S. Rosenbaum) , 28. Spinoliella scutellaris (Fowler) Both sexes; Salt Lake City, Utah, June 25 (Van Duzee) ; male. Lagoon, Utah, June 30 (Van Duzee) ; females, Logan, Utah, July 18, and Saltair, July 12 (Van Duzee). The male is easily known by the abruptly dark apical part of the antennae. The female was described by Fowler as Calliopsis visaliensis. The type of 5. scutellaris was taken by Woodworth at Fresno, that of visaliensis by the same collector at Visalia, both on May 9. It is now clear that 6', scutellaris peninsularis Ckll. is a dis- tinct species, Spinoliella peninsularis. The male, collected by Ferris at La Paz, June 29, has the flagellum white beneath to the end. 29. Spinoliella anthidius (Fowler) Male : Bear Valley, San Bernardino Mts., California, July (F. C. Clark). Fowler's description is of the male, not female as he has it. The abdominal bands, broadly interrupted sub- laterally, are very distinctive. This species has previously been known only from Fowler's type, collected by Woodworth at Tulare. 30. Spinoliella triangulifera Cockerell, new species Female: Length slightly over 7 mm.; black, with cream-colored sub- equilateral triangular marks at lower corners of face, and large cream- colored spots at sides of first four abdominal segments, those on first two rounded, on the others transverse, pointed mesad ; hair of head and thorax j^^ CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. quite long and abundant, grey, more brownish dorsally ; clypeus shining, with irregular strong punctures, and a very inconspicuous median pale line, not extending more than half way down ; flagellum obscurely reddish beneath ; mesothorax highly polished, very sparsely punctured ; tegulse black ; wings strongly greyish ; stigma and nervures dark brown ; abdomen broad, shining. Type: Female, No. 1655, Mus. Calif. Acad. Sci., collected by E. C. Van Dyke, July 1, 1921, at Yosemite Valley, Cali- fornia. Closely allied to S. edivardsii yar, lateralis (Cress.), but smaller, the wings not so strongly reddened, more greyish, and the scutellum not excavated or depressed in middle. It is also related to S. ohscurella (Cress.), but that species is larger, with flagellum bright ferruginous beneath, and continuous bands on abdomen. 31. Spinoliella equina Cockerell, new species Female (type) : Length nearly 7 mm.; black, with cream-colored mark- ings; hair of head and thorax dull whitish, dorsally becoming brownish; eyes green; mandibles whitish at base, then red, apically black; labrum black; clypeus light, with a large black horse-shoe shaped mark (the arms ending on upper margin), from which there is a small projection on each side, or rarely the middle of clypeus is entirely black, except a small pale spot ; superaclypeal and dog-ear marks present ; lateral face marks very broad triangles with base on orbit, the upper point acute, level with an- tennje; flagellum rather dull red beneath, except at base; mesothorax shin- ing, sparsely punctured ; post-scutellum and obscure spot on tubercles cream-color ; tegulae piceous ; wings hyaline, very faintly dusky ; stigma slender, very pale reddish, nervures brown ; anterior and middle knees, and anterior tibiae in front, pale yellow; anterior tarsi red; abdomen with cream-colored bands, interrupted on first two segments (very broadly on second), notched or slightly interrupted on third, entire on fourth; all these bands excavated sublaterally behind. Male : Described by Swenk and Cockerell as the male of 6". Iicsperia, but evidently belonging to the present species. 5". hesperia Swenk & Ckll. must be restricted to the form described from the female, which has bright yellow markings. The female resembles S. anstralior Ckll., but that species lacks the dog-ear marks (at each side of supraclypeal mark), and has the postscutellum black. The face-marks of female vS". equina resemble those of the much larger S. sehrata (Cress). Vol. XIV] COCKERELL—BEES \^'J Type: Female, No. 1656, Mus. Calif. Acad. Sci., collected by E. P.

Calliopsis pugionis Cockerell, new species Female : Length a little over 7.5 mm. ; black, with the anterior and middle knees shining yellow, an interrupted yellow band on upper margin of prothorax (but tubercles black), and lemon-yellow markings on face, as follows: triangular supraclypeal mark (highly polished and im- punctate), lateral corners of clypeus broadly, and upper and lateral mar- gins narrowly, with a dagger-shaped median line from the upper margin, hardly reaching half way to apex, and very broad lateral face-marks, separated from clypeus at upper part, and ending acutely on orbital margin above level of antennae; face very broad; eyes deep green; mandi- bles red in middle ; flagellum bright ferruginous beneath ; hair of head and thorax largely white, but dorsally pale fulvous, short on thorax above ; mesothorax closely punctured; base of metathorax highly polished; tegulae dark brown ; wings brownish, stigma and nervures brown ; abdomen shin- ing, with four white hair-bands, that on first segment broadly interrupted in middle; hind margins of segments rufescent; ventral segments with transverse depressions, deep on second. jQg CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Nearest to E. coloradensis Cresson, but easily separated by the color of the face-marks. Type: Female, No. 1657, Mus. Calif. Acad. Sci., collected by E. P. Van Duzee, June 3, 1917, at Soboba Springs, River- side Co., California. 33. Panurginus atriceps (Cresson) Male: Carmel, Monterey County, California, March 25 (Van Duzee). Known by the entirely black face of the male, and the first recurrent nervure meeting first intercubitus, or even falling basad of it. It is related rather to P. albopilosus (Lucas), of Spain and Algeria, than to the other N. American species. Females: Portland, Oregon, July 3 (W. M. Giffard). 34. Hesperapis pellucidus Cockerell, new species Male : Length about 7 mm. ; black, with abundant pure white hair ; runs in my table and Crawford's to H. larrea Ckll., which it very closely resembles, having the same size and appearance, clear wings, and long white hair covering clypeus. It differs thus : flagellum black, with at most a very obscure reddish tint beneath ; mesothorax more distinctly punc- tured ; extreme base of metathoracic area dull and granular ; first recur- rent nervure nearer base of second cubital cell, and much nearer to base than second to apex ; basal nervure not so remote from nervulus ; hind margins of abdominal segments with broad dense pure white bands of tomentum. The insect has the aspect of a small Colletes. Numerous males from San Francisco, California, April 20- June 6 (E. P. Van Duzee and F. E. Blaisdell). There is a rather close general resemblance to H. leucura Ckll., from Lower California. Type: Male, No. 1658, Mus. Calif. Acad. Sci., collected by E. P.

Halictoides davidsoni Cockerell Many males from Huntington Lake, Fresno County, Cali- fornia, 7000 ft., July 4 to 28 (E. P. Van Duzee and F. C. Clark), and one from Cascada, Fresno County, 6000 ft., July 29 (Van Duzee). There are also two females from Hunting- ton Lake, July 8 (Van Duzee). The female runs in my table (Entom. News, 1916, p. 62) to the same place as H. mulleri Ckll., but is readily known from that species by the absence of the broad bands of dull white tomentum at bases of abdominal segments, though there is a very slender band at base of fourth segment, only visible when the segment is much exserted. Other features are the greenish, highly polished and strongly punctured mesothorax, the long, black hair on clypeus, and the flagellum only very obscurely reddish beneath. 36. Halictoides (Cryptohalictoides) spiniferus (Viereck) Males from Huntington Lake, Fresno County, California, July 9 to 28 (E. P. Van Duzee and F. C. Clark).

One male is from sunflower. 44. Triepeolus pacis Cockerell, new species Male: Length about 8.3 mm.; black, with the ornaments of head and thorax above very pale ochreous, of pleura, coxae and face (which is densely covered with hair), white; scape black, very obscurely reddish at apex ; flagellum bright ferruginous at extreme base (with a black mark on inner side), otherwise black; eyes dark grey; tegulae bright ferrugi- nous ; wings dusky hyaline, nervures and stigma piceous ; legs bright ferruginous, hind tibise suffused with dusky on outer side, but there cov- ered with appressed white hair; hair on inner side of hind basitarsi light orange ; hind spurs black or nearly so ; apical plate of abdomen dark brown, long and nearly parallel-sided. Labrum dusky in middle, ferrugi- nous at sides ; mandibles red in middle ; mesothorax with a pair of rather short stripes, reaching anterior margin, but not connected with marginal band, which only goes to anterior corners; scutellum strongly bigibbous ; axillae prominent ; upper part of mesopleura with a broad transverse band of dense white hair, below this the surface is thinly hairy, the very dense punctures with shining margins visible ; abdominal bands even and entire, except that the light hair at base of first segment is interrupted ; black area on first segment a very broad band, ending very obliquely at sides ; lateral corners of black on second segment rounded, not sharply acute; venter with much pure white hair, the outstanding fringe pale yellowish. 202 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Related to T. blaisdelli Ckll. & Sandh., to which it runs in my recent table, but easily separated by the dark scape and flaggellum, the area of metathorax bare except at sides, the larger and darker stigma, etc. From T. mensce Ckll. it is easily known by the color of flagellum, etc. The transverse band on first abdominal segment is much broader than in T. norco Ckll.

Oreopasites vanduzeei, Cockerell, new species Female : Length a little over 5 mm., with broad convex abdomen ; head and thorax black, with white hair, shining silvery on face, sides of thorax and metathorax, thin on thorax above, not hiding surface ; ab- domen entirely clear ferruginous, with thin pure white hair-bands more or less developed at sides of segments; legs ferruginous, with the an- terior femora darkened above, and the hind spurs dark ; labrum, mandi- bles and lower edge of clypeus dusky red, the labrum elongated, broadly rounded at end ; antennae ferruginous beneath ; tegulae dusky red ; wings hyaline, faintly dusky. I have not ventured to extract the mouth parts from the unique specimen, but they are extruded, and the labial palpi measure about as follows in microns: first joint 575, second 350, third and fourth each 50; the maxillary palpi clearly show five joints. I can- not demonstrate the basal tubercle-like joint which should be present. The marginal cell is considerably shorter than in O. scituli Ckll., and the mesothorax is strongly and densely punctured. The basal portions of the abdominal tergites are finely and densely punctured. The only species previously known, 0. scituli^ was found to be parasitic on Spinoliella in Colorado. The new species was taken at the same locality, on the same day, as a quantity of Spinoliella equina, and with little doubt is parasitic in the nests of that bee. Type: Female, No. 1662, Mus. Calif. Acad. Sci., collected by E. P. Van Duzee, August 21, 1919, at Stockton, California. 46. Exomalopsis pulchella arida Cockerell A very long series, including both sexes, indicates that what 1 recorded as E. siniilis is, as I then suspected, only a variety of pulchella. Both pulchella and siniilis were described from Cuba, and presumably represent the variation of the species in Vol. XIV] COCKERELL—BEES 203 that island. The form from Lower California appears to be a distinct race for which the above name is available. Most of the sj?€cimens in the series now before me distinctly belong to arida as originally defined, but some have the hair of hind tarsi pale ferruginous, lacking the blackish or grayish color. La Paz, June 29 (Ferris), 47. Exomalopsis (Anthophorula) chionura Cockerell, new species Female (type) : Similar to E. chlorina Ckll. (from New Mexico), but eyes not or not distinctly green ; stigma dark brown ; mesothorax polished, without evident punctures (distinctly punctured in chlorina) ; white bands on second and third abdominal segments broader laterally. It is also very close to E. texana Friese, differing by the dark tegulae (clear red in texana), dark stigma (pale amber in texana) and pure white (instead of creamy) hair on abdomen. Male : Similar in most respects, but with narrower face ; the clypcus (except two spots), labrum and basal part of mandibles pale yellow; flagellum long, dull ferruginous beneath. Compared with the male of E. coquilletti (Ashmead), it is readily separated by the shorter flagellum, and pure white hair on abdomen. The male of E. chlorina is unknown. I hesitated whether to call this a distinct species, or a race of E. chlorina, but it seems best to regard it as a species, on account of the difference in the sculpture of the mesothorax. Presumably the closely related species of this group have dif- ferent flower-visiting habits. E. chlorina is known to visit Sphacralcea (Malvaceae). Type: Female, No. 1663, Mus. Calif. Acad.

Chelostomopsis Cockerell, new genus Small bees allied to Chelostoma, but labial palpi four jointed, with two outstanding small joints; maxillary palpi three-jointed; lower margin of clypeus v/ith a long median process, obtuse or truncate at end, parallel- sided ; basin of first abdominal segment rather small, with a distinct rim; first recurrent nervure joining second cubital cell some distance beyond base. Type Chelostomopsis rubifloris (Chelynia rubifloris Cockerell). True Chelostoma has only one outstanding small joint to labial palpi. This is also true of the subgenus Gyrodroma Thomson, type nigriconiis Nylander. I designate nigricornis as the type of Gyrodroma. because of the confusion concerning 206 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Thomson's other species, which he called florisomnis, whereas it was really campanularum. Formicapis of Sladen has a process on clypeus, but it is broad-conical, and the position of the first recurrent nervure is quite different. The marginal cell of Formicapis is more nar- rowed apically. In addition to the type species, the new genus includes Chelostomopsis australis (Chclostoma australis Cockerell). Only the female is known. 55. Chelostomopsis rubifloris edwardsii (Cockerell) Female: Yorkville, Mendocino County, California, May 1 (Van Duzee). Typical C. rubifloris is from Seattle. 56. Chelostomopsis australis nanus Cockerell, new subspecies Female: Length 6.5-7 mm. (typical australis about 9 mm.); wings distinctly dusky; area of metathorax polished and shining; red on second abdominal segment greatly reduced or wanting. The type of C. australis was from near Los Angeles; the present form seems to be only a subspecies. The first recurrent nervure is much more remote from the base of second cubital cell than the second from apex of that cell. This is not the case with Cephalapis jacintana, which might perhaps be con- fused with it on account of the red at sides of base of abdomen. Type: Female, No. 1666, Mus. Calif. Acad. Sci., collected by F. C. Clark, August, 1913, in Bear Valley, San Bernardino Co., California. Paratype, one female, same data. 57. Cephalapis jacintana (Cockerell) Male: Bryson, California, May 18 (E. P. Van Duzee). 58. Ashmeadiella howardi Cockerell Male: Bryson, Monterey County, California, May 18 (Van Duzee). Vol. XIV] COCKERELL—BEES 2ff7 59. Ashmeadiella crassa Cockerell Female: Mokelumne Hill, California, September 6 (Blais- dell). This is a larger, robust form, which may prove separ- able when the male is known. I have found quite parallel supposed variation in A. meliloti Ckll., but here also I am not without misgivings concerning the specific identity of the large and small forms. 60. Chelynia rubi (Cockerell) Melanostelis betheli Ashmead is a synonym; Melanostelis may be regarded as a subgenus. Both sexes from Fallen Leaf Lake, California, June 26-July 26 (Van Dyke) ; Yosemite Valley, California, male May 15, female June 23 (Van Dyke) ; female, Meadow Valley, Plumas County, 3500-4000 ft., June 1 (Van Dyke). The original type female, from Seattle, has the light bands on first two abdominal segments very narrowly in- terrupted; they are not at all interrupted in the Californian specimens. The male is only 6 to 7 mm. long, and has pure white hair on face, and much white hair on thorax; hair of pleura clear white. 6L Chelynia franciscana Cockerell, new species Female : Length about 8 mm. ; head and thorax green, abdomen blue- green, almost a peacock blue, the hind margins of the segments not purple; pubescence black; scape metallic; flagellum black, very faintly reddish beneath ; mesothorax yellowish-green, shining, with coarse punctures ; pleura blue-green, densely punctured; base of metathorax rugose; tegulse green ; wings strongly dusky ; legs blue-green ; middle tibiae bidentate at end; abdomen polished, brilliant, the depressed hind margins of the seg- ments much more finely and closely punctured than the part before ; apical tergite not modified. Allied to C. pavonina Ckll., but readily separated by the polished abdomen, with the hind margins of the segments not purple. 208 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser.

Close to C. pavonina Ckll., and perhaps only a variety or race, distinguished by the color of the thorax. C. pavonina occurs in Colorado. Type: Female, No. 1668, Mus. Calif. Acad. Sci., collected by F. E. Blaisdell, in April, at Mokelumne Hill, California. 63. Chelynia leucctricha Cockerell, new species Female (type) : Length 7.5 to 9 mm.; head, thorax, abdomen and legs brilliant blue, suffused with greenish on clypeus, middle of front, and mesothorax ; hair of head and thorax clear white, with black hairs sparsely intermixed, the white hair of face conspicuous; clypeus dull; scape blue, flagellum very obscurely brownish beneath ; mesothorax with very large punctures, but shining between the punctures, which are not very dense on disc; scutellum shining, with large punctures; tegulse blue- green ; wings dilute fuliginous ; abdomen shining but roughened, the hind margin of the first segment brilliant purple, of the others decreasingly purplish ; hind margins of ventral segments appearing white in lateral view.

Chelynia nitidula Cockerell, new species Male : Length about 6.5 mm. ; rich deep blue, with cream-colored bands on first four abdominal segments, and a pair of transverse marks close together on fifth ; the band on first segment is constricted in middle, the others narrowly interrupted, and all are very shallowly excavated poster- iorly on each side; hair of head and thorax white, mixed with black, en- tirely black on mesopleura; flagellum black; disc of mesothorax shining, with well separated punctures; area of metathorax shining; tegulse very dark, submetallic ; wings dilute fuliginous ; abdomen shining. There is long black hair on the scutellum. Related to C. subccentlca (Cress.) and C. pulchra (Craw- ford). From the former it is separated by the small size and large amount of white hair on thorax above, as well as the rich blue color. It is much smaller than C. pulchra, which occurs in the Rocky Mountain Region. Type: Male, No. 1672, Mus. Calif. Acad. Sci., collected by E. P.

Subsequent work may show that some of these represent varieties or races rather than species, but at present no inter- mediates are known. 68. Stelis laticincta Cresson Cascada, Fresno County, California, 6000 ft., July 29, 1 male, 1 female (Van Duzee) ; Cazadero, September 2, male (Van Duzee); Stockton, August 21, male (Van Duzee). Cresson described the female; I described the male in 1904. The species is very variable in the male, in the width of the bands along anterior orbits, the amount of yellow on the pleura, and the presence or absence of yellow on the sixth ab- dominal tergite. It seems probable that there are two or three separable races, but more material is needed to demonstrate this. Mr. W. M. Giffard collected in Santa Clara County, Cali- fornia, July 16, a female S. laticincta agreeing with Cresson's description in having the clypeus black with a yellow spot on 212 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. each side. A female from Cazadero, California, has the clypeus yellow with the upper margin broadly black. 69. Stelis sexmaculata Ashmead Male: Blue Lakes, Lake County, California, May 16 (Van Duzee). The specimen has eight spots on the abdomen, as is frequently the case. 70. Stelis carnifex Cockerell Female: S. Sonoma County, California, June 26 (Kusche) ; compared with the cotype from Nevada, the face is wider and the head more densely punctured. Male : Phillips Station, Placer County, California, July 24 (Blaisdell). This species, as now understood, appears to be very variable. Additional material may show that it should be divided. 71.

DALLAS HANNA Cifrafor, Department of Paleontology Introduction At the Berkeley meeting of the Pacific Division of the American Association for the Advancement of Science in 1921 there was appointed a "Committee on the Conservation of Marine Life of the Pacific," Dr. Barton Warren Evermann, Chairman.^ The first task which the Committee undertook ' The full membership of the committee was as follows when the expedition was organized: Dr. Barton Warren Evermann, Chair- man, California Academy of Sciences, San Francisco, Calif.

September 5, 1925 2jg CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. was the making of recommendations to the proper authorities for the conservation of certain of the marine mammals of that ocean. In the case of a few species, such as the Alaska fur seal, there existed sufficient authoritative information in gov- ernmental reports to enable the advocation of certain measures which, it was believed, would aid materially in bringing them back to their former abundance and commercial importance. But with other species practically nothing was known of their present status or condition ; indeed, the very existence of some of them was in doubt. The Committee at once proceeded to devise means whereby this deficiency could be filled in order that definite facts might be available for it to use in urging measures of protection. This absence of late information was notably true in respect to the Guadalupe elephant seal, Guada- lupe fur seal and southern sea otter, all of which once existed in great abundance along the shores of California and Lower California. The latest data in respect to them had been secured many years ago and was not sufficiently recent, it appeared, to warrant an active campaign for the preservation of the species. Therefore, through the activities of the Committee, an expe- dition was dispatched from San Diego, California, on July 9, 1922, to the islands off the west coast of Lower California for the primary purpose of securing information in regard to the three above-mentioned species of sea mammals. The fol- lowing institutions actively cooperated in the enterprise : National Government of Mexico, California Academy of Sciences, San Diego Society of Natural History, Scripps Institution for Biological Research, National Geographic Society. The Government of Mexico provided the Fisheries Patrol Boat Tccate for the work and met all expenses while the party was in the field ; and that country was represented by the fol- lowing official personnel : Professor Carlos Cuesta-Terron, Curator of Fishes and Reptiles of the National Museum of Mexico, in charge of the expedition ; Professor Jose M. Gal- legos. Explorer of the National Museum of Mexico; Sr. Vol. XIV] HANN A— EXPEDITION TO GUADALUPE ISLAND 219 Joaquin Palacios, Inspector of Lighthouses ; Sr. Rudolpho Lascano, Assistant Inspector of Lighthouses ; Sr. Enrique Gonzales. Insi)ector of Fisheries ; and Sr. Luis Rubio, Taxi- dermist. The Committee was represented by the writer (Secretary) and Mr. A. W. Anthony. They also represented the California Academy of Sciences and the San Diego Society of Natural History, respectively, and were placed in charge of the scien- tific work of the expedition. Advantage was taken of this exceptional opportunity to secure scientific data in other branches of natural history in this little know'n and seldom visited region. Mr. Joseph R. Slevin, Assistant Curator, De- partment of Herpetology, and Mr. Frank Tose, Chief Taxi- dermist, accompanied the expedition from the California Acad- emy of Sciences. Mr. Ernest Hinkley went from the San Diego Society of Natural History. The Scripps Institution for Biological Research, being actively engaged in oceanographic studies of broad scope, sent Mr. P. S. Barnhart for the sys- tematic collection of water and plankton samples and ocean temperatures. The motor ship Tecate was admirably suited to the work in hand and the success of the expedition was in no small measure due to the constant interest of Captain Victor Angxilo and his w^ll trained crew. Everything possible was done to aid the observers and collectors during the five weeks in the field. (See pi. 15, fig. 1.) The expedition returned to San Diego on August 16 after having visited the following desert islands : Guadalupe, San Martin, Cedros, the three San Benitos, Natividad, San Roque, Asuncion, Magdalena, and Santa Margarita. Landings were also made at Ensenada, San Quintin Bay, San Bartolome Bay and Abreojos Point on the Peninsula of Lower California. Besides making observations and extensive collections of nat- ural history specimens at all of these places, the coast line was studied at close range for considerable distances from the vesel, particularly around the long bight known as San Cristobal Bay where elephant seals are known to have once hauled out on the sands in aJjundance. Also a large number of samples of September 5, 1925 220 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. animal and plant life of the open ocean (plankton) and tem- perature records were systematically collected. Specimens were obtained in the various groups in approxi- mately the following numbers: birds and mammals, 300; rep- tiles and amphibians, 1000; insects, 1100; land shells, 2000; marine fossils, many; and miscellaneous fishes, invertebrates, and plants. These have all been submitted to specialists and the technical reports upon them will be published in due time. It is already known that numerous strange and rare forms of animal life are represented in the collections, many of them being entirely new to science. Readers interested in the sub- jects are referred to these final reports for complete and techni- cal information. In the following pages an attempt has been made to give the most interesting features of these desert isles and the general results of our search for the fur seals, elephant seals and sea otters. Organization The organization of the expedition w^as largely the result of the activities of Dr. Barton Warren Evermann and Mr. A. W. Anthony, Directors of the California Academy of Sciences and the San Diego Society of Natural History, respectively. Through them the cooperation of the National Government of Mexico was obtained and the success of the undertaking was assured. It was understood informally that Sr. Ing. Ignacio Romero, Agente General de la Secretaria de Agricul- tura y Fomento, Tijuana, B. C., was an enthusiastic supporter of the enterprise from the start and aided in many ways in arranging the details necessary for the despatch of the Tecate and party. The following general memorandum was prepared before departure of the expedition and was distributed for guidance in the work proposed. "1.

Personnel. — The expedition will be made on the Fisheries Patrol Vessel Tccatc which the Alexican government has generously detailed for the purpose, and will be under the general direction and supervision of Sefior Carlos Cuesta-Terron of the National Museum of Mexico, who will have associated with him a number of scientific gentlemen of his country. [American members of the scientific staff were then listed. Seep. 217.] The scientific investigations will be under the immediate direction of Messrs. Hanna and Anthony. 3. Field of operations. — Islands and their surrounding waters off the west coast of Lower California, particularly the islands of Guadalupe, San Benito, Cedros, and Natividad ; also Magdalena Bay and other points on the mainland. 4. Purpose. — The primary purpose of the expedition is to make investi- gations to determine as fully as may be the present abundance and condi- tion of the southern fur seal, southern sea otter, and elephant seal in the localities visited. It is known that each of those three important and valuable marine mammals was at one time quite common not only about the islands men- tioned but also about the islands on the California coast as far north as the Farallons. Records believed trustworthy show that in the years 1808 to 1811, more than 203,000 fur seals were taken on the Farallon Islands, besides many thousands on the Channel Islands, Cedros and other islands ofif the coast of Lower California. Records also show that the southern sea otter was at one time very abundant in the great kelp beds about these same islands, more than 22,000 having been taken prior to 1806. The elephant seal was once abundant on Guadalupe Island and on other islands on this coast. It is generally believed that each of these interesting animals is now extinct or nearly so ; but certain recent discoveries indicate that at least small remnants of each of the three species still exist. It is the purpose of this expedition to find out the facts in-so-far as is possible and place them before the State Departments of the United States and Mexican governments in the hope that the necessary steps may be taken by the two governments through an international treaty for the adequate protection of these valuable natural resources. 5. Other scientific investigations. — The scientists of this expedition will avail themselves of the exceptional opportunities for making a gen- eral survey of the fauna and flora and geology of the islands visited. They will be equipped for making collections in various branches of nat- 222 CALIFORNIA ACADEMY OF SCIEXCES [Proc. 4Tif Ser. ural history, particularly of birds, mammals, insects, shells, botany, and fossils. These islands have been but little explored and it is believed that many new species will be discovered.

This was used for photographic purposes with the understanding that prints from all official still-camera pictures should be furnished to the Society accompanying an article suitable for publication in its magazine.^ Of 360 exposures made with a 4x5 camera, 314 negatives were obtained, suitable for illustrative purposes. Prints of these were furnished to the National Geographic Society; the San Diego Society of Natural History; the National Govern- ment of Mexico; the California Academy of Sciences; and various members of the party. The negatives have been depos- ited in the latter institution. In addition to the above, several members of the party took photographs, prints of which were furnished to the Academy. About 800 feet of motion picture negative was made of the herd of elephant seals on Guadalupe Island. This has been deposited in the Academy and prints were furnished to the National Government of Mexico and the San Diego Society of Natural History. Upon the completion of technical reports of the scientific collections obtained it was understood that an equitable division of specimens would be made among the institutions represented.

Informal talks were given by Dr. Barton Warren Evermann, Sr. Jose M. Gallegos, Dr. Fred Baker and others. Next morning, July 9, at nine the lines of the Tecatc were cast off at San Diego and Ensenada was reached at five the same day. The Mexican officials were hosts at a dinner given to the rest of us that evening. At three p. m. of the tenth the last of the stores had been taken aboard and the ship was headed toward Guadalupe Island, 170 miles to the southwest. Off Point Banda there are 10 rocks, white from the occu- pancy of them by various birds, chiefly brown pelicans, Brandt's cormorants and western gulls. Eight of these rocks were occu- pied by California sea lions, the total number being estimated * See, "Mexico and Central America Pilot (West Coast)," Hydrographic Office, U. S.

Close watch was kept for sea otters and fur seals in the kelp beds as the Tecate passed close inshore here but, as was to be expected, none was seen. Formerly both species lived at this point in great abundance and it is not so many years ago that 30 sea otters were killed ; this was the last time a large number was slaughtered. Since then the species has been practically extinct and in a region where a century and a half before thousands were killed in a single season. Before darkness closed in about the little motorship, two red phalaropes were seen feeding on the sea. They were in full fall plumage and it seems incredible that they had been to the breeding grounds in northern Alaska and had returned this far south already on the fall migration. They must surely have remained behind the great flocks which annually follow the American coast to the Arctic regions. On the 11th, at ten a. m., Mr. Slevin, with eyes trained to the sea, announced Guadalupe Island in sight. Two hours later, between banks of fog, the ruggedness of the black scorched cliffs of the north end was in plain sight and at three p. m. we landed at the place called "Northeast Anchorage." A settlement had formerly been at this place; sometimes it consisted of soldiers and their families ; again the occupants were those trying to successfully exploit the goats of the island. At this time the place was not inhabited but one of the sheds almost filled with dried meat and skins indicated that people had occupied the place not more than one or two years pre- viously. The best of the buildings was a two story adobe house used by officers of the military party; it was painted white. ^ On the trip across from Ensenada, Mr. Barnhart and I alter- nated taking samples of water from the surface of the sea. These water samples were collected by tying a small bottle to the bottom of a silk net. Three full buckets of known capacity were poured into the net, the plankton collecting in the bottle. The minute animal and plant life was killed and preserved with formalin, a label was added and the sample packed away for use of Dr. W. E. Allen in oceanographic study. These samples were taken every hour during the cruise, when the vessel was under way. »See fig. Nat. Geog. Mag., Vol. 44, No. 1, p. 72, July, 19J3. \0L. XIV] HAXXA— EXPEDITION TO GUADALUPE ISLAND 227 While camp was being established on shore, Mr. Slevin and I walked up the canon back of the buildings about a mile. The country is excessively rough and shows evidences of volcanism on a grandiose and awe-inspiring scale on every side. Huge caves and caverns festooned with ragged lava line the chffs on both sides of the canon. In some places strata of scoria, cinders and loose rocks are bedded as if they might have fallen in water from a spouting volcano. Subsequent to deposition the beds were violently disturbed because it is not unusual to see the dip of the strata change 90° in 100 yards. No fossils of any kind were found so it cannot be certain that any of the material was laid down in the sea. The caiion showed evidence of considerable water at a not very distant date. Large water holes, lined with fresh sedi- ment were in the bed of the stream but not a spot now ap- peared to be moist. All of the vegetation in that vicinity was likewise dry except the poppies and one or two other kinds of plants. Wild oats, waist high, grew^ in profusion where there was soil. Goats w^ere excessively abundant everywhere and were well fed. Doubtless there had been sufificient rain in earlier months to produce plenty of pasturage. But the dried bleached bones strewn over the ground in greatest profusion showed that famine had spread over the herd in other years and had taken enormous toll. Probably, as in most of Lower California and the outlying islands, rain is scant and very irregular on Guadalupe. Certainly the greatest part of the island is a desert of the most barren sort. No cats were seen during the brief sojourn in the caiion that evening and during the rest of our stay on the island they successfully evaded us. Several skulls w^ere collected at various places. Mr. Hinkley took one from a well (salty) at the land- ing place. Another was later found at the extreme south end of the island shown'ng that this pest has completely overrun the place. Escaping as pets or abandoned by former occupants, this animal has reverted to the wild state and has wreaked havoc among the birds. We saw evidence of this everywhere we went. The Kaeding's petrels were apparently preyed upon the most. The action of the cats could be plainly read from the record on the ground. The petrels live among the loose 22g CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. rocks and in the holes of the cliffs, where the cats apparently have no difficulty in capturing them as thej^ go and come. Many were seen with only the top of the head eaten away. In this cafion we took five species of land snails : two Pupil- lid?e; two Micrarionta and the strange Binneya iiofabilis found elsewhere only on Santa Barbara Island, off southern Cali- fornia. Here on Guadalupe it is very abundant and appears to be identical in every way with those of the northern island. It is about halfway between a true snail and a slug. Many of the snail shells had been broken and the soft parts extracted by mice. The house mouse is apparently very abundant all over the island; specimens were collected which do not differ from individuals of other lands. The species probably came acci- dentally with personal baggage, has increased enormously, and probably will completely exterminate the land shell fauna. Probably numerous species of insects have already disappeared through this agency. The cats, of course, will not eat the mice as long as they can subsist on birds. Mr. Slevin looked carefully for lizards on many parts of the island but failed to find a single one. Prof. Cuesta-Terron stated that he had a report of a specimen having the characters of a Xantusia but it was not sufficiently reliable to be credited without supporting evidence. Mr. Slevin's failure to find a species of reptile of any kind naturally leads us to believe none lives there. Late in the evening of July 1 1 an osprey was shot at the landing place ; this species had not previously been reported from Guadalupe Island. On the morning of July 12, with all hands on board the ship sailed around the north end of the island to the elephant seal rookery. On the way around, the beach was scanned at close range for Guadalupe fur seals but none was seen. Only in one place, a cave three-fourths of a mile north of the elephant seal rookery, did there appear to be any suitable ground where the fur seal might be expected. This was occupied by a few of the elephant seals. The landing was made early in the forenoon at the north- west end of a short beach composed of black sand and on which \< L. XI\'] HANNA— EXPEDITION TO GUADALUPE ISLAND 229 the elephant seals were located. Immediately back, huge, un- scalable, lava clififs rose to an elevation of 2000 feet. It was with much misgiving that we rowed in as quietly as possible, each moment expecting the animals to catch our scent or the noise of the oars and desert the place for the rest of the day. That invariably would have been the procedure if we had been approaching any of the northern rookeries of hair seals or sea lions I had visited. But they let the first boat load of us land without troubling themselves at all ; the nearest ones, however, were some 50 yards away.*' (See pi. 16, fig. 1.) With motion picture equipment and Graflex camera we climbed a spur at the west end of the rookery and proceeded to take a series of pictures as rapidly as possible. Each turn of the crank and each snap of the camera I expected to be my last opportunity, but the lazy animals slept on. Other visitors coming ashore hid under a low cliff until the photography from the distance was finished. Some of them were then asked to walk slowly toward the herd. It was expected that a motion picture of them all rushing into the sea would prove an item of interest. Every one was equally surprised when the men walked right out among the huge beasts, slapping an occasional one on the back as a sign of greeting. A count of the herd was made from this high point before the men went among the animals but it was subsequently dis- carded when it was found that a much more accurate census could be obtained from enlargements of some of the photo- graphs. We thus determined the number present to be 264. All of those present were males except one female. She was timid and left the beach soon after we arrived. It was noted that the long pendant snout of the male was represented in the female by a short and scarcely noticeable elongation. I do not believe the female can inflate her "trunk" as does the male and thus produce a resonance chamber or sound box to accentuate the ponderous snore-like sound the latter frequently make. There was one young seal on the beach, perhaps a yearling, and its silvery coat of hair fairly glistened in the sun. It like- wise deserted us soon after we made our presence known. « Anthony (Journal Mammalogy, Vol. 5, No. 3, Aug., 1924, pp. 145-152, pis. 17-20) has given an account of the elephant seal herd in 1922, 1923, and contributed other data of historical value. September 5. 1925 230 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. On the beach, down among the animals we made many close- range studies and photographs. (See pi. 16, fig. 2.) This was shedding time^ and we were all much surprised to see some animals with large flakes of epidermis peeling off of their bodies, bringing the old hair with it. Much of this cast-off skin littered the beach. The underside of the neck of the well grown male was very greatly creased and corrugated, and the color was brilliant geranium pink. Otherwise the coloration was a somber drab or gray, like the unspotted hair seals to which they are somewhat distantly related. The corrugations on the necks have been called scars from fighting, but they seem to be too regular and unifonn. I think it is purely a sexual character of the species. The only fighting scars I saw were on the backs. The animals were all excessively fat. On those occasions when we were able to get one to go into the water, wrinkles or waves of fat traveled the length of the body as it moved on the sand, undoubtedly aiding in the movement forward or backward. In coming from the water great deliberation was shown, advantage apparently being taken of the last ounce of "push" in the breaking surf. Locomotion was exceedingly slow and laborious on land; the diminutive front flippers are used to a certain extent to pull the huge bulk forward but they and the muscles which actuate them are entirely inadequate. The hind limbs project backward at all times and while they are very serviceable in swimming they serve no useful purpose on land. One curious habit we noticed on land was the throwing of showers of sand up over and on the backs as they lay stretched out. The front flippers, one at a time are used for this and in some cases an animal looked like a huge pile of volcanic sand with flippers projecting at one end and nose at the other. Why this is done remained to us inexplicable when we left. On several occasions we succeeded in causing a full grown bull to raise his head and shoulders to their full extent; then they are considerably taller than a man. The teasing to which they were subjected caused only the mildest sort of protest. This consisted only of throwing the head back high over the ' See figure in Nat. Geog. Mag., \'ol. 44, No. 1, July, 1923, p. 77. Vol. XIV] HANN A— EXPEDITION TO GUADALUPE ISLAND 231 back and opening wide the mouth. On no occasion was an attempt made to bite one of us although ample opportunity- was afforded had the animals been so disposed. How different were they in their docility from an equal number of fur seal bulls, which would have torn us literally to shreds under simi- lar circumstances ! On two or three occasions members of the party would place a hand on the back of an animal and vault over, rather than go around. One of the strangest things to me about the elephant seals was the manner in which the snout (erroneously called trunk) was inflated, balloon-fashion, and allowed to dangle in the widely opened mouth when the head was thrown far back to utter the indescribably weird sound they make.^ The noise (it can hardly be called a note), although of very low pitch, has peculiar carrying properties and the source is difficult to locate. So far as we could see the snout (about 12 inches long) was put to no other purpose. It can be of no value in the capture of food, else the young and females would likewise be thus provided. The Mexican naturalists wished to obtain a specimen for their National Museum and this afforded an opportunity to investigate the food habits of the species. But the stomach was empty, except for some sand, and the natural food remains a mystery. The breeding ground proper is at the southeast end of the beach and above high tide mark. Here were the remains of six dead animals, too far decomposed for careful examination. From them it was supposed that the ground had not been occupied probably later than March and perhaps earlier. Many points in the life history of this strange beast remain unknown. For instance, where were the females and young? Certainly not around Guadalupe. It has been suggested that they migrate to the coast of Chile. This may be correct, but the animals seem ill adapted to so long a journey. Our obser- vations indicated that they were not so adept in swimming as such species as the sea lions. They could hardly catch the in- credibly swift pelagic fishes such as tuna, albacore, yellowtail. etc., which abound about Guadalupe. Moreover, there appeared » See figure in National Geog. Magazine, Vol. 44, No. 1, July, 1923, p. 76. 232 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. to be no records of the species between Guadalupe and Chile. Truly this is an animal of mystery. All of us were impressed with the apparent stupidity of the elephant seals. One man with a rifle could kill in a short time all of the herd then present. Years ago they were so butchered and the fat was rendered into oil. This continued to such an extent that the animal was supposed for a while to be extinct. It was very gratifying to us to see that there was at least a nucleus left to perpetuate the species and at least not yet will it follow the dodo and passenger pigeon into oblivion. After making due allowances for animals absent it would seem that the entire herd in 1922 must have contained not many fewer than 1,000" of all classes. Upon our return to San Francisco the Committee under whose auspices the expedition was organized, took steps imme- diately to urge the Government of Mexico adequately to pro- tect this relic of a bygone age of which it happened to be cus- todian. Our associates from that country took similar action and as a result on October 27, 1922. President Obregon issued the following proclamation declaring Guadalupe Island a reservation. SUBJECT Marginally a stamp which says : — United States of Mexico. — Presidency of the Republic. — Resolution of the Bureau of Agriculture and Public Works : CONSIDERING That the island of Guadalupe, of Lower California, and its territorial waters possess natural riches alike in forestry material and in herds, and in game and fish, numbering among its species many of rare occurrence, which species are in danger of extinction, owing to the immoderate ex- ploitation of which they have been the object; That the Federal Government must protect those species which con- stitute an inexhaustible fount of riches for the Government and the people of Mexico. For that reason, I have considered it well to dictate the following RESOLUTION. Article 1. — The island of Guadalupe of Lower California, as well as the territorial waters surrounding it, remains reserved for the protection and 'Anthony (Jouni. Mammalogy, ^'ol. 5, No. 3, Aug., 1924, p. 148) has stated that he believed 1250 total to be a conservative estimate of the herd in 1923, a year later. VcL.

It is to be hoped that all loyal subjects of all civilized nations will respect this decree and permit the elephant seals to live their lives and perpetuate the species for the benefit of future generations of mankind. After Mr. Tose had completed the making of the sketches he had in mind and had collected some accessory material, such as rocks, plants, dried elephant seal epidermis, etc., we sailed back to our shore camp. The articles mentioned were to be used for the preparation of a group of the mounted animals which the California Academy of Sciences had received sev- eral years previously and which was to be installed in the new Steinhart Aquarium, then under construction. At the elephant seal beach, Mr. Anthony and others saw a wandering tattler fly listlessly from rock to rock in the most unconcerned and nonchalant manner. This bird has always been an enigma to me. I have seen it in summer on practically every north Pacific island I have visited from Guadalupe to the center of Bering Sea, and others have reported it as far south as the Revillagigedo group. Yet breeding records seem to be entirely wanting. It spends our winter months in the southern hemisphere and there is a possibility that its breeding ground is south of the equator. On the way back from the elephant seal beach to our shore camp two yellowtail tuna were caught from the deck and proved to be a desirable addition to our already excellent bill of fare. The fishes were taken on a bone "gig" trolled far 234 CALIFORNIA ACADEMY OF SCIEXCES [Proc. 4th Ser. behind the ship on a piano wire "leader" and very strong line. When a strike was made this powerful swimmer made the line fairly sing back and forth as it was hauled in, hand over hand. Such procedure would doubtless break the heart of a light tackle enthusiast but fishing for fun and fishing for food must always be separated. That night as we were getting into our blankets at 10 o'clock under a starlit sky, we were greeted by a slight earth- quake, lasting almost a minute — merely a gentle reminder of the immeasurable forces which have built this mountain peak from 12,000 feet beneath the waves to 4,000 feet above. The next day, July 13, the party separated in order the better to cover more ground in our limited time. Messrs. Slevin. Gallegos, Barnhart and Hinkley, leaving in the early morning, took the trail up the canon back of the buildings. After about six hours of steady, weary climbing, up the excessively rough lava slopes they eventually reached the forest of cypress trees near the top. Here Dr. Edward Palmer had camped in a ver- itable paradise in 1875. He found strange birds in abundance and a profusion of wild flowering plants. No less than four species of the birds he found are now absolutely extinct and except for the museum specimens and his notes they are forever lost to humanity. There is some strange and lonely sadness that comes over us when we think of the last of a species of one of nature's creations having passed its span of existence. Paleontology tells us that hundreds of thou- sands of species have so passed on in times gone by ; neverthe- less, when v'e see one go we feel the loss the same as we do when a dear relative has received a last farewell. The species of birds thus far exterminated on Guadalupe are: Guadalupe Caracara, Guadalupe Flicker, Guadalupe Towhee, and Guadalupe Wren. The caracaras were abundant when Dr. Palmer was at the island but ten years later (1885), when Mr. Walter E. Bryant collected on Guadalupe for the California Academy of Sci- ences, he found them being killed by the soldiers stationed there "to protect the goats." It was evidently believed that the young kids were killed by the caracaras and, although the birds ranged from the sea shore to the highest peak, they were Vol. XIV] HANN A— EXPEDITION TO GUADALUPE ISLAND 235 soon all killed. The destruction was made easy because, it is said, the birds resorted to the water holes on top of the island to drink. The other three lost species, the flicker, wren and towhee, have gone because they were unable to protect themselves from the house cats, running wild. Our party saw no sign of any of these four species although special search was made for them. There was one other resi- dent, the Guadalupe petrel, which we expected to find but did not. The last report of a naturalist previous to our visit ( 1906) stated that the birds were being rapidly killed by the cats. Our visit was too late in the season for us to say if all are gone or not. In the vicinity of the spring near the cypress grove the party estimated the number of goats at 5,000. Naturally the water hole was in a foul and filthy condition. The animals have in- creased to a prodigious extent since they were first "planted."^" There are two stories told as to the early introduction of this pernicious pest on Guadalupe. One has it that the early whalers sailing from New England "planted" goats on all of the out- lying and uninhabited islands in their track in order to provide a supply of fresh meat for their crews without the necessity of visiting a port where risk of desertion was always great. This version may be true, but when Dr. Palmer was on the island in 1875, the animals were there but had not increased sufficiently to cause any damage. In 1885 Green^^ stated there were many thousand. The other version came to me after I returned to San Fran- cisco. It was related to me by one John McCormick. One of the early whalers, Captain Breen, obtained a concession from the Mexican Government to raise goats on Guadalupe and in- troduced the nucleus of a herd there in 1872. This concession passed to Captain Breen's son who in turn willed a one-third interest to Felix Franquient and two-thirds to Sammy Solo- mon. EfiForts to confirm this story were unsuccessful. Mr. Mc- Cormick told me he had reports that there were several million goats on the island and when informed that our party esti- mated the number at 40,000 to 60,000 his interest waned ! " See fi^re in Nat. Geog. Mag., Vol. 44, No. 1, July, 1923, p. 84, from photograph by J. M. Gallegos. "Bulletin Calif. Acad. Sci., Vol. 1, .■\ug. 29, 1885, p. 215. 236 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. However the goats originally reached Guadalupe, they have increased enormously and through inbreeding have developed into a motley race colored white, red, brown, spotted, blotched, and black ; curious malformations of horns have also resulted. They are at perfect ease on the tablelands of the top, on the perpendicular cliffs of the seashore or the steep-walled cavern- ous canons. They were not very shy at the time of our visit. Two of them took up a station on the face of a vertical cliff close behind our camp and the ledge on which they had a foot- ing was so narrow they apparently could not turn around to get back the way they went. Their bleating was somewhat annoying at times but finally one of them half jumped, half slid, to a talus slope 50 feet below. A safe landing was made and the goat trotted away as if that was an every-day occur- rence. The cowboy propensities of one of our deck hands finally became irresistible and he lassoed the other animal and hauled it down.^- Several times we saw goats go deliberately to the sea and drink, and we were satisfied that this was practically the only method the majority of them have of quenching their thirst during the dry season. It is believed that many of them never visit the sources of freshwater on the island. The party, while on the top of the island, collected a consid- erable supply of seeds of the Guadalupe cypress, a marvelously beautiful and graceful tree, entirely distinct from all other known cypresses. It is sometimes called "blue cypress" because of the blue-gray color of the foliage. For many years, the species was represented in California only by a few beautiful specimens on the grounds of the state capitol at Sacramento, two smaller ones in Golden Gate Park, San Francisco, and some others in Balboa Park, San Diego. None of these had ever produced seed. Therefore, Mr. John McLaren, Superin- tendent of Golden Gate Park, was very grateful for the supply of seeds brought back to him. A great many of them grew un- der the expert attention they received and may be exi>ected to furnish shade to the children of the park long after the last one on Guadalupe has been "barked" and killed by the goats. Those who saw the grove there in 1922 stated that no small " See figure in Nat. Geog. Mag., Vol. 44, No. 1, p. 82, July, 1923. Vol. XIV] HAXMA— EXPEDITION TO GUADALUPE ISLAND 237 trees were found at all. The goats evidently eat every seedling which starts. In addition they had peeled the bark from many of the large trees to a point as high as they could reach. The presence about the water hole on top of the island of a horse, six mules and 14 burros caused considerable astonish- ment to the party some of whom would have liked immensely to have received some assistance from these sturdy animals before they succeeded in negotiating the steep descent of the mountain. They reached camp, greatly fatigued, soon after dark. Mr. Anthony and I rowed south from the landing, six or seven miles in order to make a careful search in the water and on land for fur seals but the quest was fruitless. We landed at the first large caiion south of the buildings and spent two hours collecting on shore. Signs of house mice showed that these animals were excessively abundant. The rock slides were occupied by numerous Kaeding's petrels. These birds are chiefly nocturnal in their movements on land, and each night at our camp we heard them chattering among the rocks and canons. Several were attracted to the lights on the ship and were captured easily. They are evidently not as expert on the wing as one would be led to expect by watching the birds gracefully skim the waves of the open sea ; Mr. Slevin found two dried carcasses impinged on the thorns of the "cholla" cactus. On July 14 Messrs. Anthony, Slevin, Terron, Barnhart, Tose and I rowed southward to a large caiion (Esparsa Caiion) which opens to the sea about three miles south of the Northeast Anchorage. The primary object was to secure seeds of the palm trees, about 1,000 of which grew above an eleva- tion of 750 feet at this place. No ripe seeds were found and small trees which could possibly be transplanted were missing. Evidently not a new tree has started for a great many years, another blot against the goats. (See pi. 19, fig. 2.) We succeeded in collecting a few other species of plants which the goats could not reach. Our method was to scale a cliff as far as possible and then shoot a fragment of the plant from its place of growth. Practically nothing edible for the goats could be reached by us ; they are better cliff climbers 238 CALIFORNIA ACADEMY OF SCIENCES [Proc. s'th Ser. than we. Several things indicated that there might be fresh water underground in this canon or as springs farther up. The remainder of the party either worked in camp or in that vicinity during the day. Early on the morning of July 15 Messrs. Terron, Anthony, Slevin, the engineer of the Tccatc and I went to the top of the pine ridge, a knife-like promontory 2,500 to 4,000 feet high, on the northwest end of the island. We ascended from the first canon north of the Northeast Anchorage and followed the crest of the ridge southeast about three miles. Enormous, senile, wide spreading pines were very common on the top; some of them were beautiful specimens but many were dead or dying and a great many more had fallen. When we stopped on our southward march the pines were growing scarcer and the beautiful Guadalupe oak had appeared in con- siderable numbers. Both of these trees are peculiar to Guadalupe and it is said there is not a living specimen of the oak elsewhere and very few pines. We were very anxious to secure acorns but system- atic search failed to reveal a single one. We even climbed numerous trees in hopes of finding one lodged in a crotch or cavity but this failed. One botanist has stated that the acorns of this oak are the largest in existence so we were greatly dis- appointed in our failure. With the pines we were more successful and a large supply of cones was brought back. As with the cypresses and palms, the goats have for many years effectually prevented any new growth and if some one does not succeed in transplanting the oak this beautiful species in a few more years will be forever lost. The top of this ridge and a considerable distance down on the seaward side is bathed in almost constant fog. It was only between banks of this that we were able to get a glimpse, now and then, of the country round about and to take some pic- tures. The trees condense a great deal of moisture from these clouds and underneath many of them the ground was very moist. Sr. Cuesta-Terron suggested that if Guadalupe could be made a government reservation it should be possible to fence Vol. XIV] HAXNA— EXPEDITION TO GUADALUPE ISLAND 239 certain favorable forested areas of all the species of trees and thus keep the goats out. If this admirable idea can be carried out it no doubt will serve to perpetuate in their native habitat the five species which are otherwise doomed to certain extinc- tion when the present generation of individuals is gone. These are the oak, pine, palm, cypress, and cedar. We found none of the beautiful undergrowth of shrubs and succulent plants of this forest which was so fascinating to Dr. Palmer 50 years before. It is believed that about 100 native, endemic species of plants may have been entirely exterminated by the goats in this time. We were greatly disappointed at finding no flickers, wrens or towhees. The dusky kinglet was also not seen although it had previously been found in the trees we visited. We did see about 15 individuals of the red-breasted nuthatch and many Guadalupe juncos. Guadalupe rock wrens and Guadalupe house finches were very abundant. Apparently these species had com- pleted the rearing of young for the year and no eggs were found. Three red-tailed haw^ks were seen; this species is com- mon on the island and was seen almost every day. A great blue heron was seen on shore. Messrs. Tose and Hinkley worked closer to camp during the day and after the pine ridge party had returned the shore camp was broken and all hands went on board the Tecate for the night. Mr. Barnhart had spent the day studying the fishes about the shores near camp. Our facilities did not permit the preservation of an extensive collection of this interesting group, a fact which we regretted whenever we saw the intense blue Azurina hirundo over the kelp gardens. Mr. Anthony had helped to collect the type and two other specimens of this* beau- tiful fish 25 years previously and they still remain the sole museum records of the species. We saw considerable numbers of them, but never many at one time ; they persistently refused to take any bait we had to offer. One of the most striking features of Guadalupe was the very unusual tameness of some of the birds. Rock wrens'^ were at almost every landing and juncos and finches were abundant among the trees. (See pi. 17, fig. 2.) All three species were most confiding and fearless in their behavior. If we sat down See figure in Nat. Geog. Mag., Vol. 44, No. 1, July, 1923, p. 73. 240 CALIFORNIA ACADEMY OF SCIEXCES [Proc. 4th Ser. to eat a lunch and remained motionless for a few minutes, one or more of them would alight on our boots or hats. The strange part of it is that the cats have not as yet exterminated these species as well as some others. This habit was in great contrast to all species on Cedros Island visited a few days later. There the birds, all species, were so wild and wary that it was almost impossible to collect specimens. I know of no explanation of these facts. Human beings visit one island as often as the other and probably never have the small birds been molested in either place other than by collectors. The next morning, July 16, at eight o'clock, the ship got under way and sailed around the north end again to the ele- phant seal beach. The shore and caves were examined closely by rowing along just outside the surf line; we had high hopes of being as fortunate in our location of fur seals as we had been with elephant seals but there was no sign of the objects of our search on this end of the island. At the last cave before reach- ing the elephant seal beach there were 22 elephant seals hauled on a small sand bank and 14 just outside in the water. There appeared to be more of the animals on the rookery beach than on the day we made the count but we did not stop to check the earlier figures. Cruising on down the west side of the island slowly we examined minutely every nook and corner where it appeared at all likely fur seals might be. At one p. m. we anchored off Jack's Bay, halfway down the island and went ashore to ex- amine the ancient fur-seal rookery ground. Here was located originally a rookery with as many animals on it as any of the largest breeding grounds of the Pribilof Islands. The boundaries of the great rookery could be traced almost exactly by the smooth and polished rocks which had been worn this way by the trampling of thousands upon thousands of flip- pers for many, many years. At the western end of the rookery there was the outline of the hauling ground for the adolescent males, the bachelors, extending far back of the beach line. And back of it there was a canon with a causeway, fenced off with built-up rocks and logs of the native palm tree. The latter were thoroughly decayed showing that a great many years Vol. XIV] HANNA— EXPEDITION TO GUADALUPE ISLAND 241 had elapsed since they were put in place. At the upper end of the causeway on a little tableland was a corral, partially demol- ished. The rookery proper occupied a fringe on a boulder beach about half a mile long lying east of the hauling ground. In front, and awash during the highest waves, there is a rough and jagged lava reef. The tide pools of this undoubtedly fur- nished admirable places for the young pups to learn to swim. At the eastern end of the rookery was what appeared to be the killing ground and a flat smooth area for pegging out the skins to dry. In the early days of fur-seal work this method of curing was employed instead of the use of salt which has been used now for about 75 3^ears. At the eastern end of the rookery were the rock walls of eight houses. No framework was left. They were probably covered with the skins of the elephant seals. We could not walk over this deserted ground without form- ing a picture of the grand sight it must have been when the first visitors built their rude huts and began the relentless slaughter of the fur-seal herd. Those who are familiar with the history of the Alaska fur-seal herd know what a waste there has been. It is recorded that the killing was done by Aleutian islanders brought down by the intrepid Yankee sailors for the purpose. The Aleutians were under the domination of Russia at that time and the Americans were able to arrange to do the work on shares ; they were navigators, the Russians were not. It appears that parties of the Alaskan natives were landed with water at the rookery grounds and there left to make the season's catch. After the work was done the ship returned for them and took them away again. Evidently the greatest need was for water and a well had been dug near the buildings. It had caved in badly and showed no sign of moist- ure of any kind in the bottom. It was here at Jack's Bay that Dr. Charles H. Townsend collected four fragmentary skulls of fur seals in 1888. They were found to represent a species decidedly distinct from the Alaska fur seal ; in fact they were more closely related to those that live in the Antarctic regions than to those of the Arctic. The Guadalupe species was named Arctocephalus townsendi by 242 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Dr. Merriam, and the four skulls in the original collection form the sole representation of the species in the world. Al- though many people have searched for the species since, it appears to be extinct. In going over the rookery ground we had expectations of finding bones but were disappointed. It appears that in this desert air bones disintegrate very rapidly and fall to a powder. Even some bones of goats were almost completely destroyed and they could not have been there longer ago than about 1880. The great fur-seal rookeries were exploited chiefly between the years 1800 and 1810. Here at Jack's Bay Messrs. Slevin and Tose collected vari- ous and sundry species of insects and shells and succeeded in getting one house mouse. This is a dry, barren part of the island and the mice have lived here for many generations, without water the greater part of the time, yet they do not appear to differ from this pest elsewhere. I here succeeded in finding in the rock pools a few indi- viduals of the marine shell Uvanilla regina Stearns, a beautiful species originally found on Guadalupe and not certainly known elsewhere. That afternoon we sailed slowly down the remainder of the west side of the island but finding nothing of importance we anchored in the bight known as "South Anchorage" for the night. Two fair-sized islets at the south end of Guadalupe known as Inner and Outer islands were examined minutely for fur seals but none was found. On a shelf of Inner Island we saw 14 California sea lions sleeping quietly in their solitude. These islands are very interesting geologically. One is built of lava, like most of Guadalupe, and is a crater, bowl-shaped on the inside. The sea has eaten into the rocks so that a per- pendicular wall is left all around. Next day from an elevation on Guadalupe we could see water inside the crater, but whether it was fresh or salt could not be determined. The other island rises out of the water, a sheer monolith with perpendicular walls going down into deep water. This one was composed of a light brown massive rock very decidedly different from the stratified lava of which the crater is built. Vol. XIV] HANNA—EXPEDITIOX TO GUADALUPE ISLAND 243 In the early morning of July 17 Messrs. Anthony, Tose, Hinkley, Barnhart and I went over the reef ground near South Anchorage, this being an excellent hauling place for fur seals should any be around, but not a sign of an animal was found. Fig. 2. Sketch of South Rookery, an abandoned fur seal breeding ground on Guadalupe Island. — 1, Steep escarpment leading to high land above. — 2, Main rookery ground, excessively rough with blocks and boulders of lava; many worn smooth and polished from trampling of the fur seals. — 3, A wrecked dory. — 4, Squares represent walls of human habitations. — 5, Trail leading to smooth tableland about 50 feet above level of rookery. — 6, Smooth sandy area used for pegging out seal skins to dry. — 7, Round, flat topped piles of stones, presumably used for platforms for piling skins. At one time this area was occupied by a vast rookery of Guadalupe fur seals. As at Jack's Bay the boundaries were plainly traceable by the flipper-polished rocks. The rookery occupied a stretch of coastline at least three-fourths of a mile long, the rocks being greatly worn; evidently the ground was occupied for a very long period of time and if this feature be a safe means of estimating the age of a rookery, then Guada- 244 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. lupe was inhabited much before the Pribilof Islands by the herds there. On top of a tableland was a smoothed-off area used as a pegging-out ground, in many cases the pegs were still present but grealy worn by the wind blown sand. Piles of boulders, carefully arranged in circles may have been used as a place to put the fresh skins before pegging to keep them clean and free of sand ; no other use could be thought of to which they might have been put. (See pi. 15, fig. 2.) Near the beach line there were the remains of the stone walls of nine houses, similar in every way to those previously seen at Jack's Bay. (See pi. 17, fig. 1.) The country at this end of the island is an exceedingly bar- ren desert, where even the goats find difficulty in maintaining an existence. The uplands were very rough and rugged with strewn lava and in one patch of this a little cactus belonging to the genus Mammillaria was collected. Until then the only other form of this group found was the "cholla." Under some vegetation near the beach Mr. Slevin and I col- lected two species of Hemiptera and two beetles we had not previously found on the island. In the afternoon we continued slowly with the ship up the eastern side of the island, examining the shores very carefully for fur seals. About two miles north of the south end of the island we found more ancient rookery ground, the occupied area being only about one-half mile long, but near by were the remains of 19 houses. Evidently this was the most favorably located of the rookeries for human habitation although we could see little reason for choice in the matter. Probably the workmen here walked across to the other rookeries for sealing work. Of course we were much disappointed at finding no living fur seals. It would seem that if the last hunters had left any breeding animals at all, they would have increased sufficiently by now to have been seen under the close scrutiny we gave the shores. The absence of bones on the old killing fields and rookeries also disappointed us because we had hoped to be able to add at least some pwDrtions of skeletons to the collections. After we had cruised northward along the eastern shore to the point where we left off with the rowboat a few days before, Vol. XIV] HANNA— EXPEDITION TO GUADALUPE ISLAND 245 the ship was headed for San Qiiintin Bay on the peninsula of Lower California. This we reached at two p. m. of July 18 and Messrs. An- thon}-, Tose, Slevin, Barnhart and I went ashore to collect on the west side of the bay. Miscellaneous specimens of various kinds were taken, among which were a rattlesnake and a lizard, found by Mr. Slevin. These pleased him very much because up to this time he had not gotten anything for the Department of Herpetology. He had been unable to verify the vague reports of the lizard on Guadalupe.^* The remainder of our party went ashore on the east side of the bay at the village to arrange for the use of an automobile the following day. The next morning, July 19, Messrs. Angulo, Cuesta-Terron, Anthony, Slevin and I secured a light automobile in the village of San Quintin for use during the day. Mr. Green, the post- master, owned the machine and we drove northeastward about 15 miles, diagonally across a level plain, then over gently roll- ing hills to the mouth of a cafion which comes out of higher mountainous country to the eastward. At the mouth of the canon there is a huge land-mark in the form of a red rock escarpment and near by a well kept farm has the name "Red Rock Ranch." We were treated to huge figs, four inches long, delicious watermelons and tomatoes, all irrigated with water from the stream in the cafion. From the ranch we drove up this stream about three miles to the Mission of Santo Domingo, once a populous and impor- tant station on the line of civilized habitations from the capital of Lower and Upper California, Loreto, to San Francisco, Now a few natives were left and they seemed to be fairly prosperous, with well kept farms and houses. Conspicuous among the buildings was a schoolhouse which would be a credit to many small communities in the United States. The "dobe" walls of the mission yard were mostly in ruins but one of the buildings was still well kept and was used regularly for church services, " See Green, Bulletin Calif. Acad. Sci., Vol. 1, 1885, p. 220, who reported having seen "two or three small lizards." Mr. Slevin thinks that if a species of lizard did once live on the island it is probable that the cats have destroyed them all by now. September 5, 1925 246 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Collecting in this vicinity was not particularly encouraging so we returned early to the plains where a few antelope ground squirrels were taken as they rested, bird fashion, in the tops of the sage brush. Also just before dusk Captain Angulo and others derived considerable pleasure in securing some jack rabbits for us for specimens. I had missed an easy rifle shot at a coyote early in the afternoon and it took me some time to recover. The village of San Quintin consisted of a few miscellaneous houses, the most conspicuous of which was the old "Company House." Many years before, this had been the scene of con- siderable activity by a "colonization" company but it did not turn out well. Mr. Anthony had been with the company as a surve3^or and had collected many valuable specimens of birds in this vicinity. The place was also interesting to those of us from the California Academy of Sciences because our Secre- tary, Mr. W. W. Sargeant, had also been on hand with the first contingent of "settlers." While we were working on the east side of the bay, Messrs. Gallegos, Tose, Hinkley and Barnhart collected on the west side and secured many valuable specimens. On July 20, Messrs. Anthony, Gallegos, Slevin, Barnhart and Tose worked on the west side of the bay adding many more specimens to our rapidly growing collection. I found it profitable to visit some low cliffs, not over 20 feet high, on the east side of the bay and just south of the village. Here I succeeded in getting a very large collection of fossil shells consisting of several thousand specimens. The geology in the vicinity of San Quintin is comparatively simple. In late Pleistocene the present bay was a broad inden- tation of the sea and ocean-living species were very abundant. Subsequent elevation raised the bottom on the east side in a broad fold. The preservation of the fossil shells is excellent, many of them retaining some of the original coloration. How far back toward the foothills this embayment extended cannot be determined but probably it went to the first terrace, the be- ginning of a long series of rolling hills or mesa. This terrace is said also to contain fossils but none were secured. It is probably much older than the outcrops on the bay. The moun- Vol. XIV] HANNA— EXPEDITION TO GUADALUPE ISLAND 247 tainous country to the east of this terrace is metamorphic, the age not having been determined. On the west side of the bay there is a chain of low volcanic cones not over 300 feet high. Lava has spread outward from these as far as the bay shore and on top of a broad shelf of this there are other Pleistocene marine sediments but with a dif- ferent set of fossils. Among those collected were some huge Schizotherous clams, fully eight inches long. The broad plain east of the bay was once occupied by great numbers of deer and antelope but they have almost disappeared on account of the activities of "sportsmen" from further north, and hunters employed by mining companies to provide fresh meat for their camps. On July 21 we completed our work at San Ouintin Bay. Messrs. Anthony, Slevin, Tose, Gallegos, Hinkley and I all worked at collecting on the west side. A few insects were found but no species was abundant. Coyotes, wood rats, and rabbits were abundant, as well as several species of desert field mice. One of the rarities collected was a very small species of shrew. Birds were very scarce about the bush-covered hills, Bell's sparrow being the dominant form. Mr. Slevin succeeding in securing eight rattlesnakes for the collection, a few of them being taken by other members of the party. There is no ques- tion but experience in this as in other lines makes for efficiency. He seemed to know just which brush thickets to explore and with his little .22 caliber shot pistol he captured three other species of snakes as well as a large number of lizards belonging to five or more species. Three species of land snails were very common among the brush thickets on the west side, the most noticeable one being the large Micrarionta stearnsiana here about to the southern extremity of its range. We left the bay at four p. m. and slowly made our way out through the tortuous channel at the entrance. This is so diffi- cult to follow that it would be dangerous for a boat much larger than the Tecate or for a navigator unfamiliar with the water. During the night Mr. Barnhart took water and plankton samples at regular intervals on the way to Cedros Island. I 248 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. relieved him at five a. m. At one place a peculiar temperature condition was found ; this dropped about five degrees in a dis- tance of eight miles and rose suddenly on the opposite side. This was interpreted to mean a submarine obstruction to the free flow of currents and a consequent "up-welling" of the colder waters from below. At eight a. m. of July 22 we were in sight of Cedros Island and the east shore was followed southward. The sea was with- out a ripple and as we cruised close in shore we were able to note some of the interesting features of this remarkable island. Near the north end we passed the site of a copper and gold mine, abandoned long ago. It was visited later and notes were made of surroundings. Nearly every slightly elevated rocky pinnacle or promontory along the shore was occupied by a pair of ospreys with their nest. In some of these young birds could be seen, almost as large as their parents. About halfway between the north end and the Grand Caiion in the center of the island, a crosswise fault extends northwest. On the south side of this break what appeared to be Tertiary sediments had been elevated about 200 feet above the sea. This deposit extends southward about two miles and is lost beneath the sea due to another fault. This elevation is entirely distinct from another which has lifted the greater part of the east side of the island out of the water about 20 feet. The old beach line was plainly seen from the ship. At noon we landed near the south end of the island where Bernstein Brothers of San Quintin and San Diego have an abalone packing plant. They have two outlying collecting camps with two divers each and enough of these fine mollusks are obtained to keep 14 shore men employed. The plant consisted of boiler, cooking vats, and wire drying frames. Canning machinery and a dock were in course of in- stallation. They had a large launch which made regular runs to San Diego and two smaller ones to attend the collecting camps. The abalones were brought in in the shell and consisted chiefly of the species, Haliottis corrugata. The meats were cooked three times in boiling water at intervals of a week or Vol. XIV] HANN A— EXPEDITION TO GUADALUPE ISLAND 249 two. Between times they were dried in the sun on the wire netting, the entire process taking about six weeks. The meat when dry is hard as a piece of untanned leather and is brown in color but it has a very agreeable flavor. The product is shipped to China and Hawaii, some of the shells going elsewhere to various markets. It was stated by the Superintendent, Mr. Charles Bernstein, that five tons of fresh meat made one ton dried. In the afternoon all of the party went ashore for collecting. Most of us followed the pipe line inland about two miles and thence another mile to a large spring. Here a permanent sup- ply of very good water is had. At the source a very consid- erable area is grown up with rank water vegetation and no doubt the accumulation of this through years has retarded the flow of water somewhat. If it were cleaned out probably a sufficient supply could be had for much greater industrial needs or even a limited amount of irrigation. Tracks of deer and goats were abundant about the spring and a few small trees cast a most welcome shade. Birds were excessively scarce and so wild as to be almost unobtainable. Some rather interesting insects were found, among others be- ing a huge dragonfly four inches long. Numerous land shells peculiar to Cedros Island were picked from certain desert plants. They were hibernating in closely-sealed shells. In the spring, large numbers of a minute freshwater gastropod were found, probably belonging to the genus Paludestrina. Also there and in the stream leading to the pipe line entrance, Mr. Slevin collected numerous specimens of a small frog. Here we made our first acquaintance with that strange mon- strosity, the elephant tree of Cedros. It grows very close to the ground, the highest being not more than about 12 feet tall. At the base many of them were fully two feet in diameter and the thick club-shaped limbs taper rapidly to nothing. The trees had shed their leaves but were in full bloom, each one a gor- geous mass of beautiful pink. We made a much more extended stay on Cedros on our re- turn and detailed observations will be left until we come to that. But that evening Mr. Anthony and I put out many traps hoping to catch a very small pocket gopher which I saw during 250 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. the afternoon. Our attempt was futile, but we did capture a lizard in our trap which Mr. Slevin stated had not previously been taken on Cedros. Strange to say, he did not get another specimen. At seven a. m. of July 23 we sailed for Magdalena Bay, far to the southward. Between Natividad Island and the peninsula great numbers of cormorants were flying from east to west in long flocks. For half an hour they passed at a rate conserva- tively estimated at 100 per minute. Many petrels and shearwaters were seen but no albatrosses cared to follow us south of Cedros Island. During the day we sailed for hours through loose flocks of red phalaropes. They were evidently southward bound but found time to en- gage busily in catching minute animal life from the surface of the sea for food. On July 24 we had four hours' delay out at sea due to engine trouble, but our engineer seemed to be able to apply the proper remedy and we continued later to Magdalena Bay, arriving after nightfall. During our stop at sea a collection of surface dwelling organisms was secured with a dip net. Among the interesting forms thus secured were several larval fishes; among them we were able to identify pipe fishes, flying fishes, and the bonito or skipjack of the mackerel family. Some of these were barely out of the egg and they offer a possible clue to the breeding area of the tuna for which the naturalists of the U. S. S. Albatross searched in vain for several years. We passed Cape San Lazaro as the sun settled behind a bank of clouds on the western horizon leaving the brilliantly shining stars to light a tranquil sea. The atmosphere, the water, everything about us told us in unmistakable terms that we were approaching the tropics. As we entered the bay we passed close to Sail Rock, a target for the U. S. Navy in other days, and at nine-thirty p. m. we anchored in front of the village of Magdalena. During the trip down from Cedros Island whales were sighted only twice. The scarcity of these cetaceans was a surprise because it was in these waters that much of the pelagic whale industry was concentrated during the early part of the 19th century. Vol. XIV] HANN A— EXPEDITION TO GUADALUPE ISLAND 251 Swordfish and tuna were common on the way down and we caught a few bonito and skipjack on the gig. Some of the bonito contained ripe eggs indicating that the spawning season was at hand. Man-o-war birds, Heermann's gulls, elegant terns and brown pelicans came to meet us when we were about 15 miles out from the bay. In the late evening red phalaropes settled abun- dantly on the water ; some of them still retained the red plum- age of the breeding season. A black-footed albatross sailed past us in the afternoon and after one look departed in disgust. Least, Soccoro, black and Kaeding's petrels were common all day, their lazy but tireless flight often being the only sign of life on a glassy sea. In the morning of July 25 Messrs. Tose and Hinkley went south from the village along the bay shore and by noon had collected about 20 birds. Mr. Anthony and I went north to a mangrove swamp where four hours were spent in the almost impenetrable tangle, often up to the waist in mud and water. In this we succeeded in securing three specimens of the rare mangrove warbler but did not get one of the rails which we could hear from time to time. It is said that these birds blend into their surroundings so perfectly that it is only by long experience that the collector is able to secure them with regularity. Mr. Slevin worked north of the village and took about 70 lizards and two snakes. Magdalena Bay is so large that the eastern shore cannot be seen from the village on the west side. North and south there is inland water for about 100 miles, much of it shoal but the anchoring ground is large and safe. There are a great many sand and mud flats and lagoons lined with mangroves and coarse grasses. In these lagoons there were formerly great numbers of turtles and their bones and shells still line the beaches. California gray whales used to visit the lagoons but the species now appears virtually extinct. Porpoises, however, were often seen in the bay waters. The village of Magdalena consists of several frame houses and concrete warehouses. It was established as a concession granted to a colonization company, not now in existence. The 252 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser, chief source of revenue was the lichen called "Orchilla." This grows luxuriantly on cactus and other desert plants of the region and was shipped to Germany for use in dye manufac- ture until chemists working with coal tar derivatives obtained better colors. Boats seldom call at the village any more. A company of marines located here had just completed the erec- tion of a radio station. Water has to be brought by boat from the east side of the bay, there being none near where the village is located. The important commodity sells for 50 cents per barrel. On July 26 Mr. Anthony and I again visited the mangrove swamp and succeeded in securing seven more mangrove war- blers. Also three Xantus' jays were taken; this is likewise a rare species in ornithological collections. I was surprised to find numerous living specimens of a huge Littorina adhering to the semisubmerged roots of the mangrove. We walked across the sand dunes to the ocean beach to the westward where a considerable number of marine mollusks was collected. This seemed to be a favorite place for the cap- ture of turtles by the people of Magdalena. We counted 65 shells of those recently killed. The sex of at least 40 could be determined and they were all found to be females. It is said the turtles are killed with harpoons as they approach the sand beaches to lay their eggs. Mr. Slevin continued to add largely to the collection of reptiles, the most important being three specimens of a lizard called "whip-tail." He took four on the previous day; only one had been known previously. Other members of the party were variously engaged; Sr. Gallegos continued to add to his collection of insects and plants ; and Messrs. Tose and Hinkley worked with the birds continuously. On the morning of July 27 Mr. Anthony brought in all of the traps which had been placed out at this place. Very few specimens of mammals were taken and they were chiefly rats of the genus Neotoma and desert mice belonging to Pero- myscus and Perognathus. I spent the morning collecting fossil shells from a large de- posit which is exposed to an elevation of 20 feet above the bay Vol. XIV] HANNA— EXPEDITION TO GUADALUPE ISLAND £53 immediately north of the village a few rods. Here in a soft uiiConsolidated sand were great numbers of shells, many species being rare in collections. The age of the deposit is Pleistocene and it represents an elevated beach line similar to what has already been described at San Quintin and Cedros Island. Prior to this late elevation the land on which the village stands was an island and Magdalena Bay had a broad entrance to the northward. This permitted free entrance of ocean water and with it ocean-dwelling species of animals. With the eleva- tion of the land the north entrance was closed but the lagoon extending far to the northward inside the belt of seashore sand dunes is a remnant of it. It is said that this lagoon is connected with the sea to the northward thus in fact leaving Magdalena an island at present although it is more like a pen- insula. The mountains back of the village are metamorphic and igneous and therefore have been above the sea for a long period of time. During the Pleistocene at least, the range was an island, far removed from other high land, and even now partakes of the characters of an island. Therefore, it would be expected that sedentary animals such as mammals and in- sects, and also the plants, would have been modified by isola- tion and have become separate species or subspecies. This appears to be true in many cases. We left the anchorage at Magdalena at noon of July 27 and went to the village located on Santa Margarita Island 20 miles to the southward. To get there we had to pass through a rather difficult channel, the southern half of the bay being much shallower than the northern. Santa Margarita Island occupies the same position with reference to Magdalena Bay as the San Francisco Peninsula does to San Francisco Bay. The island has been subjected to the same elevation of Pleistocene sediments around the shore lines as has been described for other places. It is divided into two parts both the northern and southern being mountainous and composed of metamorphic or igneous rocks. The low pass two miles long, north and south, connecting the two parts, is level and on the western side is fringed by a belt of enormous sand dunes. Near the center of the isthmus country there is a zone of sedimentary rocks chiefly thinly bedded but hard sand- 254 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Stones. No fossils could be found in them but they had the appearance of being pre-tertiary on account of the alteration which has taken place. The strata dip to the westward about 80° and strike about northeast-southwest. A great deal of magnesite has been collected about the lower slopes of the mountains of both sections of the island. Com- paratively large quantities have been shipped out and some trucks and other machinery were still on hand. It was under- stood that under the laws of Mexico the concession under which the deposit had been exploited had been automatically cancelled not long before our arrival. The manner of forma- tion of the magnesite is an interesting problem, a solution of which was not evident from my brief study. The mineral seemed to be fairly pure and occurred chiefly as loose chunks or nodules having mammillary structure, as though deposited from mineral springs. Here at Santa Margarita was a well equipped plant for the manufacture of oil and meal from fish. It was idle at the time but in good condition. Apparently some difficulties had arisen in regard to the collection of the fish for working up. It was said that a small species resembling an anchovy was the chief raw material and no difficulty had been encountered in securing a sufficient supply by the use of a 200-foot seine on the neighboring beaches. By this method many other species were secured; particularly abundant were several species of sharks. Near the wharf there was a building which had been put up for use as a turtle cannery. It had a concrete floor and was used as a habitation at the time of our visit. Much of the machinery was still in place. We were infomied that the orig- inal concession had been granted many years previously to a man named O. Sandaval but no attempt at operation had been made for 15 or more years. The ship was tied up to the dock here and most of us went ashore. Mr. Anthony and I put out some traps and collected a few desirable birds. We also found a snake (a black racer) which Mr. Slevin considered very desirable. I found many excellent specimens of a species of land shell (Bulimulus) re- lated to a form which lives in the Cape Region farther south Vol. XIV] HANNA— EXPEDITION TO GUADALUPE ISLAND 255 on the peninsula. Mr. Hinkley secured a specimen of the endemic and greatly desired jack rabbit. Mr. Slevin secured all previously recorded species of reptiles except a rattlesnake. This seemed like a very excellent collecting station and we regretted that we could not spend a week or a month in the vicinity. Across the bay to the eastward the great and intri- cate mangrove swamps and islands invite the naturalist most enticingly. Mr. Barnhart found a strange water temperature condition in Magdalena Bay. Where we anchored at Magda- lena it was 64°F. Farther out and closer to the entrance it was 68°. Outside it was 74° and at Margarita it was 71°. Why is the water so cold in the north part of the bay? We could not suggest an answer. On the morning of July 28 we found only four mammals in the traps, two wood rats and two mice (Perognathus). I shot two bats near the wharf in the early morning light as they were flying along a low cliff near the fertilizer plant. Mr. Slevin and I walked south into the mountains of the south half of the island, thence to the "ranch" on the west side of the isthmus, and back through the mountains of the north half. Numerous interesting birds were taken some of which belong to the fauna of the Cape Region. This appears to be the extreme northern limit of distribution of this remarkable fauna. Woodpeckers and cardinals, peculiar to the region south were especially attractive. The former make their nest- ing holes in the trunks of the giant cactus. The cardinal's song did not appear to differ from that of the familiar bird of the middle west although this one is a different species. Among the reptiles collected there were several specimens of a desert iguana which is an excessively rapid runner. In action the tail is folded upward, the front legs placed close beside the body and the hind legs only are used. Messrs. Anthony, Tose and Hinkley secured some more desirable birds and another jack rabbit. Insects were very scarce but we secured a few species. The climate at Magdalena is very uniform throughout the year. The nights are cool, the days hot. A breeze usually blows on the water in the afternoon but inland that part of the day is uncomfortably warm. Rain seldom falls, sometimes 256 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. only at intervals of years. Far to the eastward over the Gulf of California, black clouds with flashes of lightning were plainly visible at night. At the so-called "ranch" one family lived in a shed with brush roof, no walls, doors or stove. They had a small patch cleared of brush where watermelons, tomatoes, and date palms were growing with practically no attention. Water was avail- able at about 15 feet depth and was used for household pur- poses but we found it to be too salty to satisfy our thirsts. The ranch is in a valley of about 10 square miles densely grown with brush, small trees and giant cactus. Undoubtedly there is fairly fresh water at a moderate depth over the entire area. It would seem that farming could be more extensively prosecuted if there was a market for the product. July 29 proved to be an excellent day for collecting. Messrs. Cuesta-Terron, Slevin, Gallegos, Tose, Barnhart, Hinkley, Anthony, Captain Angulo and I went across the isthmus to the ranch, the Captain being the pilot of one of the auto trucks left behind by the magnesite company. He proved his ability as a navigator on land as well as on the sea. Considerable time was spent in the giant cactus forest where we found ripe fruit as large as a medium sized orange and with a flavor similar to a raspberry. They were delicious eating and were very effective in allaying the thirst the unini- tiated always experiences in a hot desert afternoon. Many birds were found in this forest, the most important for us being the Cape Region species. The woodpeckers were evidently very fond of the cactus fruit and many ospreys had selected these strange trees for nesting sites. Some of the bulky structures had become so heavy through years of addi- tions that the trees had collapsed. ^^ The rank desert vegetation of the vicinity of the "ranch" enabled us to secure some attractive insects, and two species of land shells (Bulimulus and Micrarionta) were common. Mr. Slevin made very important additions to the reptile collection, one being a rattlesnake not previously known from this island. Another specimen of the jack rabbit was taken, this making "See figures in Nat. Gcog. Mag., Vol. 44, No. 1, July, 1923, pp. 90, 91. Vol. XIV] HANNA— EXPEDITION TO GUADALUPE ISLAND 257 the third for our party, and the Mexican naturalists have taken one. On the morning of July 30 we ran the line of traps at the first break of day in hopes of getting to our specimens before the ants, but we were unsuccessful. The voracious insects had completely spoiled several otherwise valuable specimens ; all we could do was to preserve them in alcohol. The ants are noc- turnal in most of the places in which we have trapped this season and an animal is no sooner caught than it is attacked. In spite of this difficulty Santa Margarita Island furnished us with several specimens of very rare desert mice. It was with reluctance that we left this anchorage at nine a. m. and started northward on the journey back to San Diego. At one p. m. of July 31 we anchored behind the point of land known as Abreojos (eyes open). On the way north we followed the shore sufficiently close so that we would have discovered any herd of elephant seals or other conspicuous animals which might have been hauled out. It was in one of the long bights of this shore line that Dr. C. H. Townsend col- lected several elephant seals for the National Museum about 1888. Messrs. Anthony, Gallegos, Slevin, Barnhart and I went ashore for collecting, the landing being made at two shacks used in other seasons by spiny lobster fishermen. Many turtle bones, lobster carcasses and mollusks were drifted upon the beach. I could not help but regret that equipment was not available to dredge the ocean bottom because it was here that Henry Hemphill had made a very extensive collection of shells many years ago. Numerous species taken there by him have not been found elsewhere. The most conspicuous shells on the beach were the pismo clam. It is prophesied that here will be an important fishery for this mollusk at some future date. A burro trail with fresh tracks led to the northeast to an- other lobster camp toward San Ignacio lagoon. Mr. Anthony stated that the plain back of this point is one of the few remaining ranges of the pronghorn antelope. A fairly fresh horn was picked up near the camp, so the species is probably not yet exterminated. 258 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. No land snails could be found in the limited time devoted to the search. An examination was made of the geological structure out- cropping on the shore at the first point northeast of the usual a.nchorage. Here for about 1000 feet there was an exposure of hard sandstone and shale, dipping southwest at an angle of about 15°. Above, and unconformably upon that series is an even greater thickness of heavy conglomerate which weathers slowly and forms rocky projecting reefs upon which grow the great kelp gardens of the point. Above the conglomerate late Pleistocene sediments rest with great angular unconformity. The shells, however, were not well preserved. Fishes were ex- ceedingly abundant about the point. We arrived at Asuncion Island on August 1 at eleven a. m. and the anchor had scarcely been dropped when some one of the crew caught a "jewfish" weighing about 150 pounds. Later one was taken which weighed nearly 400 pounds. Several bonito were taken on the troll before we arrived. Most of the party went ashore soon after arrival. Messrs. Anthony, Cuesta-Terron and I examined all shores carefully for fur seals but found none. At the same time I estimated each group of California sea lions as we passed. The figures of course were hurriedly arrived at but the total, males, fe- males and young, was close to 4000 animals.'® To this, as an integral part of this rookery, should be added about 1000, subsequently found on Angulo Rock near by. All of the beaches were lined with the animals and they kept up an inces- sant roar with their barking. Harems seemed to contain from 15 to 18 cows and the young pups were learning to swim in the tide pools. Many of the bulls were badly scarred from fighting, a condition which would largely disappear if some of the surplus males could be eliminated. This species was found to be very abundant on most of the favorable breeding grounds south of the Mexican Boundary. There are likewise large rookeries off the coast of California. Certainly the species has sufficiently recovered from its early persecution for the surplus males to be taken for commercial purposes. The skins arc large, uniform in thickness, and make >« See figures in Nat. Geog. Mag., Vol. 44, No. 1, July, 1923, pp. 85, 86. Vol. XIV] HANNA— EXPEDITION TO GUADALUPE ISLAND 259 excellent leather. The fat and flesh make an oil and animal meal of a quality which is equal to, or better than, the average derived from whales. The manner in which the commercialization of such a species can be undertaken without exposing it to unlimited slaughter is a problem difficult indeed to solve. Permits or concessions might be granted to private parties by Mexico and California, limiting the catch to males only and the number to be specified by proper authorities after investigation. While this method of operation looks practicable at first glance it apparently never works out to any other conclusion than the commercial exter- mination of the species concerned. It has been tried repeatedly in many different countries and has always failed to perpetuate the species in the same abundance with which the work was started. Another plan of operation, often suggested and tried is to permit unrestricted slaughter by all persons during an open season. This likewise almost always fails in the perpetuation of a marine species in its original abundance and there are few successes with land animals. The reason is not hard to find. When such slaughter begins large catches are made with ease but as more people engage in the enterprise and the num- ber of individuals of the species hunted becomes smaller, in- creased efforts must be expended to get a profitable catch. These efforts are of two classes ; ( 1 ) political activity such as the securing of longer open seasons, and fewer restrictions, bribing of enforcement officials, etc.; and (2) increased effi- ciency of hunters. One of the most difficult of all classes of beneficial legisla- tion to secure is a measure to more adequately conserve or per- petuate a wild species which is being commercially exploited. Practically never are commercial interests willing to submit to protective restrictions until the species with which they are concerned is approaching industrial extinction. Therefore, the time to provide and apply protective measures is when the species is still abundant and not exploited. In the case of the California sea lions I think absolute prohi- bition of any slaughter whatsoever should be maintained by Mexico in its territorial limits as well as on the high seas. 2^0 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. The same should be done by California and the United States. While this is in force a treaty should be made between the two countries whereby no killing would ever be permitted except on land and by duly authorized agents of the respective governments. In this manner the Fish and Game Commissions of the two countries could develop a market for the amount of surplus available and for that only. Revenues of course would pass to the governments. Objection to this method of operation is possible because it may suggest certain doctrines of socialism, but it has been tried and found successful, whereas no other method ever has succeeded in conserving a species of marine mammal. On Asuncion Island Mr. Slevin took 30 specimens of one species of lizard; no others appear to live there. Land shells were scarce and semifossilized ; no live ones were found. In- sects also were very rare but we succeeded in finding six species. The island is a vast roosting place for birds, but few species breed. Brandt's cormorant is the most abundant of the latter and these form black, close, compact "islands" on the level stretches of white sand. Each mass contains a thousand or more birds. This close association seems to be for the purpose of protection from the gulls because, ordinarily, these did not molest the shags at all. But if we disturbed the "island" colony at all, causing the parents to desert young or eggs, the gulls flocked down in great numbers, breaking eggs and killing young indiscriminately. After we learned this we endeavored to cause as little disturbance in the island routine as possible. The Brandt's cormorant builds its nest of marine algae and the structures are low and filthy. The Farallon cormorant, which is common on the higher land, builds its nest of sticks and lines it with quill feathers. Some of the nests were built in the low trampled bushes of the island; others were placed in the open and raised to a height of three feet." A few pairs of brown pelicans nest on the island, but it is chiefly a roosting place for hundreds of thousands of these birds. " See figures in Nat. Geog. Mag., Vol. 44, No. 1, July, 1923, pp. 92. 93. Vol. XIV] HANNA— EXPEDITION TO GUADALUPE ISLAND 261 The western gull nests in small numbers and there were burrows of Cassin's auklet or some shearwater everywhere where there was soil. These holes were unoccupied. Both species of cormorants and the pelicans had fairly fresh eggs, newly hatched young and young ready to fly, so the nesting season must be greatly prolonged. Frazer's oystercatchers and black turnstones were fairly common and in the late evening a few Heermann's gulls flew in. The vicinity of Asuncion Island is wonderfully rich in ma- rine life. A huge jelly fish, vivid magenta in color, and with streamers 20 feet long was abundant. South of the island 20 miles there was a sudden lowering of the temperature of the sea water to 61° F., 13° colder than outside Magdalena Bay. The cold water probably accounts for the abundance of sea life, at least in part. A short distance northwest of Asuncion Island there is a flat-topped rock 50 feet high on which we collected eight species of beetles in less than an hour. The rock is very con- spicuous as the island is approached from the south. Because of the different species of insects from those found on Asun- cion, a name for this rock is needed and we proposed to honor it with the name of our congenial captain, Victor Angulo. Geologically, Asuncion Island is composed almost entirely of Jurassic Franciscan Chert, or a chert which is very similar to this widespread and well known fomiation in California. On the north side there appeared to be some metamorphism. The island, like so many other places in the region, has been subjected to a comparatively recent short submergence and subsequent elevation to about 25 feet. Traps were put out in the evening and next morning they contained 14 specimens of Peromyscus. On Aug^ist 2 we left Asuncion Island at six a. m. and went ashore on San Roque Island at seven-thirty a. m. It is similar in almost every way to Asuncion but is only about 65 feet high. The steamer San Jose went on the rocks here in 1921 and there was a great deal of wreckage strewn about. The hull was firmly wedged between the rocks. September 5, 1925 252 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Brandt's cormorants were found in enormous numbers but the only nests of the Farallon species were around the shores on piles of driftwood. About 1,000 Heermann's gTills were perched on one rock ; very few young were among them. Several hair seals were seen in the water in the bight on the south side of the island but all efforts to secure specimens failed. Field mice were abundant but we took none during our short stay. No land shells were found and only three species of beetles were taken. We left San Roque at eleven a. m. and anchored in the north end of San Bartolome (Turtle) Bay at six p. m. Messrs. Anthony, Tose, Slevin and I went ashore with a lantern after dark. Traps were put out and in a bunch of sagebrush we found a rattlesnake which Mr. Slevin promptly shot. The low sea cliff at the landing consisted of sandstones dip- ping to the westward. Several species of fossils were collected which later showed the age of the rocks to be Pliocene. Two Peromyscus were found in the traps next morning (August 3) and we left San Bartolome Bay at six-thirty a. m. It was an exceedingly attractive place to work but our mission was insular and we could not stay. At nine a. m. we went ashore on the south end of Natividad Island, where the entire party worked all day. This is another bird island par excellence. Gulls, shearwaters and cormorants nest on the highest parts. Many pelicans were seen resting but none seemed to nest. The Brandt's cormoranis form "islands" on the level stretches near shore, while the Far- allon species goes to the higher interior and builds nests as on Asuncion Island. Of land birds we saw only desert sparrows, ravens and duck hawks. The latter nest on the island in very accessible places; a person could walk directly to some of the nests. The island is tunneled with the burrows of black-vented shearwaters. About 40 of these burrows were excavated and five birds were thus secured. One was a young of the year, the others adult. Apparently the birds continued to visit their burrows long after the nesting work was done. About eight species of insects were secured. Dead land shells (Micrarionta) Vol. XIV] HANNA— EXPEDITION TO GUADALUPE ISLAND 263 were everywhere in abundance but not a live one could be found. Mr. Slevin took two species of lizards. Geologically the island is very old. Shales and sandstones in- clined from 0° to 75°, extend from the south end northward at least four miles. No fossils were found and the age was not definitely determinable but the sediments are certainly older than Tertiary. The island has been subjected to a recent sub- mergence down to at least 100 feet. It was then elevated before any considerable quantity of sediment could accumulate. Six species of cactus were seen, the most conspicuous being the long shafts of the group commonly called giant cactus. Shrubbery was very scarce but there was abundant evidence to show that when there is rain a quick and luxuriant growth of succulent plants follows quickly. All were dead and parched when we were there. On August 4 the traps on Natividad Island were found to contain 1 1 Peromyscus. Many of the traps had been sprung by ravens and gulls. Those most successful were set about some bushes which contained very filthy cormorants' nests; there were numerous mouse-burrows under the nests. Some speci- mens were also taken in the traps set in shearwater burrows, these seemingly forming a haven for mice and lizards as well as birds. We left Natividad Island soon after daylight and arrived again at Bernstein's abalone plant on Cedros Island at nine a. m. Everyone was glad to get ashore here for various rea- sons, chiefly because of the abundance of freshwater. The party divided in various directions. Mr. Slevin and I visited the spring from which the water supply is derived and secured more detailed observations on this little oasis. It is situated on the crest of a ridge between 2,000 and 3,000 feet high and an area of two or three acres is overgrown with rank vegetation. Cedar trees and elephant trees grow around the margin and some of the grass is 10 feet high. Many strange plants and insects were collected. Birds were not common and were excessively wild. Where the water first flows out it is delicious but as it flows down the canon to the reservoir intake of the pipe line it passes through a mineralized belt and takes up a considerable amount of this. 254 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. If the pipe were extended to the spring itself a much larger and better supply of water would be obtained. (See pi. 18, %.2.) Our complete line of traps put out late in the evening did not contain a single mammal on the morning of August 5. Signs of Perognathus were abundant but the animals consistently avoided any bait we offered. We went after them with pick and shovel on the 5th and succeeded in capturing one. In the afternoon I put some traps out in a cafion about two miles above the camp where the only sign of woodrats had been found on this end of the island. In setting the line I found a rattlesnake in a hole under a bank and Mr. Slevin came to my aid with his trusty pistol. It turned out to be Crotalus exsul the type locality of which is Cedros Island. A good series of fossils from the Pliocene beds south of the camp was obtained during the day. On August 6 we found our traps had caught one woodrat and three Peromyscus. One more of the latter was taken dur- ing the day. Messrs. Tose and Hinkley visited the spring and secured several birds. They also took one cottontail rabbit, a few of which had previously been taken there by some of us. Mr. Slevin and I went almost to the top of Mt. Cedros north- west of the camp. Stunted cedars are scattered over the upper 1 ,000 feet of the mountain and cactus was common there. No deer were seen but we came across a small herd of goats. For some reason these animals have not increased as they did on Guadalupe. The elephant trees grow to the very top of the island and some of them, long cut away, indicated a trail. The bark of the tree is white or buff and peels off like a paper birch. The outer layer is very thin ; this is followed by a green layer, also very thin; and that in turn by a pulpy part about one inch thick. When the bark is punctured a thick, sticky, cream-like liquid exudes in considerable quantities at the season of our visit. (See pi. 19, fig. 1.) In the early morning of August 7 the ship was moved to the mouth of Grand Canon, about the middle of the eastern shore and collections were made throughout the day. Three male deer were shot and carried to the beach. The animals are here very common, tame and unafraid. One was Vol. XIV] HANN A— EXPEDITION TO GUADALUPE ISLAND 265 taken with the .22 cahber rifle. Trails were well beaten from the shore to the highest point. In this valley there are some fine groves of elephant trees, the largest seen thus far. The cedars are found from a little above sea level to the top of the mountains but they are small and stunted. No trees comparable to those 12 inches in diame- ter at Bernstein's spring, were found. Messrs. Slevin, Anthony, the Chief Engineer of the Tecate and I went to the top of the Pine Ridge on the north side of the canon. This was photographed by Dr. Townsend'^ from the bottom of the caiion and the pine trees standing soldier-like on the rim were mistaken for "cedars." (See pi. 18, fig. 1.) He mentioned "one spring" in the canon but every branch canon we explored had one or more. In some there was water in considerable amount but no place was the vegetation as rank as about the one from which Messrs. Bernstein get their water. Above one spring there were the stone walls of an old cabin, long ago abandoned. Some assayer's supplies near by indi- cated that it may have been a camp of a prospecting party. On the morning of August 8 our traps contained only one woodrat, two Peromyscus and one Perognathus. Captain An- gulo, the Chief Engineer and I went up the canon again in search of deer and succeeded in getting a female for the collec- tion. This species of deer is found only on Cedros Island and was reported extinct at one time. There were no specimens of it in any western museum prior to our visit, so, in view of the abundance of the species, we felt justified in taking four. The doe taken today was prepared for the National Museum of Mexico. In view of the fact that the Cedros Island deer has been reduced in numbers, at least once, to the verge of extinction through the activities of hunters and the likelihood of the same being rei>eated whenever people in large numbers visit that region, the Mexican naturalists on the expedition, Messrs. Cuesta-Terron and Gallegos, determined to make recommenda- tions to their government for some means of protection of the species. Accordingly, upon their return, the situation was ex- plained to the Secretary of Agriculture and Public Works and 18 Bull. Am. Mus. Nat. Hist., Vol. 35, 1916, p. 411, fig. 9. 256 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. on May 28, 1923, the killing of this deer was prohibited from June 1, 1923, to May 31, 1928, through the issuance of a proclamation by the President of Mexico. Since this action was taken as a direct result of investiga- tions made by this expedition, the text of the proclamation is herewith quoted in full, the translation into English from the Spanish having been made by Miss M. E. McLellan of the California Academy of Sciences. SUBJECT PROCLAMATION PROHIBITING THE KILLING OF CEDROS ISLAND DEER Alvaro Obregon, Constitutional President of the United States of Mexico, considering that, owing to the excessive hunting of the deer (Odocoilcus cerroensis \^cerrosensis']), the species has greatly diminished on the island of Cedros, situated on the western coast of Lower Cali- fornia, of which reproduction is necessary in order that it does not become extinct, in exercising the power which is conceded to me in clause I of article 89 of the Federal Constitution, and with a basis of the articles 51 in the clause III of the law of the first of October of 1894 and 50 of the law of the twenty-first of December of 1909, I have held well to promul- gate the following REGULATING ORDINANCES WHICH ESTABLISH THE PROHIBITION OF THE HUNTING OF THE Yi'EER (ODOCOILEUS CERROENSIS [CERROSENSIS]) ON THE ISLAND OF CEDROS. Article 1. — It is prohibited for five years, beginning with the first day of June next, to hunt, capture, kill, or injure in any way whatever the deer (Odocoilcus cerroensis Icerroscnsisl) on the island of Cedros, sit- uated on the western coast of Lower California. Article 2. — The prohibition includes the distribution or sale of the prod- ucts originating in the animals referred to in the preceding article. Article 3. — It will be considered as proof of the infraction of the fore- going article, the use of anything that alters the products of the deer, change of name, or the employment of any other means of deceit. Article 4. — The violation of the preceding ordinances will be punished by a fine from $50.00 to $500.00, which not being paid, will be commuted to fifteen days imprisonment, and which will be imposed by the Bureau of Agriculture and Public Works or its Agent Generals. Article 5. — The repetition will be punished by the penalty which, depend- ing upon circumstances, should have been imposed for the last offence committed, with an addition to the fine : 1. — To one sixth part, if the offence shall be less than the former. 2. — To a quarter part, if both shall be of equal gravity. 3. — To one third part, if the last shall be more serious than the pre- ceding. Vol. XIV] HANNA— EXPEDITION TO GUADALUPE ISLAND 267 4.— If the former fine shall have been remitted or the repetition shall not be the first, the amount may be double of that related to tne previous infractions. Article 6. — The act shall be considered a repetition when the culprit has been condemned on a former occasion for an offense of the same kind within the six months previous to the last. Article 7. — For the imposition of the penalty, there will be considered as accomplices all the persons who by whatsoever means participate in the infractions of the ordinances contained in articles 1 to 3. Article 8.— Because the Agent Generals of the Bureau of Agriculture and Public Works, imposes the penalties which are mentioned in the pre- ceding articles, they will draw up the related report and transmit a copy of it to the said Bureau. Article 9. — The fines which are imposed in accordance with the regula- tions contained in the foregoing articles, will be made effective for the management of the Federal Tax Office, exercising, on its part, the eco- nomic-co-operative power determined by the Fiscal Law. Article 10. — In all cases of the imposition of penalties, the animals cap- tured or killed shall be seized, also the weapons, ammunition, and hunting equipment which are found in the possession of the offenders. Article 11.— If the animals seized be alive, they shall be returned to the place in which they were taken, and if they be dead, they shall be suitably disposed of. The weapons, ammunition, and equipment seized shall be disposed of by the said Federal Tax Office, except in the cases in which the Bureau of Agriculture and Public Works decides to use them.

After lunch the ship was moved to the north end of the island where an extensive mining- camp was once located. Three old buildings and the remnants of a wharf were still standing near the beach although they had not been utilized for about 25 years. Several burros greeted us upon our arrival. They apparently still had memories of their human associations. Messrs. Tose and Hinkley worked up the caiion toward the old mine and, with the exercise of the greatest care succeded in getting only one bird, a Say's flycatcher. This is a fair commentary on the scarcity and wildness of the birds of Cedros. There must be a reason for this situation but, try as we would, we could not learn what it was. 258 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Fishes were excessively abundant and several large jewfish were hooked at the anchorage.^® Sardines formed a zone for half a mile out to sea. Mr. Anthony saw schools of yellow- tailed tuna 100 yards wide and half a mile long, and inshore numerous small "halibut" were caught "jumping" from the water. Out in a boat over the rocks and kelp gardens it was bewildering to watch the constant struggle for existence among the living things. When a tuna or barracuda entered the shoals of smaller fishes pandemonium reigned for several minutes. The sardines are preyed upon from below by many fishes and above by the birds. Their existence must be one adventure after another. From the observations thus far made it appears that the greater part of Cedros Island is composed largely of Jurassic sediments — Franciscan cherts, sandstones, and in one place in Grand Cafion, conglomerate. Much alteration and metamor- phism has taken place and from the excessive amount of frac- turing it appears to be on or near a fault zone. At the south- western corner of the island there has been some volcanism and at the north end the land is e^reatlv disturbed with intru- sions of serpentine. On the eastern side there are Pliocene sediments at one and probably two points. On August 9 Messrs. Anthony, Slevin and I went up a cafion south of the landing to the top of Gill Peak, thence north down the mountain side through a pine forest to the old mine. From the top of the mountain we could see the western shore of the island with its extensive outlying kelp beds. This was the habitat of numerous sea otters about 100 years ago but if any are left they are very scarce. We saw none nor did we hear any reports of any. Except for the work we did later on the southwest side of the island the western shore is unex- plored, biologically. Extensive operations have been undertaken at the old mine. About 20 buildings and much of the machinery remain on the ground. The ore is a white rock said to have been rather rich in copper and gold. Large quantities were shipped from the mine to San Diego for smelting but this form of operation did not pay. We could not investigate the underground workings i»See Nat. Geog. Mag., \'ol. 44, No. 1, July, 1923. p. 83. Vol. XIV] HANNA— EXPEDITION TO GUADALUPE ISLAND 269 because of caving at the entrance. The ore on the dump was leached and the stream bed below was blue green in color. In operation the ore was hauled in carts down the steep canon bottom to the wharf. A cobblestone road was built in the creek bed at great expense but it has almost completely washed out. Pipe lines are mostly rusted out and the entire plant is in an advanced state of decay. A visit to such a place makes one sad to think of the great amount of toil and money used and hard- ship endured for naught. It is a graveyard of human effort. Messrs. Tose and Hinkley saw four more deer during the day but did not take any of them. On our trip to Gill Peak we saw only abundant signs of the animals. During this entire trip of about seven hours' duration we saw four land birds and four only. These were three wrens and a shrike. Late in the evening Mr. Anthony and I visited the sea-lion rookery at the north end and estimated the number of animals at approximately 1000. Harems had completely broken up and the herd was hauled on the beaches away from the rookery ground. We wanted to be sure no fur seals had hauled out here near the sea lions. On the way back we were greatly im- pressed by the inconceivable numbers of fishes in these clear waters. On the morning of August 10 Messrs. Tose and Hinkley returned to the ship after a cold night spent sleeping in the hills. They wanted to be out late in the evening and at daylight in the morning in hopes of securing specimens which otherwise are unobtainable, particularly birds, but little success attended their commendable efforts. They did bring back another male deer. At seven-thirty a. m. we left the mine anchorage and re- turned again to Bernstein's camp. His launch, the Marian, had been there the day before and left supplies for the Tecate. At anchor we found the auxiliary schooner, Gipsy Girl, from San Pedro, California, with Captain Farnsworth, Mr. Peabody and Dr. Spencer on board. We left the anchorage the same day and stopped for the night at the west end of South Bay, too late to explore much. 270 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Traps were put out, however, and next morning, August 11, they contained six Peromyscus and one Perognathus. At six a. m. we sailed around the southwest corner of Cedros to the abalone collecting station maintained by Bernstein Brothers. The station is on the southwest peninsula in the protection of some off shore projections called "Red Rocks." Messrs. Tose, Hinkley and Slevin went ashore collecting at eight a. m. After tramping all day and until five p. m. that evening, the ornithologists came back with the news that they had found a skull of an elephant seal on the beach. This was an interesting record as it showed something of the former distribution of the species. After nine hours of search the same men saw only one land bird, a wren. Mr. Slevin took 57 lizards representing only two sj^jecies. Messrs. Cuesta-Terron, Gonzales, Angulo, Anthony and I visited the abalone divers at work in the kelp and examined the red rocks at close range. The outer one had 50, the inner 250 California sea lions, but no fur seals. Both islands are low and the surf breaks over them in storms. One of the men at the camp had killed a female deer that morning and he gave us the skin and skull. He also gave us two other skins, a pair of fine buck horns and a good skull of a porpoise. We ate lunch on shore at the camp and at two p. m. I went down in one of the diver's outfits in 24 feet of water. It was the most marvelous sight I have ever seen. The sensation ex- perienced of mioving about among the fishes, the star fishes, the anemones and the giant swaying fronds of seaweed is inde- scribable. Purple coraline algae covers much of the rocky bot- tom at this point and against it as a background the golden garibaldis looked like gems. Many other fishes swam about and inspected me from all angles. It was rather disconcerting to have them stare into the helmet at me. Abalones were very common but they carried so many other things about, growing commensually on their shells, that they were difficult to see at first. The diver in operation prys them loose with a bar and puts them in an iron basket to be hauled to the surface. These men stay down for four hours at a time but I found it very fatiguing after a few minutes. Vol. XIV] HANN A— EXPEDITION TO GUADALUPE ISLAND 271 The country in the vicinity of this camp is exceedingly barren and dry.^" There is very little vegetation of any kind. One of the men told us there was a third giant cactus tree on the west side of Cedros Mountain in addition to the two found by Mr. Slevin and me on the south side. This may be of in- terest to botanists because the species would very likely be over- looked on casual inspection of the island, yet it is a definite resident. The two individuals we examined were about 1 5 feet high. During our stay on Cedros Island we did not see any of the do2:s which are said to have g-one wild on the island. Cats are said also to be found in the hills, and the people at Bernstein's main camp had a gentle young kitten which they said had come to them two months previously. At seven a. m. of August 12 we left the abalone station at Red Rocks after taking up the traps and the six wild mice they contained. The ship was taken to the harbor on West Benito Island, where we went ashore at nine-thirty a. m. Messrs. Cuesta-Terron, Anthony and I spent the rest of the forenoon surv^eying the shores for fur seals but we found none. It has been reported that these animals may have been on the San Benito Islands since they were exterminated on Guadalupe. Mr. Rufus A. Coleman, a member of the California Academy of Sciences, visited West Benito in 1916 with the steamer Albatross and saw some animals which he thought possibly may have been fur seals. We found only about 150 California sea lions on the rookery ground. On the beach opposite the landing we found many bones of elephant seals and four fairly good skulls were saved. Our cook on the Tecatc stated that he was on West Benito six months in 1918 in a lobster camp and saw two elephant seals on the same beach. About the same time six were found on the southeast corner of East Benito, one of which he shot. The islands were probably used only for a hauling ground and the presence of these remains here, on Cedros Island, and the ani- mals found in 1888 at San Cristobal Bay, may furnish a clue as to the migration of the species from Guadalupe. Miss M. E. McLellan has called attention to the belief of some naturalists^^ '" See figure in Nat. Geog. Magazine, Vol. 44, No. 1, July, 1923, p. 90. " See Anthony, Journ. Mammalogy, Vol. 5, No. 3, 1924, p. 149. 272 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. that the elephant seal of Chile and Guadalupe are one and the same species. While statements of Harris and Rothschild^^ cannot as yet be definitely disproved it is doubtful if the north- ern animal can cross the equator twice each year and still be where the records show it to have been on certain dates. The two groups may be the same species but I doubt if they are part of the same herd and if they ever associate together. The afternoon of August 12 was spent in general collecting. Least, black and Soccoro petrels were taken from burrows and in rock slides. (See pi. 17, fig. 3.) Some fresh eggs were found. A specimen of McGregor's house finch, confined to the San Benitos, was one of the very desirable species of birds taken. San Benito sparrows were common. Land shells ( Micrarionta pandorcs) were living in abundance in the rock slides and a sufficient number was taken to study the excessive variation of the species. House cats have gone wild on this island as on most of the others visited. On West Benito there was a camp for the collection and dry- ing of abalones ; it was owned by a Japanese who had a con- cession for the work. Large quantities of "meats" were on the frames drying and the methods employed were essentially the same as those already described. All fuel and freshwater has to be brought from San Diego as there is none of either on the San Benitos." No signs of mice or rats were seen on West Benito Island but lizards belonging to one species were common. In the early morning light of August 13 Messrs. Slevin, Anthony and I rowed to Middle Benito Island for two hours' collecting. No land shells were found but many desirable beetles were collected. San Benito sparrows and a duck hawk were collected. Least, Socorro and black petrels and western gulls nest on the island. Cats are apparently very abundant if we may judge by the remains of petrels about the burrows. A great many elephant seals and sea lions have been killed on the ^^ Rothschild, Notes on Sea Elephants (Novitates Zoologicse, Vol. 17, 1910, pp. 445. 446). ^ See figure in Nat. Geog.

No mice or rats were found on the island but there were small lizards belonging- to the genus Uta. After breakfast the ship was moved to East Benito and 4 J/2 hours were spent in shore collecting. Land shells of the Micra- rionta group were abundant and I found another species be- longing to the family Pupillidse not previously known from the islands. It was found only in one rock pile on the east side of the island. San Benito sparrows were collected and I took a mummi- fied hermit thrush from the thorns of a "cholla." One house finch was seen. That species is now practicaly extinct and it is somewhat doubtful if any other field collector will ever see it alive. If the absence of the birds was due to migration then the distinctness of the form might well be questioned. Pelicans nest on the east side of the island and Brandt's cormorants on the west. About 1,000 California sea lions were found on the east side in the "fiords." Mr. Slevin took lizards belonging to the genus Uta on this island. On East Benito Island I had the interesting experience of being stung on the knee by a scorpion, and thus an opportunity was afforded to test the "deadliness" of this arachnid. The sensation was about that of being stung by a honey bee but the pain did not last as long. A slight but tem- porary swelling resulted and the spot was red for perhaps a week. An hour after the sting the wound would never have been noticed except for a slight itching which was noticeable for fully a month afterwards. There is some evidence of house mice on East Benito ; many small land shells were broken open in a manner similar to those on Guadalupe, the work there having been attributed to the mice. Cats were also abundant on East Benito and they were wreaking havoc among the petrels. The three San Benito Islands are small and close together in an east- west line. The westernmost one is about 661 feet high and is composed largely of Franciscan chert of Jurassic age, beautifully contorted and laminated. There has been some 274 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. metamorphism of the sediments on the south side.^* The Mid- dle Island, the smallest of the three, is composed entirely of chert. East Benito is high and rugged and largely metamor- phic. Schist, marble and quartz are abundant rocks. Only the tops of the three conspicuous hills disclose the Franciscan chert formation. All of the islands show the Pleistocene submer- gence and subsequent uplift. They were not down long because the sediments deposited are very superficial. The eastern island seems to have been down the shortest time and the fiord forma- tion of the shore line indicates that it was not elevated to the original level again. Most of the available shore lines of the islands were occu- pied by California sea Hons.^* We left East Benito Island at two p. m. for San Quintin Bay. A brisk northerly wind and heavy swell held us back all afternoon and the following night. We arrived at San Quintin at noon of August 14 and hur- riedly took on fuel. This being completed at two-thirty p. m. we left at once for San Martin Island, near the entrance of the bay. It was five-thirty p. m. before we were safely anchored but all of the party hurried ashore to collect as much as possible before darkness overtook us. The main part of the island is volcanic, and densely covered with cactus, brush and huge blocks of lava. Caves and blow- holes are everywhere and at the top there is a crater. Several species of plants are found only on this island, one being a magnificent Dudleya waist high. The deep cavities and crevices are occupied by numerous woodrats with black feet. The Japanese in the past have at- tempted to destroy these rodents, first by introducing cats then by burning the brush systematically but neither course proved effective. The cats appear to live on birds and beach debris. A frame house in good condition was formerly occupied by a Japanese abalone camp but was empty at the time of our visit. Net racks close by were being used by the purse seiners to re- pair their fishing gear. Three of their boats anchored in the little cove where we were for the night. They were manned by Austrians. *♦ See figures in Nat. Geog. Mag., Vol. 44, No. 1, July, 1923, pp. 86, 87. Vol. XIV] HANKA— EXPEDITION TO GUADALUPE ISLAND 275 I succeeded in finding four or five species of land snails on the island and Mr. Tose collected a rock wren, which has been described as a distinct subspecies. A snake was seen among- the great lava blocks but it could not be captured, much to the regret of Mr. Slevin ; no species had ever been collected on San Martin. At seven p. m. the boats were hoisted and we sailed for En- senada. This we reached at nine a. m, of August 15. The day in port was largely spent in packing collections and equipment and making general preparations to disembark next day at San Diego. This we did at nine a. m. when the expedition came to its logical end. PROC. CAL. ACAD. SCI., 4th Series, Vol. XIV, No. 12 HANNAI Plate 15 Fig. 1.

ANTHONY The "Tecate" sailed from San Diego, July 9, touching at Ensenada the same day to pick up several of the Mexican members of the party. From that port it sailed direct to Guadalupe Island which was circumnavigated. A week was devoted to that island, including- two trips to the top and pine belt at the north end. From Guadalupe the vessel returned for fuel to San Quintin, where three days were spent making investigations before proceeding to Magdalena Bay and return, touching at all the coast islands en route with the exception of San Geronimo, as well as collecting to a limited extent at several mainland points. The expedition returned to San Diego, August 16, having sailed over 1,400 miles. Owing to the season, the collections of birds were quite un- satisfactory, all species being in moulting condition. How- ever, the expedition served as a reconnoissance to enable us to plan for further work in the future. As there have been but few papers treating of the insular life of Lower California, a brief sketch of the islands in their relation to the mainland may be of interest. With the excep- tion of Guadalupe, all the islands of that part of the coast have ^ This is paper No. 2 of the Tecate Expedition. No. 1, the Narrative, gives a com- plete itinerary. See this volume, pp. 217-275. September 5, 1925 273 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. at some time been a part of the mainland. All but the above exception lie at no great distance off shore and the water be- tween is of a depth indicating a somewhat recent separation. At all points from San Quintin south to Magdalena Bay, in- cluding both islands and mainland, is found abundant evidence of a recent uprising of from 20 to 30 feet above the present sea level. In his pai:>er on the geology of this section. Dr. Hanna will treat this subject in full. Land mammals are found on all of the islands with the ex- ception of Guadalupe and the Benitos. The first mentioned has neither reptiles nor mammals, except introduced mice, goats and cats, while the Benitos boast one species of lizard. Cedros, lying 15 miles from nearest points of the mainland, is the largest island, save those bordering Magdalena Bay on the west, which are so nearly a part of the mainland as to bar them from the brotherhood of islands. Viscaino, in 1602, visited Cedros, and he, with other explorers of this early day, men- tions rabbits as "black as jet with fur softer than a beaver's." They must have been well bleached since that day, and have been ever since I have known them. Some of the early Spanish explorers also credit Cedros with a considerable population of "bold Indians." So far as present records go, there is no evi- dence of this or other coast islands south of the Coronados ever having been inhabited by Indians. At an early date a coast whaler left goats on Guadalupe and Cedros, with the evident intent of securing a supply of fresh meat. Though Cedros seems to be better suited than Gua- dalupe for the requirements of a reasonable goat, they never seem to have become overly abundant on that island. Gua- dalupe, however, has been for many years so overstocked, des- pite the thousands that have been killed, that the entire floral life of the island is doomed. Many species of plants, and some genera peculiar to the island, have been entirely exterminated, and not even a pine, oak or palm can look down upon a seedling to replace the aged trees now beginning to fall. A sprout of any kind is nipped as soon as it is above the soil. It is estimated that a goat census of Guadalupe would show from 30,000 to 50,000 animals. As long ago as 1887. when the present writer first became acquainted with the islands, 15,000 goat skins per Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 279 annum were being exported without causing any noticeable difference in the herds. Since that day, many concessionaires have attempted the business and failed, owing to the slight dif- ference between the cost of skins and the selling price on the mainland. If the goats have been busy in reducing the floral list of the island, the cats that were introduced at some time in the past have lost no time in exterminating the birds. At this date all of the land species have been reduced to no better than ten per cent of their abundance in 1887, and several have entirely dis- appeared. For several years past there have been no records of the Guadalupe Caracara, flicker, towhee or wren (Thryomanes brevicauda) , and they no doubt are totally extinct. Kinglets and crossbills, formerly plentiful in the pines at the north end of the island, were not found by us, and they quite likely belong to the list of those destroyed by cats. The end of all the land species of the islands, with the exception of such as Buteo borealis caliirus, is a matter of but a few years. Within the past 25 years the fishermen of the Lower California coast, chiefly Japanese, have introduced cats on every island north of Magdalena Bay, and the effect is noticeable at this early day. Upon the San Benito Islands, the land birds, abundant but a few years ago, have almost disappeared. At the time I last called at these islands in 1898, one might easily have collected a dozen Carpodacus mcgregori in an hour. In August of the current year, four of our party for two days made this species a special object, with the result that one was secured and another seen. Petrels and other small water birds have also suffered heavily on Guadalupe, and unless there may be some other as yet undiscovered nesting ground of the Guadalupe Petrel it will soon be extinct. The only known colony at the north end of Guadalupe seems to be entirely destroyed. A few birds seem to have been nesting in the cliffs, and if such colonies are sufficiently extensive the species may endure for several years. The present list of birds and mammals is of species seen and mostly collected, but one or two are included on evidence furnished by others ; the source of such data is mentioned in the text. Many species not mentioned are known to occur September 5. 1925 9gQ CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. within the limits of the region covered, but after an absence of a quarter of a century, I am in doubt as to their present status and will leave them for future investigation. List of Species of Birds 1. Ptychoramphus aleuticus, Cassin's Auklet This species was quite common at all seasons as far south as 28 degrees, at least. At the time of our visit, all had abandoned their nesting grounds and were at sea. Nowhere did we see flocks of more than five or six — more often single birds or pairs. Two specimens in badly worn plumage were taken at Guadalupe. 2. Brachyramphus hypoleucus. Xantus's Murrelet This species was in badly worn plumage and several of the birds seen at sea seemed unable to leave the water. They were not uncommon as far south as Magdalena, but none was found on land. In digging for eggs of Oceanodroma at San Benito Island, August 12, a downy 0. monorhis was found in a burrow with an addled tgg of the Murrelet. I have never found this species nesting in a burrow of this nature, the many eggs that I have taken in the past being either among the rocks or under overhanging curtains of thick grass or other vegeta- tion. In either situation, subdued daylight reached the brood- ing bird. I am inclined to think this Murrelet pairs for life, as it is quite the rule to find either a pair of birds or at most two pairs in company. 3. Stercorarius parasiticus. Parasitic Jaeger This species is not uncommon along the coast covered, but is not often seen as early as August. On July 31 three or four were noted south of Abreojos Point, Lat. 26° 40' N. They were not seen again. 4. Larus occidentalis. Western Gull The dominant species of the genus, and the only one nesting at present in the region under discussion. About Guadalupe Island a few were seen. July 11 to 17. with young not yet on Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 281 the wing. There seemed to be only a scattering few gulls about this off-shore island, as not over 10 to 12 pairs were seen at any one spot. On all other islands they are more or less abun- dant as far as Magdalena Bay. Young, but a short time from the tgg, were seen as late as the first of August, and these belated broods may perhaps be due to the rookeries being raided earlier in the season by fishermen, who take the eggs as long as they can be found in an edible condition. 5. Larus heermanni. Heermann's Gull On the voyage south, this species was not seen until we reached San Quintin Bay, July 18, where a dozen in juvenile plumage were noted. They were seen sparingly south to Mag- dalena Bay, and on August 2 at San Roque Island a flock of about 1,000 were met with, mostly immature birds. Formerly there was a nesting colony on this island, but from indications I would say it has been destroyed by the resident fishermen. From notes furnished me by those who have recently visited the nesting grounds of this gull in the Gulf of California, I do not hesitate to state that unless protection is offered at once the species will soon be extinct. Large colonies are still found nesting on the islands to the west of Guaymas, but boats from that port haunt the nesting grounds as long as there is any chance of securing one more tgg, and the tgg that hatched has been the rare exception. A few years ago this was one of our common gulls along the coast of California, as far north as Santa Barbara. At all seasons of the year a few at least might be depended upon to be found along the kelp beds out- side the harbor of San Diego. During the past six years only one has been noted. A few seen on the rocks at La Jolla, fif- teen miles north of San Diego, the past year are all that I have any record of. 6. Xema sabini. Sabine's Gull(?) Off Abreojos Point, July 31, we met with large flocks of shearwaters and elegant terns feeding on the very abundant fry. With the thousands of the above species were several small gulls that filled the requirements for this species better than any other. Owing to their distance from the boat, positive 282 CALIFORXIA ACADEMY OF SCIENCES [Proc. 4th Ser. identification was impossible. We again fell in with 25 or more of the same species off Todos Santos Islands, August 15, under exactly similar conditions. 7. Sterna m.axima. Roval Tern Formerly this species, like the Heermann's Gull, was abun- dant all along the coast of southern and Lower California. They were seen at San Quintin Bay and Cedros Island during our voyage in July and August, but only in very small num- bers. I can only attribute their scarcity to the fact that the fishermen have raided the nesting grounds to such an extent that the species is becoming rare on this coast. 8. Sterna elegans. Elegant Tern The elegant tern was seen at several stations from San Quintin south to Magdalena Bay, but like the royal, there were but few compared to their former abundance. At Abre- ojos Point, however, on July 31. we found a large mixed flock of sea birds feeding on sardines. Ninety-eight per cent of the flock — estimated to be 25,000 birds — was of this species, with young of the year predominating. I have been told that formerly there was a large nesting colony of this species on San Roque or Asuncion Island, but that the constant persecu- tion had driven them away. As all of the islands along this coast for 500 miles are used as permanent fishing camps during the entire nesting season, and as the Japanese and Austrians composing the personnel of these stations depend on eggs for their table, so long as any are to be found, there would seem to be small chance for any of the gulls and terns. If the toll of eggs exacted by the fisherman was the sum total paid, the dam- age might be safely disregarded, but as will be instantly recog- nized by any who have visited an island where gulls are to be found, and terns or cormorants are nesting, the real slaughter begins when man, followed by a cloud of screaming gulls. drives the nesting birds from their eggs or young. The gulls, pouncing down on the undefended nests, destroy eggs or young by thousands, and a frequent disturbance of this nature, even though no eggs are taken by the fishermen, will naturally des- troy the species. Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 283 9. Sterna forsteri, Forster's Tern A few of this species were seen with the last mentioned at Abreojos Point, also a few at San Ouintin Bay on August 14, the vanguard of the fall migration. 10. Sterna antillarum. Least Tern At Abreojos Point there were half a dozen of the least terns fishing in the shallow water inside the surf line. They did not seem to care for the company of the thousands of their larger cousins and the deeper waters. 11. Chlidonias nigra surinamensis. Black Tern One or two of the black terns were seen with the large flock of elegant terns at Abreojos, and a day or two later a few along the kelp beds 100 miles north. This species is not un- common during the fall migrations about the kelp beds of the entire coast, but does not seem to linger long. 12. Diomedea nigripes. Black-footed Albatross This species seems to be far less common along the southern coast than it was 25 years ago. On our cruise to Magdalena Bay none was seen until we neared Guadalupe Island, July 11, when two were picked up at daybreak and followed the ship until we reached the island. They were seen sparingly as far south as between 25° and 26°. Formerly I found the short- tailed albatross (D. alhatriis) equally common and over the same range as nigripes, but none was seen the past summer, nor have I seen during the past two years an albatross of either species between Point Loma and the Coronado Islands, where they were formerly of regular occurrence, though I have visited these islands perhaps 20 times within the time mentioned. The raids made by the Japanese on the nesting colonies between Hawaii and Japan no doubt account for the present scarcity of birds along our coast. 2g4 CALIFORNIA ACADEMY Of SCIENCES [Proc. 4th Ser. 13.

Pink-footed Shearwater This species was found more or less abundant all along the coast and for 50 miles or more at sea. Their presence seemed, as with all of the other shearwaters, to depend entirely on the small fish on which they feed. At several points along the shore flocks of many thousands of shearwaters were seen. Always such flocks were composed of the several species of Puffinus found on this coast, with a sprinkling of gulls, cor- morants and pelicans. 15. Puffinus opisthomelas. Black-vented Shearwater Generally distributed over the entire region covered by the expedition and by far more abundant near Natividad Island, where the largest known nesting colonies are found. On August 4th, Dr. Hanna and the writer opened 25 or more burrows, with the result that four birds were secured, one being a juvenile, showing but little of the natal down, other- wise the plumage was not to be distinguished from the adults. From the tracks about the burrows I think that the birds visited the nests each night, though for what reason after the young had departed, would be hard to say. On a former visit to Natividad, in September, I found fresh tracks about the entrances of the burrows, but did not succeed in taking any birds, though many nests were opened. Fresh eggs in abun- dance have been found in the Natividad colonies in April, the birds beginning to occupy the burrows some weeks earlier but at just what date we have, as yet, no records, but it is evident that at least five months are spent in the region of the breeding grounds. On Natividad, as at Guadalupe and the San Benitos where this species nests to some extent, the introduced cats have killed many adult birds. As cats have been recorded on all of the known nesting islands of the s[>ecies, it would seem Vol. XIVJ ANTHOSV—rHE BIRDS AND MAMMALS 285 to be only a matter of time until the shearwater will be extinct. On two or three occasions shearwaters, the size of opistho- melas, were seen that were ashy gray above and below but otherwise similar to that species. No specimens having been secured it is not safe to venture at identification. 16. Puffinus griseus. Sooty Shearwater The notes on P. crcatopMs will apply to this species as well. They were quite common wherever large flocks of shearwaters were met with, which was whenever we encountered schools of small fish. 17. Puffinus bulleri. New Zealand Shearwater The positive identification of a shearwater at gunshot range is somewhat of a venture and as no specimens of this species were obtained it might seem dangerous to include the species among those noted. However, a large Puffinus with pure white underparts and other characters assigned to bulleri was fre- quently seen between Ensenada and Magdalena Bay, and I have little doubt as to its being this species. In April, 1897, I met with similar birds as far south as Cape St. Lucas. At that time they all seemed to be flying north in either quite small, scattered flocks or singly. None was taken, but I then, as now, would unhesitatingly pronounce them bulleri. If it is not this species it is probably P. chlororliynchus. 18. Halocyptena microsoma. Least Petrel This diminutive petrel was not noted until we were nearly at Magdalena Bay, when a few were seen at sea (July 24). They were inconspicuous at all times, owing, perhaps, to the fact that it was their nesting season and only the non-breeders might be expected at any distance from the San Benito Islands, which is their only breeding ground so far recorded. On these islands we found them abundant, August 12, at which date we took fresh eggs and downy young, the last a ball of down, smoky black in color. So far as my experience goes, 7g5 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. the least petrel does not nest in a burrow in the ground as do the different species of Oceanodroma with which I am famihar. Of the many nests I have seen, all were in bare rocky slides, or similar localities in the rocks, where subdued light might reach the bird. 19. Oceanodroma leucorhoa kaedingi. Kaeding's Petrel While the Tecate lay at anchor at the north anchorage at Guadalupe, July 11-16, this species was quite in evidence, evi- dently nesting in the high lava cliffs that almost overhung the beach. Soon after nightfall their calls might be heard, as those birds that had spent the day at sea came in to land. After lip. m. there was comparative quiet until just liefore daybreak, when for a short time the calling began once more, to cease entirely at dawn. The lights of the vessel attracted a number of birds aboard and these constitute the only speci- mens taken, except a juvenile about a week old that was taken from a crevice in the lava. This specimen, No. 25561, Cali- fornia Academy of Sciences, is nearly uniform sooty gray, slightly lighter below. A few petrels that were considered kaedingi were seen at sea as far south as Ballenas Bay, but they were by no means common even in the region of their nesting grounds on Guadalupe. Dead bodies of this species were found impaled on the needle-like spines of the "cholla" cactus which is quite common on many parts of Guadalupe, the bird evidently having flown into the death trap in the dark. Cats also have taken a large toll, as is attested by the many half-eaten bodies in many parts of the island. 20. Oceanodroma macrodactyla. Guadalupe Petrel Guadalupe Island is, so far. the only recorded habitat of this species. In my several visits to this island I have never seen the bird except as I took them from the nesting burrows. They nest far earlier than the other species of the genus, half-grown young being found as early as May 25, while August would produce young of O. melania of similar size. It is, of course, highly probable that the species leaves the island at the end of Vol. XIV] ANTHOXY—THE BIRDS AND MAMMALS 287 the nesting season, but its whereabouts during that part of the year when it is not at home at Guadalupe still remains a mys- tery. In former years there was a considerable colony along the ridge in the pine growth at the north end of the island. The present writer visited this spot May 26, 1892, and found the birds abundant. In July of the current year the same ridge was explored and but little was seen to indicate a recent occu- pation of the nesting- ground. A few burrows were seen, but they seemed to be very old. In 1892 dozens of dead birds were seen, where cats had torn away the breast, leaving wings and tail, enough to identify the species. Half a dozen similar dried bodies were seen last July, but so few that we were of the opinion the colony was about finished. 21. Oceanodroma melania. Black Petrel This species was seen more or less commonly from the time we left San Diego until we returned, but was rare ; nor was it seen at all far from shore. Nests are not uncommon on the Coronado Islands, but on the San Benito Islands are perhaps the largest breeding grounds of the species so far discovered. August 12, we found many nesting birds with eggs fresh to hatching as well as half -grown young. The nests were usually at the end of a crooked burrow, some two and one-half feet to four feet from the entrance, though a few were found in loose, shelly rock slides. This and the other species of the genus found on the coast might select a similar location and often do, but this is more often in stygian darkness at the end of a three- foot burrow. This species, in common with the other smaller birds of the Benitos, has suffered heavily from the introduced cats. 22. Oceanodroma monorhis. Swinhoe's Fork-tailed Petrel It is with considerable hesitation that I attempt a classifica- tion of this group. O. ''socorroensis" has in the past been the accepted species, being more or less common from the Coro- nado Islands to the San Benitos during the nesting season. I cannot say at this writing just how many times in the past I 2gg CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. have taken from the same nesting burrow white-rumped "so- corroensis" and equally typical "monorhis" with no white at all, but if I were to trust to memory, I would say that that was as often the case as otherwise. I have before me birds from the Coronado Islands as well as from the Benitos that agree exactly with the descriptions and measurements of monorhis, and that were from the same colonies as white- rumped birds or those with white flanks. Unfortunately the collectors neglected to so mark the specimens as to enable one to separate the "pairs" where two birds were found in the same burrow. A large series of petrels, from either of the above localities, shows that one might by selection separate several species or races were it not for the troublesome inter- grades. Birds with pure white rumps, those with white flanks and every form of gradation to sooty-black and typical monorhis can be selected. At this writing, and in the light of the material before me, it might seem the safer course to side- step the issue and leave the decision to further developmnts. Letters, however, from W. E. Clyde Todd, of the Carnegie Museum at Pittsburgh, and Mr. A. J. Van Rossem, of Pasa- dena, California, both of whom have access to large series of the "socorroensis — monorhis" group would indicate that there was but a single species represented with a wide variation in the plumage of the rump. At San Benito Island we found the birds nesting August 12, and secured fresh eggs as well as young a week or more from the ^gg. We saw the species at sea as far south as Magdalena Bay, where, on July 27, a few were seen inside the entrance of the bay in company with O. melania. 23. Phalacrocorax auritus albociliatus. Farallon Cormorant Seen more or less commonly as far as Magdalena Bay. but very largely replaced by the following species south of Abre- ojos Point. During the first half of August this species, in common with the Brandt's, was found nesting on all of the islands north of 27°. Fresh eggs, those far advanced in in- cubation, and from that to young on the wing, was the status of all the rookeries visited as late as August 13. I think the lack of uniformity may be accounted for by the destruction of Vol. XIV] ANTHOSY—THE BIRDS AND MAMMALS 289 the eggs by western gulls. The two species of cormorants breeding along this coast are more extensively preyed u^x^n by the gulls than any other species and should the cormorants be driven from the nests, eggs and young by the hundreds are immediately destroyed. As has been noted earlier in this paper, all of the islands are used, during a great part of the year, by fishermen, who undoubtedly cause a very disturbed condition, innocently or otherwise. They are the indirect cause of the destruction of many thousands of cormorants as well as other sea birds. The Farallon cormorants were always found occupying the higher and more precipitous parts of the islands, leaving to the following species the gentle slopes and level land. 24. Phalacrocorax penicillatus. Brandt's Cormorant Much more abundant than the preceding species. Despite the disturbed condition of the nesting grounds, there were large rookeries on most of the islands visited. On the more level parts of San Roque and Asuncion were several large rookeries that at the time of our visit were occupied by hun- dreds of young, ranging from those able to fly to squabs but just hatched. As one approached the nesting grounds, the young crowded toward the side farthest removed from the in- truder, until it seemed as if it would be impossible to introduce another bird into the interior without the aid of a w^edge, so tightly were they massed. As the danger became more evident, the compact raft moved faster, the older birds in the lead pro- gressing by a series of awkward hops which soon left the younger members behind. As more speed seemed desirable the wings were called upon, waved about like flails, and so upset the balance that immediately the youngster that was merely in a slow hurry at best was thrown forward on his face and quite as often as otherwise stepped on his own neck and was unable to get up. If crowded, the half-grown young will take to the water and escape by swimming, though many times such birds are unable to regain the nesting ground owing to the low cliffs bordering the sea below the rookeries. The fate of such birds is somew^hat doubtful, as they are as yet unable to secure their own food. September 5. 192.5 290 CALIFORNIA ACADEMY Of SCIENCES [Proc. 4th Sf.r. 25. Pelecanus californicus. California Brown Pelican An abundant species along shore throughout the trip, but rare in deeper waters. A single immature bird seen at Guada- lupe is my only off-shore record. At Magdalena Bay they were noticeably more abundant than at any point north. At many of the islands, notably San Roque and Asuncion, we found fresh eggs and newly hatched young, as well as birds on the wing. As only a single brood is raised and young are to be found in late February or early March, the late nesting can only be explained on the ground of reported disturbances, as noted under s^^ecies above mentioned. 26. Fregata aquila. Man-o'-war-bird Very abundant south of 26°. This species formerly nested extensively in the mangrove swamps about Magdalena Bay, but repeated raids on the part of the natives who use the eggs for food have reduced their numbers. Owing to the nature of the mangrove growth, it is quite difficult to reach the nests, which fact has been the only restraining influence in preserving the nesting grounds in this region. 27. Oidemia perspicillata. Surf Scoter A few only seen in San Quintin Bay — non-breeding birds, no doubt, that did not migrate. Such cases are common. During the winter the species is very abundant ail along the coast. 28. Erismatura jamaicensis. Ruddy Duck A single bird in San Quintin Bay is the only record for the voyage. 29. Guara alba. White Ibis Seen only in the mangroves at Magdalena Bay, where it was not very abundant. As the more remote parts of the jungle north of the settlement were not visited, it may be that the species was less rare than our observations would indicate. Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 291 30. Ardea herodias sanctilucae. Espiritu Santo Heron Not uncommon on the islands near shore and at most, if not all, of the mainland stations. Two or three were seen at Guadalupe Island. 31. Hydranassa tricolor ruficoUis. Louisiana Heron Seen only in the mangroves about Magdalena Bay, where it was common. Formerly I have taken specimens as far north as San Quintin, but I think it was never abundant there. 32. Butorides virescens frazari. Frazar's Green Heron Found not uncommonly at Magdalena Bay, where they shared the mangrove thickets with the above species. 33. Nyctanassa violacea. Yellow-crowned Night Heron A single specimen shot on a reef at San Benito Islands is the only record. 34. Rallus beldingi. Belding's Rail None seen, but the frequent notes of Rallus heard in the mangroves at Magdalena Bay leave little doubt as to the species and its abundance. 35. Phalaropus fulicarius. Red Phalarope The first of the migrating phalaropes were noted July 11. when two were seen between Ensenada and Guadalupe Island. After that date they rapidly increased in abundance until the 18th, when they seemed to be in full force. They were not seen over 50 miles off shore. 36. Lobipes lobatus. Northern Phalarope Seen but once, August 2, off San Roque Island. 292 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. 37. Pisobia minutilla. Least Sandpiper 38. Ereunetes mauri. Western Sandpiper On July 26, a small flock of "sand peeps" was seen on a mudbar in the mangroves of Magdalena Bay. None was shot and positive identification was difficult. The two species usually migrate in company and it is quite probable that the flock was composed of both species. A week later we met with them migrating and in early August they were seen at all of our anchorages north of Magdalena. 39. Limosa fedoa. Marbled Godwit A few were seen at San Quintin on July 21. They occur sparingly all summer in all of the suitable localities from Mag- dalena Bay north, the summer residents being non-breeding birds that have failed for some reason to follow the migration north. 40. Totanus melanoleucus. Greater Yellow-legs Two were seen on a mudbar in the mangroves at Magda- lena Bay, July 26. The one secured was in fair summer plumage. 41. Catoptrophorus semipalmatus inornatus. Western Willet First seen at Abreojos Point, July 31, in a company of mixed shore-birds, evidently the first of the migrants. Quite common at San Quintin, August 14. 42. Heteroscelus incanus. Wandering Tattler First seen at Guadalupe Island, July 11. While not common at this island, they were frequently seen along its rocky shores. The same may also be said of all the islands visited. Although found at all seasons of the year, those that linger through the summer are probably not nesting birds. I have found downy young seeking cover under the overhanging edges of glaciers Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 293 of the Seward Peninsula in Alaska, conditions hardly in keep- ing with those of the sun-scorched shores of the Lower Cali- fornia islands. 43. Actitis macularia. Spotted Sandpiper First seen at Magdalena Bay in company with greater yel- low-legs, July 26, after which they were seen at any suitable location north to San Martin Island. This species is rather common along the islands and coast of Lower California dur- ing the winter months, inhabiting rocky broken beaches in company with its larger relative, the wandering tattler. They, like the last, are seldom seen in companies of more than three or four, more often singly or in pairs. 44. Numenius americanus. Long-billed Curlew Seen at San Ouintin, July 18. Not uncommon at that point where, like the marbled godwit, it is a left-over from the spring migration. 45. Numenius hudsonicus. Hudsonian Curlew A few found along the ocean beaches all summer, being like the above, non-breeders. This species seems to prefer the clean sands of the open beach and is not often seen on the mud-flats of the bays, where the long-bills thrive. A small flock of hudsonicus was seen at the entrance of San Quintin Bay, July 14. 46. Squatarola squatarola cynosurae. Black-bellied Plover A few seen among the migrating shore-birds at Abreojos Point, July 31, the first to arrive from their summer home. 47. Oxyechus vociferus. Killdeer One or two noted near the settlement at the mouth of Santo Domingo Caiion, fifteen miles north of San Quintin. The species is resident in such localities, where freshwater furnishes congenial surroundings. 294 CALIFORNIA ACADEMY OF SCIENCE^ [Proc. 4th Ser. 48. Charadrius semipalmatus. Semipalmated Plover A small flock seen at Magdalena Bay, July 27. 49. Charadrius nivosus. Snowy Plover A small flock seen on the beach at Abreojos Point. 50. Arenaria interpres morinella. Ruddy Turnstone A flock seen at Abreojos Point. The single bird that was secured was in almost full nesting plumage. 51. Arenaria melanocephala. Black Turnstone Rather common at Abreojos Point, July 31, after which it was seen on all the rocky beaches north to San Martin Island. Two were seen at Guadalupe, July 16. 52. Haematopus frazari. Frazar's Oystercatcher Seen on all the rocky shores from the south end of Mag- dalena Bay north. Often seen in company with bachinaiii to which it ofifers a striking contrast. 53. Haematopus bachmani. Black Oystercatcher Not seen south of Asuncion Island, where it was common. From that point north it was common on all suitable beaches. 54. Lophortyx californica vallicola. Valley Quail Common in the section east of San Quintin which is the only spot visited that was suited to its requirements. 55. Zenaidura macroura marginella. Western Mourning Dove Found breeding on Cedros Island, July 22, when young just from the nest were seen. Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 295 56. Cathartes aura septentrionalis. Turkey Vulture Quite common at any of the larger islands except Guadalupe and as far as Margarita Island at the southern end of Mag- dalena Bay, 57. Parabuteo unicinctus harrisi. Harris's Hawk Seen but once, near San Quintin, where the species is not uncommon along the timbered cafions east of that point. 58. Buteo borealis calurus. Western Red-tail Several were seen on Guadalupe Island and one specimen taken. 59. Falco peregrinus anatum. Duck Hawk Formerly quite common, nesting on all of the islands north of Magdalena. Few were seen, however, on the voyage of the Tecate, due, perhaps, to the season being that when the birds might be expected to be scattered far from their nesting haunts. A line specimen was taken on San Benito, August 13. 60. Polyborus cheriway. Audubon's Caracara Seen only at Margarita Island, where it was seemingly rare. There is little doubt but the Guadalupe Caracara is extinct ; no signs of it could be found by members of our party, nor have any who have visited the island during the past 20 years re- ported living birds. 61. Pandion haliaetus carolinensis. Osprey First seen at Guadalupe Island, where a specimen was secured. Quite common at Cedros Island and most of the stations visited. On Margarita Island there are dozens of nests built on tops, or on projecting limbs, of the giant cactus. 296 CALIFORNIA ACADEMY OF SCIENCES [PRoc 4th Ser. 62. Speotyto cunicularia hypogaea. Burrowing Owl Seen only at San Quintin. The burrowing owl was form- erly found on the San Benitos, Natividad and other islands of the coast, where it was resident. It is possible that it has been exterminated by the cats. 63. Geococcyx califomianus. Roadrunner Seen only at San Quintin. 64. Dryobates scalaris lucasanus. San Lucas Woodpecker This species was common, feeding on the ripe fruit of the giant cactus, on Margarita Island. Not met with elsewhere. 65. Centurus uropygialis brewsteri. Brewster's Woodpecker A rather abundant species in the giant cactus growth on the west side of Margarita Island, where it was feeding on the ripe fruit of the cactus. All the specimens taken were in badly worn plumage, but indicate a strongly marked race. 66. Chordeiles acutipennis inferior. Texas Nighthawk A few seen at Magdalena Bay and on Margarita Island. The single specimen taken (No. 25530 C.A.C. ) agrees fairly well with skins before me, from southern California, except that it is slightly smaller. 67. Aeronautes melanoleucus. White-throated Swift On the southeast side of Guadalupe Island we saw a number of these swifts cruising about the cliffs overhanging the sea. It was near this same spot that I found, in May, 1892, a nest but so far back in a crevice in the lava that without tools to enlarge the opening it could not be reached, though the sticks composing the structure could be plainly seen. On July 19 I saw several swifts in company with cliff swallows flying about a cliff at the mouth of the Santo Domingo Canon, 15 miles Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 297 north of San Quintin. Several years ago I saw this species entering- abandoned woodpecker holes in the giant cactus near San Fernando, about 75 miles south of San Quintin. 68. Calypte anna. Anna's Hummingbird At the north landing on Guadalupe Island we saw a hum- mer in female plumage that seemed to be this species. It es- caped, however, leaving its identity in doubt. W. E. Bryant recorded the species from the island many years ago. 69. Calypte costae. Costa's Hummingbird This species seemed to be the only one we met with at Mag- dalena Bay and Margarita Island, where several were taken in late July. Specimens were secured also at Cedros Island. 70. Myiarchus cinerascens pertinax. Lower California Flycatcher Flycatchers of the ash-throated group were seen several times on Margarita Island, but no specimens taken. I sup- posed them to belong to this subspecies. 71. Sayornis sayus. Say's Flycatcher Common about San Quintin. On Cedros Island it was seen several times. A young male (No. 25531, C.A.S., August 8, south end Cedros Island) is somewhat darker above than specimens of similar age from southern California, with slight- ly narrower bill. The difference may be individual, however. 72. Sayornis nigricans. Black Phoebe Seen only in the Santo Domingo Canon near San Quintin. 73. Otocoris alpestris actia. California Horned Lark The Otocoris of San Quintin. I refer to this form with some hesitation, as no additional specimens are at hand, a sin- gle juvenile in the collection of the Academy being the only 298 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. bird taken. At Abreojos Point a small flock of horned larks was seen and three badly worn and juvenile specimens secured. They seem very small and can hardly be reconciled to any of the recognized races, they being, I suppose, enertera Oberholser. 74. Aphelocoma californica hypoleuca. Xantus's Jay A rather common inhabitant of the mangrove swamps north of the anchorage at Magdalena Bay. Not seen elsewhere. 75. Corvus covax sinuatus. Raven A common species throughout the trip. Seen at every sta- tion except at Guadalupe. 76. Carpodacus mexicanus frontalis. House Finch Common at San Ouintin and at the nearby mission of Santo DominsfO. ';=>" 77. Carpodacus amplus. Guadalupe House Finch Formerly one of the most abundant land birds on the island but now reduced to about 10% of its abundance 25 years ago, the destruction being due to the thousands of cats that infest all parts of the island. The species nests largely in the cactus found over most parts of the island, which fact saves the nest- lings until able to flutter to the ground, where they fall nn easy prey. 78. Carpodacus mexicanus dementis, San Clemente House Finch Common on Cedros Island. Five specimens were obtained. 79. Carpodacus mcgregori. McGregor's House Finch A quarter of a century ago this was one of the few land species that was common on the San Benito Islands. Today they are so nearly extinct that I doubt another specimen being Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 299 taken for science. Like the last mentioned species, they have fallen victims to the cats. A single specimen was all we had to show for four guns in two days. A second specimen was reported as seen. 80. Astragalinus praltria hesperophilus. Green-backed Goldfinch Two females taken at the south end of Cedros Island. They seemed to be nesting in small numbers on this part of the island. Those taken are somewhat smaller than typical speci- mens from southern California, but whether the difference is constant will remain for further specimens to determine. 81. Passerculus beldirigi. B elding Sparrow Seen only at San Quintin, where it is common in the salt marsh. 82. Passerculus rostratus rostratus. Large-billed Sparrow This species winters on all of the islands, I think, except Guadalupe, and had just begun to make its appearance when we noted a few along the beaches at the north end of Cedros, August 9. A single specimen was taken on San Martin Island, August 14. 83. Passerculus rostratus guttatus. San Lucas Sparrow A few noted in the mangrove swamps of Magdalena Bay, and a single specimen taken July 26. 84. Passerculus rostratus sanctorum. San Benito Sparrow Found only on the three islands of the San Benito group, where they are still common but greatly reduced from their former abundance. The cats are again to be given the credit. 300 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. 85. Junco insularis.

Cliff Swallow Common and nesting under the eaves of the houses at San Quintin, where nestlings were seen, July 20. On the same date a large flock was seen circulating about the face of a cliff at the mouth of the Santo Domingo Canon. A small flock, doubtless migrating, was noted flying over the mangroves at Magdalena Bay, July 26. Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 301 List of Species of Mammals In the following list of mammals the nomenclature of Miller's "List of North American Land Mammals in the United States National Museum" has been followed. As the series of Lower California mammals in the collections of the San Diego Museum of Natural History and the Cali- fornia Academy of Sciences are very incomplete, I have been obliged to depend in many instances on the collections in the U. S. Bureau of Biological Survey and the American Museum of Natural History, New York. My thanks are due Dr. E. W. Nelson and H. E. Anthony for comparison of several species with the types. 1. Balaenoptera physalus. Pacific Finback Whale Whales were often seen along the coast and about all of the islands with the exception of Guadalupe. They were nowhere common, and all that were identified with reasonable certainty were of this species. It is quite probable, however, that some seen were humpbacks. The larger cetaceans are more abundant during the winter months in the region covered by this paper, but they were formerly far more abundant than today. In the past, when the fall migration was at its best (November) I have seen more whales in one school than were seen during the entire southern voyage. At the time mentioned, 25 years ago, the California Gray (Rhachianectes glaucus) was the most common species and was daily seen along shore, often inside the kelp beds, within half a mile of the beach. During the past two years I have seen just two of this species and had reports of two more, while the Sulphur Bottom (Sibbaldiiis sulfiireus), form- erly quite common, has not been seen at all. The modern method of whaling has sounded the death knell. Commercial whaling is about a thing of the past and, unless something is done soon toward protecting them, several species will soon become commercially, if not actually, extinct on this coast. Nearly all of the whales seen during the voyage of the Tecate were close in-shore, frequently at the edge of extensive kelp beds and, as they were usually seen in pairs, it is not un- 302 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. likely that they were mating. In late July and early August, there was a very extensive run of sardines along the entire coast and, as these small fishes furnish many of our BalccnidcB with a large part of their feed, that may account for the entire absence of whales in deep water and their presence along the shores where the sardines abounded. During the winter of 1920-21, a steam whaler established a station in Magdalena Bay and spent several months at that point. From the bones still to be seen on the beach, they must have killed several whales but, as they never repeated the venture, it is quite probable it was not a commercial success. 2. Orcinus ater. Black Killer Killers were formerly much more common on the Lower California coast than the results of our late voyage would in- dicate. But one small school of s^'ven or eight was seen several miles off San Quintin, July 18. There is no question but the killers are a bitter enemy of the entire BalcEuidcu. While I have never myself seen the species attack a whale, I have often been told by reliable authority of combats that resulted in the death of the larger "fish." It may be that the present rarity of Orcinus is directly due to the scarcity of whales. The Orca often reaches a size (twenty feet or more) equal to that of a small whale, but whalers never attempt its capture, as it is of little or no value. 3. Grampus griseus. Grampus A single specimen, identified as this species, was seen off San Quintin, July 18. South of Cedros Island there were several times when large porpoises were seen, but under con- ditions rendering identification impossible. Tiiey may have been this species. 4. Delphinus delphis. Common Dolphin On the southwest side of Cedros Island we found a well preserved skull of this species. Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 303 5. Notiosorex crawfordi crawfordi. Gray Shrew A specimen taken in the edge of a salt marsh on the west side of San Quintin Bay is not separable from skins from the region of San Diego in the collection of the San Diego Society of Natural History, 6. Pipistrellus hesperus hesperus. Western Bat At the anchorage at Margarita Island we met with a flight of bats at daybreak, July 28. They were seeking shelter in the ledges along the shores. Two were secured and are not to be distinguished from specimens taken at San Diego and the Colorado Desert. 7. Canis peninsulae. Peninsula Coyote Not uncommon at San Quintin, where one or two were seen. Skulls were secured at Magdalena Bay. 8. Enhydra lutris nereis. Southern Sea Otter Formerly very abundant on the coast of Lower California, as far south at least as Natividad Island. The early records abound in stories of the numbers of sea otter found along this coast where, alas, they were soon exterminated, or at least so reduced that they became almost a myth. In 1807 the ship Dromio from Boston is recorded as trading for 1700 otter skins at Ensenada, then inhabited by a few Indians who must have taken the animals along the kelp beds adjacent to that bay. Capt. Benjamin Morrel in 1825-31 made four voyages to this coast from the Atlantic and men- tions "immense numbers of whales, seals, and otters at San Quintin and Cenizas (San Martin) Island." In 1887 when I first became acquainted with the region of Todos Santos Bay and the former haunts of the sea otter, they were generally considered as extinct. There were, however, a few of the old-time hunters that assured me that in the region of certain kelp beds south of Ensenada there were a few to be found. This, I learned, was true, and a small colony was 3Q4- CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. established that by now might have been of large commercial importance had it been protected. Unfortunately, it was discovered by certain "beach combers" in 1897, and to the best of my information some 50 were killed. There is a report of 28 being killed eight or nine years later at the same point, but I am unable to authenticate it. That a few still exist, as far south as Cedros, there can be little doubt, as one was killed by a fisherman in 1919, at San Benito Island 15 miles west of Cedros. They were formerly abundant along the kelp beds found along the weather side of Cedros and the Benitos, and in time may be re-established there, if unmolested. 9. Zalophus californianus. California Sea Lion An abundant species on most of the islands visited except Guadalupe, where one rookery of a dozen was found and a few scattered individuals along the shores that might have made the Guadalupe count as much as 50 animals. They were about abandoning the breeding rookeries in August so that a census of the various colonies was out of the question, but from what we found I would place the present count of sea lions, of the coast of Lower California, at fully 150% above what might have been found in 1900. At the last date the species was being persecuted for hides, the rookeries being raided constantly during the season of reproduction. Fre- quently hundreds of young were left to starve beside the bodies of the slain mothers. At Asuncion Island in 1898, I found a rookery of not over 50. The count at this island in August, 1922, was over 5,000. As San Roque Island, only six miles north of Asuncion, was almost deserted by Zalophus, it is quite probable that Asuncion was being used as a hauling ground for sea lions from both islands. At Cedros Island there were several large rookeries, but at the time of our visit the animals had begun to scatter and it was not possible to secure a census. I had confidently expected to find at the north end of this island the star sea lion rookery of the coast, as that was its condition in 1898 when it was populated by some 2,000 breeding animals. At the time of our visit, August 9, there were 1.500 Zalophus hauled on the sand Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 305 beach at the north bay and some 700 on a beach about two miles south. On the east side of the island two detached rocks formed ideal resorts for sea lions, but we found only 300 at this point. San Benito Islands, where Townsend, in his report of the Albatross Expedition in 1911, mentions finding 1,700 Zalophus, gave us not over 400. We frequently met with sea lions many miles from the known hauling grounds and far from land, indicating a scat- tered condition quite different from what would be found in April when a large percentage w^ould be collected on the breed- ing rookeries. On the Lower California islands the pups are born about June 10, and are about six weeks or two months old before they go into the water, though a young sea lion a week old can and will swim if forced to do so. A baby sea lion spends a large part of its early life in sleep, which is sur- prisingly difficult to disturb. The present writer has, on several occasions, visited a rookery where the beach w^as strewn with sleeping pups, seated himself among them and gathered one or two into his lap, and played with them for several min- utes before they were sufficiently aroused to realize the true situation. Their surprise was always laughable, as they voiced a horrified baby imitation of daddy's roar and perhaps made a bluff at amputating a human hand or tw^o. A newly-born sea lion is possessed of a full set of needle-like teeth and ample strength to make them serviceable, but, of the many that have by their actions promised to seriously mutilate me, none has yet drawn blood, and such fierce savage beasts have, after a ten- minutes' fondling, refused to be left alone and frequently follow^ed, bawling, along the sand, as if they were losing their best friend. In this connection might be mentioned an incident in which a sea lion figured, which illustrates the confiding nature of the animal when it is not persecuted. In April, 1922, a seaplane from the North Island Aviation Field made a landing at sea about 30 miles from the Coronado Islands and about the same distance from the mainland. Shortly after the plane came to rest, the pilot heard a scratching on the side of the machine and looking over saw a yearling sea lion investigating the strange craft. The door to the cockpit was held open and the invita- tion promptly accepted, the seal returning to San Diego by air- September 5, 1923 306 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. plane. I visited the station a few days later and found the visitor to be a yearling female and as eager to be noticed as any pet kitten. Though given the freedom of the bay, it always returned to its new home on being called and never at any time showed any disposition to return to the company of its fellow lions. 10. Arctocephalus townsendi. Guadalupe Fur Seal That fur seals of some species were at one time abundant on most, if not all, of the islands of the peninsula, as well as those of Californ'^, cannot be disputed. There are undoubted records of many thousands of skins being taken from the Farallons and the islands south to Cape St. Lucas. At this time it is largely a matter of conjecture as to even the genus. During the fur seal controversy between England and the United States in 1892, Dr. Charles H. Townsend and the present writer visited Guadalupe Island in the hope of securing specimens of the fur seal said to have once existed there. The net result of our trip was four more or less broken skulls upon which was based a genus and species new to North America, Arctocephalus townsendi. In Dr. Townsend's report he men- tions several living specimens as being seen but not taken. In the light of recent events, I have some doubts as to the animals seen were really fur seals ; they may have been young California sea lions. The yearling Zalophus is quite easily mistaken under conditions such as we encountered, and though we may have seen Arctocephalus it is by no means certain. However, in 1893. there were said to have been 35 fur seals killed on Guadalupe and 15 the year following, the last being the final record, so far as I know, although I am of the opinion that a few were taken from year to year for some time. One of the chief ob- jects of the voyage of the Tecate in 1922 was to secure all evidence possible as to the fur seal in the past and to ascertain if living animals were to be found. On July 16 we examined the old rookery at Jacks Bay on the weather (west) side of the island, where the skulls of Arcto- cephalus were found in 1892. At this point we found a re- markably well defined rookery, marked by well polished rocks, Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 307 that at one time accommodated fully 30,000 adult seals. As is well known to those familiar with the habits of fur seals, they restrict themselves to certain limits, preferably a boulder- strewn beach, where in time — hundreds of generations perhaps — the rocks become polished and the rookery limits defined as sharply as if painted. A short distance inland from the rookery are eight stone huts, four of which were seemingly for store- houses and four for living quarters. The walls only are left, and it is evident that the roofs were of canvas or hides. Still further inland is an extensive area of land cleared of stones and, leading to it from the rookery, a walled driveway, the walls being of stones and palm logs — the cleared space being the killing and skinning grounds. From the evidence obtainable, this was the work of Russians, who came from the north with Aleuts not less than 125 years ago. Not a bone or fragment is left of the many thousands of fur seals killed there in the past. At the south end of Guada- lupe is a still larger rookery, estimated to have been populated by 30,000 or more. Here, as at Jacks Bay, are a number of stone walls marking the sites of storehouses and living quar- ters. On the beach above the rookery, the cleared area is marked by thousands of wooden pegs once in use to hold the skin stretched until dry enough to store for shipment. Many of the pegs today mark the outlines of what was a seal skin over 100 years ago, and so kindly have the elements treated the wood that there is scarcely any decay, but here, as at the northern rookery, no bones of Arctocephalus were found. A somewhat smaller fur seal rookery was found on the east side of the island, and it was estimated that at one time Guadalupe was populated by at least 100,000 fur seals, old and young. I have knowledge of two fur seals being shot on the west San Benito in about the year 1890. While the Guadalupe Fur Seal was resident to a far greater degree than its northern relative, there were periods each year for some two or three months when it left the islands and dis- appeared. Where it went the hunters were unable to tell me, nor can I even say at what time of the year it migrated. During a large part of the time it was found about the island. It in- habited the many caves found here, and there is a chance that 308 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. some such cave dwellers may have been overlooked at the time we were exploring the islands. I find among the early records of the islands some very inter- esting notes on the fur seal, as the log of the Port au Prince, a whaler that sailed from England, February 12, 1805, and toucned at Cedros for a cargo of elephant seal oil. Leaving Cedros on August 23, she proceeded to the Benitos 15 miles west, where in 19 days, 8,338 fur seals were killed. The ship Dromio, out of Boston, arrived at "Shelvrocks Island" (Socorro) in November, 1808, and in two weeks killed 3,000 fur seals. Another early navigator states that as he found the northern islands — Santa Barbara Islands and those of Lower California — being sealed by the Russians, he proceeded to Socorro where, in a day's search he saw some 20 fur seals and 1,500 sea lions. The fur seal outlook not being inviting. the ship did not engage in that trade. The fur seals of Guadalupe must have been commercially ex- terminated by the Russians early in the last century, for noth- ing seemed to have been known of them during the American occupation of California until about 1876, when they were acci- dentally discovered by a schooner from San Diego, and for a short time a profitable trade was enjoyed by a number of small craft. The curtain was rung down on the last act in 1894, when 15 were said to be the season's catch. We have authentic records of 5,575 being killed at Guadalupe and San Benito between 1876 and 1894. Whether there will be others in the years to come remains to be seen. 11. Phoca richardii geronimensis. San Geronimo Harbor Seal This species never was very abundant on the coast of Lower California, but a few were seen on the sand bars in San Ouintin Bay. On San Roque Island, August 2. there were a dozen or more on the rocks. They seem to avoid the company of other species, and are more at home on the sand bars and mud flats of enclosed waters than the rocky shores and surf that seem to suit the requirements of Zalophus. Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 309 12. Macrorhinus angustirostris. Elephant Seal The history of this most interesting- species is filled with tragedy. Once it was abundant from the region of Santa Bar- bara to Magdalena Bay, some 800 miles of coast line. It became so reduced in numbers, due to extensive slaughter on the part of the early whalers who killed the animal for the oil, that as long ago as 1869, Scammon regarded it as "nearly, if not quite, ex- tinct." Since that day naturalists have several times unexpect- edly encountered a small family and, in killing them, have secured for science what they honestly looked upon as the last of the species. Although the taking of these last survivors was regarded as regrettable in the extreme, it was considered justi- fied, on the grounds that the species was doomed to die at the hands of whalers or sealers, and museums were in need of the specimens. The present condition of the remnant of the once abundant species speaks volumes for its ability to rebuild, if given oppor- tunity. In 1911, Charles H. Townsend found 150 on the west side of Guadalupe, at the same hauling grounds where he and the present writer found nine in 1892, — of which seven were killed for the National Museum at Washington. On the return of Dr. Townsend's expedition, the newspa|)ers of the coast featured the rediscovery of this strange creature in such man- ner that the public was led to think that the capture of one meant an independent fortune for the captor, and as a result to be expected the fishermen of southern California flocked to the spot to reap the harvest. It would be impossible to state how many were killed, but they were numerous and, needless to state, the specimens thus killed were of no value to museums. The Mexican Government, at this stage of the game, placed an embargo on the killing of elephant seals, and, for a time at least, the few living were given a respite. In the winter of 1920-21, an enterprising whaler, hearing of the occurrence of the species on the coast of Lower Cali- fornia, outfitted for a cruise that was intended to bring their history to an end. Fortunately, however, it was supposed that the elephant seals were in the Gulf of California. Guadalupe 3IQ CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Island was not visited, and the voyage, from a commercial point, was a failure. About the time plans were being made for the total extermi- nation of this species by way of the whaler's try-pot, a com- pany operating a fertilizer plant in California applied to Dr. Hanna, of the California Academy of Sciences, tor information as to the whereabouts of the sea elephants, stating they wanted to use what were left for a few days' run of their plant. Need- less to state, the information was not given, and while some cabbage field may have lost a temporary stimulant, the ele- phants were given another reprieve. In July, when the Guada- lupe elephant bjach was visited by our expedition, we found 264 animals hauled on the sand, 14 of which seemed to be young of the year and presumably there was an equal number of mothers. While the adult animals are quite fearless, even almost impossible to disturb to the extent of causing them to leave the beach, the pups were rather timid and before the dis- parity of sexes was noticed all the pups had gone to sea, and with them the females, leaving only the bulls to interview the intruding naturalists. At this date (July 12) the younger ani- mals had seemingly finished the moult and were in a dark gray or blackish coat, — ^black when first emerging from the water. Most of the larger bulls were in a tattered, ragged condition, indicating the extreme moult, the neck and anterior parts of the body being hung with streamers of cuticle and hair, oftentimes several inches in length, hanging from pink or flesh-colored undersurface, suggesting a bad case of sunburn. In moulting, not only is the hair renewed but the entire cuticle seems to be shed, the beach being strewn with patches of the old coat oftentimes as large as a man's hand. On ex- amination of these detached patches of cuticle and pelage, it is difficult to tell at a glance which was the inner side, the hair extending 3 mm. beyond the cuticle on its inner surface and 10 mm. for the exterior measurement. The color is somewhat lighter on the flesh side as well. These animals with the old moulting coats were more or less uniform yellowish-tan, or what is generally recognized in the West as "buckskin" color, contrasting strongly with the darker — almost black — coats of Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 2)\\ the younger males that had completed the mouU. The pups that we assumed to be of the current year were about 175 pounds in weight, dark gray above, with an obscure motthng of the coat in certain hghts, suggestive of the spots in the coloring of Phoca richardii, the upper coloring gradually fad- ing to a very light gray — almost white — below. A yearling size juvenile was estimated to be of about 500 pounds weight and, like the adults, uniform dark gray. In the adult female the coloring is similar, the only difference being in the almost total lack of the nasal development so character- istic of the adult male. In this respect they resemble quite closely the undeveloped males. A male elephant seal was shot for the Mexican collections and, though several shots were re- quired to dispatch the animal, those 10 feet distant paid little or no attention to the disturbance. The stomach contents of this animal was a small amount of the volcanic sand of which the beach is composed. In 1892 I found sand and pebbles the size of hens' eggs in the stomachs of those taken for the National Museum, and in only one was there any indication of the food — a fish, Sebas- todes( ?), of about one and one-half pounds, together with a few fronds of kelp that were doubtless unintentionally taken along with the fish, was taken from the stomach of one young male. Before landing, the animals spend some time along the surf and it is quite possible that digestion is complete before they land. The stones and sand are no doubt taken from time to time in capturing their finny prey, and is not in any manner intentional. Similar matter has been reported as found in the stomachs of sea lions and fur seals, and has been mentioned as "ballast" that is taken by the seal before going into the water, — a story that should be classed with that of the hoop- snake. An alarmed elephant seal will often "back up" at a pace ex- ceeding that usually shown in advancing. This is accomplished by repeated, sudden jerking of the hind flippers and posterior part of the body, and is suggestive of the progress of a freshly 312 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. captured lobster. At times they will back down the beach and into the surf in this manner rather than turn and perhaps lose sight of the object that threatens. Upon coming out of the water, the adults leisurely crawled up to a point well above the tide, frequently pausing to rest, as if the effort were con- siderable. No use is made of the posterior limbs, the body being laboriously dragged along by action of the short but very powerful front flippers and the muscles of the abdomen, somewhat as an "inch worm" progresses. Finding a spot suited to its ideals, the animal usually proceeds to pitch sand over its back, using the front flippers as shovels until the upper parts are well sanded. The same shovels and lava sand also come in play as means of defence, for on several occasions when an animal was disturbed by members of our party a dis- charge of sand, sent with almost the force of bird shot, caused a hasty withdrawal. It was quite evident that the barrage was intended as a defence, for while the sand intended as a cover- ing for the back is always tossed six or eight feet in the air, to land largely on the animal, when intended for the face of a man it was shot backward at a low angle, the seal looking back over the shoulder to note the effect and turning with surpris- ing quickness to keep the intruder in range of its artillery. The adult males are somewhat quarrelsome and, to judge by the battle-scarred necks and shoulders, indulge in some com- bats that are decidedly sanguinary. At the time of our visit, however, an armistice had been declared. Two bulls meeting often snapped at each other, raising the heads to a surprising height — eight feet or more, — mouth open and attitude threatening in the extreme, and such battles resulted in more threats. When challenging, the bulls often curved the flexible proboscis over into the wide open mouth until it must have been nearly at the base of the tongue. At such times they gave voice to the only sound I have heard, a loud gurgling roar, that might be compared to a much magnified snore. I have heard this note when half a mile or more from the ani- mal. At times, also, the trunk is elevated and recurved until it points almost backward. At rest and in its normal position, it is withdrawn until it overhangs the mouth but little and rests Vol. XIV] ANTHONY— THE BIRDS At^D MAMMALS 313 ill two or three grotesque folds, extending back nearly to the eyes. Estimating the number of female and immature elephant seals on the basis of the adult males we found on the beach in July, the entire Guadalupe herd should easily be 1,000 animals. There were over 300 adult males on the main beach on our return, July 16, and at the entrance to a large cave north of the beach we found 36 more, all males. The cave being all but closed by the high tide, we were unable to ascertain what might be inside. The Mexicans, however, on a subsequent visit to the island early in September, found "150 females and an equal number of pups about thirty inches in length inside the cave." If this information regarding the young is correct, those which we saw in July and considered as young of the year were about ten months old — as the pups of the California sea lion, Zalo- phus, are fully 30 inches in length at birth. There would seem to be something further needed in way of data before we defi- nitely state that the animals seen were in fact Macrorhinus. Several years ago there were a number of elephant seals captured at Guadalupe and taken to one of the amusement piers near Los Angeles, where for a time they were on exhibi- tion. A storm destroyed the pier and the seals escaped. On two or three occasions the species has been reported from dif- ferent points along the Santa Barbara Channel, and it is quite probable that it is the escapes that were seen. There may perhaps be a small breeding herd established at some of the outlying islands which, if protected, will in time re-establish the species in its old-time haunts among these islands. For several years past a few elephant seals have been seen about the San Benito Islands, but it is certain that no colony has yet been established there. They have been seen in May and October and in sunicient numbers to indicate that more than a mere few might have wandered from the main herd. They no doubt in due time, if the present protection is en- forced, will regain their lost rookeries on San Benito and Cedros. We found a number of badly weathered skulls on each of the above mentioned islands, where the whalers of 50 years or more ago had killed the animals for their oil. 314 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. The Mexican Government has recently designated both Guadakipe and Cedros islands as animal refuges, with a very heavy penalty for any infraction of the lav^. If the regulations are enforced, there is no doubt but the present species, as well as others, the future of which is in danger, may enjoy many more years of existence. 13. Peromyscus eremicus cedrosensis. Cedros Island White-footed Mouse Specimens are in the collections from each of the five sta- tions made on .Cedros Island. The species seemed to be rare in the interior, out very common along the beaches. 14. Peromyscus eremicus polypolius (?) Margarita White-footed Mouse Several Peromyscus were taken on Margarita Island, but all were so badly mutilated by ants that little could be learned of the external appearance. One specimen was seemingly of an almost uniform ashy or pearl gray, lighter below, — perhaps an albino. 15. Peromyscus maniculatus sonoriensis. Sonoran White-footed Mouse It is with some hesitation that I refer a single Peromyscus from San Quintin to this race. The specimen is immature and agrees in a general way with specimens from southern Cali- fornia of similar age, but the tail is much more sharply bicolor and the lower parts more decidedly white than any in the col- lection of the San Diego Society of Natural History. 16. Peromyscus maniculatus coolidgei. Coolidge White-footed Mouse At San Bartolome Bay two specimens were taken. Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 315 17. Peromyscus maniculatus geronimensis. Ashy-gray White-footed Mouse Very abundant on Natividad Island, the only station in its habitat at which we touched. 18. Peromyscus maniculatus cineritius. San Roque White-footed Mouse Very abundant on Asuncion Island. San Roque Island, the type locality of this subspecies, is but six or seven miles from Asuncion and with exactly similar conditions and environment. No traps were set on San Roque, so I am unable to make a di- rect comparison with specimens from that island. Specimens were sent to the American Museum of Natural History and compared with types by my son, H. E. Anthony, who states : "Very close to cineritius of San Roque ; belly a trifle whiter, hind feet seeming to lack dusky ankles of San Roque series. It is possible that the Asuncion animal is a slightly character- ized subspecies of maniculatus distinct from cineritius, but a larger series of specimens from Asuncion as well as from San Roque is needed to establish this point. No apparent skull differences." 19. Peromyscus maniculatus magdalenae. Magdalena White-footed Mouse Common on Magdalena Island. 20. Neotoma intermedia intermedia. Intermediate Wood Rat Common about San Quintin Bay. 21. Neotoma intermedia pretiosa. Matancita Wood Rat Quite common on both Magdalena and Margarita islands. 315 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Sm. 22. Neotoma bryanti. Cedros Island Wood Rat Neotoma were found more or less abundantly in all parts of Cedros Island, more common in the northern end and among the more broken parts of the island and rather scarce at the south end, where the land is lower and less suited to their requirements. 23. Epimys rattus alexandrinus. Roof Rat A specimeil taken on the west side of San Quintin Bay op- posite the settlement. At some time within the past two years a large steamer was wrecked on San Roque Island, evidently introducing rats at that point, as a dead Epimys was seen on the beach. 24. Mus musculus musculus. House Mouse Mice of this genus are more or less distributed over Guada- lupe Island and, as they are more abundant in the sections ad- jacent to the fur-seal rookeries, it is not improbable that they were introduced by the Russians a century or more ago. A single immature mouse was shot at Jacks Bay on the west side of the island. If this specimen represents the normal color of the race at present found on Guadalupe, it is a very interesting illustration of evolution. The upper parts are a rich brown, several shades darker than any specimen in the collection of the San Diego Museum of Natural History; below, somewhat lighter. It will be better, however, to await further specimens before separating the race. 25. Perognathus helleri. Heller's Pocket Mouse The type of this species was taken at San Quintin, where pocket mice are quite common. For some reason they were Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 317 very hard to trap at the time of our visit, and but two were secured, both from the west side of the bay. 26. Perognathus penicillatus albulus. Magdalena Island Pocket Mouse At Magdalena Bay we found this race not uncommon, but owing to the ants destroying the specimens only two w^ere secured in condition worth saving. 27. Perognathus anthonyi, Anthony's Pocket Mouse For the past quarter of a century this species has been rep- resented by the single type in the collection of the Biological Survey, collected by the present writer at South Bay, Cedros Island. During the summer of 1922 we found the species rather commonly distributed over the island, from the sandy arroyos at the beach to the rocky hillsides nearly or quite, to the tops of the higher mountains. For some reason, this species was very difficult to secure in traps and only six speci- mens were taken. The series, however, shows a very inter- esting condition of moult, which is perhaps best expressed in Dr. Nelson's letter regarding the series : "The specimens of Perognathus from Cedros Island have been compared with the type taken by you at South Bay many years ago. One of these from the west side of Cedros Island, like the others from South Bay, agrees closely with the type. These specimens in fresh pelage are, however, nearly through- out more blackish, less brownish, than the tyj>e, which is in a worn and somewhat faded pelage. In one of your examples, however, the pelage change is evidently progressive, beginning on the anterior part of the body. The brownish rump and hind legs still in worn pelage very closely resemble the faded pelage of the type, showing that the apparent difference in general color is only seasonal. These specimens of Perognathus an- thonyi are of considerable interest, as, up to the time of this second collection, the type had remained unique." 313 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. The work of this species so closely resembles the hills that mark the burrows of Thomomys that for many years I have felt certain that there was a species of that genus to be found on Cedros Island. Dr. Hanna, though experienced in collect- ing pocket gophers, was also misled by the many "dumps" along the gulches and it was not until we had dug into several of the burrows and unearthed a pocket mouse that we reluc- tantly agreed that we had been deceived. 28. Dipodomys merriami parvus. San Bernardino Kangaroo Rat Not uncommon at San Quintin. Three specimens. 29. Dipodomys platycephalus. One night was devoted to the traps at Abreojos Point, but, though signs of Dipodomys were noted in several places, no specimens were taken. An owl pellet, which was found near the beach, contained the skull and bones of the above species. 30. Ammospermophilus leucurus peninsulae. Lower California Ground Squirrel Common on the plain east of San Quintin, where two were secured, July 20. 31. Lepus calif ornicus martirensis. San Pedro Martir Jack Rabbit Two jack rabbits taken at San Quintin in July are somewhat puzzling. If one is to judge from the coloring as given in Nelson's "Rabbits of North America," tliev would be classed as martirensis, to which form I have provisionally assigned them ; though the measurements agree more closely to those of hennettii. Vol. XIV] ANTHONY— THE BIRDS AND MAMMALS 319 32. Lepus californicus magdalenae. Magdalena Island Jack Rabbit On the west side of Margarita Island we found this strongly marked race rather common, but not easily collected owing to its keeping largely in the thick growth of underbrush found along this side of the island. A half-grown young was shot July 29. ' 33. Sylvilagus bachmani cinerascens. Ash-colored Cottontail A single specimen of the brush rabbit from San Quintin I have regarded as this race. There is nothing to distinguish it from specimens taken at San Diego, either in color or measure- ments, though the locality is well within the range of exiguus and considerably south of recorded capture of cinerascens. 34. Sylvilagus bachmani cerrosensis. Cedros Island Cottontail Two specimens of this species were secured from Cedros Island. 35. Odocoileus cerrosensis. Cedros Island White-tailed Deer We found this deer fairly common on Cedros Island, though since its discovery a quarter of a century ago it has been re- duced to the point of extinction by mining operators that de- pended upon venison to furnish meat the year round for a large force of workmen. The last company working the mines at the north end of Cedros is said to have left several dogs that have multipled until at this date several large packs are roaming the island and killing many does and fawns. In August we secured several specimens and saw others. 320 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. 36. Antilocapra americana peninsularis. Lower California Antelope Formerly quite abundant from San Quintin south to Turtle Bay, but reduced at this writing to but a remnant of its former numbers, due chiefly to hunters hired by American corporations operating mines and quarries within the range of the species. The only evidence we found was a horn, from a recently killed animal, at Abreojos Point. PROCEEDINGS OF THE CALIFORNIA ACADEMY OF SCIENCES Fourth Series Vol. XIV, No. 14, pp. 321-343. September 5, 1925 XIV EXPEDITION TO GUADALUPE ISLAND, MEXICO, IN 1922^ THE COLEOPTERA BY FRANK E. BLAISDELL, Sr. This report covers the Coleoptera taken by the expedition of the CaHfornia Academy of Sciences to Guadalupe and other islands off the west coast of Lower California in July and August, 1922. This expedition was made possible through the courtesy of the Mexican Government, which placed its fish- eries patrol boat Tecate at the services of the Academy and the San Diego Society of Natural History and collaborated with those institutions in the work of the expedition. No entomologist accompanied the party, but a very good series of insects was secured through the efforts of Dr. G. Dallas Hanna and Mr. Joseph R. Slevin, who devoted as much time to this work as they could spare from their other duties. The fact that 14 new species and a good series of other rare beetles were taken fully justifies the effort made. 'This paper is No. 3 of the Tecate expedition. No. 1, the Narative, gives a complete itinerary. See this volume, pp. 217-275. September 5. 1925 322 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. List of the Species Taken 1.

September 5, 1935 326 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. 21. Rhagodera laticeps Blaisdell, new species Form elongate, a little more than three times as long as wide, slightly wider posteriorly and moderately convex. Color nigro-piceous and usual- ly more or less covered by a grayish coating. Head nearly quadrate, slightly dilated anteriorly and coarsely punctate ; front with or without impressions, when distinct noticeable along the frontal suture, on vertex and broadly and feebly within the eyes ; super- ciliary ridge acute but not raised above the eyes as in costata; sides of front obliquely emarginate at oblique suture. Pronotum broader than long, sides arcuate anteriorly, becoming broadly sinuate, convergent, straight or parallel to base, where the angles are subrectangular and slightly prominent posteriorly; sides feebly denticu- late ; disk strongly bicostate, costae scarcely arcuate and parallel. Elytra oblong, slightly widest behind ; humeri subrectangnjlar ; sutural, marginal and the discal costae entire and subacutely elevated; intervals with two rows of large, coarse, but not strongly impressed punctures. Body clothed with short scale-like hairs. Length (type) 7.5 mm. ; width 2.4 mm. Type: Female, No. 1680, Mus. Calif. Acad. Sci., collected by Hanna and Slevin, August 13, 1922, on San Benito Island. Paratypes, 12 females in the Academy collection and in that of the author. R. laticeps varies in size just as tuberctUatus does; it is no larger and is distinct from both that species and costatus. Horn's description of costatus is too meager and unsatisfac- tory ; he states that it is more depressed than tuherculatus, with all the costae more prominent and with deeper interstitial punc- tures. This is not so with laticeps, for the costae and inter- stitial punctures are less strongly marked, the elytra are widest behind the middle ; the basal angles of the pronotum are really a little more than rectangular, but I do not consider them acute and posteriorly produced as Horn states of costatus. R. laticeps is much less rough and less strongly sculptured than tuherculatus. From Horn's description I drew the in- ference that costatus is as strongly or more strongly sculptured than tuherculatus. 22. Melanophthalma distinguenda Com, Four specimens, all taken at N. E. Landing on Guada- lupe Island, July 11, by Hanna and Slevin. Vol. XIV] BLAISDELL—THE COLEOPTERA 2>27 23. Scymnus guadalupensis Blaisdell, new species Form moderately broadly oval, slightly narrowed anteriorly. Abdominal post-coxal arc normal, not quite attaining the apical margin of first seg- ment, arcuate throughout, curving forward externally and attaining the basal margin of the segment. Presternum rather wide and feebly con- vex between the coxae ; carinae feeble and converging slightly anteriorly, entire, intervening surface glabrous. Body bicolored, pale above and somewhat nubilate. Pubescence sparse, short, pale flavate in color and irregularly directed. Color beneath deep black; legs rather dark luteo- fiavate; head, pronotum and elytra, more or less castaneous. Head piceo-castaneous, front plane, finely and sparsely punctate. Pronotum transverse, sides discontinuous with those of the elytra, feebly arcuate and parallel; base lobed at middle third, thence obliquely and very feebly arcuate; disk blackish in central and basal two-thirds and narrowly so along the apical margin behind the head, punctures sparse and slightly coarse. Elytra narrowly black on the sutural margins, and very indefinitely clouded on each elytron near the base ; punctures scarcely coarse and sparsely placed, finer along the suture. Scutellum black. Beneath densely and rather coarsely punctate, including the post-coxal plate. Length 2 mm.; width 1.5 mm. Type: No. 1681, Mus, Calif. Acad. Sci., collected by Mr. Slevin, July 17, 1922, at the South Anchorage, Guadalupe Island. Fall, in his "List of the Coleoptera of the Southern Cali- fornia Islands," does not mention a sing-le species of Scymnus as having- been taken on Guadalupe Island. The single speci- men at hand is well preserved and surely does not agree with anything mentioned by Casey in his "Revision of the American Coccinellidae, nor apparently with any species given in the Biologia. S. guadalupensis resembles nehulosiis at first sight. Its color is darker, the post-coxal lines are complete, the prosternum is less convex and the carinae feeble and more widely separated, with the intervening surface glabrous. In nebiilosus the post- coxal lines are incomplete, the prosternum more convex, cari- nae stronger and more evidently converging anteriorly with the intervening space narrower. 328 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. 24. Coccinella califomica Mann. Nineteen specimens. Guadalupe Island, July 11-15, col- lected by Hanna and Slevin. 25.

Head rather coarsely and confluently punctate; deflexed epistomal lobe triangular, line forming the upper margin of the deflexed portion not strong and, as usual, continuous with the sides of the front when viewed from above ; mandibular tooth subapical. Antennae long and slender, tenth joint attaining pronotal base. Pronotum transverse and moderately convex ; apex truncate in moder- ate circular arc ; apical angles rectangular and subacute ; sides broadly arcuate, slightly straighter posteriorly than anteriorly, margin acute but not noticeably beaded; basal angles obtuse and distinct; base slightly sinuate laterally ; disk densely but not very coarsely, and more or less confluently, punctate; punctures rather discrete along the lateral margin.

Paratypes, same data and from East and West San Benito Islands, August 12, 13, 1922. 106 specimens studied. In 5". piincticollis the elytral series of coarse punctures are entire and attain the apex. In zvillmmsi the series become ob- solete on the apical declivity as in Triorophus. In hannai the form is narrower in both sexes and not in the least inflated, punctuation of head and pronotum coarser and more evidently coalescent; punctuation of abdomen stronger. 6*. sparsa is more polished, the pronotal punctures discrete and well separ- ated and basal angles of pronotum very small and acute. 6*. opaca is very different in its dull surface and convex elytral intervals. 29. Stibia hannai Blaisdell, new species Form elongate suboval, elytra not inflated and strongly convex. Color nigro-piceous ; legs and antennae ruf o-piceous ; luster shining, head and pronotum slightly duller, surface glabrous.

S. hannai differs distinctly from williamsi in its narrower and more elongate form, and coarser punctuation of head and pronotum; elytral striae less abbreviated on apical declivity than in williamsi. Other differential considerations are given under the latter species. 30. Centrioptera spiculifera Lee. This species occurs on Santa Margarita Island, where a single specimen was obtained by Hanna and Slevin July 29. 31. Centrioptera pectoralis Blais.

Middle of first abdominal segment with a small tubercle, the latter slightly raised and rounded, surrounding surface not noticeably more punctate. Posterior femora with a moderately slender acute tooth, about three times as long as wide at middle, edges very finely denticulate, especially posteriorly. Female usually smaller than male. Edges of tibial groove of posterior femora, finely denticulate in distal half. Length (types) 13-12 mm. ; width 4.2-3.9 mm. Type: Male, No. 1686, and allotype, female, No. 1687, Mus. CaHf. Acad.

About 38 specimens studied. The males of the several species present differential charac- ters as follows : A. inconstans has a truncate epistomal apex and rufous legs, the femoral teeth are long; in cequalis the femoral teeth are truncate at tip and the epistomal apex arcu- ate; cbcnina has black legs (sometimes rufous), the epistomal apex truncate and the elytra more smoothly sculptured, nitida has three equidistant teeth on hind femur, while in costipennis the elytra are sulcate and the femoral teeth are large, acute, with finely denticulate edges; alutacea has the teeth bifid and the edges finely denticulate, while bicolor has two small, acute and exactly equal teeth which are widely separated. 332 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser, 34.

E. adumbrata belongs to the eschscholtzii group of the sub- genus Eleodes and should follow inUata in our lists. It differs from all others of the group by the fine, equal elytral punctu- ation ; in the typical form, the elytra are subcostate. 39. Eleodes discincta Blaisdell, new species This species is closely related to adumbrata, but differs mainly in the flat elytral intervals; strial punctures usually slightly larger than the interstitial, and never as coarse as in luccB or inflata. Otherwise it is similar to adumbrata. It also belongs to the eschscholtzii group and should follow adum- brata in our lists. It also presents greater variation in size 034 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. and the males are markedly elongate, somewhat resembling the same sex in longicollis and gigantea.

E. discincta occurs also on the mainland at San Quintin if two females in the author's collection are correctly labelled. I believe these specimens were taken on a former expedition sent out by the California Academy of Sciences to the Galapagos Islands in 1905-6, and were collected by Mr. F. X. Williams. 40. Eleodes inepta Blaisdell, new species Form elongate, subfusiform oval, about three times as long as wide, moderately convex. Color deep black, very dull in luster and alutaceoits. Head rather small, short before the post-ocular line; front convex, finely, sparsely and irregularly punctate, each puncture with a small fer- ruginous hair; sides of the front feebly arcuate and convergent anteriorly, apex of the epistoma truncate and the angles obtuse and somewhat rounded. Eyes small. Antennae slender, joints less elongate than in armata and less stout than in militaris, not in the least incrassate.

Sci., collected by Hanna and Slevin, August 1, 1922, on Angulo Rock, Asuncion Island. E. inepta is described from a unique. It is sufficiently dis- tinct from all other members of the armata group. From the standpoint of analogy, it is expected that inepta will vary as regards the size and sculpturing of individuals. It is to follow armata in our lists. 41. Eleodes morbosa Blaisdell, new species Form suboblong-ovate to ovate, about twice as long as wide, resembling certain forms of omissa of the subgenus Melaneleodes. Q)lor black, some- what piceous, especially the appendages ; luster moderately shining, head and pronotum somewhat alutaceous. Head relatively moderate in size ; front slightly convex, sparsely and finely punctate, frontal suture more or less evident, surface slightly im- pressed within the supra-antennal convexities where the punctures are somewhat denser. Eyes and posterior canthi a little more prominent than the sides of the front, which are convergent anteriorly, epistomal apex truncate, or very feebly sinuate. Antennae comparatively slender and moderate in length, terminal three joints slightly incrassate and slightly transverse; joints four to eight inclusive a little longer than wide, the eighth being subtriangular. Pronotum about a fifth or a fourth wider than long, widest slightly in front of the middle ; apex slightly and broadly emarginate between the anterior angles, which are subacutely rectangular and slightly promi- nent anteriorly ; sides broadly and rather strongly arcuate from apex to base, but less so behind the middle, marginal bead fine; base broadly and feebly arcuate; basal angles obtuse, not rounded and deflexed; disk moderately strongly convex, feebly and narrowly impressed along the sides within the bead, evenly declivous antero-laterally, punctures very fine and rather widely separated, evenly distributed. Elytra oval, base truncate and equal to the pronotal base, humeri obtuse but distinct; sides evenly and broadly arcuate, somewhat oblique to apex in apical third, apex quite narrowly rounded; disk rather strongly convex, 336 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. slightly less so on the dorsum, rather arcuately declivous posteriorly; punctures moderately small, closely placed in unimpressed striae, and more widely spaced interstitial series ; punctures becoming more or less con- fused laterally and on the apex where they are finely but distinctly muricate. Abdomen rather finely and not densely punctate. Legs moderate and relatively short, rather densely sculptured and sparsely clothed with fer- ruginous setae. All of the femora armed ; tooth of the anterior femora small and acute, of the middle and posterior femora small and obtuse; all of the tibiae slightly arcuate, especially in basal third. Males : Narrower. Abdomen less convex and impressed along the middle of the first three segments. Plantar grooves open on all the tarsi. Elytra somewhat more obliquely declivous posteriorly.

E. morbosa is a very unique type in the fauna of the western coast, as it has more of the facies of a Melaneleodes than a member of the armata group of the subgenus Eleodes. All of the femora are armed. It agrees with certain species of the Mexican fauna in these respects, but its true relation to the armata group cannot be determined until some of the Mexi- can species have been carefully studied, especially as regards the genitalia ; it may have to be placed in a different section of the armata group. 42.

Ccelocnemis slevini Blaisdell, new species Form elongate, rather strongly convex. Color deep black, shining; surface glabrous. Head moderately large, widest between the antennae, thence convergent and straight anteriorly to the epistomal apex, the latter truncate, angles obtuse and slightly rounded ; front impunctate, with few vague impres- sions, frontal and oblique sutures more or less evident. Eyes not in the least prominent, just noticeably convex. Antennae short, attaining about the basal third of the pronotum, slightly and gradually clavate, distal five joints compressed, eleventh widest. Pronotum about a fourth or less wider than long, widest near the middle ; apex truncate in rather moderate circular arc ; apical angles quite broadly rounded into the sides, which are rather strongly and evenly arcuate before the middle, thence convergent and more or less broadly and rather feebly sinuate to the base, marginal bead very fine ; base trun- cate and more or less obsoletely margined ; basal angles obtuse to rec- tangular and perfectly distinct; disk moderately strongly convex, im- punctate and sculptureless ; rather more strongly declivous antero-laterally, more so postero-laterally in about basal fourth, where it appears slightly compressed. Elytra oblong-oval, usually widest behind the middle, strongly convex, moderately less so and slightly depressed on the dorsum ; base truncate, not wider than the pronotal base ; scutellum small and triangular ; humeri very obtuse and rounded ; sides broadly and quite evenly arcuate, rather less so anteriorly, apex oval ; disk rather obliquely and arcuately declivous posteriorly, with eight rows of unimpressed and fine punctures, which are rather unevenly spaced in the series ; a ninth or marginal row is present against the margin throughout the length ; series rather less evident on the apical declivity ; intervals impunctate in the specimens at hand. 338 CALIFORNIA ACADEMY OF SCIE^CES [Proc. 4th See. Body beneath obsoletely sculptured ; abdomen somewhat rugiilose. Legs moderately long ; middle and posterior femora rather slender ; obsoletely sculptured. Male: Narrower; sides of the pronotum more broadly and evenly arcuate, not subangulate at middle; abdomen less convex and more strongly oblique to the sterna. Female : broader and more evidently widest behind the elytral middle ; pronotal sides subangulate, rather more sud- denly and broadly sinuate posteriorly ; abdomen subhorizontal.

Paratypes, same data, in the collectioil of the Academy and in that of the author. Described from five specimens. After much study and deliberation, by comparing the above small series with nearly a thousand specimens from all parts of the Pacific Coast, Nevada and Arizona, I came to the con- clusion that slevini is a distinct species. It resembles magna more than any other ; in the female, however, the pronotal sides are subangulate with the disk slightly depressed at that point. It is not closely related to dilaticollis or obesa. 48. Cratidus rotundicollis Horn Five specimens of this rare species were taken on Cedros Island, August 7, and on Asuncion Island at Angulo Rock, August 1, by Hanna and Slevin. 49.

Helops guadalupensis Casey This fine species was secured on Guadalupe Island, July 15 and 17 at the South Anchorage, by Mr. Slevin. Vol. XIV] BLAISDELL—THE COLEOPTERA 339 51. Helops benitensis Blaisdell, new species Form elongate oval, subparallel, about two and a half times longer than wide. Color black; legs and antennae dark rufo-piceous ; luster shining. Head densely and deeply punctate, punctures moderately coarse and more or less confluent; sides convergent anteriorly, emarginate at the ob- lique suture ; epistoma truncate at apex, surface impressed on the frontal suture and along the sides to the apical margin of the epistoma. Eyes not more prominent than the sides of the front. Antennae slender, third joint about equal to combined length of fourth and fifth; joints 4 to 8 longer than wide, subequal in length; terminal four joints compressed and gradually incrassate. Pronotum about as wide as long, widest at middle; apex slightly arcu- ate in moderate circular arc; sides broadly arcuate, rather more strongly so in middle third, marginal bead fine; angles obtuse; base subtruncate; disk not impressed, densely and evenly punctate, punctures moderately coarse and coalescing slightly. Elytra oval, base slightly bi-marginate ; scutellum very short and trans- verse, entering very slightly between the elytra; humeri obtuse and dis- tinct ; sides evenly and broadly arcuate, apex rather broadly rounded ; disk striato-costate, intervals convex, especially on the apical declivity, strial punctures rather coarse, closely placed and rather deep, striae not impressed ; intervals very finely punctulate ; no interstitial tubercles on sides or apex. Propleura rather coarsely punctate, with more or less coalescence. Abdomen moderately convex, finely and rather sparsely punctate, each puncture with a fine recumbent hair. Legs slender and relatively short ; anterior tarsi noticeably dilated and clothed beneath with pale hair densely placed ; middle and posterior tarsi with similar hair but arranged along the margins and at apex of the joints. Length 10 mm. ; width 4 mm. Type: No. 1697, Mus. Calif. Acad. Sci., collected by Hanna and Slevin, August 13, 1922, on Middle Benito Island. Very distinct from any species of Helops known to me. At first there was some doubt as to whether or not it was a Helops. It answers to the generic test. The front is not as widely dilated as in other species and not or scarcely more prominent than the improminent eyes, covering base of mandibles as usual ; clypeus short, coriaceous. The striato-subcostate elytra is rather unique. 340 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. 52. Catorama pusillum Lee.

Ipochus insularis Blaisdell, new species Form elongate oblong-oval to slightly oblong-ovate, strongly convex. G)lor black to nigro-piceous and more or less shining. Pubescence abun- dant. Surface clothed throughout with erect, soft, pale, moderately long hairs that are very sparsely scattered ; and coarser, recumbent, somewhat fulvous hairs ; these latter densely but unevenly distributed, forming a pattern, particularly on the front and vertex of the head and peripheral parts of the pronotal disk, and a rather broad parasutural stripe on the apical declivity of each elytron, besides irregular and anastomosing patches on the disk, leaving a central oblong glabrous area across the suture in basal half. Antennae densely clothed with a very fine appressed pile. Ab- domen with moderately long hairs ; distal half of femora clothed with pale fulvo-cinereous hairs with intermixed small black spots, tibiae more or less densely invested with similar hairs and with tuft of fulvous hair on outer surface in apical third. Head moderately convex, with few scattered punctures and a fine median impressed line ; f ronto-epistomal line transverse and rather promi- nent. Antennae about as long as body. Prothorax subglabrous, cylindrically convex and nearly as long as wide, base and apex truncate, sides moderately arcuate ; surface with very small, closely placed punctures, and larger and sparsely placed asperities, espe- cially on the sides and across the apex. Elytra about twice as long as wide, or slightly less, and oblong-sub- cylindrical in form, more or less abruptly declivous posteriorly ; disk with sparsely placed asperities. Body finely sculptured beneath. Legs moderate ; femora moderately and gradually clavate, the anterior less so. Male : Elongate oblong-oval and subcylindrical, elytra scarcely wider than the prothorax. Female : Elongate oblong-ovate, usually slightly flattened on the elytral disk; elytra somewhat widest behind middle and slightly wider than prothorax. Length (types) 10.5 mm.; width 3.5-4.5 mm.

The most salient characters are its large size and distinct elytral asperities. The distribution of the elytral pubescence is dis- tinctly different in pattern from that seen in fasciatus, where it forms transverse fasciae. 55. Estola sordida Lee.

Ortholeptura insignis Fall One example of this fine species was found on Guadalupe Island, July 15, by Hanna and Slevin. Plenaschopsis Blaisdell, new genus This new genus differs from Trigonoscuta chiefly in having the corbels of the metatibise obscurely defined externally by spines, surface of corbel convex in its anterior half and covered with short, thick and obtuse spines or scales ; sinuate posterior- ly, with the outer angle prolonged and obtuse ; corbels closed off from the articular cavity by a row of spines which are not closely placed ; articular cavity not scaly as in Trigonoscuta. Genotype, Plenaschopsis pilosisquajna Blaisdell, new species. The following characters are common to both genera : Ocu- lar lobes absent, antennal scrobes lateral and directed inferior- ly; third joint of all the tarsi wider than second and deeply lobed ; anterior tibiae dilated at tip ; antennal scape long, passing the eyes. General fomi and appearance that of Trigonoscuta. The tribe Trigonoscutini, as defined by Pierce, must be revised so as to include the present genus. A tabular statement of the differences between the two genera may be given as follows: 342 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Metatibial corbels closed. Corbels concave; external angle not produced; articular cavities strongly cavernous and scaly Trigonoscuta Motsch. Corbels convex anteriorly, feebly defined laterally, sinuate, with the external angle produced; articular cavities not deeply cavernous and not scaly Plenaschopsis, n.g. 57. Plenaschopsis pilosisquama Blaisdell, new species Form oval, less elongate than Trigonoscuta pilosa Motsch., robust, slightly more narrowed anteriorly than posteriorly. Color black, legs nigro-piceous, tarsi slightly lighter; surface densely covered with cinere- ous and plumbeo-'cinereous scales, scarcely variegated in the type and clothed with sparsely placed, nearly erect greyish hairs; scales of two kinds, one round or oval as in T. pilosa, the other oval and villous or covered with minute filaments so as to appear shaggy. Head and rostrum as long as the pronotum. Rostrum suboblong, dis- tinctly narrower than the head and separated from it by a fine transverse subangulate line; upper surface finely canaliculate, tip truncate; scrobes deep and arcuate, with the superior margin distinct to and passing near the lower margin of the eyes, the latter oval, slightly oblique. Antenna moderately long; scape almost gradually clavate, passing beyond the eyes posteriorly; funicle seven-jointed, first three obconic, first and second elongate, first nearly three times as long as wide, second slightly more than twice as long as wide; third a little longer than wide; four to six as long as wide and subglobular ; seventh larger and about as long as the sixth and twice as wide as long; club oval. Front finely canaliculate be- tween the eyes. Pronotum a little broader than long, narrower in front; sides strongly arcuate, subapical impression very feeble; apex arcuate, slightly sinuate at middle ; disk strongly arcuate from side to side, and suddenly and very briefly declivous before the base in middle two fourths, rather coarsely and closely punctate. Elytra broadly oval, rather less than a third longer than wide ; scutellum small and triangular; humeri broadly rounded; sides broadly and rather moderately strongly arcuate; disk strongly convex, rather abruptly and arcuately declivous posteriorly, with rows of rather fine punctures, which are very slightly impressed. Body beneath not densely scaly; third and fourth abdominal segments equal in length; hairs sparse and rather long; scales of the under surface nearly all shaggy as they are on sides of pronotal disk, and on sides, base and apex of the elytra, with a few similar ones above the eyes ; elsewhere the scales are round or slightly oval. Legs not closely scaly, hairs quite long and flying. Length 6.6 mm. ; width 4 mm. Vol, XIV] BLAISDELL—THE COLEOPTERA 343 Type: Female, No. 1817, Mus. Calif. Acad. Sci., collected by Dr. Hanna, August 3, 1922, on Natividad Island. In pilosisquama the peculiar shaggy scales, less widely open antennal scobes just before the eyes, antennal joints four to six subglobular, and the different corbels of the hind tibiae will amply distinguish this species from Trigonoscuia pilosa, which it resembles in most all other characters.

D. A. COCKERELL University of Colorado 1. Anthidium angelarum Titus Females: Colton, May 26-28 (Van Duzee) ; hills back of Oakland, May 8 (Van Dyke) ; Santa Monica (F. C. Clark) ; Stone Caiion, Monterey Co., April 21 (Van Duzee) ; Poway, San Diego Co., June 10 (Blaisdell) ; all in California. Males: Cisco, July (Mrs. H. E. Ricksecker) ; Meadow Val- ley, 3500-4000 ft., June 5 (Van Dyke) ; Poway, San Diego Co., May 31 (Blaisdell) ; South Sonoma Co., July 1 (Kusche) ; all in California. 2. Anthidium nebrascense Swenk Swenk described this (1914) from Nebraska and Wyoming. The following year he recorded it from Truckee, Calif. The Californian specimens before me show variation, but they agree so closely with the description of A. nebrascense that I do not know how to separate them. They are close to A. titusi Ckll., but the end of the abdomen is different. Males: Panoche Canon, Fresno Co., April 29 (Van Dyke) ; Colton, May 26-28 (Van Duzee) ; Poway, San Diego Co., May 16 (Blaisdell); hills back of Oakland, May 15 (Van September 5, 1925 346 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Dyke) ; Santa Monica (F. C. Clark) ; Stone Canon, Monterey Co., April 21 (Van Duzee) ; all in California. The only female which seems likely to belong to these males is the one which I have identified as A. emargitiatum atripes Cresson, but the type (male) of atripes is certainly not nebras- cense. I must leave the final decision about the supposed atripes to those who can study the species in the field. The black scutel- lum of the nebrascense males certainly argues against their association with the supposed atripes; but Swenk has what he regards as female nebrascense from Wyoming, and it had two linear marks on scutellum. 3. Anthidium hcsperium Swenk Females: Mokelumne Hill, October (Blaisdell) ; San Diego (Blaisdell); Millbrae, San Mateo Co., .Sept. 1 (Blaisdell); Cr3^stal Lakes, San Mateo Co., June 25 (Van Duzee) ; all in California. The first abdominal segment usually has an inter- rupted band instead of four spots, but the insect agrees other- wise with Swenk's description, based on females from Palo Alto and Pacific Grove. The male is unknown. The species seems to belong to late summer and early fall, the earliest date being June 25, the other known dates in July, September and October. 4. Anthidium atriventre Cresson Females: Meadow Valley, Plumas Co., Calif., 6000-7000 ft., June 17 (Van Dyke) ; Sparta, Baker Co., Oregon, July 2 (Van Dyke). Cresson described it from California (Hy. Edwards). 5. Anthidium titusi Cockerell Males: Kings River Canon, Fresno Co., Calif., July 3 (Van Dyke) ; Huntington Lake, Fresno Co., Calif., 7000 ft., July 4 (Van Duzee). These specimens have the scutellum entirely black. The Kings River Canon specimen has hair of head and thorax above pale fulvous. The reference of these California insects to A. titusi must be considered provisional, or at least Vol. XIV] COCKERELL—ANTHIDIINE BEES 347 tlK.v may be racially distinct. However, the form and structure agree well. 6. Anthidium blanditum Cresson Female: South Fork Kings River, Fresno Co., Calif., July 8 (Van Dyke). This is smaller than Cresson's type, and has two elongate black marks on clypeus, no spot beneath tubercles, abdominal bands on segments 2 to 4 narrowly interrupted, and the femora rather differently marked. I assume that it represents only a variation, but more material is desirable. It is readily known from angelicum by the angulation at sides of last segment. The abdominal bands are broad and deep yellow. 7. Anthidium fresnoense Cockerell, new species Female : Length about 8.5 mm. ; robust, black, head and thorax with white hair, pure white on thorax above ; eyes bluish green, black at lower end ; head entirely black, including mandibles, except a round yellow spot above each eye ; mesothorax very densely punctured ; large mark on tegulse in front, very small one behind, end of the obtuse tubercles, and elongate marks on axillae and scutellum, yellow ; scutellum depressed in middle posteriorly ; legs black, the tibiae with yellow stripes, not reach- ing the apex; hair on inner side of hind basitarsi black; wings dusky, second cubital cell long; abdomen with five lemon-yellow bands, and on first segment four marks, the outer ones large and quadrate, the inner consisting of transverse stripes ; bands on segments 2 to 6 all narrowly interrupted and emarginate at sides anteriorly ; ventral scopa dark gray- brown, white anteriorly and at sides. Differs from A. palliventre Cress, by the scutellum, axillae and tibiae being conspicuously marked with yellow. The lemon- yellow abdominal bands at once separate it from A. teituiflorde Ckll.

Anthidium mormonum Cresson, and allies In 1878 Cresson described this species from a single male obtained by Ulke in Utah. In 1879 he described A. blanditum, based on a couple of females collected by Morrison in Nevada. In 1904 I described A. pecosense and A. hernardinum, the lat- ter with three varieties. In 1911 I remarked, "The female of A. pecosense so nearly agrees with the description of A. blandi- tum from Nevada as to suggest that the two represent varia- 352 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. tions or races of one species." Swenk in 1914 made the com- bination A. blandituni pecosense (CklL). Certainly we have here a group of very closely allied forms, difficult to classify correctly. The relatively large A. hcrnardinnm, with rich orange markings, the apical lobes of the male abdomen very broad, the axillae orange, and other good characters, may be set aside as distinct. A. ariduni (A. beniardinum aridtim Ckll.) is certainly distinct from the others by the pointed apical lobes of the abdomen, scape yellow in front, entirely black axillae, etc. Three males from Beaver Creek, Kamas, Utah, July 4, 1922 (Van Duzee), must be referred to A. pecosense, though the apical lobes of abdomen are variable, in one specimen spreading instead of parallel. The hair of thorax above is fulvous ; the axillae have small yellow spots ; the yellow of anterior tibiae is continuous. These differ from A. mormonnm by the fulvous dorsal pubescence, the large discal spots on first abdominal segment and the more spreading apical lobes of abdomen, with broader and shallower sinus between lobes and median spine. It is thus unsafe to assert that mormonnm and pecosense are one species, though it may be that they will prove inseparable, or only racially distinct. The males described from California as varieties fragariel- lum and zvilsoni of A. beniardintini belong rather to the mor- monum-pecosense-hlanditiim alliance, as shown by the apical lobes of abdomen and the merely spotted axillae. They evi- dently represent a single species, but the dorsal hair of thorax is white in fragariellnm, yellow-fulvous in ivilsoni. The zvilsoni form is represented by three males from Meadow Valley, Plumas County, California, 4000 ft., June 8 and 15 (Van Dyke), except that these have the yellow on anterior tibiae interrupted, whereas in typical zvilsoni it is continuous. The fragariellnm form is represented by males from Meadow Val- ley, 3500-4000 ft.. June 21 (Van Dyke) ; South Fork Kings River, Calif., July 8 (Van Dyke), and Fallen Leaf Lake, Calif., July (L. S. Rosenbaum). The last has the yellow on anterior tibiae interrupted, but it is entire on the other two, and also in typical fragariellnm. These California males run smaller than A. pecosense and have more yellow on apical segment of abdomen. In the type Vol. XIV) COCKERliLL—ANTHIDIINE BEES 353 of fragaricllum, but not in the others, the yellow on first seg- ment of abdomen consists of a pair of large cuneiform patches, deeply incised posteriorly. This also has large yellow patches on anterior and middle femora, but the series shows that these vary. I conclude that the Californian insect is a valid sub- species of A. pecoscnse. The name fragaricllum is to be pre- ferred over zvilsoni, having priority where it is first printed, in the table published May, 1904. Coming now to the females, we fortunately have a couple from Meadow Valley, 3500 to 4000 ft., June 8 and 21 (Van Dyke), certainly belonging with the males just recorded. The one of earlier date has hair of head and thorax above deep ful- vous ; in the other it is much paler but not white. In both the clypeus is entirely yellow. This insect agrees with the descrip- tion of A. blanditiim except for the fact that there is a large oblong yellow patch on mesopleura, and perhaps also in the more fulvous dorsal pubescence. The patch on pleura seems to be of little importance because a female of the same species from Fallen Leaf Lake, California, June 26 (Van Dyke), has the mesopleura entirely black. The same is true of one from Guerneville, Sonoma Co., Calif., May 30 (Van Dyke). These with black pleura have the hair of head and thorax above strongly fulvous. The female of A. pecosensc, as identified by me from Flagstaff, Arizona, differs from the above Californian females in being larger, in having the mesopleura black, and yellow only bordering the tubercles ; the dorsal hair is red. A female from Strawberry Valley, California (Davidson), which I ascribed to A. hernardinum, is small and agrees in all essen- tial particulars with the one from Fallen Leaf Lake. It is better referred to A. fragaricllum. Thus the whole series discussed will stand for the present thus : A. bcrnardimim Ckll. A. aridum (Ckll.) A. mormonitm Cresson A. blanditmn Cresson ( ?? of mormonum.) A. pecoscnse Ckll. ( ? var. of inormonum-\-blanditiim.) A. pecosensc fragaricllum (Ckll.) {'^^^^blanditum.) A. pecoscnse fragaricllum var. zvilsoni (Ckll.) (apparently not a valid race). 354 CALIFORNIA ACADEMY OF SCIENCES [Peoc. 4th Ser.

Anthidium tricuspidum Provancher California: Mokelumne Hill, June (Blaisdell) ; Crystal Lakes, San Mateo County, June 25 (Van Duzee) ; Cazadero, September 2 (Van Duzee). San Diego, Calif. (Blaisdell), male. Oregon: Crater Lake, 7000 ft.. July 16 (Van Dyke). 16. Anthidium bernardinum Cockerell California : Mill Creek Caiion, San Bernardino Co., Septem- ber 21 (Van Duzee). The males are variable; hair on thorax above white or fulvous; scape practically all black or with a large yellow mark. 17. Anthidium emarginatum atripes Cresson The following females differ from typical A. emarginatum in having the tibiae entirely black. I can refer them only to Cresson's atripes, based on a male from Nevada. California: Huntington Lake, Fresno Co.. 7000 ft., July 4 and 27 (Van Duzee) ; Meadow Valley, Plumas Co., 3500 ft., June 21 (Van Dyke) ; Blue Lakes, Alpine Co.. July and Aug- ust (Blaisdell). These females are distinguished among those with creamy- white markings by the white ventral scopa, face entirely black and scutellum and axillae having prominent light markings. It is, however, a source of perplexity that I do not find a cor- responding series of males. The possible males have the scutel- lum and axillae entirely black, or at least with very small light spots, and certainly do not represent any form of A. emargi- natum. These females appear to agree with A. emarginatum except for the black tibicC. Only field observations will deter- mine the actual facts. Vol. XIV] COCKERELL—ANTHIDIINE BEES 355 18. Anthidium maculosum Cresson Females from Yosemite Valley, Calif., June 21 (Van Dyke) ; Sisson, Calif., July 24 (Van Duzee), and Mokelumne Hill, Calif. (Blaisdell). Males from Anacapa Island, May 15 (Van Duzee), Huntington Lake, 7000 ft., July 27 (Van Duzee), Mill Creek Canon, San Bernardino Co., Sept. 21 (Van Duzee), all in California, and Hereford, Arizona, July 12 (J. R. Slevin). Cresson in 1878 described A. luaculosum from fe- males collected in Utah and California; in 1916 he designated Utah as the type locality. In 1904 I described A. lupincllum from the male collected in New Mexico, and in 1923 recorded this species from the Gulf of California region. The six Cali- fornia and Arizona males before me are considerably larger than the type of lupincllum, but otherwise identical. I have now no doubt that lupinellum is the male of maculosum, and the species is to be known by the latter name. 19. Anthidium palliventre Cresson This was based on a female collected in California by Hy. Edwards, characterized by the entirely black face, scutellum and axillae, hair of the head and thorax above yellowish, ven- tral scopa entirely pale. The same collector obtained A. cali- forniciim, described from males. After a good deal of per- plexity I am now compelled to conclude that they are sexes of one species, which takes the prior name A. palliventre. However, the color of the scopa varies from white to nearly all black, only the sides remaining white. I am convinced that this is not a specific character. Such variation has been re- corded before, as in A. astragali Swenk. The females assigned to palliventre come from San Francisco, Calif., April (Van Dyke) and May (Kusche); Colma, Calif., August 15 (Kusche), and San Miguel Island, Calif., May 20 (Van Du- zee). The last mentioned is unusually large with corners of sixth abdominal segment prominent. These all differ from the female of A. temiiHorce Ckll. in having abdominal bands more or less interrupted in middle and the divisions claviform mesad. The male (A. calif ornicuni Cress.) comes from Colma, Calif., 356 CALIFORNIA ACADEMY OF SCIENCES' [Proc. 4th Ser. Aug. 15 (J. A. Kusche), and San Francisco, May 10, 21 and 30 (Kusche), and April 20 (Van Dyke). The dorsal hair of head and thorax is ferruginous, whereas in males from Los An- geles (Davidson) it is white, as I recorded in 1904. 20. Anthidium plumarium Cockerell, new species Male: Aspect of A. calif oniicum, including the red dorsal pubescence. At first I thought it a mere variety or race, but it is surely a distinct species by the following characters: Lateral apical lobes of abdomen stout but pointed (broadly rounded in calif oniicum) ; mandibles broader; mouth parts ferruginous ; upper edge of clypeus black with two pointed extensions downward ; sixth abdominal segment with only two small yellow spots. Evidently derived from A. calif ornicum (palUventre). Type: Male, No. 1736, Mus. Calif. Acad. Sci., collected by Dr. E. C. Van Dyke, June 5, 1924, at Meadow Valley, Plumas Co., California. 21. Anthidium tenuiflorae Cockerell This Rocky Mountain species proves to extend into the Paci- fic coast region. The females are very like those of A. palUven- tre, but may be separated by the abdominal bands being very narrowly interrupted, the divisions not claviform but strap- shaped. The eyes are also darker. The ventral scopa is usually mainly or almost wholly black, but it varies to all light in Huntington Lake specimens. Females are from Huntington Lake, Calif., 7000 ft., July 4 (Van Duzee) ; Steen Mountains, Oregon, June 25 (Van Dyke), and Longmire, Rainier Na- tional Park, Wash., July 27 (Van Dyke). The last mentioned has the bands unusually slender. Males are from Longmire (same date as females) and Crater Lake, Oregon, 7000 ft., July 17 (Van Dyke). 22. Anthidium banningense Cockerell The following references are to males; the basitarsi are cream colored in front and the anterior and middle tibiae have a s[X)t.

Utah: Logan, July 14 (Van Duzee); lateral apical spines of abdomen broader; sixth and seventh segments entirely black. Apparently not a race, as one of the Meadow Valley si>ecimens is the same. Readily known from male A. emarginatum by the long nar- now lateral apical lobes of abdomen and the tegtuiient of scutel- lum wholly black. 23. Anthidium angulatum Cockerell, new species Male: Similar to E. emarghiatnm Say, but rather less robust; abdominal bands conspicuously paler (creamy white), and reduced to fine lines at the broad emarginations ; hair of thorax above white ; scutellum entirely black or with a pair of minute pale marks. Apical lobes of abdomen angulate as in A. emarginatum. Differs from A. emarginatum atripcs Cresson by the broad band on fifth abdominal segment and pair of large comma-like marks on sixth, small pale marks on bases of tibiae, and creamy white basitarsi. The clypeus may have or lack two small black spots. Perhaps to be regarded as a Californian race of A. emarginatuvi. Type: Male, No. 1737, Mus, Calif. Acad. Sci., collected by E. P. Van Duzee, July 7, 1919, at Huntington Lake, Fresno Co., California, at 7000 ft. Paratype, one male, taken by Dr. E. C. Van Dyke, July 11, 1915, at Fallen Leaf Lake, California. 24. Anthidium brachyurum Cockerell, new species Male : Length about 10 mm. ; black, the head and thorax with white hair, very fainty tinged with yellowish dorsally; flagellum obscurely red- dish beneath except basally ; light markings cream-color, the light parts being entire clypeus, lateral marks, truncate at about level of antennae, mandibles except apically (red just before the black apex), small spots above eyes, tegulae in front and small mark behind, small marks at bases of tibiae, elongate mark near end of front tibiae, subquadrate mark at apex of mid tibiae, the basitarsi, large lateral and small dorsal marks on first abdominal segment, second segment similar but with larger dorsal marks, segments 3 to 5 with narrowly interrupted bands, deeply emar- ginate laterally, sixth with very large hook-like marks ; seventh segment 358 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. entirely black with very broad low lateral lobes narrowly separated from the central spine ; tubercles, mesothorax, axillse and scutellum entirely black ; eyes pea-green ; mesothorax extremely densely punctured ; wings dusky; hair on inner side of hind tibiae white. With the type I associate two other specimens differing in some respects : Salt Lake City, Utah, June 27, 1922 (Van Duzee) ; hair of head and thorax above abundant, light fulvous; apical lobes separated from spine by a deeper, rounded, emargination, but hardly half breadth of lobe; sixth seginent with two large pyriform marks. Redding, California, July 7, 1918 (Van Duzee) ; subapical marks on anterior tibije very minute; marks on sixth seg- ment smaller; emargination between lobes and spine rather shallow and not abrupt. I think these are all one species, however. It is known from the related species by the broad low apical lobes of abdomen. Its nearest relative appears to he A. montivagum Cresson. Type: Male, No. 1738, Mus. Calif. Acad. Sci., collected by Mrs. H. E. Ricksecker, in July, 1920, at Cisco, California. 25. Anthidium hamatum.

Differs from A. pecosense wilsoni (Ckll.) by the entirely black mesothorax and much shorter spines at sides of sixth segment (in wilsoni they are long- and dark) ; they are how- ever, closely allied. In wilsoni the tegulae have the whole outer margin yellow. Type: Male, No. 1741, Mus. Calif. Acad. Sci., collected by E. P. Van Duzee, July 26, 1918, at Sisson, California. 28.

Anthidium lucidum Cockerell, new species Male; Length about 10 mm.; black, with lemon-yellow markings; hair of head and thorax white. Resembles A. puncticaudttm, but smaller and more slender, with apical lobes of abdomen narrower, obtusely pointed, abdomen more shining, upper part of clypeus with two large hook-shaped black marks, lateral face marks going very little above level of top of clypeus, tubercles tipped with yellow, scutellum with two very small yellow marks, bands on tibiae reduced and broken, first abdominal segment with only lateral spots, and these not very large, second segment with band like that on third, sixth with two hook-shaped marks, seventh all black. This is closer to A. titttsi Qcll., differing by the entirely black scape, clypeal marks much deeper yellow, face marks lemon-yellow, ab- dominal bands, etc. The California form which I have regarded as A. titiisi has the scape black and the abdominal bands strongly yellow. It is between the two and perhaps better associated wdth A. lucidum, but additional observations are desirable. A. angiilatum Ckll. is also related but clearly distinct. Type: Male, No. 1743, Mus.

Males, all from California, as follows: Mokelumne Hill, June and Sept.

The Kings River one lacks the yellow spot on mesopleura. As in the allied D. provancheri the face markings are cream colored in the male, lemon-yellow in the female. The female clypeus has the middle broadly or narrowly black, there is a well developed triangular supraclypeal mark and a bar-like yellow mark below the anterior ocellus. In the male the clypeus is all light, the supraclypeal mark is a mere dot, and the mark before the ocellus is absent or represented by a very small line. The abdominal bands are broadly and deeply emarginate at sides posteriorly in the male but with much smaller emargina- tions or entire in the females. It seems difficult to associate as sexes insects so different, but I believe they certainly belong together. Ashmead (1896) described what he called the female, but part of the description refers to the male, part to the female. In 1904 I reported what I took for D. consimilc, but it was really D. provancheri Titus. In 1916 (Pomona Jl. Ent. and Zool., VIII, p. 63) I gave characters to separate the males of the two species. 39. Dianthidium parvum (Cresson) Females: Logan, Utah, July 18 (Van Duzee).

Dianthidium parvum baculifrons Cockerell, new race Female : Face marks light yellow including lower lateral corners of clypeus, so that the black part of the clypeus rapidly narrows apically; a short yellow bar below middle ocellus; entire margin of scutellum broadly, and axillae, yellow; lateral emargination of abdominal segments short, deep and rounded; scopa shining white (distinctly yellow in D. parvum). This is intermediate between D. parvum and D. provancheri, differing from the latter by the paler face markings, with more black on clypeus; hind tibiae black with a large pale yellow patch at base above, and sixth abdominal segment entirely black. It should perhaps be considered a form of D. provan- cheri, or a distinct species. Titus described only the male of D. provancheri. Type: Female, No. 1746, Mus. Calif. Acad. Sci., collected by E. P. Van Duzee, June 5, 1917, at Soboba Springs, Riverside Co., California. Callanthidium Cockerell, new genus Outer recurrent nervure going beyond end of second cubital cell ; no pulvillae on feet. On account of these characters I thought to refer these bees to the neotropical genus Hypan- thidiiirn, in which certain African and Indian species have al- ready been placed. These large North American forms are, however, strongly divergent, not only by their size, but espe- cially in the armature at the apex of the abdomen. The sixth segment is deeply emarginate in the middle in the female and the apex of the male abdomen shows a median spine and large lateral lobes. There is some affinity with Dianthidium, to which genus I wrongly referred the type species in 1914. Type, C. illustre (Anthidium illustre Cresson). 41. Callanthidium illustre (Cresson) California: Yosemite Valley, June 21 (Van Dyke) ; Soboba Springs, Riverside Co., June 2 (Van Duzee) ; Poway, San Diego Co., May 24 (Blaisdell) ; Meadow Valley, Plumas Co., 356 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th See. 3500-4000 ft., June 21 (Van Dyke) ; Bear Valley, San Ber- nardino Co., July 13 (F.

In 1904 I described a supposed species, Anthidium serranum, from Rock Creek, California. It was recognized as valid by Swenk in 1914, but I now consider it only a variation of Cal- lanthidium illustre, to be called C. illustre serranum. It is not even certain that it is a valid race. 42. Callanthidium conspicuum (Cresson) California: Fallen Leaf Lake, July 17 (Van Dyke). Ore- gon: Fremont National Forest, Klamath Co., 5000 ft., June 18 (Van Dyke). I have an apparently authentic female of Dianthidium balli Titus, labelled "Blydenburgh." On comparison with C. con- spicuum it proves to be identical. 43. Callanthidium formosum (Cresson) Oregon: Crater Lake, 7000 ft., July 17 (Van Dyke). Described (under Anthidium) from Colorado, There are no pulvillae and the species is near to C. conspicuum, but easily separated by the end of the male abdomen, the emargination of which is broader than Cresson's figure shows. I had sug- gested that this might be the male of Dianthidium cressonii D. T., but that has pulvillae, much darker wings, and the first recurrent nervure ending far from base of second cubital cell (practically at basal corner in C. formosum). 44. Callanthidium formosum pratense Cockerell, new species Male: Yellow stripes on head above nearly meeting in middle line; yellow marks on mesothorax in front larger ; tegulse with very large yel- low patch ; scutellum with a pair of yellow stripes ; first abdominal seg-' ment with the yellow marks produced in hook-like form ; band on third Vol. XIV] COCKERELL—ANTHIDIINE BEES 2)67 segment narrowly continuous in middle, and not notched behind ; seventh segment yellow right across, and the median spine only about half as long as the distance between it and the lateral lobes.

PROCEEDINGS OF THE CALIFORNIA ACADEMY OF SCIENCES Fourth Series Vol. XIV, No. 16, pp. 369-390 September 18, 1925 XVI STUDIES IN THE TENEBRIONID^, NO. 2 (COLEOPTERA) BY FRANK E. BLAISDELL, Sr. The first number of the present studies appeared in the En- tomological News of January, 1918 (Vol. XXIX, p. 7.). The new species and subspecies of Eleodes described below have accumulated since the publication of my Monographic Revi- sion of the Eleodiini (Bull. 63, U. S. Nat. Mus.) in 1909. The material studied since then has cleared up the doubtful status of several of the phases given at that time. Mr. Leng in a foot-note (p. 227) in the Catalogue of the Coleoptera of America North of Mexico, remarks that I have more recently elevated several such names to higher rank, "the original pre- sumption in such cases having been apparently erroneous," In the mass of heterogeneous material upon which I based my monograph, there were numerous instances in which the specimens were too few for a correct and definite understand- ing of the relationships ; as a result, many subspecies and races were not recognized and unwittingly considered as forms, — not wholly from ignorance in many cases, but more truly as acts of conservatism, I having believed it to be more logical and truthful to raise than to lower a grade, whenever more positive data warranted it. September 18, 1925 ^JQ CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. From the standpoint of taxonomy, the solution of the ques- tion of specific relationship is not going to come from the study of dried museum specimens, but must be the result of careful ontogenetic and ecologic studies of large series of specimens collected in the different geographic regions. Such research must be pursued with untiring zeal if we are to arrive ultimately at some conception of the laws governing the divergence of organisms. The raising of certain forms to a definite grade does not invalidate the conception of such intra-specific groups, for even then the specific aggregates will be made up of variants, as no two individuals of any species can be exactly alike as regards size, form, sculpturing and color, no matter how much re- stricted taxonomically. With Dr. E. C. Van Dyke, I prefer to use the term "phase" in a generic sense to include all vari- ants of a species, subspecies or variety. When a species is limited taxonomically the intra-specific, intra-subspecific or intra-varietal variants can be grouped according to size, form, sculpturing or color, each group constituting a form. These are really ecological groups. I expressed these same ideas in my monograph. In 1909 I presented the conception of forms as a means of directing attention to the variation within specific units so as to make them objects of research. I advised that forms should not he given a place in a check-list, for on the very face of the matter they are absolute synonyms according to the author and from the standpoint of taxonomy. We must have laws and rules of guidance, otherwise everything passes into con- fusion, and yet to enforce them rigidly or literally may retard science rather than advance it. The enforcement of laws or the application of rules must be tempered by good judgment, this is absolutely necessary, for no law or rule is strictly ap- plicable in all cases; hence the need of flexibility in the appli- cation of a rule. Certain recent changes in our nomenclature have been founded on paleographic facts much to the con- fusion of other branches of science. A word or two regarding extremists versus the intermediate path. Conservatism, when extreme, retards the progress of science. Most of this is due to the exercise of the personal equation rather than to biological inquiry. A species relegated Vol. XIV] BLAISDELL—THE TENEDRIONIDJE 2>7\ to synonymy is supposed to be defunct for all time and yet some synonymical lists are rich in research material. The other extreme usually overrates biological facts, but the result more than balances the harm done by the stimulus it gives to discussion and research. Why not pursue the more logical and sane path, — bury the personal equation and let intensive re- search dictate the biological data ; the deductions will then be both progressive and scientific. Forms may be said to constitute ecological groups, for the units of a species exhibit individual differences which are very evidently due to environment and not to reactions in the germ plasm. It may be admitted that environmental conditions will affect the germ plasm in the course of centuries. Environ- mental conditions are constantly changing and therefore un- staple : They change from day to day, from month to month, and from year to year ; first warm then cold, dry and then wet, over a whole region or any part of a region, even to small and restricted areas. That is why one season yields notable vari- ations and the next something still dift'erent. A consideration of the principle ecological factors capable of bringing about variations in size, form, sculpturing and color in organisms, includes temperature, humidity, quantity and quality of food, coupled with geographical position. Any one taking cognizance of these facts should eliminate if possi- ble all individual variations (forms) of known or described species, subspecies and varieties before describing any of them as new to science. Let it be kept in mind that the earth is Nature's great experimental laboratory and that it is an in- finite field for research. The limitation of species, subspecies and varieties is quite arbitrary in the present state of our knowledge. A species as at present defined, with its subspecies and varieties constitutes a specific complex. I believe that all subspecies and varieties should be recognized aiid named as they constitute taxonomic subgrades. The main idea in doing this is to make them ob- jects of research. The definition of a species is too well known for me to repeat it, but I would like to make known what I understand by subspecies and variety or race. The usual ency- clopedic definition leads the student in a circle so that he usually knows just as much after his investigation as he did 372 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. when he began. My definitions have been formulated from observations in the field. I assume that I am dealing- with a specific phase worthy of subspecific grade whenever a series of specimens has been col- lected in some particular geographical region apart from the type and, as a whole, presents some notable difference in form, size, sculpturing or color from the type. I assume likewise that a variety (race) is to be recognized when a series of specimens presents some minor but constant difference in size, form, sculpturing or color from the type, and usually inhabits the same geographical region, but in some areas the varietal phase may predominate. A subspecies or va- riety interbreeds with the t)^pe if inhabiting the same geo- graphical region or area. The regions of distribution of type, subspecies and variety may overlap and this accounts in part for the confusion which exists regarding what constitutes a subspecies oi variety. I believe that ontogenetic research must decide the relationships in the Insecta. The student in the field must work out the distributional and seasonal phases. Forms in the sense defined above should be recognized, studied and properly placed in collections, and discussed in current papers and monographs, but not given in a check-list. The following new species, subspecies, and varieties are presented at the present time : 1. Telabis nevadensis Blaisdell, new species Form elongate oblong-oval, a little more than twice as long as wide, moderately convex. Color piceous brown, dark rufous beneath, legs paler; luster dull to somewhat shining. Head a little transverse, sides moderately convergent and feebly arcu- ate before the eyes, the latter somewhat prominent and coarsely faceted; epistoma slightly produced, arcuato-truncate at apex, sides briefly oblique from the shallow emarginations ; front very slightly convex, very feebly and broadly impressed laterally within the sides, moderately and dis- cretely punctate, punctures somewhat coarser, deeper and more or less coalescent on the epistoma ; vertex more or less strigose. Antennae long and slender. Pronotum nearly twice as wide as long; apex moderately emarginate, angles obtuse and blunt ; base feebly bisinuate, marginal bead rather broad and flat in middle third ; basal angles obtuse and distinct ; sides evenly and moderately arcuate, feebly convergent anteriorly, margin rather thin Vol. XI\] BLAISDELL—THE TENEBRIONID^ 373 and narrowly rcflcxed, slightly crcnulale ; disk moderately convex, dis- cretely punctate; punctures smaller in middle third, thence somewhat coarser and more oval, with their margins quite distinct and not coales- cent; sides narrowly impressed but rather more widely so toward the basal angles. Proplcura with a few scattered hairs; rather coarsely, but not densely punctate, punctures shallow ; intervals somewhat prominent longitudinally. Elytra oblong, about a half longer than wide, sides parallel and feebly arcuate, apex broadly rounded, humeri obtuse and not in the least promi- nent, although somewhat exposed; disk moderately convex, finely and subasperately punctate, punctures somewhat confused at base, sides and apex, series quite distinct in the central area. Sterna sparsely and not very coarsely punctate; punctures shallow; mesosternal epimera irnpunctate ; transverse metasternal ante-coxal line well defined and almost entire. Abdomen moderately evenly convex, finely and very sparsely pimctate along the middle, rather more coarsely so laterally; under surface of the body clothed with scattered hairs. Length (types) 6-6.5 mm.; width 2.4-2.8 mm. Holotypc, male, and allotype, female, in my collection. Paratypcs in the collection of Mr. Warren Knaus and in that of the author. Type locality: Las Vegas, Nevada, collected July 31, 192L A series of five specimens. This si^ecies evidently falls into the series with Casey's iitcana and aiiiica, both from Utah. In nevadensis the punc- tuation of the head and pronotum is discrete, not very dense (rather more abundant in the female), shallow and scarcely asperate, not muricate ; the vertex of the head may be more or less longitudinally strigose. According to Casey, uteana is piceous black in color and arnica is pale testaceous, and he makes no mention of the vertex of the head being strigose in either species. 2. Eleodes quadricollis lassenica Blaisdell, new subspecies Form and sculpturing similar to that of quadricollis Esch., but more strongly and densely punctate throughout. Color intense black. Pronotum more arcuately and strongly declivous laterally, and as a result more strongly convex from side to side. Anterior spurs of the protibise more elongate in both sexes. Male : Narrower elongate-oval. Female : Ovate, sides more arcuate ; elytra just noticeably inflated. Sexes otherwise as in quadricollis. 374 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Length (types) 17-18.5 mm.; width 7-8.5 mm. Holotype, female, and allotype, male, in the author's col- lection. Type locality: Martin's Spring, Lassen County, California. Section 14. Tp. 31 N, R. 9 E. Collected by Mr. J. O. Martin, on July 10th. 1922. A single pair. In huHieralis Lee. the pronotal marginal bead is visible throughout the length when viewed vertically from above; in quadricollis and related species the lateral marginal bead is more or less invisible from above. The main diagnostic characters of lassenica, are the denser, stronger sculpturing and less elongate form. 3. Eleodes parowana Blaisdell, new species Form oblong-oval to oblong-ovate, rather strongly convex, a little more than twice as long as wide. Color deep black and feebly shining. Head moderate in size, densely punctate before the eyes ; vertex sparsely punctate ; sides arcuate at the supra-antennal convexities, thence straight and convergent to the frontal angles, the latter obtuse ; epistoma broadly and evenly emarginate ; frontal sutures not evident. Antennse rather stout and moderate in length, tenth joint transversely oval, the three-jointed club very slightly wider than the preceding joints. Pronotum quadrate to slightly transverse, widest at apical third ; apex truncato-emarginate in moderate circular arc ; sides quite strongly arcuate in apical half, thence straight, oblique and moderately convergent to base, marginal bead fine ; apical angles nearly rectangular ; base transverse and the angles obtuse but not in the least rounded ; disk moderately strongly convex, declivous laterally, finely and rather densely punctate, punctures slightly larger laterally, those of the central area being a little more widely separated. Elytra oval, base sinuate lateral to the scutelluni, the latter triangular ; humeri obtuse and rather distinct; sides evenly arcuate, apex moderately narrowly rounded ; disk costate, costje moderately convex, smooth and sparsely punctulate, intervals finely and more abundantly, irregularly punctate; punctures on the apical declivity slightly muricate. Legs mod- erate in length and stoutness, as well as rather densely sculptured. Tarsi moderately stout. Male: More elongate oblong-oval, front of head more convex. Pro- notum subquadrate, widest at middle as viewed from above. Elytral hiten'als alternately costate. Abdomen very slightly oblique to the sterna, strongly impressed at middle of first two segments, inter-coxal process broad. Anterior spurs of the protibiae produced and moderate in stoutness. Vol. XIV] BLAISDELL—THE TENEBRIONWJE 375 Female: Oblong-ovate, broader. Pronotum wider than long, widest in front of the middle. Elytra costate as in the male with the intervening intervals more or less convex, sides with an incipient margin; apical de- clivity arcuate and moderately abrupt. Abdomen rather strongly convex. Anterior protibial spur produced and thickened as in the female of qiiadricollis. Length (types) 15-16.5 mm.; width 6-7.8 mm. Holotypc, female, and allotype, male, in my collection. Para- types in that of Mr. Warren Knaus of McPherson, Kansas. Collected on "the Mammoth," at top of Parowan Mountains, Utah, on July 12-22, 1921, at an elevation of 10,000 feet, by Mr. Knaus, while on the Mininger-Hoover Ex^Dedition. Four specimens studied. The elytral sculpturing of paro- wana is unique in the qiiadricollis section of the subgenus Melaneleodes. Extending backward from the humeri is an angulation indicating the beginning demarcation of the in- flexed sides from the dorsum of the elytra, as observed in tricostata and pediu aides, although the elytra are strongly convex and not depressed as in the latter species. In parozvana the anterior protibial spurs are produced and stout as in qiiadricollis. In the tricostata group the spurs are produced but they are not so stout. This new species is a most interest- ing and surprising addition to the subgenus Melaneleodes. 4. Eleodes parowana mimica Blaisdell, new variety Mimica resembles parowana in most characters, but differs, chiefly in the character of the sculpturing, as follows : Form rather more robust, integuments rather denser. Elytral sculp- turing more strongly developed and like that observed in the oval form of tricostata; alternate intervals strongly convex, surface scabrous from rather fine and quite densely placed muricate punctures ; the intermediate intervals may become feebly subcostate. In parowana the elytral punctures are very fine and quite equal throughout, scarcely at all or very feebly asperate at times. In other words in parozvana the punctuation resembles that observed in typical porcata Casey, except that the punc- tures are equal in size. In mimica the punctuation is like that of tricostata Say. The pronotum and the anterior tibial spurs 376 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. are as in the quadricollis group. In the tricosfata group the pronotum is distinctly transverse. Length (types) 17-16 mm. ; width 6.5-7 mm. Holotype, female, and allotype, male, in my collection. Paratypes in that of Mr. Tanner. Type locality: Bryce Canon, Utah. Collected by Mr. Vasco M. Tanner on July 27th, 1922. 5. Eleodes fuscipilosa Blaisdell, new species Form rather elongate subfusiform-ovate to ovate, slightly depressed above and a little more than twice as long as wide. Color black through- out, luster rather dull. Head rather small, front very feebly convex, impressions obsolete, densely and rather finely punctate, punctures much sparser on the vertex ; epistoma subtruncate at apex, sides quite straight and slightly convergent anteriorly, angles distinct and rather narrowly rounded, supra-antennal convexities feeble. Eyes rather narrow. Antennae moderate in length, gradually and very slightly incrassate in outer joints; joints four to seven longer than wide and obconical, eighth triangular, ninth and tenth slightly transverse, eleventh obovate and rather obliquely truncate at tip. Pronotum subquadrate, relatively small, widest at about the middle, base and apex subequal ; apex quite truncate and the angles very distinct, obtuse and not prominent anteriorly ; sides rather evenly but not strongly arcuate, almost straight posteriorly and moderately convergent to base, marginal bead fine ; base feebly and broadly arcuate, the angles obtuse ; disk rather evenly convex, most strongly so laterally and declivous as usual in the quadricollis group, finely and almost evenly punctate, punc- tures well separated. Elytra suboval, base scarcely wider than the pronotal base, slightly emarginate and adapted to the pronotal base; sides moderately arcuate, convergently so to apex in apical fourth, the apex rather narrowly rounded ; disk more or less depressed, more or less moderately and more abruptly rounded into the deflexed sides, rather abruptly and arcuately declivous posteriorly ; surface quite discretely muricato-granulate, gran- ules small and shining at summit, not well developed in the central sutural area, irregularly placed, but with a suggestion of a serial arrangement when viewed longitudinally from behind; each granule with a short nearly erect and somewhat stiff brownish hair which is scarcely conspic- uous. Epipleura rather narrow and but slightly wider toward base. Sterna finely and rather densely muricato-punctate. Abdomen finely and rather closely punctate ; segments rather strongly convex antero-pos- teriorly. Legs moderate in length and stoutness. Vol. XIV] BLAISDELL—THE TENEBRIONIDX y?7 Male: Narrower, subfusiform-ovate. Pronotum about as wide as long; antennae slightly stouter; elytral disk less depressed. Abdomen slightly oblique to the sterna; first and second segments flattened in middle third, with a median longitudinal impression. Tarsi rather stout ; first protarsal joint not noticeably thickened at apex beneath. Anterior protibial spur distinctly lengthened and stouter than the posterior. Female : Broader and ovate. Pronotum slightly wider than long. An- tennae rather less stout. Elytral disk noticeably flattened. Abdomen hori- zontal and moderately strongly convex. Tarsi rather less stout. Anterior protibial spur very distinctly enlarged. Length (types) 14-16 mm.; width 5-8 mm. Holotype, female, and allotype, male, in my collection, both collected at Parowan, Utah, at an elevation of 6000 ft., on July 24-25, 1921, by Mr. Warren Knaus while on the Minin- ger-Hoover Expedition. FuscipUosa belongs to the quadricollis section of the genus on account of the enlarged anterior protibial spurs. It differs from all others of the group in the relatively small head and pronotum and brownish pubescence of the elytra. It should follow coloradensis in the list of species. 6. Eleodes reducta Blaisdell, new species Form oblong-ovate, about two and a third times longer than wide and moderately strongly convex. Color deep black, luster somewhat shining. Head moderate in size, front very slightly convex, impressions feebly indicated, most marked within the supra-antennal convexities ; densely and irregularly punctate, with small impunctate areas, punctures rather small, becoming still smaller and sparser on the vertex ; sides rather arcu- ately prominent over the antennal base, thence becoming sinuate, straight and obliquely convergent to the narrowly rounded epistomal angles ; apex of the epistoma broadly and feebly emarginate. Eyes narrow. Antennae moderate in stoutness and length, attaining the pronotal base; joints four to eight slightly longer than wide, ninth about as long as wide and sub- globular, tenth slightly wider than long, eleventh short obovate and trun- cate at tip. Pronotum subquadrate, widest at about the middle ; apex truncate in circular arc, apical angles obtuse and distinct ; sides broadly and moder- ately arcuate, becoming straight or slightly sinuate to base, marginal bead very fine ; base broadly but not strongly arcuate, sometimes feebly sinuate 378 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. at middle ; basal angles obtuse ; disk evenly convex, more strongly so lat- erally, marginal bead more or less visible from above, punctures small and distinct, more or less regularly placed and not crowded. Elytra oval, less than twice as long as wide ; base feebly emarginate and adapted to the pronotal base, slightly wider than the latter, humeri obtuse and not prominent ; sides broadly and moderately arcuate, con- verging to apex in apical third, the latter rather narrowly rounded ; disk moderately convex on the dorsum, more strongly so laterally but not rounding broadly into the moderately inflexed sides, punctures feebly muricate, rather evenly distributed, although slightly denser at the sides and apex where they become more strongly muricate, irregularly placed, with unimpressed strise evident ; rather abruotly and arcuately declivous posteriorly. Sterna more or less finely muricato-punctate ; abdomen more sparsely punctate. Legs of moderate length and stoutness. Male: Narrower, pronotum about as wide as long. Abdomen slightly oblique to the sterna, first two segments flattened in the central area, with a slight median longitudinal impression. Protarsal plantar grooves open, first joint not noticeably thickened at apex beneath. Female : Broader, pronotum a little wider than long. Abdomen hori- zontal and rather strongly convex. Protarsal plantar grooves closed on the first joint, the latter prominent at apex beneath and set with small black spinules. Anterior protibial spurs enlarged and thickened. Length (types) 15-17.5 mm.; width 6-7.5 mm. Holotype, female, and allotype, male, in my collection. A fe- male paratype is in the collection of Mr. Vasco M. Tanner. Dixie Normal School, St. George, Utah. Collected near Cove Fort on the Beaver County line, Utah, June 20th, 1922, by Mr. Tanner. Reducta is related to humeralis, but at first sight resembles obsoleta forma punctata, and is readily separated from it by the enlarged anterior protarsal spurs of the female. The form is less robust than m humeralis and the sculpturing is less dense and more muricate; in humeralis the sculpturing is dense, more granular and very minutely muricate, the lateral pro- ;iotal margin is distinctly visible from above as a result of the disk being less arcuately declivous at the sides. Coloradensis is more robust and less elongate. The elytra in fuscipilosa are clothed with short brownish hairs, while in concinna the ely- tral sculpturing consists of small discrete shining granules. Vol. XIV] BLAISDELL—THE TENEBRIONIDJE 379 7. Eleodes mazatzalensis Blaisdell, new species Form elongate-ovate, somewhat depressed, a little more than twice as long as wide. Color deep black and shining. Head moderate in size, about as long as wide, almost flat, feebly im- pressed laterally ; punctures moderate in size, not crowded, slightly smaller and somewhat sparser on the vertex. Antennae moderate in length, slightly compressed distally, scarcely at all incrassate; third joint very little longer than the fourth and fifth taken together; fourth joint just the least longer than the fifth; fifth, sixth, seventh and eighth subequal in length, last two very little stouter and feebly triangular ; ninth and tenth oval, scarcely longer than wide ; eleventh oblong-oval, a little longer than wide and rather broadly rounded at apex. Pronotum about two-sevenths wider than long, widest slightly in ad- vance of the middle ; sides rather broadly arcuate in anterior three- fourths, thence moderately convergent and feebly sinuate to base, mar- ginal bead fine ; apex truncate ; apical angles obtuse and distinct ; base very feebly arcuate and about equal to the apex ; basal angles obtuse, almost distinct ; disk moderately and evenly convex from side to side, feebly so antero-posteriorly, quite strongly declivous laterally behind the middle, noticeably so at the apical angles, surface finely and sparsely punctulate, slightly alutaceous. Elytra oval, feebly wider posteriorly, sides broadly arcuate, apex mod- erately broadly rounded ; disk with distinct lines of punctures, the latter moderate in coarseness, rather closely but irregularly spaced, intervals with an irregular line of sparsely placed punctules ; surface rather de- pressed in the central area, almost vertically declivous posteriorly. Humeri small and acute. Sterna quite densely punctured. Abdomen finely punctato-rugulose ; horizontal in both sexes. Legs moderate in length ; the posterior notice- ably longer in relative proportion than the anterior. Male : Somewhat narrower. Abdomen feebly flattened along the middle of the first three segments. Inner spur of the anterior tibiae a little stouter than the outer; plantar grooves open on all the tarsi, except at the tip of the first joint of the anterior tarsi, where it is closed by a transverse row of coarse blackish spinules. Female : Slightly broader. Antennae relatively a little longer ; abdomen evenly but not strongly convex. Male, length 14 mm., width 6 mm.; female, length 18 mm., width 7 mm. Holotype, male, and allotype, female, in the collection of the Entomological Department of the Agricultnral College of Cor- nell University, Ithaca, New York. Para type, female, in the anthor's collection. Types bear the label : Lot 445, Sub. 3. 380 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Type locality: Mazatzal Mountains, Arizona, collected Sept. 1-3. The anterior tarsi are imperfect on both types, only the first and second joints being present. The sexes are similar in form, and suggestive of the females of dissimilis Blais. In the latter the plantar grooves of the anterior tarsi are open in both sexes, and the elytral punctuation is finer. The tarsal characters and tibial spurs correlate mazataalensis with the carbouaria section of the subgenus Melaneleodes. A second female in the Agricultural College collection is more finely sculptured. 8. Eleodes coloradensis Blaisdell, new species In my Monographic Revision of the Eleodiini this species was recorded as a form of humeralis Lee. (Forma tubcrcitlo- inuricata). The collecting of recent years has contributed much toward the elucidation of the relationship between cer- tain phases that were of dubious status at the time the above monograph was written. I made no mistake, however, in con- sidering the above species as related to humeralis Lee. I gave simply the relationship as I interpreted it from the meager material that was before me at that time. I will now present a modified description considering it a species : Form robust and less elongate than humeralis Lee. Pronotum more arcuately declivous laterally, with the margins more or less invisible from above. Elytra more coarsely and strongly sculptured, subtuberculately muricate with the punctures much sparser than in humeralis. Length (types) 16-16 mm.; width 5.5-7 mm. Holotype, female, and allotype, male, in my collection. Both types were collected in Colorado, the male by C. V. Riley. In coloradensis the elytral granules are larger and more like tubercles. It is separated from humeralis by the more robust form, sparser and coarser sculpturing of the elytra, as well as the more abruptly declivous sides of the pronotal disk. It is more robust than fuscipilosa, with a relatively larger head and pronotum and the absence of distinct hairs on the elytra. In rileyi Casey the elytral sculpturing is sparser and not asperate. Vol. XIV] BLAISDELL—THE TENEBRIONID/E 3gl 9. Eleodes concinna Blaisdell, new species This species was considered as humcralis forma graiinlato- muricata in my Monograph (Bull. 63, U. S. Nat. Mus., 1909). Many specimens collected in Nevada, Lassen and Plumas counties in California have been studied and compared during the last decade. My present conviction is that it should have full specific rank. Concinna may be defined as follows : Form elongate, oblong-ovate to ovate, less robust and more sparsely- sculptured than humeralis Lee. Elytra moderately convex on the dorsum, sides more or less broadly rounded ; disk less densely sculptured with small muricate granules which are shining at their summit. Length (types) 15.5-16 mm.; width 5.8-7 mm. Holotype, male, and allotype, female, in my collection. The male was collected in Lassen County, California, and the ac- companying female was taken at Carson, Nevada. Distribution: Nevada (Verdi, April — Blaisdell; Carson City, July; Reno, — Wickham; Utah, — Riley). California (Lassen County; Plumas County, April 25th, — Essig.) The specimens from Lassen County, California, "have the elytra discretely granulate; each granule under low power of magnification is polished and shining, under high power the granules are minutely pointed at their summit." This form of sculpturing constitutes the typical phase. 10. Eleodes wenzeli Blaisdell, new species Form oblong-oval with elytral disk flattened. Color deep black, luster somewhat alutaceous, surface smooth, almost glabrous. Head relatively small, front very slightly convex, impressions obsolete, punctures fine, discrete, slightly coarser on the epistoma ; sides feebly arcuate over the antennal fossse, thence feebly sinuate and straight, con- verging to the narrowly rounded epistomal angles, apex of the epistoma feebly and broadly emarginate. Antennae moderate in length, joints four to seven slightly longer than wide, subequal, seventh slightly shorter, ter- minal joint not thickened, as long as wide, subglobular and slightly compressed. Pronotum subquadrate, as wide as the elytra, widest slightly in ad- vance of the middle; apex slightly emarginate in feeble circular arc; apical angles subacute and slightly prominent anteriorly ; sides broadly and moderately arcuate in anterior two-thirds, thence less so, straight 0O7 CALIFORNIA ACADEMY OF SCIENCES [Puoc. 4th Ser. and very moderately convergent to the basal angles, marginal bead dis- tinct and moderately fine ; base very feebly arcuate ; basal angles obtuse ; disk moderately and evenly convex, finely and not closely punctate, basal impressions obsolete. Elytra oblong, narrowing posteriorly, about twice as long as wide ; base feebly emarginate and adapted to the pronotal base, humeri slightly ex- posed, small and obtuse ; sides broadly arcuate, subparallel, gradually converging to apex in apical third, apex rather narrowly rounded ; disk flattened on the dorsum, moderately convex, rather abruptly rounding into the moderately inflexed sides, arcuately and rather obliquely declivous posteriorly, finely, not closely and quite evenly punctate, punctures not subasperate, obsoletely striate. Epipleura very gradually widening toward base and comparatively narrow. Sterna and abdomen shining, feebly and not densely sculptured. Legs moderately long, femora rather stout ; tarsi somewhat slender. Male: Form oblong, parallel; elytra flattened on the dorsum. Abdomen oblique, to the sterna and impressed in the middle third of the first two segments. Length 19 mm. ; width 8 mm. Holotype, male, in the author's collection, taken in the Chisos Mountains of Texas, on July 24, by Mr. H. A. Wenzel, after whom the species is named. Wenaeli belongs to the pc din aides group of the subgenus Melaneleodes. It can readily be recognized by its smooth, finely sculptured integuments and alutaceous luster. In spccu- HcoUis the pronotal disk is polished and shining, the elytra rather strongly sculptured. Neomexicaua is duller in luster and the elytra are rather densely but not coarsely subasper- ately sculptured, while pedinoides is larger, more shining and the elytra striate; asperata Lee. has the elytra more strongly and very distinctly muricate at the sides and on the apex. 11. Eleodes speculicollis Blaisdell, new species Similar in form to neomexicaua Blais. Surface more shin- ing, the pronotal disk polished. Pronotum evenly and moderately convex, basal impressions feeble or obsolete ; base broadly and not strongly emarginate at middle ; disk with several fortuitous impressions, not present in the males. Elytra moderately feebly convex on the dorsum, laterally rather less broadly rounded than in ncomexicana; surface obsoletely striate, inter- vals indicated as faint subglabrous lines, punctures confused, rather dense Vol. XIV] BLAISDELL—THE TENEBRIONW.^ ^^:^ and somewhat fine, not at all granulato-muricate, except slightly so on the apex.

Spcculicollis is readily separated from neomexicana by its shining integuments and polished pronotal disk and smoother elytral sculpturing. Three males and one female have been studied. It is the author's belief that neomexicana Blais. should be considered a distinct species and not a race of pedi- noides Lee. 12. Eleodes obscura glabriuscula Blaisdell, new subspecies Similar to dispcrsa Lee. Color deep black, surface smooth and shining. Elytral sculpturing consisting of stria; of coarser punctures; intervals with a single series of similar punctures that are more widely spaced with the surface slightly rugose laterally and on the apex, where the punctures become more or less asperate and the sculpturing confused ; punctures simple on the dorsum. Sterna and abdomen polished. Male narrower as in dispersa. Female broader and rather less elongate. Length (types) 30-28 mm.; width 10-11 mm. Holotype, female. No. 1814, Mus. Calif. Acad. Sci., collected by C. D. Duncan, July 12, 1921, at Alpine, Texas. Allotype, male, collected by C. D. Duncan, July 9, 1921, on Livermore Peak, Davis Mountains, Texas. In the form deleta Lee. the elytral sulci are obsolete, except at the sides behind the middle, where some faint traces of them are seen ; the punctures are submuricate and arranged in strise, distinct on the dorsum, but confused at the sides ; betw^een the rows are distinct punctures as in obscura Say; posteriorly abruptly declivous and furnished with rows of tubercles, alter- September 18, 1925 384 CALIFORNIA ACADEMY OF SCIES^CES [Proc. 4th Ser. nately large and small. In arata Lee. the elytral sulci are deeper than in siilcipennis Mann, and therefore quite different from glahriuscula. 13. Eleodes hispilabris connexa Lee. This subspecies was unknown to me in nature when my monograph was written. A couple of years ago a pair of spe- cimens collected at Albuquerque, New Mexico, came into my possession. Both sexes are narrower than in hispilabris Say, and the integuments are denser. Le Conte's description very correctly defines the subspecific characteristics : "Elongate, black and bright, thorax moderately punctulate with sides rounded, anterior angles acute and slightly prominent; basal angles obtuse. Elytra elongate oval, intervals subconvex and more or less rugose, subacute posteriorly." Type locality, Prairie Paso, Texas. It is a distinct subspecies. 14. Eleodes hispilabris nupta Say This variety of hispilabris Say was first described from spe- cimens taken at Laredo to Ringhold Barracks, Texas. It is less elongate, more robust and the elytra are more or less in- flated, sometimes markedly so. Many specimens are more or less broadly rufous along the elytral suture. Nnpta has been heretofore quite rare, not many specimens having been col- lected in recent years. I have recently received the loan of twenty- four specimens from the entomological collection of the University of Kansas, through the kindness of Prof. R. H. Beamer ; also seven spe- cimens from Mr. Warren Knaus of McPherson, Kansas. Both series were collected on the sand hills about Medora, Kansas. Those from the University collection were taken on April 13th, 1925, with the exception of one specimen which was collected in SheiTnan County, Kansas, at an elevation of 3600 feet by Mr. F. X. Williams. The latter specimen is quite identical with one in my own collection secured at Fort Supply, Okla- homa. Those loaned to me by Mr. Knaus were in part also collected in April, on the 25th, the others on September 17th, 1916. Vol. XI\] BLAISDELL—THE tenebrionid^ 385 A pair was first submitted to me for identification and I thought that they represented a new race of hispilabris Say, until I saw the entire series. Niipta Say has a wider distribu- tion than was at first beheved. The body form of the Kansas series is more hke that of the females of the carhonarux, omissa and quadricollis sections of the subgenus Melaneleodes Blais. The small prothorax, shorter and broader, and the more or less inflated elytra gives quite a different facies from that of the typical hispilabris Say. The specimens collected in September are more decidedly red along the suture than those collected in April. This may be due to a somewhat immature condition or to retardation and alteration in the chemical constitution of the pigment. The darker individuals appear to have firmer integuments. 15. Eleodes dentipes montana Blaisdell, new variety Form and color of dentipes. Pronotum very finely but not densely punctate. Elytra with unimpressed stria; of rather coarse and closely placed punctures, with single interstitial series of slightly smaller and rather more widely spaced punctures; series not confused laterally or apically. Length (types) 24-23 mm.; width 8.1-9.2 mm. Holotype, female, and allotype, male, in my collection. Col- lected in the Santa Cruz Mountains, near Mt. Hermon, Santa Cruz County, California, on July 20, 1922. In dentipes Esch. the pronotal punctuation is a little coarser and that of the elytra finer and confused laterally and apically. In confinis Blais. the punctuation is still finer and the sides of the pronotum are straight posteriorly and not in the least sinu- ate before the basal angles. In perpunctata Blais. the form is more elongate, the punctuation variable and the sides of the pronotal disk are impressed, dull and granulate within the bead. Dentipes and montana have the pronotal disk glabrous and transversely convex from bead to bead. Tidarensis is more alutaceous, the legs and antennae are slender and the 3g^ CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. elytra are oval, the humeri being obsolete. In the race marincu Blais, the elytral punctures are diffuse and of equal size throughout and the form is rather more robust. 16. Eleodes dentipes tularensis Blaisdell, new subspecies Form elongate, subfusiform oval. Color black, luster rather dull. Head about a third wider than long, feebly convex and with very shal- low impressions within the antennal convexities ; finely and sparsely sub- asperately punctate, punctures rather dense laterally and on the epistoma. Antennae rather long, moderately slender, last three or four joints slightly wider. Pronotum about a seventh wider than long, base quite equal to the apex, the latter feebly emarginate in circular arc, finely or obsoletely beaded; base feebly arcuate and finely beaded ; sides broadly and rather moder- ately arcuate, briefly sinuate before the basal angles which are distinct but feeble; apical angles small, dentiform and more or less everted; disk rather evenly and moderately convex, finely and sparsely punctate, scarcely denser laterally, not impressed along the margin but narrowly opaque with granulate punctures, marginal bead fine, rather thin and very feebly reflexed. Propleura sparsely, rather finely, subasperately punctate with scattered rugulse. Elytra fusiform-oval to oval. Base equal to the pronotal base, trun- cate to feebly bisinuate ; humeri very small or absent ; sides quite evenly arcuate, rather narrowly rounded at apex ; disk moderately arcuate, more strongly rounded laterally, rather obliquely declivous apically ; evenly and sparsely punctate, punctures equal in size, arranged serially in the central area, and closely placed in the series, interstitial punctures rather widely spaced, all becoming confused laterally and on the apex where they are minutely muricate, with the prickles discernible. Parapleura finely and more thickly punctate. Abdomen sparsely punc- tate, punctures finely subasperate. Legs rather long and noticeably slender. Male : Narrower and fusiform oval in form. Abdomen nearly on a plane with the sterna, very moderately convex and just noticeably flat- tened along the middle. Female : Broader, elytra more oval. Abdomen a little more convex. Legs less slender. Male, length 15.5 mm., width 8 mm.; female, length 14 mm., width 9 mm. Type locality: Northfork, Fresno County, California. Col- lected by Mr. Henry Dietrich on March 4, 1920. \'0L. XIV] BLAISDELL—THE TENEBRIONWJE 337 Holotype, female, and allotype, male in my collection; para- fvpcs in Mr. Dietrich's and my own collection. A female para- type has been placed in the collection of the California Academy of Sciences by Mr. Dietrich. A series of twelve specimens have been studied. The salient characteristics of titlarensis are the absence of humeri and the unusually slender legs. The anterior femora have a small triangular tooth at about the outer fourth. Con- finis Blais. is found in the foothills on the west slope of the Sierras and coast range foothills as well, and is a robust race with the pronotal sides without basal sinuations. Perpunctafa Blais. is a larger and more elongate race, legs long and stout, sides of the pronotal disk noticeably impressed along the lat- eral margins ; the latter character being entirely absent in fularnisis. Marines Blais., a stouter more compact race found in Marin County, California, has the elytral punctuation dis- tinct, the punctures diffuse and of equal strength throughout. 17. Eleodes parvicollis alticola Blaisdell, new variety In form similar to trita, but less opaque and more finely punctured. Oblong-ovate, a little more than twice as long as wide. Head finely punctate, the punctures slightly denser at the periphery. Pronotum about a fifth wider than long; finely and not very closely punctate, punctures slightly larger and somewhat granulate laterally in the marginal area, where the disk is very feebly impressed ; apex, sides, base and angles as in producta. Propleura rather sparsely granulato- punctate, more or less rugulose on the coxal convexities. Elytra less elongate than in producta and planata, about a third longer than wide; base truncate, wider than the pronotal base; sides moderately arcuate, apex obtusely and somewhat narrowly rounded ; disk somewhat flattened, but moderately convex, less so in basal fourth, obliquely and arcuately declivous posteriorly; surface not eroded, moderately densely punctate, punctures slightly muricato-granulate, laterally and apically. Prosternum rather densely punctate, elsewhere the punctures are more widely separated and not coarse. Abdomen densely and not very finely granulato-punctate on the first and second segments, less so on the third, fourth and fifth finely and sparsely punctate. Legs moderately stout. Sexual differences as in trita. 3g8 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Length (types) 14-14.5 mm.; width 6.5-7 mm. Types, male and female, in my collection. Type locality: Piute Mountain, Kern County, California; collected May 29th, 1913. Many specimens have been iden- tified. Alticola is more shining and less coarsely punctate than trita Blais. although similar in form. Plaiiata Esch. is more elongate and there is greater difference in body form between the sexes, besides it inhabits a different geographical region — the oak groves of the great valleys, while trita and alticola are found at higher altitudes in the mountains. Constricta Lee. is more strongly and coarsely punctate, with the elytra more depressed on the disk and the basal constriction of the pro- notum is stronger and more abrupt, with the sides perfectly straight and parallel before the basal angles; in alticola the sinuations are more gradually formed and the sides not par- allel. 18. Eleodes manni dilaticollis Blaisdell, new variety Form oblong-oval, less than twice as long as wide, more robust and less elongate than manni Blais. Color deep black. Head more transverse and the antennae rather shorter than in nwnni. Pronotum distinctly more transverse than in the latter species and more strongly and a little more coarsely, closely punctate. Elytra more broadly oval, humeri more or less distinct, disk more noticeably muricately punc- tate laterally and about the apex. Otherwise as in manni. Length (types) 13-15.5 mm.; width 5.6-7.6 mm. Holotype, female, and allotype, male, and paratypes in my collection. Mr. M. C. Lane of Ritzville, Washington, also pos- sesses paratypes and collected the types at Sprague, Washing- ton, on May 15, and June 19, 1921; other specimens were secured at Lake McElroy, Paha, Washington, on May 24th. In the types the humeri are distinct. A considerable series has been studied and the differential characters have been found constant. Vol. XIV] BLAISDELL—THE TENEBRIOMID^ 389 In parvicollis Esch. and its races the pronotal punctures are smaller and more distinctly separated. In manni var. variolosa Blais, the elytra are more coarsely and subrugosely sculp- tured, a character resembling that observed in cordata Esch. ; the pronotum is less transverse and subequal in the sexes. In dilaticollis the pronotum is much more transverse in the female. In horni Blais. and its race monticola Blais. the sculpturing is finer, legs more slender and the surface luster more opaque. As a rule manni and its race dilaticollis have the pronotal sides less abruptly sinuate at base than is found in parvicollis and its races. These characters are maintained in larger series. Sierra Blais. is more alutaceous, elytra more parallel with the humeri more or less distinct. 19. Eleodes nigrina difformis Blaisdell, new subspecies Form and size variable, more robust than typical nigrtna Lee, mimic- ing omissa Lee. ; the males less elongate. Color black, luster more or less moderately shining. Sculpturing as in nigrina. Comparative stoutness of appendages variable. Male : Less elongate and broader, differing but little from the female in form. Female: Broader on the average than the female of ttigrina; pronotum quadrate to a fourth wider than long. Length (types) 20-20.5 mm.; width 8-9 mm. Variations in size; largest female, length 23 mm., width 9.5 mm.; smallest female, length 15 mm., width 6 mm. Holotype, female, and allotype, male, in my collection. Para- types in the collection of Mr. M. C. Lane. Ritzville. Wash- ington, and in my own. The types were collected at Lind, Washington, on April 10, 1920. I am indebted to Mr. Lane for a generous series showing the remarkable variation in body fonn and size. Most of these specimens were taken in the vicinity of Ritzville, in September and October, 1921. Large series of nigrina Lee. show an adherence to a uni- form body form, and the individuals are more elongate and duller in luster, while the race perlonga Blais. is more elongate, polished and shining. Schivarzi Blais. has a differently formed 390 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. pronotiim and is on the whole more robust as regards the dorso-ventral thickness of the body. Nevadensis Blais. is more slender, very dull and alutaceous in surface luster. Neobaphion Blaisdell, new genus This genus is proposed to receive Eleodes planipenms Lee. The genital characters are embaphionoid and the body form that of an Eleodes. It is therefore to be placed between Eleodes Esch. and Embaphion Say. in our lists. Since the Monograph on the Eleodiini (Bull. 63, U. S. Nat. Mus.) was written, at least three new species have been studied, unfortunately as uniques, but all referable to the genus as given above. For further data consult the above cited monograph. PROCEEDINGS OF THE CALIFORNIA ACADEMY OF SCIENCES Fourth Series Vol. XIV, No. 17, pp. 391-425 September 24, 1925 XVII NEW HEMIPTERA FROM WESTERN NORTH AMERICA BY EDWARD P. VAN DUZEE Curator, Department of Entomology The present paper contains the descriptions of 41 new spe- cies and subspecies of western Hemiptera. In great part these represent species that have accumulated through the field work of the curator of the department of entomology, in Cali- fornia and neighboring states. Their study has been inciden- tal to the determination of the Hemiptera in the collection of the Academy, during the past five years, and are now pub- lished so the names can be used in work now in progress on our interesting western insect fauna. 1. Vanduzeeina calif ornica Van Duzee, new species Larger and less hairy than balli with a longer and more parallel head ; testaceous brown, closely fuscopunctate, apex of scutellum with an oblong pale spot. Length 6-7 mm. Head as wide between the eyes as long, but slightly narrowed apically, sides nearly rectilinear ; cheeks shorter than tylus, their surface depressed next the prominent median portion of the tylus, their apex roundedly truncate ; bucculae high and subacutely angled as in balli. Sides of pro- notum distinctly sinuate anteriorly, the anterior angles prominent ; in balli nearly rectilinear or very feebly arcuated ; transverse median impres- September 24, 1925 392 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. sion feeble. Upper surface less convex transversely than in halli. Punc- tures on venter hardly as close as on dorsum, the median line smooth. Vestiture short, gray. Rostrum attaining apex of second ventral segment. Color soiled testaceous brown, closely fuscopunctate, the head, pro- notum and connexivum more or less tinged with rufous ; lower surface of head and sides of pectus nearly black; apex of scutellum with an oblong pale spot, rounded anteriorly and widened on hind margin, spar- ingly fuscopunctate and often outlined with fuscous ; dorsum sometimes with a slender median white line more or less complete ; pronotum usually with a pale point either side before the black annular callosities ; expanded anterior angles pale ; connexivum annulate at base of each segment. Antennae fuscous, the incisures pale. Legs fuscous, the knees and tarsi pale. Described from four male and three female specimens taken at Cisco, Calif., July, 1911, by Dr. Charles von Geldern and one taken by Dr. E. C. Van Dyke in Yosemite Valley Park, June 26, 1921. The larger size, short sparse vestiture, sinuated pronotal margins, more parallel head and pale apical spot on scutellum will distinguish this species. As in allied scutellerids the male is more uniform in coloration with the pale markings more or less obsolete. Type: Male, No. 1748, and allotype, female, No. 1749, Mus. Calif. Acad. Sci., collected in July, 1911, by Dr. Chas. von Geldern, at Cisco, Calif. 2. Vanduzeeina borealis Van Duzee, new species Differs from californica in being larger, in having the cheeks more convex with their margins more acute and over- hanging, and the disk of the pronotum more feebly, trans- versely impressed. The specimens at hand, two females, show a more distinct percurrent pale median carina above and the apical pale spot on the scutellum is scarcely indicated and is more triangular in form. Anterior pronotal angles more rounded, the humeral angles bounded by deeper depressions. Length 7.5-8 mm. Described from two females, one taken by Mr. Wheeler at Emerald Lake, B. C, August 15, 1915. the other from Golden, Vol. XIV] VAN DUZEE—NEW HEMIPTERA 393 B. C. This should perhaps be considered as a subspecies of calif ornica but it has the aspect of a distinct species.

Margus repletus Van Duzee, new species Size and aspect of ohscurator Fabr., but with legs and an- tennae more robust, surface more strongly dotted with fuscous, tylus more rounded and less prominent and the spines of the antenniferous tubercles more acute. Length 8 mm. Head a little longer than broad across the eyes ; ocelli more distant than in ohscurator, obviously nearer the eye than to the median line; tylus scarcely exceeding the cheeks, rounded, not compressed and prominent as in ohscurator. Antennas stout ; segment I as long as head to hind margin of eye, one-fourth as wide as long, strongly narrowed on basal third; segments II and III subequal to I, IV a little shorter and thicker than III ; tooth on antenniferous tubercle terete, exceeding the tubercle by width of segment II. Pronotum narrower than in ohscurator, the expanded sides recurved, anterior angles broader and more obtuse ; median line sub- carinate behind the transverse depression ; nervures of membrane stout, strongly anastomosing as in inconspicuns; whole upper surface strongly punctured, each puncture with a short golden hair. Rostrum attaining anterior line of intermediate coxae. Male genital segment shorter, vertical, broadly sinuate at apex. Color testaceous gray, tinged with yellowish on head and connexivum ; maculated and strongly punctured with fuscous, including the legs and antennse, the connexivum and tibiae alternated with darker areas ; beneath pale, dotted with rufous or fuscous, these punctures forming a row on hind edge of each ventral segment ; vertex showing a pale median mark at base and two raised spots either side of base of tylus ; tip of antennae rufescent. Described from one male taken in Palm Cafion, San Jacinto Mts., Calif., at 2000 feet elevation, June 12, 1909, by Mr. Fordyce Grinnell. In Stal's key this runs to nigropunctatus but differs in several particulars. Type: Male, No. 1751, Mus. Calif. Acad. Sci., collected by Fordyce Grinnell June 12, 1909, in Palm Canon, San Jacinto Mts., California. 394 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. 4.

Described from two male and five female examples taken by me from under stones at Nogales, Arizona, April 3, 1921. In structural characters this species is allied to femoralis but it is very distinct otherwise. Type: Male, No. 1752, and allotype, female. No. 1753, Mus. Calif. Acad. Sci., collected by E. P. Van Duzee, April 3, 1921, at Nogales, Arizona. 5. Lygidea essigi Van Duzee, new species Closely related to ohscura Renter, a little broader, darker colored, head fuller and antennae thicker. Length 6 mm. Male: Vertex strongly convex, highly polished, basal carina slender, with a deep depression before it, median line very feebly impressed ; clypeus less prominent than in obscura, its basal incisure shallow ; eyes Vol. XIV] VAN DUZEE—NEW HEMIPTERA 395 smaller than in obscura.

Color black; cheeks, except at base, a very obscure median line on vertex, a broader one on posterior lobe of pronotum, collum and cuneus, except at apex, pale yellowish ; vestiture pale, rather conspicuous on scutellum and elytra; membrane deep smoky and a pale annulus at apex of areole ; legs and beneath pale yellow with a broad black vitta either side, covering most of the genital segment; apex of femora and tips of tibi.e fuscous, the tarsi mostly black; antennae black; rostrum mostly pale. Described from the unique type. It is impossible to identify this with Lygidea morio Rent., a species still unknown to me in nature. Type: Male, No. 1754, Mtis. Calif. Acad. Sci., collected by Prof. E. O. Essig, May 19, 1922, at Los Altos, Santa Clara Co., California. 6. Camptobrochis slevini Van Duzee, new species Size and aspect of rnUvcntris Knight but belonging to his group II having the scutellum punctate and the arolia without a deep cleft. Apparently allied to atriventris Knight but dif- fering in many respects; deep black, cuneus red, head and scutellum opaque, rugose-punctate. Length 5 mm. Male: Head one-half as wide as base of pronotum; closely rastrate- punctate and opaque, with sparse white hairs. Segment I of antennae much exceeding the head, II stout, two and a half times as long as I; III and IV wanting in type. Pronotum with coarse shallow punctures ; hind margin broadly emarginate, the humeri scarcely retreating; sides ecarinate. Scutellum flattish, opaque, closely rugose-punctate including the basal lobe.

Rostrum attaining apex of hind coxse; mesosternum and pleura? in part opaque. Sinistral notch of male genital segment rounded, the sinistral clasper broad, flattened and rugose, its apex becoming terete and curved under around apex of segment. Color black, moderately polished ; the head, collum and scutellum opaque or scarcely shining; base of vertex, tip of scutellum, middle of tibiae and most of tarsi testaceous; thickened inner margin of corium beyond tip of clavus and the cuneus red, the latter with basal and apical angles blackish; margin of acetabulae and osteolar region vvhitish. De- scribed from the unique type. In size, form and coloring this species recalls Pocciloscytus venaticns. It is somewhat aberrant in this genus but does not better fit into any other. Type: Male, No. 1755, Mus. Calif. Acad. Sci., collected by Mr. L. S. Slevin, September 18, 1920, at Carmel, California. It affords me pleasure to dedicate this species to its discoverer. 7. Strongylocoris unifcrmis Van Duzee, new species Allied to rohiistns Uhler, but with the legs and antennas entirely black and wnth different male genitalia. Length 4 mm. Vertex convex and highly polished ; clypeus a little shorter than in rohustus; antennae a little shorter and more robust. Dextral male clasper forming a semicircle vertically but without lateral curvature, within widened in a bluntly rounded lobe at basal third, and at distal third armed with a very acute tooth, the long slender apical member acute, becoming castaneous at tip. Sinistral clasper small, slender, its acute apex sharply incurved over the sedeagus. Color deep polished black, apical half of the antennae becoming fuscous, membrane deep fuliginous toward its apex with a paler mark at apex of cuneus. Antennae and sides of pronotum and elytra with a few brown hairs. Described from two males and eleven females taken on sage brush at Heber, Utah, July 5, 1922. The almost uniform black color and long, acutely produced dextral male clasper will distinguish this species. Type: Male, No. 1756, and allotype, female, No. 1757, taken by E. P. Van Duzee, July 5, 1922, at Heber, Utah. Vol. XIV] VAN DUZEE—NEW HEMIPTERA 397 8. Largidea pudica Van Duzee, new species A little larger than fnarginata; polished luteous-brown, slightly tinged with red, the cuneus red ; vertex, mark on pro- notum and the antennae blackish. Length 4.5 mm. Male : Head larger with the eyes more prominent than in marginata. Antennae about as in marginata; segment I a little longer than the vertex when viewed from above ; II as long as head and pronotum together ; III and IV slender, together nearly one-half of II. Pronotum a half wider than long, more convex above than in marginata, the sides less strongly carinate and nearly rectilinear ; hind edge more broadly exca- vated ; surface less closely punctured. Scutellum broader and more convex with the sides steep, the depressed tip acute ; punctures subobsolete. Elytral punctures larger, more distant and becoming subobsolete. Rostrum scarcely surpassing middle of mesosternum. Surface sparsely clothed with cinerous appressed hairs which become denser on callosities and vertex. Color a lurid luteous-brown ; apex of tylus and cheeks, a narrow median cloud or two crescentic vittae on face, region of callosities and basal lobe of scutellum black; antennae reddish fuscous, the base of segment I clearer red ; hind edge of pronotum pallid ; cuneus red ; membrane faintly smoky, the veins fuscous ; legs and abdomen in part reddish, the tarsi, rostrum and mesosternum blackish. Described from two males, one taken by me at Colestin, Oregon, the other taken by Mr. W. M. Giffard at Tallac, Cali- fornia, August 22, 1916. The polished surface and luteous- brown color gives this species quite a different aspect from marginata. Type: Male, No. 1758, Mus. Cahf. Acad. Sci., taken by E. P. Van Duzee, August 1, 1918, at Colestin, Oregon. Paratype in collection of the author. 9. Orthotylus plucheae Van Duzee, new species Allied to hamatus, smaller with different male genitalia, base of tylus with a dark spot ; pale greenish, tinged with yel- low, membrane faintly smoky, segment I of antennae dusky in male. Length 4.5-5 mm. General characters essentially those of hamatus, the pronotum more convex and more narrowed before, with its sides distinctly concavely arcuated. Sinistral male clasper terete, reaching but about half way to 398 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. apex of genital segment, exceeded by the brown chitinized spine-like ventral member. Dextral clasper ligulate, curved over and considerably passing the middle of the segment, its truncate apex with a minute sharp ventral tooth, its dorsal edge notched at basal third and armed there with a short parallel tooth. In hamatiis the sinistral clasper is much larger and more slender and pointed, and the dorsal notch of the dextral clasper is larger with a longer tooth. Rostrum attaining hind edge of meso- sternum. Color pale yellowish green, minutely white-pubescent; antennae of male dusky with the inner face of segment I pale ; membrane faintly but obvi- ously smoky, with pale veins; tip of tarsi and of the rostrum black. Described from 6 males and 3 females taken on Pluchea sericea at Potholes, Imperial Co., California, April 13, 1923. This is very close to hamatits but the smaller size and much less developed male genitalia would seem to indicate specific distinction. Type: Male, No. 1759, Mus. Calif. Acad. Sci., collected by E.

Orthotylus cupressi Van Dtizee, new species Dusky green with fulvous scutellum; surface clothed with rather long- black hairs; outer half of membrane deeply infus- cated, cut by a white spot at apex of areole. Length 5 mm. Male : Head broad, convex above, somewhat obscuring the basal carina ; clypeus but moderately prominent. Rostrum attaining apex of hind coxae. Pronotum short, twice wider than long, regularly arcuate before. Scutel- lum, large, rather convex. Elytra nearly parallel, the costa but feebly arcuated. Sinistral clasper developed transversely in an open crescent, its dorsal member about twice longer than its basal thickness, acute at apox ; ventral member broadly obliquely truncate at apex, its upper angle forming a short curved hook, its lower curved and very acute, nearly attaining the base of the dextral clasper ; the latter, also, subcrescentic, its ventral member ligulate with its twisted truncated apex at median line of the segment, its dorsal member forming a short erect acute tooth. Color a dull, almost an olive, green, paler toward the costa, the tylus and front of pronotum tinged with yellow ; cuneus paler with a whitish cloud at base ; membrane infuscated, its outer half, including the areoles, darker with a pale mark at apex of the areole; tergum black; beneath paler, the mesosternum tinged with fulvous-brown ; legs and antennae yellowish green, clothed with short black hairs ; apical two segments of antennae infuscated, the tarsi becoming black at apex. Described from one male and three female examples taken by me on Sargeant's Cypress growing on "Cypress Ridge" at Fairfax, Marin Co., Calif., April 30, 1922, and May 11, 1919. This species is very distinct from any heretofore described. Its dark green color, fulvous scutellum, heavy black vestiture and infuscated membrane will distinguish it, while the male claspers are unlike those of any other species known to me. It has slightly the aspect of an Ilnocora but does not pertain to that genus. Type: Male, No. 1761, Mus. Calif. Acad. Sci., collected by E. P.

The large eyes, elongate narrower form and long hind legs would ally this species with Argyrocoris but it is certainly a Parthenicus. The larger size, darker color, black scale-like vestiture, dotted hind femora and red dotting on elytra and veins of membrane will distinguish this species from haccharidis Knight.

III and IV slightly infuscated; coxae and rostrum infuscated; vestiture of short golden scales and longer pale hairs on head, sides of pronotum and base of costa. Described from 30 examples representing both sexes. This species may be distinguished from rubromaculosus Knight (1925) by the larger size, deep red scutellum sides of Vol. XIV] VAN DU ZEE— NEW HEMIPTERA 403 pronotum and hind femora, and the pale fuscous color on inner field of corium.

Cyrtolobus pictus Van Duzee, new species Near inermis Emmons, agreeing with that species in the form of the dorsal crest, in the unicolorous pale green female and the strongly maculated male ; differing in the shorter pro- notum and in the markings of the male. Length 4-5 mm. Allied to van but smaller, dorsal crest lower with the anterior sinus scaicely indicated in the male; in the female with the crest more uni- formly arcuate with an anterior sinus ; apex of pronotum even shorter than in vati, not attaining tip of fourth apical vein; face not as flat as in van; smooth, polished, uneven, obscurely punctured toward apex of cheeks, incisures of clypeus deep, its apex rounded. Elytra hyaline, in male with veins heavy and fuscous, the apex with a small smoky cloud, about half of which lies on the apex of the areoles. Female without such cloud, the veins pale, concolorous ; surface sparsely clothed with short erect hairs. Color a uniform pale green in female ; male a clear greenish yellow on face pronotum, legs and margins of pleural pieces; face with a median vitta, a cloud either side and the clypeal sutures black ; pronotum with a mark above each eye, the apex and a broad triangular vitta behind the middle, black, including a dorsal yellow mark; anterior to this vitta is a broad vague oblique maculate area either side meeting above the humeri. These markings on the male leave the anterior portion of the pronotum, a ravher wide, oblique, median vitta, a dorsal spot more or less completely connecting with this vitta, and a wide transverse subapical band, yellow. In van this dark color is more extended with the included pale dorsal spot larger. Edges of abdominal segments and genital pieces mostly yellow. Femora black in the male, with their apices broadly yellow, the tibiae minutely dotted. Descriljed from 8 male and 12 female examples beaten from oaks growing along the canon of the south fork of the Provo River at Vivian Park, Utah. This species is really nearest to inennis Say and like that species might almost as properly be placed in subgenus y\tymna. The male may be distinguished Vol. XIV] VAM DUZEE—NEW HEMIPTERA 409 by the different and more extended yellow markings of the pronotum. In acutus, which was taken in company with this species, the female shows more maculation on the pronotum and the pale markings of the male are narrower and do not include the front of the pronotum. It is also larger and has the pronotum more pointed at apex. The females of pictiis differs but little from those of inermis and the female specimen from Ogden, Utah, recorded by me in my Studies on the Mem- bracidce (Bui. Buf. Soc. Nat.

Color pale testaceous, tinged with fulvous on vertex and scutellum ; vertex with a pair of small spots behind apex, another pair either side near base ; sometimes a point within the ocelli and a broken transverse band just behind the ocelli brown, the broad incised line black; front with obscure arcs, outer angles of lorae with black points ; pronotum mot- tled with brown, anteriorly pale with three large spots either side ; scutellum with two discal dots, a small lateral spot either side and a transverse band before the apex brown, the curved incised line black; elytra whitish, venation brown, becoming fuscous on costa and apex; commissural vein and tips of claval veins white, with a fuscous spot ante- rior to each white vein and one at apex indicated ; disk of a few of the areoles with vermiculate inscriptions ; beneath pale, slightly varied with brown ; anterior and intermediate femora bilineate ; tibiae with strong black dots ; pale spines of pygofers set in black points, sides of oviduct black. Male : Proportionately shorter than the female ; valve short, broadly angled ; plates acutely triangular, but little shorter than wide at base, sides straight. Described from 8 females, 7 of which were beaten from cha- parral and juniper bushes at Mill Creek Canon, San Bernar- dino Mountains. The other I took at Pine Hills, Cuyamaca Mountains, California, October 19, 1913. Three individuals 412 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. have the vertex distinctly shorter but I fail tO' detect any spe- cific differences. Also two males: Colestin, Jackson Co., Ore- gon, August 1, 1918, and Mt. Tamalpais, Marin Co., Cali- fornia, June 23, 1918. Of Aligia inscripta, in addition to the type, I have seen ex- amples from San Diego Co., Pasadena, Mt. Wilson, Stanford University, Mt. Tamalpais, Alameda, Cazadero, Bryson, and Cayton, California. These have the last ventral segment of the female about as in calif ornica but differ in their stouter form and banded elytra. Type: Female, No. 1783, Mus. Calif. Acad. Sci., collected by E. P. Van Duzee, September 22, 1923, in Mill Creek Canon, San Bernardino Mts., Calif.; allotype, male. No. 1784, Mus. Calif. Acad. Sci., collected by E. P.

Last ventral segment of female nearly truncate, the apex slightly produced and notched. Valve of male scarcely angled; plates somewhat longer than broad at base, becoming narrow at apex ; sides ooncavely arcuated, apices diverging, brown with pale basal area, the tips and bristles white. In this species the sides of the front are a little more arcuated and the clypeus is wider than in californica. Color testaceous tinged with fulvous on vertex, scutellum and anterior margin of pronotum; markings of vertex as in californica with the three pairs of points larger, one pair at apex and one next each eye; pronotum with a whitish longitudinal median line ; markings of scutellum as in californica but darker; elytra whitish hyaline with heavy fuscous vena- tion ; a transverse dusky band at middle and another before apex some- times indicated ; commissure with three white areas followed by fuscous marks against the tips of the nervures ; apex of membrane more or less clouded with dark; beneath pale varied with fuscous; anterior femora biannulate with fuscous before, the intermediate with a subapical annulus; face with distinct arcs, its median line and disk of cheeks and lorae pale. Vol. XIV] VAN DU ZEE— NEW HEMIPTERA 41 3 Described from one male and four females taken in Mill Creek Canon, San Bernardino Mts., 3800 ft. elevation. The sharper vertex, more truncate female segment and banded femora will distinguish this species from inscripta and cali- fornica. The markings are stronger than in californica and usually the transverse bands are indicated. I take pleasure in naming this species for our dipterist, Dr. F. R. Cole, formerly of Redlands, California, whose guest I was, and near whose summer cottage I took the species. Type: Male, No. 1785, and allotype, female, No. 1786, Mus. Calif. Acad. Sci., collected by E. P. Van Duzee, September 22, 1923, in Mill Creek Cafion, California. 27. Aligia modesta occidentalis Van Duzee, new subspecies Differs from the eastern form of the species in being more slender in all parts, in being more strongly colored, in having the vertex very feebly angled and the last ventral segment of the female slightly produced and notched at the middle. Eleven specimens, all females, are in the Academy collection. They were taken in California as follows : Mt. Diablo, July 14, 1916; Niles Canon, July 15, 1916; Cloverdale, August 3, 1916; Cayton, July 17, 1918; and Sonoma Valley, August 1916 (W. M. Giffard) all taken on oaks. Also taken by Mr. Giffard in Placer Co., Calif., August 19, 1916. What I be- lieve to be the male of this form I took at Laurel Dell, Lake Co., Calif., August 3, 1916, and Mr. Gift'ard took a second ex- ample in Placer Co., August 19, 1916.

Tamalpais, June 23, 1918, all in California. The broad flat horizontal vertex, transverse costal veinlets and peculiar genital charac- ters will distinguish this very distinct species. Type: Male, No. 1790, and allotype, female, No. 1791, Mus. Calif. Acad. Sci., collected by E. P. Van Duzee, July 15, 1918, at Cayton, Shasta Co., California. 30. Platymetopius pexatus Van Duzee, new species Related to trilincatus but darker with apex of vertex five- lineate with white; the colors darker, apical white spot on elytra elongated, and different male genitalia. Length 5 mm. Head greatly produced, two and a half times as long as wide between the eyes ; sides straight or slightly concave in female, the narrow tip rounded : face concave in profile ; front transversely strongly convex be- tween the eyes, four times as long as wide between the antennae ; clypeus strongly widened at apex.

Described from three females and a male taken by Mr. W. M. Giffard in Placer Co., Calif., August 20, 1916, at 3000 ft. ; a female taken by me at Descanso, San Diego Co., October 18, 1913, and a female from Mill Creek Caiion, San Bernar- dino Mts., Calif., taken September 22, 1923. With the latter I took three females I believe to be trilineatus Ball beaten from yerba santa. They differ from Ball's description only in being more fulvous and in having the lateral lines of the vertex more distinct. Type: Female, No. 1792, Mus. Calif. Acad. Sci., taken by E. P. Van Duzee, September 22, 1923, in Mill Creek Canon, San Bernardino Mts., California. 31. Deltocephalus discessus Van Duzee, new species Closely allied to siguatifrons; proportionately broader and shorter; vertex longer and flatter; valve of male shorter and broadly rounded ; plates narrower ; pygofers longer, surpass- ing the plates by about the median length of the plates. Ulti- mate ventral segment of female shorter, truncate, its outer angles a little longer and roundedly prominent; inner angles rounding to a shallow, narrow, median notch, the fundus of this notch touching an obscure rounded pale lobe, somewhat as in signatifrons; pygofers broader and proportionately shorter than in the related species. Colors a little darker than in typical signatifrons, with more black on the legs and venter ; markings of the legs and vertex substantially the same. Length 2.75 mm. Described from two females and seven males taken by me at Pine Valley, San Diego Co., California, at 4000 feet eleva- tion. This possibly should be considered as a mere race of signatifrons but it seems to me best to give it specific rank as typical signatifrons has been taken at Keen Camp in the San Jacinto Mts., but a little farther north, and at Blitzen River, Oregon.

Head wider than pronotum, convex in both diameters, the anterior edge broadly rounded to front as in Euscelis ; apex produced in somewhat less than a right angle ; pronotum slightly longer than vertex, its curve ante- riorly occupying two-thirds its length ; elytra longer than abdomen, ner- vures distinct ; face typical of genus, the clypeus moderately constricted, apex rounded, scarcely equalling the cheeks. Ultimate ventral segment of female rather long, bilobed, the outer angles rounded, median line incised almost to base and overlapping as in nigriventer. Male genitalia about as in nigriventer ; valve short, feebly angled ; plates large, transversely con- vex, sides feebly sinuate, becoming oblique to the rounded reflexed apex ; bristles long, pale. Color cinereous-brown, tinged with yellow on head and scutellum; vertex with a round black spot within and behind each ocellus ; apex sometimes with a pair of faint spots; incised line scarcely darker; anterior margin of pronotum paler ; elytra subopaque ; nervures white, mostly edged with fuscous, the transverse veins more conspicuously white ; face pale, the sutures, about six arcs on front and apical spot on clypeus fuscous ; sub- antennal cavities black; legs mostly pale, the hind tibiae black in female, edges and spines pale ; pectus and abdomen black, sides of male valve narrowly pale. Described from four male and five female examples taken by me at Forks, Clallam Co., Wash., July 4, 1920. This species has the genital characters of nigriventer almost exactly but it is in no way related to compactus, the form of the head and color characters separating it widely from that species. Two brachypterous specimens are paler and have the elytra a little shorter than the abdomen. Deltocephalus contrarasi Van D. from Sonora is larger with a shorter vertex and thickened elytra with very pale veins. It has, however, the satiie convex rounded vertex and is certainly related.

Introduction When I assumed the duties of Curator of the Department of Paleontology in 1919, I found in the Department two large collections of fossil mollusks from Coyote Mountain, Imperial County, California. These had been borrowed for study and report by former Curator, Roy E. Dickerson, and he had done a very considerable amount of work in the identification of the species. . Up to the time of his departure, he was unable to complete the work to his satisfaction, and in 1920, he turned the matter over to me either to finish or return the col- lections to their owners. After due consideration, the advice of Dr. J. P. Smith and Dr. B. L. Clark was taken and the work of identification was completed as nearly as possible and the collections were returned. Publication has been withheld until this time because it was found that the fauna needed for critical comparison was to be had only in the Gulf of California. Until the Academy sent its expedition there in 1921, no collection of consequence was available in any western museum for consultation. That year, through the untiring industry of Dr. Fred Baker, a very large number of the known species of that province was brought back. Also through his efforts the larger forms have been identified and it has been possible to compare the Coyote Mountain fossils with them. This procedure has prevented a very considerable number of inaccuracies which would have been inevitable had the re- port been published in 1921. The most fertile source of error would have been due to making comparison of this relatively poorly preserved material with living and fossil species from east American and West Indian points. Unquestionably, the Coyote Mountain fauna is closely related to that of the Atlantic, but so is the fauna of the Gulf of California. In no great number of cases does this similarity amount to exact identity of species. Without a good Gulf of California collec- tion for comparison, grave errors would have been un- avoidable. The tropical fauna of the Gulf of California is so vastly different from any known from the California coast that with only the latter and eastern collections available, the natural Vol. XIV] HANNA— COYOTE MOUNTAIN FOSSILS 429 conclusion students would reach would be to associate the Coyote Mountain forms with those of the Atlantic of similar tropical facies. Even with the Gulf of California collection for comparison, this report could hardly have been completed without the hearty cooperation of many paleontologists. Particularly must appreciation be acknowledged to Dr. Fred Baker; Dr. J. P. Smith; Dr. B. L. Clark; Dr. Roy E. Dickerson; Mrs. Kate Stephens; Mr. Chas. H. Sternberg; Dr. W. H. Dall; and Mr. W. C. Mansfield. Location Coyote Mountain, sometimes called Carrizo Mountain, is located in the western part of the Colorado Desert, Imperial County, California. It is close to the great granite range which extends from Mount San Jacinto on the north to Mount San Pedro Martir in Lower California. The base of the mountain is about three miles north of Coyote Wells, a watering station on the highway from San Diego to El Centro and Yuma. The United States-Mexican boundary is about four miles south of Coyote Wells. The crest of the mountain is a ridge about five miles long extending almost east and west. The surrounding country is excessively barren desert and most of the usual erosion- features comm.on to such surroundings are found. Thus there are broad gravel washes, steep box cafions and many perpen- dicular escarpments. North of Coyote Mountain about ten miles there is another and larger mountain mass, likewise an intrusion through Ter- tiary sediments, now known as Fish Creek Mountain. Be- tween it and Coyote Mountain is the flood plain of Carrizo Creek. This is a very ancient waterway ; in the granitic moun- tains which it traverses it has cut a great gorge, celebrated for its scenic features. Coyote Mountain is now easily reached since it is only three miles from a paved highway. Light automobiles are usually driven almost any place on the desert floor and by following the wider washes it is possible to drive into several of tlie main cafions. Alverson Caiion can thus be reached. 430 CALIFORNIA ACADEMY OF SCIENCES (Proc. 4th Ser. Previous Work The original discovery of the Coyote Mountain upHft was made by W. P. Blake, geologist with the Pacific Railroad Sur- vey. The party with which he traveled camped on Carrizo Creek where this stream flows out of its caiion and is lost in the sands of the Colorado Desert. Here some fossils were found and collected.^ These were subsequently described by Conrad^ as Ostrea heermanni, Anomia subcostata and Pecten deserti, all new species and Ostrea vespertina, previously de- scribed from San Diego. ^ With only these four species, Conrad thought the age of the deposit from which they came was probably Miocene. I do not find any other publication based upon original in- vestigations until the report of Charles R. Orcutt was issued in 1890. (See bibliography for references.) He traveled extensively in the Colorado Desert at an early date, and, it appears, made large collections of fossils from the marine sedi- ments in the Coyote Mountain district. He mentioned par- ticularly corals and oysters. Much of his data was reprinted in 1901. H, W. Fairbanks next collected in the region about 1892 and some of the corals he secured were sent to Dr. T. W. Vaughan who described them in 1900. There were two species and one subspecies of these. Dr. Stephen Bowers made another collection of corals in 1901 and published a short paper on his observations. This collection was likewise studied by Dr. Vaughan, who pub- lished some notes on it in Science in 1904. This latter collection was so interesting that Dr. Vaughan arranged to have Dr. Bowers and Mr. W. C. Mendenhall visit the locality and a veiy much more extensive collection was made. A brief list of some of the MoUusca contained in the collection was published in 1906 by Dr. Ralph Arnold. He also included a preliminary list of the corals and described two new species of Pecten from the locality. As a result of • See Blake, Pac. R. R.

Vol. XIV] HANNA— COYOTE MOUNTAIN FOSSILS 431 Mr. MendenliaH's visit, iie published in 1910 the most exten- sive account we have of the geology of the district. One of the sea urchins collected in 1904 was appropriately described the same year by Charles E. Weaver as Clypeaster bowersi. Dr. John C. Merriam of the University of California recog- nized the importance of this locality from a paleontological standpoint and had two large collections made there about 1911-1913. One of these was by Messrs. Kew and Buwalda; the other by Kew and English. As a result of these visits, the most extensive collections thus far taken were assembled. In 1914 Dr. Kew published a paper on the echinoids of the region in which several new species were described. He also included a geologic sketch map and cross section of Coyote Mountain. He also published a list of the Mollusca which had been identified. Only ten of the names were given un- qualifiedly and none of these were gastropods ; all except four had been described from these deposits. This paper was followed in 1916 by one by J. O. Nomland on Cretaceous and Tertiary corals of California and Oregon in which one species from Coyote Mountain was described. In 1917 Dr. T. Wayland Vaughan published an extensive account of the corals collected in 1904 by Messrs. Mendenhall and Bowers. He made extensive comparisons with other faunas and gave a fairly complete resume of all previous work in the region. (It should be noted that the explanations be- neath the two figures on Plate 93, Prof. Ppr. 98, No. 5, U. S. Geol. Sur. are reversed.) Dr. R. E. Dickerson read a short paper before a meeting of the Geological Society of America in 1918 (published only in abstract form) in which previous views on relationships of the Coyote Mountain deposits are given. This was followed in the manuscript by a list of the Mollusca he had identified from the collections. Many collections have been made in the region from time to time, the most important of which I have knowledge being the following: 1. The Blake collection which Conrad studied. 2. The Orcutt collections of 1888 and 1890, studied and reported upon by him. 432 CALIFORNIA ACADEMY OF SCIENCES [PROc. 4th Ser. 3. The Fairbanks collection which went to the University of California and the corals of which were studied by Vaughan. 4. The Bowers collection of 1901, the corals of which were sent to Vaughan while the mollusks eventually came to the California Academy of Sciences. 5. The Mendenhall and Bowers collection of 1904 which went to the U. S. Greological Survey and the corals of which were studied by Vaughan. 6. The Kew and English collection of 1912 which went to the University of California. 7. The Kew and Buwalda collection of 1913 which went to the University of California. The echinoids of the last two collections were studied by Kew. 8. The Stephens and Sternberg collection of 1920 which went to the San Diego Society of Natural History. 9. The California Academy of Sciences collection of 1921 made by the writer. 10. Stanford University collection made at various times and by various collectors. 11. A private collection made at various times by Sternberg and distributed to several institutions. Geology of the District During my visits to Coyote Mountain, I examined many of the caiions minutely, but my purpose was chiefly to search for fossils. Therefore, I am not in a position to add much to the two excellent accounts of structural conditions which have been published.* The most important parts of these papers were quoted by Vaughan (U. S. Geol. Surv. Prof. Ppr. 98, pt. 5, 1917, pp. 355-360). In general, these observers agreed that Coyote Mountain was an island of granitic and metamor- phic rocks, of possibly Carboniferous age at the time of de- position of the Tertiary sediments. This deposition was accompanied in its early stages by some volcanism of minor character. One of the most evident features as the mountain is approached, is the manner in which all strata dip away from ♦Mendenhall, Journ. Geol. Vol. 18, 1910, pp. 336-355. Kew, Univ. Calif. Publ. Geol. Vol. 8, 1914, pp. 39-60. Vol. XIV] HASNA— COYOTE MOUNTAIN FOSSILS 433 the center in every direction. Erosion has cut away many of the soft clay layers and left hard sandstone or oyster reefs pro- jecting as isolated hills in "bad land" areas. Many of the reefs are composed almost entirely of organic calcite, chiefly oysters, firmly consolidated and in one place at least partially turned to marble. In other places, there are large areas com- pletely covered with oyster shells, anomias, pectens and barna- cles. These are weathered out free, and except for an etching from, the wind-blown desert sand, are in a perfect state of preservation. Much of the core of the mountain is composed of marble and quarrying operations on a prospective scale have been carried on at many places. Unquestionably some of it is very beautiful rock. The best fossil-collecting locality is on the south side of the mountain, a little west of the center in a wash called Alverson Cafion. Fossils occur there in many kinds of sediments, but the preservation is notoriously bad. Many of them can only be had as casts, while most of the others are so badly crystal- lized that the finer details of sculpture are obscured. The richest layers are sandstone, firmly cemented with calcite. Extraction of fossils from this material was found to be ex- ceedingly difficult except in a few favorably weathered surfaces. Age of the Deposits Various age determinations have been made of the Tertiary sediments on the flanks of Coyote Mountain usually referred to as "Carrizo Creek" which cuts through a portion of them. Conrad, with four species of Mollusca, thought the age was Miocene. Orcutt in 1890 supposed it to be Cretaceous, basing the decision upon the oysters and corals. Vaughan in 1900 with two species and a subspecies of coral gave the age as "doubtfully Cretaceous." Arnold in 1906 called it Miocene and correlated with the Etchegoin of central California which he also called Miocene, but which has been determined to be lower Pliocene. 434 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Vaughan in 1910 gave the age as lower Miocene as de- termined by Messrs. Dall and Arnold. Kew in 1914 stated that "The echinoderm fauna seems to indicate a comparatively late age, as several of the forms are very closely related to species living in the Gulf of California at the present time." In 1920 he referred all of them to the Pliocene. In 1916 Nomland referred the coralliferous beds to the Pliocene. Vaughan in 1917 stated that 'The fauna of Carrizo Creek is related to Pliocene and Post-Pliocene faunas of Florida and the West Indies and can scarcely be older than lower Pliocene." Dickerson followed in 1918 with a Miocene age determina- tion correlating the sediments with the Gatun formation of Panama. It is quite evident that considerable diversity of opinion as to the age has existed. A critical study of the Mollusca con- tained in the various collections I have examined, leads me to agree that the age cannot be greater than lower Pliocene and I am much inclined to the belief that the greater portion is middle and upper Pliocene. There appears to be good reason to suspect that more than one Pliocene formation is represented on the flanks of Coyote Mountain. Very little reason exists for the placing of the coral reef, the lowermost exposed fossiliferous stratum, with the great oyster reefs of the upper part. Names of Formations For a long time the deposits about Coyote Mountain have been called "Carrizo Creek" beds, or "Carrizo" formation; the latter was proposed definitely in 1914 by Kew," but Vaughan® has shown that these names are inapplicable because of prior use elsewhere. This is to be regretted, but it seems that current usage demands a different name. Since we are unable as yet to correlate definitely any of the fossil bearing strata with any named fonnation elsewhere, I would propose that it be known as the "Imperial Formation" in the future. •Univ. Calif. Publ. Geol. Vol. 8. •U. S. Gcol. Surv. Prof. Ppr. 98, 1917, p. 367. Vol. XIV] HASM A— COYOTE MOU.VTAIN I'OS^JL:^ 435 The tyi>c locality should be tnken as the coral reef exposed in Alverson Canon on the south side of the niountaiTi. This coral reef has a distinctive fauna. It is succeeded by about 200 feet of very fossiliferous calcareous sandstones for which I would propose the name "Latrania Sands." It is this formation which contains the large general assemblage of marine Mollusca, a representation which indicates the presence of pure ocean water. Above the Latrania Sands there are enormous de^x^sits of clay, the i>eculiar properties of which may make it of com- mercial value at some future time. In order that these may have a name for reference I would propose that they be called the "Coyote Mountain Cla3'^s." They are extensivel)'" developed over wide areas but the type locality has been select- ed in the foothills bordering the southeast slope of Coyote Mountain. Above these clays, and interbedded with them near the top to some extent, are extensive deix)sits of oyster shells for which the name ''Yuba Reefs" has been selected. The type locality has been chosen as a prominent hill made up of the material, thoroughly cemented and partially metamorphosed, located on the east em\ of the Coyote Mountain uplift. A gap between the hill and the mountain affords a good trail from Coyote Wells on the San Diego-El Centro Highway to the north side of the mountain. The same reefs are found on Yuha Buttes, Superstition ^Mountain, Signal Mountain, and especially near where Carrizo Creek flows out of the mountains to the westward. ,The Yuha Reefs are followed by an enormous thickness of silt deposited in the freshwaters of the ancient Lake Coahuila, an appropriate name for which is the "Coahuila Silt." It is exposed where the San Diego-El Centro Highway crosses New River about a mile west of El Centro. The total thick- ness of these silts is not known but they contain freshwater fossils to the base of the exposure indicated. Thus, according to the above nomenclature, Conrad's fossil mollusks came from the Yuha Reefs. Kew's echinodenns are from the Latrania Sands; and Vaughan's corals from the Imi^erial Formation. It is believed that further work will March 23, 1926 436 CALIFORNIA ACADEMY OF SCIENCES | Proc. 4th Ser. necessitate further subdivision rather than a consolidation of the above formations. In this connection it is proper to add that Coyote Moun- tain has been called "Carrizo Mountain" in some reports. Also Fish Creek Mountain, the next one to the north of Carrizo Creek, has been called "Black Mountain," "Barrett Moun- tain," and "Fish Mountain." Oil Possibilities At various times attempts have been made around the flanks of Coyote Mountain to obtain oil, but I think in every case, without adequate preliminary geological investigation. If this had been made, I can see no reason for the drilling of more than one well in that vicinity. This statement is based upon the following facts : 1. No adequate source of petroleum exists. While some exposed strata are very fossiliferous, all except the oyster reefs are far from being sufficiently so to be considered as a source of petroleum in commercial quantities. The oyster reefs have no adequate cover. The great deposits of shales and clay shales are barren of organisms. The basal marbles cannot be considered at all in this connection. 2. The structure about Coyote Mountain is monoclinal; all strata dip away from the mountain. There is no known place for oil to accumulate. There is only one possible exception to this statement within a radius of five miles of the mountain, to my knowledge. Yuha Buttes, five miles to the southeast, is evidently an anticlinal, dome-shaped fold. But it was tested to a depth of over 1 100 feet many years ago without evidence of oil. Indeterminate Species The various collections studied have contained a consider- able number of species so poorly preserved that positive specific identification cannot be made. While it is true that leaving them out of the present list will give the impression that the complete fauna is smaller than it actually is, no useful purpose would appear to be served by including a lot of generic names. Vol. XI\ ] HAWNA—COYOTE MOUiWTAIN FOSSILS 437 The fauna of the PHocene beds of Coyote Mountain is a large one, and if it could be seen in its entirety, it would ap- proximate, probably, the present one of the Gulf of California in size ; but induration has proceeded to such a degree that only a small ^wrtion can be obtained unless some new localities with better preservation are discovered. Mere names of genera, derived from fragments, do not give a satisfactory picture of a fauna, but they are sometimes included in lists as padding. Space is now too valuable to warrant such procedure unless some other purpose can be served. Therefore, only those species have been included in the fol- lowing pages which could be identified with reasonable assur- ance of their correctness. No doubt inexperience has thus caused the omission of some species which might have been included had the author been more familiar with related faunas. This loss, however, is believed to be more than offset by the inaccuracies which would have resulted from attempts to place the fragments in question.

Dall''* listed the species as striata from the Bowden, Jamaica deposits, which were then thought to be Oligocene in age. Maury, however, continued to use the name paupercula for the fossils from Santo Domingo because "Sowerby's species has been so much used it seems best to retain it for the fossil." The figures of Pilsbry are as nearly identical with the Cali- fornia fossils as it appears necessary for them to be. Shape and size are very nearly the same. The fossils are somewhat eroded and crystallized, but it is possible to see that there were six spiral lines on the base and three near the apex of those best preserved. The apical umbilicus is wide and the angula- tion of the shell there is marked. The specimen illustrated herewith measures 26.1 mm. in altitude and 14 mm. in diam- eter. The loosening of the outer layer of the shell has pro- duced a columellar channel which, being artificial, should be ignored in comparisons. There does not appear to be a Gulf of California living "analogue" of this West Indian form, nor has anything like it been recorded from the Isthmuses of Tuhauntepec and Panama fossil deposits. Whether present- day taxonomists would give the Jklediterranean form so wide a geographic and stratigraphic range as this cannot be answered, but, accepting the work of the past, no biologic reason could be discovered in the fossils to warrant their separation.

Some of the fossils are almost smooth on the body whorls, a senile character apparently, while others are heavily cancellated. Between the two fonns, there is every stage of intergradation. The name, C. tirceolata Hinds ap- pears to have been applied to the strongly marked forms, and if this name be admitted, it should certainly be applied to some of the above fossils. The largest of the above listed specimens (S. D. S. N. H. coll. ) is 45 mm. in altitude and 23 mm. in diameter, but living specimens have been seen which considerably exceed these dimensions. The Gatun species, C. dariena Toula," seems to be strongly marked constantly, and differs otherwise from the Coyote Mountain fossils. 4. Cassis subtuberosa Hanna, new species Plate 20, figure 8 ; plate 29, figures 2, 3 Shell with a single row of low, close-set tubercles around the periphery of the last half of the last whorl ; spiral striation absent but last part of last whorl irregularly longitudinally ribbed ; spire moderately elevated, conical ; columellar face and expanded outer lip roughly triangular in shape ; 1 1 low lamel- lar teeth on the outer lip; columellar face irregularly ridged in the lower part ; the upper projecting angle somewhat eroded due to wear before the specimen was preserved. The species is most closely related to C. tuberosa Linnaeus. In addition to the type specimen two others are in the series of shells examined, but only one is of value in defining the species. "Jahr.

Vol. XIV] HANNA— COYOTE MOUNTAIN FOSSILS 445 This is a younger individual than the type and three indistinct rows of tubercles are visible on the body whorl. This suggests C. sulcifcra Sowerby,'^ but all three rows in that species con- tinue to develop to maturity. The upper projection of the enamelled columellar face is ex- tended almost exactly in the same proportion in the younger individual of subtitberosa as in C. tuberosa. This specimen indicates that there may be intergradation between the fossils and living forms if sufficient material were at hand for study. In neither of the fossils are the tubercles massive nor do the earlier ones show in the aperture of the shell as in C. tuberosa. Type and paratype: In the collection of the University of California from Loc. 738, Alverson Canon, Coyote Mountain, Imperial County, California. Another very poorly preserved specimen is listed under locality 701 (C.A.S.). Casts of the type and paratype are Nos. 1799 and 1800 (C. A. S. coll.). The finding of this fossil Cassis is believed to be the first definite record of one of the larger species of the genus on the west coast of North America, either living or fossil. So far as I am aware, none has been found in the Tertiary deposits of the West Indies or the southern states, although three species are found living there at the present time. C. tuberosa was not found by F. M. Anderson in any of the fossil deposits of Colombia or the Isthmus of Panama, but recent specimens were secured by him at the former place. One of these has only five tubercles on the periphery of the last whorl. Two other specimens in the California Academy of Sciences from the Bahama Islands have eight and six respectively. In every case these assume the character of blunt spines and are rather distantly separated. 5. Cerithium incisum Sowerby Lampania inctsa Sowerby, Thes. Conch. Vol. 2, 1855, p. 868, fig. 152.

A single adult and 17 young of a large cone from Loc. 738, have been referred to this living species of the Gulf of Cali- fornia and southward. The large one has been somewhat crushed out of shape and otherwise is imperfect, but the cor- rectness of the identification is fairly certain. This specimen is 89.7 mm. in altitude and 52 mm. in greatest diameter. While the identity of it with the living form is advisable, there is considerable doubt as to the correct name which should be applied. C. fergusoni was described from a living specimen from Panama and has since been found at numerous localities on the west coast. The California Academy of Sciences' col- lections contain a good series. In them there are also several fine specimens from the Gatun beds of the Isthmus of Panama. They appear to be identical with the species from there which was named C. mollis by Brown and Pilsbry. Both series show some variation in height of spire and the sculpture between the sutures. In the original description of C. mollis, comparison is made with Conns haytensis Sowerby,^" a species which was described without illustration from the Santo Domingo Miocene. Maury,^^ however, figured it and remarked upon the closeness of C. mollis to it. If they should prove to be the same, as seems likely, C. haytensis will replace both names, fergusoni and mollis. The young examples from locality 738 are all more or less imperfect and could, with equal propriety, be determined as any one of a dozen named species. Through crystallization they have lost their finer sculpture and many of them are crushetl and broken. The shape does not deviate from that of fergusoni sufficiently to be noted herein. '- Quart.

The other specimens are small casts not readily determinable with certainty, but presumably the same. Even the best preserved has so crystallized that the minute sculpture cannot be discerned and apical characters have been lost. Burnett Smith^*^ in treating of the morphology of the genus gave apical characters for the separation of most of the living species, but did not indicate the constancy of sculpture in a large series of shells from one locality. East American paleontologists do not seem to have adopted the genus-name Ficus Bolten, in place of Pyriila Lamarck, as proposed by DalP^ in 1909. Western students have generally accepted the change and their example is followed herein, without, however, giving consideration to the merits of the case. F. decussata is the name generally used for the common, species found living in the Gulf of California. A large series collected in 1921 by the Expedition from the Academy has been available for comparison and within the lot, variation in sculpture is sufificient to cover the Coyote Mountain fossils. 13.

Brown & Pilsbry apparently had but a single specimen upon which to base their original description and therefore were unable to make any statement as to the vari- ation or the relationship of the species. Attention is there- fore called to the fact that the spiral striation which they men- tion as being present on the sutural band can scarcely be dis- cerned in some specimens while in others it is very plain. The tiumber of ribs on each whorl varies from 14 to 18 in speci- mens from Gatun and the one from southern California has 20. Spiral threads below the sutural band var}' in number from three to five.

Some specimens of T. pedroana Dall have convex spires like T. gausapata, but they are rare and differ in sculpture. So far as a large series of the former show, the two species cannot be connected by a series of intergrades. The fossils seem closer to the east coast Pliocene and recent species, T. dislocata (Say) than to the west coast forni. T. martini English, from the Fernando Pliocene of California is a shell similar in size to gausapata but the vertical ribbing is much more pronounced in most specimens and the spiral lines are obsolete or nearly so. 29.

Variation among them has been so great that many names have been applied. DalP*' has stated that these . . . "will probably be diminished when sufficient material has been brought to- gether and carefully studied." On actual comparison of the western shells with Miocene material from the Chipola Marls of Florida some specimens of the latter are found which af>- proach very closely. These I take to be T. terebriformis Dall,*^ an unfigured species. The only observable difference which appears to be constant is the lack of nodes on the spiral ridges. Size, shape and other sculpture appear to be identical. The representative of the group in the Gatun formation of Panama is T. altilira Conrad,"" the spiral ridges of which are high, and very decidedly crenulated. In no instance is inter- gradation with the California specimens approached. Another closely related Miocene species is T. tornata Guppy^® of Santo Domingo. The ridges on that species also are beaded and it appears never to reach such a large size as the others which have been mentioned. From the Pliocene of Florida comes the large species, T. perattcnuata Heilprin*" which belongs to the same group but appears to differ from the southern California species to a greater extent. In it there is a greater tendency to accessory spiral ribs, some of them almost equaling in strength the two major ones. Species of undoubted alliance are not lacking in present seas although none of them appears to reach the large size of the fossils. Thus T. exoleta Linnaeus of the Gulf of Mexico and T. coopcri Carpenter of the west coast are similar in general form although both appear to be constantly different. The spiral ridges are much less heavy but they remain just two in number. The latter species has been found in Pliocene de- posits of Lower California, as well as living.** "Trans. Wag.

I have had no living specimens from the west coast for comparison, but the only difference between the fossils and living east coast material seems to be in the weaker spirals of the former. The specimen from the San Diego Society of Natural History shows only a ridge for the anterior row of spines. It is badly broken but measures 93 mm. in altitude and 83 mm. in diameter. The U. S. Geological Survey specimen has a single row of spines. And the young example from lo- cality 682 (Calif. Acad. Sci.) has a row of spines with a ridge below. The columellar plaits number either four or five. With a large series of living and Pleistocene shells from the east coast of Colombia available for comparison, it does not seem that there are specific differences Ijetween them and the California fossils, but the problem must remain open until living specimens from the west coast can be obtained.

Vol. XIVI HANNA— COYOTE MOUNTAm FOSSILS 459 When the above list was made out, it was believed to be best to unite all the plicate oysters of the Coyote Mountain region under one name. Sufficient comparative material was lacking for a logical separation of species. Therefore the collections listed from the U. S. Geological Survey and the University of California contain some specimens of 0. hecriimnni as well as O. vespertina. Since the list was made and the collections returned, a large amount of comparative material, living and fossil from the Gulf of California region has been obtained, and it is believed that a separation into two species can be made with reasonable certainty, the large one taking- the name O. hcermanni. Ostrca vespertina was first described from San Diego (Con- rad, Journ, Phila. Acad. Sci.) in 1853, but was not figured until Conrad considered the specimens obtained by Blake from the Colorado desert where Carrizo Creek flows out of the Laguna Mountains upon the valley floor. Subsequent collect- ing at San Diego by many experienced workers has resulted in obtaining but one plicate oyster and that is the one described by Gabb*"^ from Cedros Island as O. veatchii. That the latter is synonymous with vespertina can scarcely be questioned. The identity was pointed out by Dall in 1898*'" and concurred in by Arnold in 1909.°^ The former considered both names as well as O. heermanni Conrad, the equivalent of O. haitensis Sower- by, 1850, an east American species. The later views of Dall regarding the living species of western oysters are set forth in a little paper published in 1914."* Here we find 0. veatchii given the status of a species. Whether the Carrizo Creek and Coyote Mountain oysters called vespertina are the same as San Diego specimens ori- ginally given that name cannot be stated with certainty, but seems probable. Around the flanks of Coyote Mountain the shells form great reefs, thoroughly consolidated and cemented, in some places already partially converted to marble. Such metamorphism is unusual for such late deposits in western North America. «Geol. Surv. Calif. Pal., Vol. 2, 1869, p. 35, pi. 11, fig. 61. « Trans. Wagner Free Inst.

It is one of the most common species in the Coyote Moun- tain region. Specimens were seen in the black limestone which caps a southern slope of the mountain east of Alverson Canon where the matrix was so hard that the shells could not be ex- tracted, and the stone rang like tempered steel when struck with a hammer. No specimens were seen higher up in the sequence of strata than that, but from there downward to the basal exposure (the coral reef in Alverson Canon) the shells were everywhere in evidence.

There is only one west coast species with which the scul^v ture of this can be compared, Pecten estrellanus (Conrad) of Miocene and lower Pliocene strata. That species is more in- flated, longer than high, and the ribs extend entirely to the beak ; moreover, the ribs are squarish and interspaces chan- neled on each side of the smaller riblet. Twenty-seven specimens were obtained from the coral reef of Alverson Canon, Loc. 681, and one from Loc. 683, both of the California Academy of Sciences' series. The reef is a well- marked feature of the topography as one ascends the caiion, yet it does not appear to have been explored heretofore, since none of the numerous collections seen has contained this species. Like P. sancto-ludovici the specimens are more or less poorly preserved and usually somewhat crushed out of shape. Vol. XIV] HANNA— COYOTE MOUNTAIN FOSSILS 473 55.

Rarely are examples of any species from two localities so nearly identical. The sculpture of the species at once recalls hastatus and if only the right valve were known, it could be easily taken for that. The number of ribs is about the same, likewise the ser- rations of the riblets ; but there is no tendency in sanctp- ludovici for the ribs to be double or in pairs. The main dis- tinguishing feature, however, is the fact that while the left valve only of hastatus has about nine ribs, in sancto-ludovici the number is the same as in the right. 57.

None of the above speci- mens had so many riblets between the main ribs as have been seen in some living shells, but this is probably due to the small series; certainly some living individuals, unquestionably sub- nodosus, have as few riblets as these. As in P. etch^goini farther north, the strength of the nodes varies greatly in a series of shells. 58.

It is seen to be very irregularly spinose; con- centric sculpture is almost absent; the beak is very high and the ligamentary canal continuous to the apex. I have seen 12 names which have been applied to west coast Spondylidae, and there may be others. Most of these, how- ever, have been applied to various and sundry modifications of the forms known as pictorum and limhatus, no representa- tives of which appear in the fossil beds at the head of the Gulf. 62.

Both Gabb's and Guppy's mention of the species bostrychites are in publications which are very inaccessible and no one has thus far given a description of the species, since those authors wrote. Identi- fication would have probably been impossible had it not been for the fact that our specimens were compared directly, with Guppy's type of bostrychites and other material in the National Museum. This was done through the kindness of Mr. W. C. Mansfield. Giippy's type was a young individual similar to the one Maury) has figured. Ball's figure is of an older example, but neither of them shows the minute sculpture which appears to be characteristic ; at any rate, it is present on the type and others. At Loc. 738 (U.C.) and also at Loc. 685 (C.A.S.) a speci- men was secured. The former is the more i)erfect and has been figured. The spines are arranged in five radial rows, but they have been broken away so that their length cannot be compared with those of bostrychites. In the intervening spaces, there are from five to nine smaller radial ridges which become slightly spinose toward the outer margin of the shell. These are irregular in size. The surface is marked by very small, wavy, concentric lines which are broken into many papillae, particularly toward the center of the shell. The) hinge area is slightly heavier than in the specimens from Santo Domingo which were compared, but this is a variable character in the genus. The ligamentary groove extends to the apex. Apex not elevated or spiral. Valves of about equal size and con- vexity. In the latter respect the species differs from 6". scotti Brown & Pilsbry" and the larger species which they did not figure and therefore cannot be recognized. The specimen figured, although somewhat broken, measures 86 mm. in a line parallel to the hinge, and 99 mm, high. The larger specimen measures 115 mm. by 125 mm. but it likewise is imperfect. If perfect, the latter dimension would be in- creased by about 10 mm. "Proc. Acad. Nat. Sci. Phi!a.. 1912, p. 514, pi. 25, figs. I, 2. Vol. XIV) HANNA— COYOTE MOUNTAIN FOSSILS 479 63.

This identification of the single specimen of spatangoid echinoderm from locality 3919 (U. S. Geol, Surv.) is attended with some doubt because of poor preservation. The specimen is small; length, 32 mm. ; width, 25 mm. ; height, 15.6 mm. It is so eroded that none of the markings or plates remains but resembles in shape some specimens of Metalia spatangiis from the Gulf; of California. The lateral petals of the fossil are somewhat decumbent and may be the mark of a new species, but the writer is not sufficiently acquainted with the group to venture a description on such fragmentary material. Kew has recorded no species of the group from Coyote Mountain and apparently this is the first and only specimen that has been found there. One would naturally expect such forms as Meoma grancUs, but thus far they have not been found. Corals The coral fauna of the Coyote Mountain district is exceed- ingly interesting and has been thoroughly studied by Dr. T, W. Vaughan. No less than 12 named fonns are found in the various reefs.

Van Duzee. The present net income of the Academy, apart from funds received from San Francisco for the operation and mainten- ance of the Steinhart Aquarium, is about $80,000. Of this amount about $10,000 is annually applied to a reduction of in- debtedness and the rest is expended on scientific research' work and the upkeep of the Academy's exhibits. Both the Museum and the Aquarium are open to the public daily without charge. The wisdom of the arrangement with the lessee of the Academy's Market Street property made in 1909, according to which the rent is readjusted frequently, based on reappraisals of the value of the real estate, is amply demonstrated by the actual result. There was, as the result of such reappraisal in 1924, an increase in income due to this cause alone of $8,712. The gross income from this property in the year 1926 is esti- mated at $92,097 from which, to determine net income (with- out allowance for depreciation), there should be deducted $12,925, the interest on the unpaid balance of the loan secured by this property which now stands at $235,000, it having been reduced $15,000 in the past year. The Academy has received a number of valuable bequests and donations during the year which include the bequest of the late Henry M. Holbrook, preliminarily noted in last year's report of the President, of a notable collection of moths and 512 CALIFORNIA ACADEMY OF SCIENCES [Paoc. 4th Ser. butterflies together with $2,000 for the installation of this col- lection. A very handsome and instructive exhibit has resulted. Dr. Frank E. Blaisdell (under date of Aug. 22, 1925) pre- sented to the Academy his collection of over 100,000 speci- mens of Coleoptera. This donation of great scientific value has followed closely that made by Dr. E. C. Van Dyke in December, 1924, which, as noted in last year's report, is also estimated at over 100,000 specimens. Mr. Edward P. Van Duzee, Curator of Entomology, under date of August 4. 1925, presented to the Academy his collec- tion of more than 30,000 specimens of Hemiptera. This col- lection probably excels any other collection of this order in this country. In grateful recognition of these valuable donations Dr. Edward C. Van Dyke, Dr. Frank E. Blaisdell and Mr. Edward P. Van Duzee are now classed as Patrons of the Academy, Another important contribution to the material in the De- partment of Entomology was made by John E. Carey in Janu- ary, 1925. This consists of 500 specimens of Lepidoptera col- lected in Panama. Mr. Ogden Mills has added $1000 to sums previously con- tributed in order that the setting of the Grizzly Bear habitat group might be improved. The rearrangement of this group is now in progress. — the work being done with funds contrib- uted by Mr. Mills. The most notable scientific activity of the Academy during the past year was an expedition to the Revillagigedo Islands, of which a detailed account is presented in the report of the Director of the Museum. Thanks to the interest of the Secre- tary of the Navy, Curtis D. Wilbur, the cooperation and assist- ance of the United States Navy Department was secured and the U. S. mine sweeper Ortolan was detailed to convey the scientists to and from the islands. Sailing on April 15, 1925, each of the islands in the group was visited and the expedition returned on June 12, bringing much new information and valuable collections which will be studied with publication of results in due course. The Library continues to grow. Many new accessions of valuable publications and occasional rare editions of scientific Vol. XIV] GRUNSKY—PRESlDEh'TS REPORT FOR 1925 5I3 books have been made possible by a somewhat larger allot- ment of funds for the purpose than usually available. The Steinhart Aquarium has been operated with scrupulous adherence to the requirement that expenditure be kept within the amounts of funds allotted by the City and County of San Francisco for its operation. The Academy has exercised great care in keeping its requests for funds as low as compatible with efficient management. Nevertheless, the allotted funds have been somewhat below the actual needs, with the result that there has had to be some curtailing of the program of collecting specimens. The continued popularity of the Aqua- rium evidenced by large attendance is gratifying proof of its value as an educational adjunct to the Academy and as a source of much pleasure and benefit to multitudes of people. The Academy, through a Committee under the leadership of Mr. M. Hall McAllister, continues, among other activities, its cooperation with other organizations in the preservation of wild life. In this matter, as in any others related to the natural sciences, the Academy is at all times ready to act as trustee and would be only too glad to be placed in command of facilities that would permit large increase of its activities. The need for more space for the research work of the cura- tors and their assistants and for natural history exhibits, and the need of an adequate auditorium, grows more pressing from day to day. Year after year in our annual reports at- tention has been called to this pressing requirement to permit the Academy to function properly. Aside from a small annual sinking fund (about $10,000) which is being applied to a re- duction of the indebtedness which was incurred when the Academy's Market Street property was improved by the erec- tion of a modern 10-story office building, all of the Academy's income is expended in research work and in maintaining and adding to its research collections and exhibits. The public is, perhaps, not as fully advised of the contributions which the Academy has made to the advancement of science as it should be. The results of studies along lines of natural history do not as a rule lend themselves to spectacular display. The hardworking entomolgist, ornithologist, botanist, herpetolo- gist, paleontologist, ichthyologist, as the case may be, is con- tent to find the results of his studies made of record in printed 514 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. form for the use and benefit of mankind. His is the satisfac- tion in the doing and in the knowledge that in some measure he has broadened the foundation on which civiHzation rests. The great mass of the people, however, do not see what is being so laboriously and so well done on most slender means. As this year marks the tenth anniversary of the completion and opening of the first unit of the Academy's museum build- ing in Golden Gate Park, it will be fitting to review briefly the activities of the Academy during this decade with the hope that the further financial assistance for increased activity and usefulness may not be too long deferred. Before presenting this condensed review, a word may not be out of place in appreciation of the generous endowments and bequests which have made the Academy's activities possi- ble. These are small in the aggregate compared with some of the munificent endowments of similar institutions and colleges of learning on the Atlantic Coast and in the Middle West. There is to be noted, for example, the recent Munsey bequest of some $20,000,000 to the Metropolitan Museum of Art at New York ; the $2,000,000 gift by Mr. J. G. Shedd of Chicago for an aquarium; $1,000,000 endowment by Henry T. Towne of New York for a Museum of Peaceful Arts ; Julius Rosen- wald's $1,000,000 toward the establishment of an Industrial Museum ; and the Wilson Catherwood bequest of $250,000 to the Zoological Society of Philadelphia, besides more than $70,000,000 in recent years which have been placed at the dis- posal of universities or to be used in establishing new institu- tions of learning. The endowments and bequests have, like all similar provi- sions for repositories of knowledge and for research, helped not alone to make for the progress of mankind, but, also, to establish that balance so essential from the economic stand- point between the producing class and the non-producers or consumers, which is every country's safeguard of continued and dependable prosperity. It is obvious that practically all outgo for scientific research gets into local circulation. It goes for the necessities of life, for food, shelter, clothing, edu- cation, recreation, transportation and what not. It goes from hand to hand at least 12 times in a year. Our little budget, for example, of $75,000 to $80,000 will probably account for Vol. XIV] GRUNSKY—PRESIDENT'S REPORT FOR 192$ 515 nearly $1,000,000 of business annually within California, to the advantage of both middleman and producer. From the economic standpoint, therefore, the liberal endowment of such institutions as this Academy is amply justified and no more appropriate outlet for large accumulations of wealth than in the making of such endowments and bequests to worthy in- stitutions could possibly be found. The first large scale aid came to the Academy from James Lick, to whom it is indebted for the Market Street lot between Fourth and Fifth Streets now worth over $800,000, the build- ing on which produces a net annual return of about $75,000. Next in the order of magnitude is the Ignatz Steinhart be- quest of $250,000 for the Aquarium, to whose popularity a phenominally large list of visitors bears ample and gratifying testimony. Then there is a fund of $20,000 contributed by Charles Crocker to aid in compensating those engaged in scientific studies; $5,000 contributed by Wm. Alvord for use by the Department of Botany and a $10,000 bequest by John W. Hendrie to assist in publishing papers on scientific subjects, besides a large number of donations for the installation of habitat groups and other exhibits ranging in amount from $50 to over $8,000, but which amount in the aggregate to more than $40,000. Among the valuable collections which have enriched the Academy's stock of material in its various departments are the following: Collections donated or bequeathed Hemphill Collection (shells) John W. and Joseph Mailliard Collection (ornithological and oological) Kleeberger Collection (botanical) E. C. Van Dyke Collection (entomological) F. E. Blaisdell Collection (entomological) E. P. Van Duzee Collection (entomological) \V. G. Wright Collection (entomological) W. Otto Emerson Collection (ornithological) John Van Denburgh Collection (ornithological and oological) John Van Denburgh (library) L. S. Smith (library) Barton W. Evermann (library) 516 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Seb. Collections purchased znnth contributed funds Edward H. Taylor (herpetological) Prager Collection (botanical) And now as to a summary of what has been accomplished in these recent years : 1 . The first unit of the museum building of the Academy in Golden Gate Park was completed and dedicated in 1916. 2. The Steinhart Aquarium as an adjunct of the Academy's building's in Golden Gate Park was completed and opened to the public in 1923. 3. The available 18 large-size alcoves (17 in the museum building and one in the aquarium) have been filled with high class exhibits of birds and mammals in natural environment. 4. The research collections of material in the several de- partments have made steady and in some departments phe- nomenal growth, so that, despite the almost complete loss of material in the fire of 1906, these collections are now quite notable as will appear from the following brief summary. The Botanical Department of the California Academy of Sciences was not reestablished until 1912. From the nucleus of types saved from the great fire, the collection has grown so as to fill 81 cases, 31 of which on account of restricted space have had to be placed in the hall of the research wing of the Museum Building adjoining the Botanical Department. There are now 138,432 specimens in the herbarium, mounted, num- bered and stamped. It is the most cosmopolitan collection on the Pacific Coast and is unsurpassed in its collection of the exotics which are cultivated out of doors in California and which represent plants from all parts of the world. It is considered the Pacific Coast authority on these plants and is constantly consulted. The herbarium is also rich in Alaskan and Yukon plants and probably has the best collection on the Pacific Coast. Our Californian collection is fairly complete though still surpassed by collections in other herbariums of the Pacific Coast which have had much longer time in which to accumu- late material and which have had many more collectors. Valuable additions have been made by exchange with some of the large herbariums of the world. The Royal Herbarium Vol. XIV] GRUNSKY— PRESIDENT'S REPORT FOR i9^5 Sl7 at Kew, England; the National Herbarium at Washington; the Gray Herbarium, Cambridge, Mass. ; the Arnold Arbore- tum, Jamaica Plain, Mass.; and the New York Botanical Garden have all been most generous in making exchanges. The greatest donation was that of the Prager Herbarium, which was purchased in 1921 through the generosity of Wm. H. Crocker, Wm. F. Herrin, A. F. Morrison, J. C. Augsbury, J. D. Grant, Wm. M. Fitzhugh and Wm. C. Van Antwerp. This was one of the largest private herbariums in Germany and added about 26,000 species and over 50,000 specimens to the Academy's herbarium. This collection is especially rich in Australian, South African, Asia Minor and Arctic and European species and contains many paratypes. Doctors Fred and Charlotte Baker donated a valuable col- lection which they made in Japan and China. Professor R. Kleeberger donated his herbarium, which included his own collections made in Connecticut and also a set of the Kellogg and Harford collections made in California in the 1860's. Mrs. Abbott gave the Academy her deceased husband's collec- tion known as the Dr. E. K. Abbott collection. It is rich in specimens from Monterey County, also in a collection from France made many years ago in the region memorable as the chief seat of the world war. Valuable collections from Chile and from China have been secured by purchase. The specimens collected on the various expeditions elsewhere noted have added many species to the collection besides furnishing valu- able material for exchange. The Academy's paleontological collection was entirely de- stroyed in 1906. It has since then been restored to greater size. The specimens run into millions. Invertebrate paleon- tology of western North America is better represented in the Academy's collection than anywhere else. Much comparative material is in the collection obtained from many typical locali- ties elsewhere in the world. The collection of organic shales, which have a definite relation to the pretroleum industry, is by far the largest in existence. In the collection of type ma- terial the number of catalogued specimens of various kinds now exceeds 2000. The growth of the entire paleontological col- 518 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. lection is reported by the Curator to have made a phenomenal growth in the last ten years. Because of inadequate space in the main laboratory it has been necessary to store tem[X)rarily many hundreds of thousands of specimens in the almost inac- cessible basement of the Museum building. The Academy's ornithological collection is l^est developed in marine birds, shore birds and ducks and geese.

XIV] GRUNSKY—PRESIDENT'S REPORT FOR rg^S 519 Of Mammals there are in the Academy 5250 si)ecimens (skins and skulls). Among the principal accessions of these are to be noted : W. W. Price Collection, 991 skins, small mammals from Eldorado and Mono counties ; and Douglas County, Nevada. H. O. Jenkins Collection, 506, chiefly Monterey and Santa Clara counties. Mr. A. K. Macomber, Gorilla from Belgian Congo, July 25, 1924. Lower California Expedition, 1921, 70 specimens. Galapagos Expedition, 1905-06, 120 specimens. During the past ten years the Academy's Department of Entomology has grown from a small unorganized collection until it now ranks among the large collections of the country, containing approximately 500,000 specimens, and, so far as west American material is concerned, probably takes first rank, with a very large proportion of its material carefully deter- mined and well arranged in systematic order and therefore available for comparison and study. The following valuable collections, as already noted, have recently been added to the Academy's material : The E. C. Van Dyke Collection of over 100,000 specimens. Coleoptera. The F. E. Blaisdell Collection of over 100,000 specimens. Coleoptera. The E. P. Van Duzee Collection of over 30,000 specimens. Hemiptera. John E. Carey Collection of over 900 Lepidoptera. The Academy's collection of reptiles and amphibians has been re-built since 1906. It now numbers over 59,000 speci- mens and is one of the largest in America. The collection of Galapagos tortoises is the largest and most complete in exist- ence. The collection from the Pacific Coast is unsurpassed by any other museum. The oriental collections are large and valuable. The Academy's library, too, is notable. This now consists of an extensive and valuable collection of books, periodicals and pamphlets on all branches of natural history and related subjects. For a fuller understanding of the work which has been ac- complished by the Academy, reference should be had to its 520 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. publications, of which the enumeration elsewhere in this re- port of the publications in 1925 gives a fair idea. This report would become too extended to attempt a review of the pub- lished material, even though restricted to the last ten years only. It is a pleasure to be able thus to present in condensed form the results of the Academy's activities and it is only necessary to refer to this summary to show how enthusiastic and able has been the work of the Academy's curators and their assist- ants. For them and for the Academy itself let me hope for further continuous and generous encouragement and support by the public whom the Academy is endeavoring to serve. To all who have in any way contributed to the Academy's activi- ties and successes, it makes grateful acknowledgment. Vol. XIV] EVERMANN— DIRECTOR'S REPORT FOR 1925 521 XX REPORT OF THE DIRECTOR FOR THE YEAR 1925 BY BARTON WARREN EVERMANN Director of the Museum and of the Aquarium The annual report of the Director for the year 1924 was presented to the Academy at the annual meeting, February 18, 1925. The scientific and educational activities of the Museum were maintained during the year 1925 in a satisfactory manner. The members of the scientific staff have been active not only in adding to the collections in their respective departments but also in arranging and classifying the collections and in re- search work. Personnel The personnel of the Museum staff has not greatly changed. Mr. Frank Yale, who had been in the service of the Academy many years, died March 12, 1925. Miss Margaret Dold, Li- brary Assistant, resigned May 28 to accept a position in the Mechanics Institute Library; Frank Ashworth, assistant jani- tor, left January 8, 1925, and was succeeded by Ralph Borden January 12, who remained until February 22, when he was replaced by M. D. Phillips, who remained only a short time when William E. Nicherson served a few days, when he was followed by C. A. Bellas June 1 to August 31, Milward Lavin July 13 to September 4, and Hugh R. Jones September 12. On July 1, the Department of Fishes was established with H. Walton Clark as Assistant Curator. The employes of the Museum on January 1, 1926, were as follows : Dr. Barton Warren Evermann, Director and Execu- tive Curator of the Museum, Editor of the Academy publica- tions and Director of the Steinhart Aquarium ; W. W. Sar- geant, Secretary to the Board of Trustees; Miss Susie M. Peers, Secretary to the Director ; Joseph W. Hobson, Record- ing Secretary; Mrs. Constance W.

Accessions to the Museum and Library The accessions to the museum and library have been, as in former years, many and valuable. An itemized list is given in the appendix to this report (pp. 549-559). A few of the more notable are mentioned in the President's report (p. 516). Cooperation with Public and Private Schools, with Other Institutions, and with Individuals Cooi^eration of the Academy with the schools, other institu- tions, and individuals continues close and mutually helpful. An arrangement was made with Mrs. Anna V. Dorris. in charge of visual instruction in the public schools of Berkeley, whereby the following portable habitat groups were prepared for use in the Berkeley public schools: Western Robin. Western Meadowlark, San Francisco Towhee, California Shrike, California Woodpecker, Gila Woodpecker, Barn Owl, Vol. XIV] EyERMANN— DIRECTOR'S REPORT FOR 1925 523 Marsh Birds, Spring Pocket Mouse, Cliickaree, Golden- mantled Ground Squirrel, California Ground Squirrel, and Weasel. These have been in constant use during the year. It is hoped that other groups may be prepared this year. Visitors to the Museum in 1925 The total number of visitors to the Museum in the calendar year 1925 was 553,423, the greatest in the history of the Museum with the exception of 1924, when it was 646,033. The number of visitors by months and years since the open- ing, September 22, 1916, is shown in the following table : Month 1916 1917 1918 1919 1920 1921 1922 1923 1924 1925 January 23170 25260 17241 27013 25755 19038 15270 32364 34989 February 22058 23698 17586 23450 25679 18534 20529 44439 29295 March 31606 26810 27397 25419 28279 27922 26341 39935 39168 April 32175 23274 25994 32208 24939 36057 21911 41332 40257 May 26154 26391 28369 37107 25517 27237 37597 48152 38137 June 32123 29843 32248 36207 29406 27131 39511 58281 51775 July 37193 31420 48028 52492 43186 36263 64530 91329 69921 August 24619 31137 43730 53470 39422 34787 50849 105130 77847 September . 16448 27866 29847 34007 42013 31458 28408 69870 82814 637i7 October .. 36933 20629 14743 30463 33500 24861 19459 66894 43074 40418 November . 27718 21810 8531 25246 19347 18593 19080 48766 37611 35634 December . 15002 21693 19588 21188 21340 15062 13339 36707 21572 32245 Total... 96101 321096 290542 351497 403566 332157 307255 498775 646033 553423 Total number of visitors since opening, September 16, 1916, has been 3,800,445. The public and private schools of the state continue to avail themselves of the educational uses of the Museum and the re- search collections. The number of schools visiting the museum is so great that we cannot print the list, much to our regret. The following summary must suffice : Schools of San Francisco : Total Number Visiting Pupils 5643 Total Number Visiting Teachers 169 Total Number Visiting Classes 184 Schools Outside of San Francisco : Total Number of Pupils 1373 Total Number of Teachers 48 Total Number of Classes 55 5643 1373 7016 524 CALIFORNIA ACADEMY OF SCIENCES [Piioc. 4th Ser. Museum Activities and Growth The past year has witnessed commendable activity in each of the several departments of the Museum. The various cura- tors and their assistants have shown great zeal and industry and have made excellent progress in the orderly arrangement and care of the collections in their charge. The field work was unusually extensive and productive, as set forth in detail in the respective departmental reports; mention need be made here of only a few of the more notable activities. The U. S. S. Ortolan Expedition of the California Academy of Sciences to the Revillagigedo Islands was one of the most important ever sent out by the Academy. Our scientific stafif for several years had been casting longing eyes toward that interesting group lying 300 to 600 miles off the Pacific coast of Mexico. As no very careful study had ever been made of the fauna and flora of those islands, it was believed that an expedition to them would yield results of considerable scien- tific importance and interest and add greatly to the natural history collections of the Museum. Upon making our wishes known to the U. S. Navy De- partment, Secretary Curtis D. Wilbur very generously detailed the U. S. S. minesweeper Ortolan for the use of the Academy in making the survey. The Ortolan outfitted at Mare Island Navy Yard, from which place she sailed on April 15, with M, M. Nelson, Lieu- tenant, U. S. Navy, in command. The Academy was represented by the following: Dr. G. Dallas Hanna, curator of paleontology, in charge; Mr. Joseph R. Slevin, assistant curator of herpetology, assistant chief; Frank Tose, chief taxidermist; Hartford H. Keifer, assistant curator of entomology ; Eric Knight Jordan, assistant curator of paleontology ; H. L. Mason, botanist ; John T. Wright, col- lector in ornithology and mammalogy; Raymond Duheni, offi- cial photographer. Upon arriving at San Diego, where the Ortolan stopped to take on certain supplies, the scientific staff was joined by Pro- fessor Francisco Contreras, Director Museo Nacional de Mexico; Dr. Octavio Solis, Director of the Botanical Garden Vol. XIVJ EVERMANN— DIRECTOR S REPORT FOR I9^s 525 of Chapultepec, Mexico, and Professor Jose Maria Gallegos, who accompanied the expedition as representatives of the Mexican government and as guests of the California Academy of Sciences. Mention should be made of cooperation with the Scripps Institution for Biological Research whereby the Academy un- dertook to secure for the Institution samples of water and plankton at intervals along the route of travel. A detailed general report of the expedition will be published soon.^ The extensive collections obtained have been assigned for study and report to specialists in the various groups ; their reports will be published in the Academy's Proceedings. Let it suffice to say at this time that the Expedition visited each of the islands of the Revillagigedo group (Clarion, Socorro, Roca Partida and San Benedicto), also Guadalupe Island to inspect the elephant seal rookery there, several islands of the Tres Marias archipelago, and a number of islands and stations in Lower California were visited en route northward and valuable collections made at each. This expedition, which re- turned to San Francisco June 10, is regarded as the most im- portant and most successful the Academy has ever sent out. Curator Mailliard of the Department of Ornithology and Mammalogy carried on field investigations in Siskiyou County, northern California, in May and June, in Placer County in June, July and December, and in Modoc County in September and October which resulted in important additions to our knowledge of the birds and mammals of those regions. In September and October Assistant Curator Miss McLellan carried on investigations in the states of Sinaloa and Mayarit, Mexico, during which she obtained an excellent series of the birds of tliat region which will prove of much value in the study of the collections obtained at the Tres Marias Islands by the Ortolan expedition. The growth of the Department of Entomology has been un- precedented. The additions to the Department's collections total more than 182,000 specimens. These include the Blais- dell collection of 100,000 Coleoptera and the Van Duzee col- lection of 30,000 Hemiptera. *This report has now been published. See Vol. XV, No. 1, pp. 1-113, of these Proceedings. 526 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. The additions to the collections in the Department of Herpe- tology numbers 3,253 specimens of reptiles and amphibians. The Herbarium under Miss Eastwood's able and energetic management has grown by leaps and bounds and now numbers more than 138,0CX) sheets of mounted specimens. The growth of the Department of Paleontology has been no less notable. The additions to the collections have been many and important, perhaps the largest being a very large and valuable series of minerals, fossils, and shells from the Philip- pines, Java, and Sumatra donated by Dr. Roy E. Dickerson, for several years the efficient and energetic curator of the Department. The Department of Exhibits has been active in the prepara- tion and installation of new habitat groups, chiefly of the small panel type, of which the following were completed within the year: California Woodpecker, Lazuli Bunting, Point Reyes Mountain Beaver, and Warner Mountain Cony. These are all excellently done and are very attractive exhibits. The Library has received a good number of accessions by gift, exchange and purchase, the total being about 967 volumes and about 100 pamphlets. For a number of years no binding was done, but this yeai 1163 volumes were bound at a cost of $1,614.75. Use of the Academy Library and Coi-lections BY Investigators and Students Use of the Academy library and the educational and research collections in the respective departments increases each year. While many of our members make use of the library, it is be- lieved that many others would do so if they realized how well the library is now supplied with current scientific periodicals, outing magazines, standard works of reference, and recen: authoritative publications in the various departments of physi- cal and biological science. It is hoped that our members may get in the habit of visiting the library when they desire in- formation in any department of science which can be found in our publications. Members and their friends are cordially in- vited to visit the various department laboratories and collec- tions when they wish to see any species of animal or plant of Vol. XIV] EWERMANN—DI RECTOR'S REPORT FOR 19^5 527 which we have specimens. In some of our tlepartments the collections are quite extensive and the visitor will probably find specimens of the particular species he wishes to see. Troop 20 of the Boy Scouts under Scout Master Harold E. Hanson, continues to meet weekly in the Academy's Audi- torium. The Academy is glad to be able to extend this cour- tesy to the Boy Scouts. Various other organizations have from time to time held special meetings in our Auditorium. Conservation of Wild Life The Committee on the conservation of wild life has been active during the year. The annual meeting of the Committee was held February 10, 1926, at which reports of the various volunteer observers were read. The census of big game ani- mals in each region where the Academy has an observer, is as follows : Mountain Sheep Inyo Mountains east of Big Pine, Edwin H.

Stein HART Aquarium The activities of the Aquarium for 1925 are fully covered in the report of the Superintendent. Let it suffice to say here that the Aquarium continues to grow in attractiveness and popular interest. The number of visitors for the year exceeded one million, including 382 school classes in charge of 350 teachers and containing 9,866 pupils. The interest which the public takes in the Aquarium is shown not only by the large number of visitors but in many other ways; for example, various f>ersons have given to the Aquarium within the year a total of 728 fishes, turtles, snakes and other live animals. On the other hand the Aquarium has given to schools and individuals during the year a total of 1,858 small aquarium fishes and other objects. 530 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser, The Academy in this way encourages the use of small bal- anced aquariums in homes and schools. Aquarium Personnel A number of changes in the personnel of the Aquarium have taken place within the year, due chiefly to resignations on account of the inadequate salaries paid. The employes with scarcely an exception have been and are efficient and indus- trious, performing their respective duties with enthusiasm and pride, but better salaries must be paid if we are to retain the most efficient. The present personnel is as follows : Dr. Barton Warren F^vermann, Director, part time ; W. W. Sargeant, Secretary, part time ; Susie M. Peers, Secretary to the Director, part time ; Mrs. Constance W. Campbell, office assistant, part time; Alvin Seale, Superintendent ; Wallace Adams, Assistant Superintendent ; Herbert Brandt, collector; Clynt S. Martin, chief engineer; Warren R. Hayes, assistant engineer ; P. E. Shepherd, assistant engineer ; S. J. Shenefield, carpenter and general utility man; Charles Brandt, chief attendant; C. E. Guidry, assistant attendant ; Robert J. Lanier, electrician and assistant attendant; Patrick O'Neill, janitor; Frank J. Maxwell, assistant janitor; Dora Arnold, doorkeeper; James Kavanaugh, police officer. Acknowledgments As in the past, many courtesies and favors of one kind or another have been shown the Academy by various organiza- tions and individuals. Space does not pennit individual acknowledgments of all, but the Academy is grateful to all who have helped it in any way and who have shown interest in its work. First, to those who have contributed to the educa- tional program of the Academy by giving one or more lectures in our Sunday afternoon and Wednesday evening lecture courses, the grateful thanks of the Academy are due; also to those who have donated specimens to the departments or books to the library. Special mention should be made of the deep interest which the Southern Pacific Company, the Atchison, Topeka and Santa Fe Railway System, and the Los Angeles Steamship Company have shown in the scientific and educa- tional work of the Academy, Each of these companies has Vol. XIV] EVERMANN— DIRECTOR'S REPORT FOR 19^5 53] rendered material assistance to members of the staff in con- nection with their field studies of the fauna, flora, paleontology and geology of the state, and in making collections of live fishes for the Steinhart Aquarium. With their generous co- operation the Academy is able to carry on its research and educational work much more comprehensively and thoroughly than would otherwise be possible. Publications by the Museum Staff The following bibliography lists the papers published by the Museum and Aquarium staffs in the year 1925. In the case of Dr. Hanna it includes his 1924 titles inadvertently omitted from the annual report for that year. Qark, H. Walton. 1. Lynvuea aurkulata (Linn.) in California. ', Vol. VI, No. 1, pp. 57-58, February 9, 1925. 3. Notes upon the Numerical Status of Rodent Populations in Parts of California. '. Two large collections were added to the Academy resources; specimens received from other sources number more than the average; the mounting and labelling of accumulated material made avail- able for study much which before had potential value only, and the addi- tion of new cases permitted the rearranging of the collections to be ad- vanced rapidly. Additions to the department collection during 1925, received through the ordinary activities of the department, numbered 27,301 specimens. In addition, two large collections were formally presented to the Academy which merit special mention. On August 22, Dr. F. E. Blaisdell presented to the Academy his entire collection of Coleoptera, numbering at least 100,000 specimens. These were given under the same conditions as was the Van Dyke collection presented last year, conditions that allow the donor the free use and control of the material during his life time, assures its permanent preservation, and, with the Van Dyke collection, places in the possession of the Academy a remarkably complete series of the beetles of North America, which, in the case of the western species, are repre- sented by exceptionally large and valuable series showing geographical and ecological variation. The other collection mentioned is the curator's private collection of Hemiptera numbering perhaps 30,000 specimens. This collection, accumulated through more than 30 years of systematic work on that order of insects, represents a very large proportion of the species known from America north of Mexico up to 10 years ago, and, added to the extensive collection of western Hemiptera already in the Academy collection, forms a representation in that order of insects perhaps unsur- passed so far as our North American fauna is concerned. Of the ordinary accessions of the year the largest item is the material taken by the curator's assistant, Mr. H. H. Keifer, on the Academy's ex- pedition to the Revillagigedo Islands, numbering 10,753 specimens. The work of determining this material has only just begun, but undoubtedly many new and rare species will be found in it. Other notable additions during the year were : from Mr. A. J. Bassenger, 2210 specimens includ- ing a large and interesting series of Diptera from Alaska; from Mr. C. L. Fox, 3,114 specimens consisting of Diptera and Coleoptera from eastern Washington and western Idaho and a valuable series of Hymenop- tera from Arizona; from Dr. E. C. Van Dyke, 1954 insects of orders other than Q)leoptera from Oregon and eastern Washington and other locali- ties; from Mr. J. C. Huguenin, 1870 miscellaneous insects; from Mr. Walter M. Giffard, 320 leaf-cutting bees from about Lake Tahoe, Cali- fornia; from Mr. E. A. Dodge, a collection of 478 tiger beetles made many years ago by his brother, Mr. G. M. Dodge, and including many rare species, also from Mr. Dodge a collection of 211 moths from Exeter, Vol. XIV] EVERMANN— DIRECTOR'S REPORT FOR ms 539 California, secured by his son, the late Ralph M. Dodge; from John E. Carey, 905 Lepidoptera from Panama including many rare and beautiful forms. Other valuable donations to the department collection were made by Mr. Louis Slevin, Mr. E. R. Leach, Mr. J. O. Martin, Mr. Geo. Haley, Dr. J. A. Comstock, Mr. David M. McKell, Mr. B. H. Murray, Mr. Eric Walther, Mr. Joseph Mailliard, Mrs. H. J. Smith, Mr. Frank Mason, Mr. J. G. Grundell, and others. In addition to these donations 3800 insects were secured by the curator and his assistant in field work in the Bay region. On January first, Mr. Hartford H. Keifer was added to the department staff as full-time assistant, and, through his continued and faithful efforts, much has been done toward mounting and labelling accumulated material. Mr. J. O. Martin completed the installation of the Holbrook collection of butterflies, which now is well displayed on specially constructed multiplex frames in the bird hall. Following the completion of the Holbrook col- lection, he has been working part time on the incorporation of the Van Dyke collection into that of the Academy in the new unit boxes recently adopted in this department. Over 26,000 specimens from the Van Dyke collection have been so arranged and the work is being pushed as rapidly as possible. The balance of the material taken on the Arizona expedition of 1924 has been mounted and, with the Holbrook collection, brings the total additions to this department for 1924 up to 30,700 specimens. The Academy is under renewed obligations to Messrs. Barnes and Benjamin for the determination of moths in its collection. Through this assistance most of the moths, exclusive of the micros, are now determined and the arranging of the collection will be pushed as rapidly as boxes be- come available. Prof. P. A. Qaassen of Cornell University has deter- mined the stone-flies in the collection and these are now available for study. Dr. E. C. Van Dyke has devoted much time and effort during the year to checking over the Academy collection of beetles as fast as they are arranged in the unit boxes. So far, the families Cerambycidae, Buprestidse, Scarabiidse, Cicindelidse and the Cychriini have been gone over by him and are now available for the use of students of these inter- esting insects. The Pan-Pacific Entomologist, initiated in 1924, has reached the middle of the second volume. This effort to give the West a place in the en-i tomological literature of the country is meeting with much encourage- ment. While it is not yet self-sustaining, that goal does not seem as distant as it did, and with moderate assistance for a few years it should attain independence and show growth both in size and quality. The growth of the Department of Entomology during recent years has been most encouraging and, with continued support, the Academy of Sciences will have a collection of insects that will rank among the largest and most valuable in the country. Edward P. Van Duzee, Curator. 540 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. Department of Exhibits So much of the time of the personnel of this department has been di- verted to other matters that there is less to report as accomplished in the field of exhibits than has been the case in previous years; but, in spite of interruptions, Mr. Frank Tose, chief taxidermist and group artist of the Museum, has arranged and installed four more panel groups in the Bird and Mammal halls, all of which have attracted much favorable comment. The four groups are : California Woodpecker, Lazuli Bunting, Point Reyes Mountain Beaver, and Warner Mountain Cony. The Cali- fornia Woodpecker Group is especially interesting in that it shows the combination of a nesting hole and a tree that is thickly inset with acorns, well exemplifying the characteristic storage habit of this bird. The Moun- tain Beaver and the Cony groups exhibit two species of small mammals so rarely seen by the public that the majority of people do not even know of their existence. The rearranging of the Grizzly Bear Group, which was commenced late in the fall of 1924, extended well into January, 1925. In the early spring a number of birds were collected and mounted in preparation for that time when the proposed seasonal groups of the birds of Golden Gate Park become realities. In between times some fine work was done on wax reproductions of beautiful Colorado Desert cacti, to be installed in the present desert group to make it even more attractive. A matter that occupied several weeks of departmental time was the construction and the placing in position for future use of cases for panel groups in all available spaces in order to save the time and labor involved by the old method of setting in position cases for each group as needed. The backs of these newly installed cases and the backs of all those al- ready arranged with groups have have been so treated as to make them harmonize with the backgrounds and accessories of the large habitat groups into which they project. The camouflaging of these projecting backs has greatly improved the appearance of the large groups and added to their charm. Mr. Tose was detailed, with Mr. J. T. Wright as assistant, to represent the departments of Ornithology and Mammalogy on the expedition that started about the middle of April to the Revillagigedo and Tres Marias islands and returned toward the end of June. The preparation of equip- ment before starting and the finishing up of the temporarily prepared and cold storage specimens obtained on this expedition, with the voyage itself, occupied these members of the department from the first of April until well into July. Later in the year, practically a month was occupied by Mr. Tose in making from a cast a life-sized model of a great Leatherback Turtle for the Department of Herpetology. Vol. XIV] EVERMANN— DIRECTOR'S REPORT FOR 1925 541 While the demand for portable school groups does not seem to have lessened, there has been no time available, with the present force, for the construction of new ones, and the only work carried on in this line has been the reconstruction of some that had been damaged by accidents. The portable school groups now in use consist of one each of the following: Sandpipers and marsh birds, California Woodpecker, Gila Woodpecker, Barn Owl, Western Meadowlark, California Shrike, San Francisco Towhee, Western Robin, Sierra Golden-mantled Ground Squirrel, Cali- fornia Ground Squirrel, Sierra Chickaree, Redwood Weasel, and Spiny Pocket Mouse. Student assistants in this department have been as follows : James F. Campbell, for the greater part of the year; Miss A. M, Hill, short course in accessory work; J. T. Wright, first half of year; Russel Hendricks and Cecil Tose, part time; and several school boys at various periods. Joseph Mailliard, Curator. Department of Fishes This Department was established August 29, 1925, at which time Mr. H. Walton Qark was made assistant curator. Mr. Clark had been a scientific assistant in the United States Bureau of Fisheries for many years, during wliich he was chiefly engaged in biological investigations relating to fishes and the fisheries and in studies of the geographic dis-^ tribution of fishes. When the Steinhart Aquarium was established in 1923 Mr. Clark was made chief collector, which position he held until transferred to his present position. The establishment of a department of fishes seemed necessary in order that proper attention might be given to systematic and life-history studies of the fishes of California and elsewhere in connection with the Aquarium and the Museum. Considerable collections of fishes have already been acquired, the principal regions represented being California, the Hawaiian Islands, China, and the Revillagigedo and Tres Marias islands oflf the Pacific coast of Mexico. These will all be studied, carefully identified and put in order as rapidly as possible. It is the intention to install in the Aquarium laboratories a carefully identified reference series of specimens in alcohol of all the species of fishes of California, both fresh and salt water, and, as time and oppor- tunity permit, similar series of the species found in the other Pacific coast states. Teachers, anglers and others often come to the Aquarium or the Museum and make inquiry about some fish they have seen but which they do not find in the Aquarium. It is hoped that when our reference series has been established, we shall be able to show to such inquirers a speci- men of any species of fish about which they ask. During the year Mr. Clark has devoted most of his time assisting Dr. Jordan and the Curator with the preparation of a revised check-list of 542 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. the fishes of North and Middle America, upon which they have been en- gaged for several years. He and the Curator also have in preparation a distributional check-list of the freshwater fishes of California which they hope to complete in the near future. They arc also engaged in preparing a report on the fishes of the Ortolan expedition of 1925 to the Revillagi- gedo, Tres Marias, and other islands off the Pacific Coast of Mexico. Barton Warren Evermann, Curator. Department of Herpetology At the beginning of the year 1925 the Academy's collection of reptiles and amphibians numbered 56,033 specimens. There have been added dur- ing the year 3,253 specimens, so that the collection has grown to 59,286 specimens. Gifts of specimens during the year have been received as follows : From Steinhart Aquarium, 3 specimens ; J. Labarthe, 1 ; Prof. W. B. Herms, Z7 ; Fred. Howarth, 11; Dr. E. C. Van Dyke, 15; H. W. Qark, 1; E. W. Williman, 3 ; Melbourne Ward, 5 ; L. M. Klauber, 145 ; and Miss M. E. McLellan, 8. Specimens have been secured from 5 counties of California as follows : Imperial, 4; Plumas, 6; San Diego, 136; San Francisco, 1; and San Mateo, 3. Specimens from other localities are: Nevada, 1; New York, 11; Ore- gon, 1; Virginia, 3; Washington, 11; Eastern Asia, 14; Africa, 14; Aus- tralia, 5 ; Fanning Island, 2>7 ; Alexico, 2997 ; Ecuador, 1 ; Peru, 6 ; and Costa Rica, 2. Work has been begun, and considerable progress made, on an account of the amphibians of the western portion of our continent, to complete the review of the herpetology begun by the late Dr. Van Denburgh. Mr. Frank Tose, of the Department of Exhibits, has completed the casting of the large leather-back turtle presented to the Academy by the San Francisco International Fish Company. The classification, labeling, cataloging, and arrangement of the collection was continued during the year. Field work was carried on in Mexico. The expedition to the Revillagi- gedo Islands resulted in a collection of 1,550 specimens, and the continua- tion of the field work in the states of Oaxaca, Vera Cruz, Tehauntepec, and the Federal District of Mexico in 1,438 specimens. The thanks of the department are due Profs. Herrera, Solis, and Contreras, of Mexico City, and Mr. Paul Ruthling, of Cosolapa, for the many courtesies extended. Joseph R. Slevin, Assistant Curator. Vol. XIV] EVERM ANN— DIRECTOR'S REPORT FOR ii>i3 543 Library During the year 1925 the library of the Academy maintained a steady and satisfactory growth in all departments of its work. The accessions numbered 967 complete volumes, of which 336 were added by purchase, 239 by gift, and 492 by the completion of volumes through material re- ceived in exchange. In addition to these the usual number of serial publications were received by exchange. Most of these exchanges were publications of scientific societies and will be included in completed volumes later. A number of valuable donations to the library were re- ceived during the year, but none of exceptional extent, although among them were a few that made most welcome additions to the library re- sources of the Academy. Miss Margaret Dold severed her connection with the library on May 25, and for some time the library was without an attendant. On Septem- ber first Mr. C A. Bellas entered upon the duties of assistant in the library and, by faithful work, has gotten the the accumulated material assorted and properly shelved. He has also entered on the accessions register all complete volumes received and has classified and catalogued certain books requiring such attention. He has also done much toward bringing up to date certain of the foreign exchanges that had gotten be- hind during the war conditions. Another item of much interest in the library work was the binding of 1183 volumes. For a number of years no binding had been done, so there was a large accumulation of unbound material. Such unbound volumes are awkward to handle and are subject to rapid deterioration in use, so the binding of so many volumes was an improvement in the li- brary service that has been very much appreciated by the library staff. A minor convenience to all users of the library was the construction of a small case near a window for shelving the Zoological Record, so those most indispensable helps can now be referred to without the inconveni- ence of stack use. On the whole, the library has made a most satisfactory growth in its resources and in its use both by the staff and by outside members, and the outlook for the coming year is most encouraging. Edward P. Van Duzee, Assistant Librarian. Department of Mammalogy As has been customary for the past few years, work in this department has been carried on in connection with that of the Department of Orni- thology, and there has been but little attempted that was particularly dis-' tinctive. Limited collections of the smaller mammals have been made by the Curator and his assistants in Modoc, Siskiyou, and Placer counties, Cali- fornia, and in the extreme southern part of Josephine County, Oregon ; 544 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. by Mr. Frank Tose, of the Department of Exhibits, and his assistant, Mr. J. T. Wright, at various points visited by the Revillagigedo and Tres Marias Expedition ; and by Miss M. E. McLellan, Assistant Curator of the Department of Ornithology, in the provinces of Sinaloa and Nayarit, Mexico. Through the courtesy of the CaHfornia Sea Products Company, Dr. E. T. Engle, who had placed his services for a limited period at the dis- posal of the Academy, obtained at the Trinidad Whaling Station, Hum- boldt County, California, some valuable osteological specimens of Cetacea and some interesting data, for this department. The principal features of the indoor work of the department in the past year have been the construction of a new hide room and the installa- tion in it of the collection of hides of marine mammals ; the transfer of the skins of the smaller mammals from the large hide room to the stand- ard metal cases in the mammal room, wherein several new cases have been placed; the tanning of what hides were still awaiting treatment and the rearrangement of the osteological collection. Accessions to this department have been as follows : By exploration: 127 specimens. By gift: C. W. Bowman, 3; California State Bureau of Animal Industry, 1 ; Mrs. F. Ellsworth, 1 ; Russel Hendricks, 1 ; E. R. Leach, 1 ; A. K. Macomber, 1 ; John McLaren, 3 ; W. M. Phillips, 1 ; Stein- hart Aquarium, 1; Mrs. Peter Swartz, 1; E. P. Van Duzee, 2; J. T. Wright, 4. By purchase: 2 speciments. Joseph Mailliard, Curator. Department of Ornithology Early in the year the Mailliard oological and ornithological collections (with the exception of a small portion temporarily reserved, consisting of a minimum representation of all species of birds and eggs included in it) were transferred from the residence of Mr. John W. Mailliard to the Museum of the California Academy of Sciences and installed there, for the time being as separate imits. This addition to the collections, together with the John Van Denburgh collection of eggs (received in 1924, through Mr. Douglas Van Denburgh), which has been properly boxed and made ready for incorporation in the collections, and the increase in the number of specimens through field work, necessitating the installation of eleven new cases, has resulted in the filling of all the space available in the three rooms allotted to the de- partment. Within a short time, provision will have to be made whereby the department may have additional room to house the rapidly growing collections. The addition of the new cases made necessary a rearrangement of the whole collection. This work has been carried on by Assistant Curator M. E. McLellan, as time could be spared from other duties, but it is not yet completed. Vol. XIV] E]ERMANN— DIRECTOR'S REPORT FOR 1925 545 In the absence of a regular librarian, Miss McLellan, being familiar with the work, devoted time for the space of three months to library affairs needing immediate attention, which, in consequence, curtailed the amount of work that could be accomplished in this department. Expeditions and field work occupied a considerable portion of the year. In cooperation with the other departments of the Museum, this depart- ment participated in the Academy's expedition to the Revillagigedo and Tres Marias islands off the Mexican coast, as mentioned in the annual report of the President of the Academy. On this occasion the depart- ments of Ornithology and Mammalogy were represented by Mr. Frank Tose, chief taxidermist of the Museum, and Mr. J. T. Wright, student and part-time assistant in the Department of Exhibits. A good collection of birds was made and some especially interesting material was obtained on this expedition. In Siskiyou County, California, the valley of the Klamath River, from the vicinity of Hornbrook to Happy Camp and Indian Creek, some 50 miles west of Hornbrook, together with parts of Josephine County, Ore-" gon, adjacent to the California line, was the scene of field activities from May 9 to June 13, the field party consisting of the curator, James F. Campbell, student assistant, and Raleigh Borell, general assistant. Field work was also carried on by the Curator and Raleigh Borell in Placer County, California, from June 28 to July 10. With John Denver as general assistant, the Curator carried on field work at Eagleville, Modoc County, California, from September 8 to Octo- ber 15, for the purpose of comparing the bird life found there in a normal autumn season like that of 1925 with that found in the previous year, which was the third and worst year of a prolonged drouth. One of the principal features of the work in 1925 at Eagleville was the trapping and banding of nearly 400 Gambel's Sparrows on their southward migration. This was done in the hope that some of the birds might fall into the hands of other bird banders or of people along the line of flight who might be sufficiently interested to send the band, if taken from a dead bird, or to report the band number, if found on a captured bird, to the U. S. Bio- logical Survey, Washington, D. C, and thus add to our rather limited knowledge of the migratory movements of birds. The last two weeks of December were occupied by the Curator, with Raleigh Borell as assistant, in investigating the winter bird life in parts of Placer County, California, and in doing some further work in bird banding. On September 5, Miss McLellan started upon a trip to the states of Sinaloa and Nayarit, Mexico, for the purpose of securing specimens of birds from the mainland for comparison with those obtained on the Tres Marias by the departmental representatives in the spring. Work was be- gun about the middle of September and carried on for a period of six weeks at Labrados (near Mazatlan), San Bias, and Maria Madre Island. 546 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. The results of this trip were very satisfactory, not only because of the number of specimens secured, but also on account of the comparatively large number of species represented among them, and the obtaining on Maria Madre of representatives of several species not previously recorded from the Tres Marias. During the year the library of this department has obtained certain valuable works, notably, Gray's Genera of Birds, Stray Feathers, Latham's General Synopsis of Birds, and Rowley's Ornithological Miscellany, and provision has been made for still further additions. In the latter part of the year the purchase of a suitable automobile for the joint use of the departments of Ornithology and Paleontology was decided upon, as these departments can so coordinate their field work as not to interfere seriously with each other in regard to the date and period of use. Accessions to the department have been as follows : Bird skins — By exploration: 1373 specimens. By gift: E. W. Gifford, 1; E. C. Johnson, 1 ; G. L. Merguire, 1; Nick Mouzin (for Charles White), 1 ; J. W. Stein- beck, 3; J. T. Wright, 94. By purchase: 6 specimens. Birds' nests and eggs have been received as follows : By exploration : 59 sets (78 eggs). By gift: E. W. Gifford, 1 egg; Mrs. Lloyd H. Robbins, 1 nest. Joseph Mailliard, Curator. Department of Paleontology During 1925 several considerable and noteworthy collections came to the Department of Paleontology. Dr. Roy E. Dickerson, formerly Curator, presented a large collection of invertebrate fossils from the Philippine Islands, Java and Japan. After several months of exploration in the bone beds of Shark-Tooth Hill, Kern County, California, under the direction of Charles Morrice, work there was suspended early in the year. The material collected was transmitted to Dr. Remington Kellogg, U. S. Biological Survey, Washing- ton, D. C, for study and report, and, although a great many valuable additions to vertebrate paleontology have been made at that locality, it seems probable that a better site for a quarry may be found in the vicinity. In the excavations thus far explored the bones of the animals are scat- tered and broken although they are present in almost unbelievable abundance. In April, the Curator and Assistant Curator left San Francisco on the U. S. S. Ortolan, as members of the Revillagigedo Islands Expedition. Almost two months were spent in the field. Collections were made of fishes, marine invertebrates, fossils, rocks, and living marine and land mollusks. Formal reports will be prepared on these various groups and they will give a better indication of the character of the collections than a preliminary announcement. However, it should be explained at this Vol. XIV] EVERMANN— DIRECTOR'S REPORT FOR 1925 547 point that the giving of figures to represent numbers of specimens in this department is impracticable. For instance, a single cubic inch of some of the samples of organic shales collected can be shown to contain more than a hundred million individual skeletons of organisms. One other accession worthy of note is the large collection of samples of sedimentary rocks and shales obtained in drilling oil wells by the Pacific and Associated Oil Companies. It is impossible to estimate the scientific value of this collection and it is the only one of its kind of any consequence in existence in any museum. It would cost many millions of dollars in drilling expense to duplicate the collection. On account of lack of storage space in the laboratory and the large size of this collection, it has been necessary to house it in the basement of the Museum building, but there it has been systematically arranged so that any part is readily accessible. The bulk of the detailed work of the Department during this year has fallen upon Mr. Eric Knight Jordan, Assistant Curator, and Mr. Leo G. Hertlein, Temporary Assistant. Their duties have been faithfully and efficiently performed, and this is reflected in the fact that the collections of the Department have probably never before been so well kept or so orderly arranged. Various institutions and individuals have made use of the collections of the Department and at the end of the year the outstanding loans were as follows: Dr. Paul Bartsch, U. S. National Museum, Washington, D. C. ; Miss Mary J. Rathbun, U. S. National Museum, Washington, D. C. ; Dr. V/. P. Woodring (Feb. 12, 1926), U. S. Geological Survey, Washington, D. C; Dr. Wm. H. Dall, U. S. National Museum, Washington, D. C; Dr. Fred Baker, Point Loma, California. G. Dallas Hanna, Curator. Steinhart Aquarium It is a pleasure to report the Aquarium in good condition and the most popular public institution in San Francisco. The attendance for the year was 1,043,591. Our attendance on Sundays and holidays is still too large for seeing the fishes to the best advantage and is a constantly repeated argument for additional room that a new wing would provide. The total number of live specimens in the Aquarium tanks on Dec. 31, 1925, was 7,120, an increase of 912 during the year. These are di- vided among the branches of the animal kingdom as follows : Mammals 8 specimens 4 species Birds 1 specimen 1 species Reptiles 75 specimens 22 species Batrachians 13 specimens 7 species Fishes 6596 specimens 201 species Invertebrates 427 specimens 6 species Total 7120 specimens 240 species 548 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. The above is exclusive of the Hatchery in which 8,000 eggs of Trout and Salmon were hatched during the year. It would seem a far cry from the slimy Hagfish in tank No. 9 to the study of Pyorrhea. However, one of the activities of the Aquarium during the past year was to supply quantities of mucous from these fish to Dr. R. N. Loomis of the University of California Dental College in order that the effects of mucous on dentin might be carefully studied and its relation to disease, if any, established. One would not really suspect the Aquarium to have any connection whatever with the 18th amendment, yet a special investigator, Dr. McCay of the California State Fish and Game Commission, spent a month in our Laboratory investigating the pollution of the San Francisco Bay water by a large distillery and the effect of the same on our commercial fishes. Dr. Shaw, of Shanghai, China, and Dr. Deogracis Villadolid, from the Philippine Islands, have spent considerable time on the study of our collections. The State Board of Health of Sacramento keeps one of our large tanks well stocked with mosquito fish (Gambusia affinis), and has re- quested us to distribute these fishes free of charge to anyone desiring small fish for stocking ponds, garden pools and aquariums. Several hun- dred of these have been so distributed and will no doubt assist in the abatement of the mosquito pest in this state. On Nov. 2, 1925, a shipment of these fish was sent to Tahiti, Society Islands, to help to eliminate the mosquitos. The gifts of live animals to the Aquarium during the year number 726. Eight of these were alligators. Our loss of specimens during the year has not been excessive. We have had no bad epidemics ; as a matter of fact, we have been assured on very good authority, our loss has been considerably less than at other large aquariums. We have been fortunate in securing the services of Mr. Robert J. Lanier, formerly of the New York Aquarium, whose long experience in that aquarium wil be of benefit to us. Mr, H. Walton Clark was transferred from the Aquarium staff on Sept. 14 to the position of Assistant Curator of fishes in the California Acad- emy of Sciences. On March 20, our collector, W. J. Martin, resigned and his place was taken by Mr. Herbert Brandt. With the exceptions noted above and a few minor changes, the staff of the Aquarium remains the same. It is the desire of the Superintendent that the Aquarium may continue to improve during the coming year. As a means to that end we respect- fully suggest that a small greenhouse for growing of tropical plants and fishes be constructed on the roof of the Aquarium, and the matter of securing more warm water tanks seriously be considered. Also that ar- rangements be made to secure a large number of the beautifully colored fishes found along the shores of Mexico and Central America. Vol. XIV] EVERMANN— DIRECTOR'S REPORT FOR 1925 549 During the year, 728 gifts of living animals, chiefly fishes and reptiles, were made to the Aquarium. To the many donors our grateful appreci- ation is hereby expressed. During the same period the Academy, on behalf of the Aquarium, sup- plied a total of 1858 specimens of live fishes and other small aquatic ani- mals to schools and individuals for use in small balanced aquariums in schools and homes. In this way and through definite instruction we are doing much to encourage the establishment and maintenance of these really educative adjuncts to schools and homes. The number of schools visiting the Aquarium continues to grow, as shown by the following summary : SCHOOLS \TSITING THE AQUARIUM Schools of San Francisco Total Number Visiting Pupils 8090 8090 Total Number Visiting Teachers 285 Total Number Visiting Classes 299 Schools Outside of San Francisco Total Number of Pupils 1776 1776 Total Number of Teachers 65 Total Number of Classes 83 9866 Alvin Seale, Superintendent.
