INTRODUCTION. The fishes which form the basis for the present report were collected from the following localities: — Acapulco, Mexico; Perico, Naos, and Toboguilla islands in Panama Bay; the shores and markets of Panama City; the Galapagos Islands (principally at Wreck Bay, Chatham Island); in Cook and La Perouse bays and along shores of Easter Island; Manga Reva (principally in Port Rikitea and on the outer reef) ; and from dredge hauls taken along the coast of southern California, Mexico, Central America, Peru, and the open seas en route to the above mentioned island groups which yielded a few pelagic forms. As would be expected from places so widely separated the faunas are more or less distinct. An examination of the list of species as represented by the collection reveals the following points: — - 1. The fauna of the Galapagos is quite similar to that of Mexico and Central America. 2. The fauna of Easter Island (represented by twenty-two species not taken at any other point visited) seems to be different from that of its nearest neighbor, Manga Reva (Paumotus) and appears closest to that of Norfolk Island. 3. With one exception (Mapo soporator) none of the forty-two species from Manga Reva was taken at any other point visited. Its fauna is naturally similar to that of the other islands of the Paumotu Archipelago. Unless otherwise stated, proportional measurements of length of head and depth of body are expressed in terms of length without the caudal, and the others in terms of length of head measured from tip of snout to posterior edge of opercle. In the scale counts in longitudinal series, the total number of trans- verse rows above the lateral line has been counted and only the fully developed scales at the base of the caudal included. 78 THE SHORE FISHES. In this collection there are representatives of fifty-five families and two hundred and twenty-seven species, of which the following are described as new: — Raja aguja, Kuhlia nutabunda, Girella nebulosa, Eques fuscovittatus, Gillelus rubellulus, and Enneapterygius corallicola. The description of a new blenny, Alticus margaritatus from Pago Pago, Samoa is also included in the present report. Specimens representing one hundred and fifty species have been sent to the Museum of Comparative Zoology, all others including the types of the new species, to the U. S. National Museum. The illustrations are from drawings by Miss Violet Dandridge. RAJIDAE. Raja aguja, sp. no v. Plate 1, figs. 1-2. Type, No. 65641, U. S. N. M.

Z. 29663, 15, 3201, M. C. Z. 29640, 17 inches long from Cook Bay, Easter Island. Teeth in No. 3170 are in a single series on sides of both jaws; same on vomer; in front of this row on vomer is a single long fang-like tooth, there being quite a space between the tooth and the end of the row; eye 2.5 in snout; snout 2 in gape. General color dark brown; the entire specimen thickly covered with small yellow spots interspersed with larger black ones, giving it a speckled appearance; anal with a narrow margin of yellow; dorsal margin yellow only where the spots touch the margin. In No. 3171 the teeth are biserial on the sides of upper jaw, and uniserial in lower jaw; anteriorly in the upper jaw there are two transverse rows of three fang-like teeth each; eye 1.83 in snout; snout 2.36 in gape. General color similar to above, except posteriorly. The spots on body and fins are somewhat larger; no distinct pale margins to the fins; on the belly the yellow spots are finer and more or less coalescent, giving a rivulated appearance. In 3200, M. C. Z. 29663, the teeth are similar to those in No. 3171; eye 2 in snout; snout 2.22 in gape. Coloration similar to No. 3171, except that the spots are distinct on the belly and do not give the rivulated appearances; on the fins, the spots are a POECILIIDAE. 83 little more regularly rounded; the larger of the black spots are a little more than half the size of eye. In No. 3201, M. C. Z. 29640, the teeth are exactly as in the last specimen; eye 2.09 in snout; snout 2.17 in gape. General color, dark chocolate brown, thickly covered with small pale spots anteriorly, and sparsely posteriorly; numerous black spots, many as large as eye on body, arranged in more or less regular transverse rows at least anteriorly.

A specimen, No. 3377, 16 inches long from Acapulco. Descriptions of this species state that it has no posterior nasal rim or tube. The specimen studied, however, has a prominent posterior nasal tube. All the specimens entering into these descriptions were small and the length of the tube in specimens of Uropterygius and "Scuticaria" seem to vary with the size or age of the individual. The present specimen is in poor condition, is strongly com- pressed laterally, fins showing only on the end of tail and confluent around it, the dorsal extending about twice as far forward as the anal; eye 2.28 in the snout; snout 2.62 in gape; teeth in two series on the sides of upper jaw meeting at the symphysis, the outermost numerous and much smaller, inner long and sharp; behind the inner row of teeth in front are two cross-rows of four each, very long sharp teeth; mandible with two rows of teeth similar to those in upper jaw, but the long sharp teeth are bunched and not in rows.

In the key to the genera of Serranidae Jordan and Evermann (loc. cit., p. 1129-1130) place Prionodes in a group said to have no depressible teeth; in the generic description it is stated that "there are no depressible teeth in jaws." In our specimens some of the posterior premaxillary teeth and some of the lateral mandibular teeth are depressible. The prominence of the lower jaw varies somewhat; the caudal is slightly emarginate or truncate, and the upper rays somewhat produced, the prolongation varying somewhat in length.

Three specimens ll, In and 2Tg inches long from Toboguilla Island, Panama Bay, collected among coral at depth of two fathoms. M. C. Z. 29409 (1 speci- men) . The larger specimen has head 2.75 in length; depth 3.66; eye 4 in head; snout 5.33; maxillary 1.77; D. VII, 22; A. Ill, 18; scales above lateral line in longitudinal series 50 + , from origin of spinous dorsal downward and backward to lateral line 4?; from lateral line downward and backward to origin of anal 21. In the largest and the smallest specimens, the anterior nasal tube and the supraorbital flap are comparatively small, but in the intermediate specimen these are considerably larger. In the largest specimen the general color is brown; throat, maxillary, cheek, lower opercle, and breast paler; a faint dusky blotch just behind lower part of eye; a large well-defined dark brown spot on upper part of opercle; body clouded with dark brown, with traces of longitudinal dusky lines along each row of scales; pectorals and ventrals dark gray; dorsal, anal, and caudal blue black, with narrow pale margins. The other two specimens are essentially the same color as above, except that the smallest specimen is somewhat lighter than the other two. LOBOTIDAE. Lobotes pacificus Gilbert. Bull. 47, U. S. Nat.

Six specimens 5t5 to 5il inches long from Manga Reva, coral. M. C. Z. 29411 (3 specimens). The following life color note was found with the specimens: — "Lower parts bright red, fading to silvery; upper, greenish blue, becoming purple in formalin." Opercle and subopercle are scaly; in other respects our specimens agree with Steindachner's description of C. muUiradiatus (Verh. Zool. Bot. Gesellsch. Wien, 1861, 11, p. 175, fig. 1). Gunther, (loc. cit.) places C. muUiradiatus in synonymy of C. tile, giving the range of soft dorsal rays as 17-21; while our specimens do not show the same range (being 20-22), we assume that Gunther had more material and therefore accept his identification.

IQTHOSIDAE. 119 Three specimens, Nos. 3148-49-50, 9j, Si and lOg inches long from Tobo- guilla Island, Panama Bay. M. C. Z. 29617 (1 specimen). The specimens from Acapulco differ somewhat from those from Toboguilla Island, which are here provisionally identified with those from Acapulco. The Acapulco specimens from geographical considerations should be most like typical K. elegans, which came from Mazatlan, but they differ from the description given by Jordan and Evermann (loc. cit.), in having 12 anal rays instead of 11, larger eye, longer snout and maxillary, and somewhat longer pectoral ; and also in having 13 dorsal rays instead of 12. Gilbert and Starks {loc. cit.), in their remarks on specimens they have identified as K. elegans, call attention to this difference in the fin rays. The Acapulco specimens differ also from those from Toboguilla in having a somewhat shorter head, smaller eye, slightly shorter maxillary, and a longer anal base. In the Toboguilla specimens the snout is somewhat more vertical, the forehead is a little more prominent and the throat somewhat concave in outline, which in the Acapulco specimens is nearly in line with the ventral curve.

Two speci- mens 2? and 3n inches long from the same place. 122 THE SHORE FISHES. Six specimens I to Is inches long from shore of Easter Island, December 20, 1904. General color, iridescent gray with nine purplish brown cross-bands, wider above, tapering toward ventral surface, these about .5 diameter of eye at top; interspaces thickly spotted with brown, many of these coalescing into irregular shaped areas; two longitudinal rows of comparatively large spots on inter- spinous membranes of dorsal, the first through middle of fin, the second near base; three or four rows of smaller spots on basal half of soft dorsal and anal; a few small faint spots on basal portion of caudal; pectoral pale; ventral dusky; outer margin of vertical fins dusky; teeth trilobate. The stomach is gizzard-like, peritoneum black, underlaid with silvery; owing to the bad condition of the viscera the pyloric coeca are difficult to count but there are probably not over twenty; air bladder divided into two horns posteriorly; in one of the specimens examined the stomach and intestines were filled largely with a calcareous Alga (Corallina); a few diatoms, other algae and small gastropods were also present. These specimens apparently differ from current descriptions of Girella and Tephraeops in lacking an inner band of smaller teeth on jaws and in having in the largest specimen (type) a number of smaller supernumerary teeth outside of and closely attached to the regular series.

Pomacentrus rectifraenum Gill. Proc. Acad. Nat. Sci. Phil., 1862, p. 148. Gilbert & St.4.rks, Mem. Cal. Acad. Sci., 1904, 4, p. 140. Gilbert and Starks {loc. cit.) state that in this species there are constantly 15 soft dorsal rays and 13 anal rays, the last split ray being in each case, reckoned as one. They also state that in Gill's description of the types of P. rectifraenum, he assigns to it 16 dorsal rays and 15 anal rays and it is reasonable to suppose that the split ray at the end of each fin was, by him, reckoned as two rays. In our description, we have followed the latter plan. Four large specimens, 41 to 5| inches long from Acapulco. Nine large specimens, 3? to 64 inches long from Toboguilla Island, among rocks in two fathoms of water. M. C. Z. 29448 (2 specimens). The Acapulco specimens have uniformly 16 dorsal rays and 14 anal rays. Five of the Toboguilla specimens have 16 dorsal rays and four have 15 dorsal rays; six have 14 anal rays and three have 15 anal rays. The above specimens show the following colors : — General color dark brown, darker on top of head, lighter on breast and belly; margin of upper lip and whole of lower lip pale; the scales of sides of body have dark-margins, forming transverse lines; dorsal, ventral, anal, and caudal blue-black; pectoral with dusky rays, paler membranes forming a dark olive shade, the two upper rays are paler, base of pectoral brown body color with a small black spot at base of 1st ray, a white bar, widest at the top, extending across base of the rays behind, this bar sharply separating the dusky pectoral from its brown base. These specimens show no traces of pearly spots. Nine specimens 2s to 3^ inches long from Perico Island, Panama Bay. POMACENTRIDAE. 127 Of those, eight have Ki dorsal rays and one has 17 dorsal rays; the anals have uniformly 14 rays. These specimens show the following colors: — all more or less spotted with pale blue or pearly spots ; the three larger ones with no spots on body and fewer and fainter spots on head and fins; some of the smaller specimens similarly marked ; the posterior margins of body scales dusky, forming narrow transverse lines; in some of the smaller specimens, in addition to the dusky marks there is a pale blue curved bar on each scale on side of body becoming spots on back and belly and forming alternating transverse lines with the darker margins below lateral line and long lines following rows of scales above lateral line; the spots on the side of the head are irregular in size and arranged approximately in series downward and forward towards the isthmus: two lines formed of these spots under the eye, one just below suborbital following its curve to corner of mouth, one under eye and parallel with its margin on the suborbital, a short line extends from front of eye forward to edge of preorbital; a light blue line on upper part of eye; a line of coalescent spots extending from tip of snout back over eye to front of spinous dorsal, a series of fainter spots between these on the median line, such spots occurring also on soft dorsal and anal and 'following the row of scales ; in the smaller specimens a small black spot on caudal peduncle just back of the angle of soft dorsal; several specimens with a large pearly spot on angle of dorsal and anal; none of these showing traces of black spot or ocellus on anterior base of soft dorsal; a small black spot on upper base of first ray of pectoral. In these specimens the pectoral fins are pale, agreeing with the larger specimens in the markings behind pectoral. Three specimens if to 2 inches long from Perico Island, Panama Bay. These specimens are like the preceding except that they show traces of the black spot on anterior base of soft dorsal. Two specimens 2\ to Si inches long from Toboguilla Island, Panama Bay, among coral in two fathoms of water. These have 16 dorsal and 14 anal rays. They are similar in color to the larger specimens but show a few pearly spots on sides of head. Seven specimens Is to 2i6 inches long from Acapulco. M. C. Z. 29568 (4 specimens). Of these, all have 16 dorsal rays; six have 14 anal rays and one has 13 anal rays. These specimens have the general color of the Perico Island specimens, but the three largest show traces of a black spot on the anterior base of soft dorsal; 128 THE SHORE FISHES. the smaller ones show distinct black spots on anterior base, each surrounded by pearly spots giving the appearance of an ocellus. Ponaacentrus gilli Gilbert & Starks. Mem. Cal. Acad. Sci., 1904, 4, p. 141, pi. 22, fig. 44. Three specimens 2s to 4| inches long from Acapulco. All have dorsal rays 15, one has anal rays 14, and two have them 13. Five specimens M. C. Z. 29567, 21 to 41 inches long from Perico Island. All have dorsal rays 15, and anal 13. Six specimens 2? to 3| inches long from Toboguilla Island, among coral in two fathoms of water. Of these five have dorsal rays 15, and six have anal 13, one has dorsal 16. One specimen, M. C. Z. 29453, 2? inches long from Perico Island. This has 15 dorsal rays and anal 13. The three specimens from Acapulco have general color brown, the posterior edges of scales darker, forming transverse lines on sides of body ; faint pale spots on sides of head, none on front of head or nape, both lips pale; no blue line on top of eye; a few pale spots on soft dorsal, anal, and caudal; pectoral very pale and translucent with no distinct spot at base of upper ray, base darker than body color both in front and behind; no di.stinct white bar on base of pectoral rays behind; in the two larger specimens no trace of spot or ocellus on anterior base of soft dorsal ; a large black spot on anterior base of soft dorsal in smallest specimen; in the two larger specimens the posterior margin of soft dorsal and anal paler; in smaller .specimen, posterior margins of these fins abruptly pale; a small black spot on upper base of caudal peduncle. The five specimens from Perico Island are similar in color to the above but slightly paler; the spots on head more distinct; none show pale spots on rays of soft dorsal, anal, or caudal; all have some pale spots on scaly base of anal; the two larger specimens show very slight traces of paler posterior margins to dorsals and anals. On the two next in size this is more distinct and on the smallest it is abruptly paler, none showing traces of spot or ocellus on soft dorsal, or spot on top of caudal peduncle. The largest one shows no white spot on axil of dorsal or anal. The next in size has a spot on base of posterior rays of anal, the others having these in axil of both fins, that of anal extending on to rays. The six specimens from Toboguilla are similar in color, all but one darker than the preceding; spots on head very distinct; the smallest is pale with distinct spot at base of first pectoral ray; outer margin of vertical fins dusky POMACENTRIDAE. 129 with a faint inner pale band; traces of pearly spots on scaled base of anal and on belly and posterior part of body, but none of these spots are present in the larger specimens. The one specimen from Perico Island is similar in color to the paler forms above described; spots on side of head distinct; no spot on caudal peduncle; fins same color as body; pale spot in axil of dorsal and anal. Comparative Measurements. Pomacentrus rectifTaenum Pomacentrus gilli. Total length 94 mm. 94 mm.

In the specimens which we have identified as these two species we find that all the above characters do not hold. In many of the smaller specimens of P. redifraenum, the pectorals are translucent; the eye is not constantly larger in P. gilli; the interorbital space agrees in being narrower in P. gilli, but the differ- ence in flatness in the two can not always be distinguished; while in the larger specimens the preorbital is somewhat narrower in P. gilli. This character is hard to distinguish in the small specimens and the preorbital serrations are variable and are of no importance as a means of separating the two species. Out of thirty-four specimens of P. redifraenum we have one specimen in which there are 13 rays in the anal; out of fifteen specimens of P. gilli we have one with 16 dorsal rays and one with 14 anal rays. These are probably individual variations and in general would not effect the separation of the species, since this variation does not affect both dorsal and anal in the same specimen. In our specimens, the presence of accessory scales upon the top of head and between eyes in P. redifraenum and their absence in P. gilli seems to furnish a distin- guishing character, particularly in the larger individuals. Another constant and well-marked character in P. redifraenum is the presence of a very distinct 130 THE SHORE FISHES. white bar on the base of the pectoral rays behind, separating the darker fin from the purphsh brown pectoral base. In practically all our specimens of P. recti- fraenum there is a small black spot on the outer base of the first pectoral ray which does not extend on to base of pectoral. On P. gilli there is no distinct black spot but a very dusky area extends across the outer base of the pectoral fin. Pomacentrus arcifrons Heller & Snodgrass. Proc. Wash. Acad.

The smaller specimen is similarly colored, the pale areas being, however, more marked; an indistinct ocellus is formed on the anterior base of soft dorsal by a circle of small pale spots, the ground color of the ocellus of same intensity as surrounding area. Thirteen specimens I to Ij inches long, Chatham Island. M. C. Z. 29456 (2 specimens), M. C. Z. 29606 (1 specimen). The general color of these is same as preceding, but the posterior pale area is almost yellowish white and covers posterior half of soft dorsal. The black ocellus on anterior base of soft dorsal is very distinct. The large specimens compared in color with specimens of P. rectifraenum of same size, show no marked difference. Our specimens of P. rectifraenum do not show the paler caudal peduncle and caudal. The specimens of P. arcifrons POMACENTRIDAE. 131 are a little more slender and the suborbital a little narrower. It is possible that the strong color marking of the very young of P. arcifrons may serve to distinguish them from young of P. rectifraenum. We have no very young of the latter. In as much as the posterior paler color decreases with age, it is probable that this character would not distinguish larger individuals from P. rectifraenum.

Color in spirits, top and sides of head to near lower edge of eye and extend- ing backward slightly below lateral line to under 6th or 7th dorsal ray abruptly purplish brown; below this, sides of head and body yellow, posteriorly brighter. The better preserved specimens have centres of scales, on sides of body on the purplish area and some on the head pale blue; posterior margin of scales dusky, forming narrow transverse lines becoming fainter posteriorly and ventrally; a jet black spot, sometimes ocellated, on upper .surface of caudal peduncle; small blue spots on scales of the dusky spinous dorsal; a trace of an inframarginal pale band also present on spinous dorsal ; soft dorsal dusky, with a white area, varying in size, on its posterior base, a large jet black-blue margined spot on 132 THE SHORE FISHES. anterior base of fin; in some specimens there are from one to three dusky spots near the base of the rays on the white area of the soft dorsal, there is a pale blue centre in some of these spots; pectoral pale and translucent with a small black spot on base of upper ray; ventral dark gray or slate; anal usually creamy white with a broad dusky anterior and lower margin, the posterior rays with dusky tips. Some specimens have dusky punctulations and numerous dusky spots on scales of anal, some of the spots have pale blue centres. Other speci- mens have larger spots posteriorly, similar to those on white area of soft dorsal; in some there are similar spots, varying in number and extent, on caudal ped- uncle and caudal; caudal fin dusky, varying in intensity. The head in P. flavilatua is closer to P. gilli than to P. redifraenum , but it is generally longer than in P. gilli and in the latter it is longer than in P. redi- fraenum. The three agree quite closely in depth, P. flavilalus averaging a little deeper. In the eye they overlap, but P. redifraenum averages a larger eye than P. flavilatus and it in turn averages larger than P. gilli. The pre- orbital in P. flavilatus is close to P. gilli, but is slightly narrower; in P. redi- fraenum it is considerably wider. The interorbital of P. flavilatus and P. gilli averages about the same; in P. redifraenum it is considerably wider. Except the great differences in coloration, there seem to be no characters by which we can distinguish P. flavilatus from the young of P. gilli. Our speci- mens of P. gilli, however, show a more vertical posterior margin to the pre- opercle, which in P. flavilatus is strongly inclined forward; P. redifraenum is quite distinct.

M. C. Z. 29442 (9 specimens). In counting the soft dorsal of the above specimens, we have counted the last ray divided to the base as two rays. It is evident that previous authors have counted as half or part of a ray what we now count as a ray. Out of thirty specimens counted from Easter Island, one had 16 dorsal rays, seventeen had 17 rays, eleven had 18 rays, and one had 19; the anal was uniformly 14; in the descriptions the dorsal has 16 and anal 13; specimens from Hawaii in POIVIACENTRIDAE. 133 the Jordan and Evermann colloction, seven specimens have dorsal 17, anal 14 as we count them. The very young have a small white margin on spinous dorsal, becoming progressively but variously narrower in specimens up to three inches long, after which it seems to disappear entirely. This margin is not so evident in the Hawaiian specimens of similar size. This may be due to their faded condition. Pomacentrus leucorus Gilbert. Proc. U. S. Nat. Mus. 1892, 14, p. 554.

In the larger specimen the black saddle on caudal peduncle is very indis- tinct, and the dorsal, caudal, and anal have very dusky edges, differing in this respect from the smaller one and the young. 134 THE SHORE FISHES. Twenty-one specimens I fo Ih inches long from Manga Reva. In these specimens the 2nd and 3rd body bands fuse on the spinous dorsal, in a distinct black area or blotch. The following color note was found with these specimens: — "Broad bars, light slate gray, light silver; dorsal and peduncle spots black; spinous dorsal canary behind spot." Six specimens Si to 7n inches long, No. 3282-85, No. 3285, M. C. Z. 29694- 95 (two damaged and not tagged), from Rikitea, Manga Reva. Abudefduf semptemfasciatus (Cuvier & Valenciennes). Jordan & Seale, Bull. U. S. Bur. Fish., 1908, 25, p. 285. Glyphisodon seplemfasciatus Cuv. & Val., Hist. Nat. Poiss. 1830, 5, p. 346 (463). Two specimens 51 and 7 inches long, 3286-7, M. C. Z. 29645, 29634 from Rikitea, Manga Reva. These specimens, which we provisionally identify as above, closely resemble our specimens of A. declivifrons, but have a somewhat narrower preorbital, a wider interorbital, and more dorsal and anal rays. They differ also in having paler fins; in A. declivifrons the soft dorsal, anal, and caudal are almost black while in A. septemfasciatus these fins are much paler with the tips of the dorsal lobes dusky and a broad sharply defined caudal terminal margin, widest at the end of the lobes. They do not agree in form with Bleeker's figure (Atlas 9, tab. 409, Pomac. tab. 10, fig. 5) of this species. Compared with a specimen 7? inches long from Samoa identified by Jordan and Seale as A. septemfasciatus, their specimen has a steeper profile and much darker coloration, and the ventrals, dorsal, anal, and caudal are blue-black, the caudal showing a trace of darker margin; pectoral pale; this specimen also shows purplish brown streaks along the rows of scales on the breast, not evident in our largest specimen, and but faintly indicated in the smaller; these streaks are not of specific value, because they are present in some specimens of A. declivifrons and absent in others. In the 7 inch specimen the head is 3.25 in length; depth 1.63; eye 3.81 in head; preorbital 6.46; interorbital 2.47; dorsal XIII, 14 (13); anal II, 13 (12). In the 5| inch specimen the head is 3.18 in length; depth 1.66; eye 3.47 in head; preorbital 6.60; interorbital 2.07; dorsal XIII, 14 (13); anal II, 14 (13). Abudefduf saxatilis (Linne).

Two specimens 2? to 3? inches long from Toboguilla Island, Panama Bay, among coral in two fathoms of water. Al. C. Z. 29562 (1 specimen). Seventeen specimens 5 to I4 inches long, Perico Island, October 26, 1904, in pool. Three specimens 42 to 6j inches long, Nos. 3371-3, Acapulco, February 28, 1905. No. 3373, M. C. Z. 29632 (1 specimen). The 6i inch specimen had head 3.02 in length; depth 1.65; eye 3.72 in head; suborbital 5.85; interorbital 2.73; dorsal XIII, 13 (12); anal II, 11 (10). In another specimen the dorsal was XIII, 13 (12); anal II, 12 (11); another had dorsal XIII, 14 (13); anal II, 11 (10). The young are easily distinguished from the young of A. saxatalis by the direction of two of the bands; in A. saxatalis the band from about the middle of the spinous dorsal runs downward and slightly forward to the belly, somewhat in front of anal; and the band from posterior part of spinous dorsal extends downward and forward, nearly parallel with other toward front of anal. In A. declivifrons the band from spinous dorsal extends downward and backward to front of anal. The band from the posterior part of spinous dorsal extends down- ward and backward to about the middle of anal ; each band is of about uniform width; in A. declivifrons they are broader dorsally, becoming narrower ventrally, making them appear divergent. In A. declivifrons the bands above the lateral line are much darker, making the pale interspaces appear more distinct (spot- like). 136 THE SHORE FISHES.

In the two smaller specimens the colors are more faded but similar to the smaller specimen just described. 138 THE SHORE FISHES. Halichoeres sellifer Gilbert. Proc. U. S. Nat. Mus., 1890, 13, p. 67. One specimen, No. 3387, 6? inches long from Acapulco. This specimen agrees structurally very well with the description of the Type, except that the caudal is subtruncate or gently rounded; when spread the outer rays are regularly shorter than the middle rays. Gilbert and Starks (Mem. Cal. Acad. Sci., 1904, 4, p. 144) mention specimens from Panama Bay with such caudal. This specimen had been so long in alcohol that the colors can not be deter- mined definitely. There is a trace of a black half-bar on the side of the back from between the 5th and 7th dorsal spines, and indications of other dark markings along back extending downward from dorsal, the first from region of 9th spine and 1st ray; 2nd from 3rd and 5th ray; 3rd from 6th and 7th; 4th from 9th and 10th; 5th a sort of saddle on caudal peduncle, the intensity of these is greatest on the lateral line, below the lateral line is a faded area, and below this an irregular dusky shade most intense in line with the bars; traces of three of four narrow, wavy dusky cross-bars on the dark yellow caudal; other fins all plain yellowish with very slight traces of dusky lines. Head 3.28 in length; depth 3.28; eye 6 in head; snout 3.32; dorsal IX, 11; anal III (?), 12; scales 32-28-83. Halichoeres dispilus (Gunther). Jordan, Proc. Cal. Acad. Sci., 189.5, ser. 2, 5, p. 481.

The 3t| inch specimen has head 3.22 in length; depth 4.14; eye 4.50 in head; snout 3.37; scales 4-27-85; dorsal IX, 11; anal III, 12; a well-developed canine on each side of upper jaw. Color note : — an irregular pale margined ocellus occupying part of five scales lies below space between 4th and 5th dorsal spine, the two central scales being in lateral line; middle rays of caudal covered by a large dusky blotch, within this are three small pale spots. The other specimen can not be distinguished structurally except in the absence of canine teeth in the sides of upper jaw, and slight variation in color. The dark ocellus lies below 4th dorsal spine, and occupies one entire scale and part of two others, one of these lying in lateral line, the others below. No dusky blotch on caudal.

In these specimens, there are numerous small round, grayish spots on the nape in front of dorsal ; in other respects they agree with current descriptions. In some of our young examples there are coarse reticulations of blue lines on the cheek between the hues running downward from in front and from behind the eye. The color of the young is well described by Snodgrass and Heller. TEUTHIDIDAE. Teuthis triostegus (Linne). Chaclodon triostegus Linn£, Syst. Nat. ed. 10, 17.58, p. 274. Eight specimens each about 1? inches long from Manga Reva, February 3, '05. M. C. Z. 29414 (3 specimens). Our specimens agree with Street's account (Bull. 7, U. S. Nat. Mus., p. 67) of Acanthurus triostegus in the color markings with the exception of those on the tail. They also agree with specimens from Samoa in Jordan and Seale's collec- tion labeled T. triostegus. All of our specimens have at least traces of a bar across caudal peduncle and one across base of caudal fin. In most of them the former bar is more distinct; in one instance the bar across base of caudal is more distinct; in one instance the bar extends across caudal peduncle on one side of the specimen and on the other side only partly so. Teuthis umbra Jenkins. BuU. U. S. Fish. Coram., 1903, 22, p. 477. Two examples, Nos. 3181 and 3164, M. C. Z. 29677, 8i and 6i inches long, from Cook Bay, Easter Island. Comparing these specimens with a specimen from Hawaii, we find them identical in color, except that the white on the base of the caudal is not so evident, but it is very faint in the Hawaiian specimen. The profile between the snout and front of eyes is a little more concave in our specimen ; the caudal fins are similar in emargination. For purposes of comparison we give the following measurements of our specimens and of the Hawaiian specimen. No. 3181 has, head 3.77 in length without caudal; depth 1.70; eye 4.09 in head; snout 1.19; interorbital 2.81 ; dorsal IX, 25; anal III, 22. No. 3164 has, head 3.68 in length; depth 1.66; eye 3.77 in head; snout 1,30; interorbital 2.83; dorsal IX, 25; anal III, 23, TFAITHIDIDAE. 145 The Hawaiian specimen, 7? inches long, has head 3.60 in length; depth 1.70; eye 4.10 in head; snout 1.32; interorbital 2.82; pectoral 3.33; dorsal IX, 27; anal III, 23.

The dorsal varies from 29? to 3I2, and the anal from 272 to 292. These were taken among the coral reefs. The following color note made by Mr. Chamber- lain was in the bottle with the specimens : — " They are quite dark in color, showing indistinct darker stripes, which are plainest on caudal region and back; faint pale stripes show on dorsal and anal." The bodies of the specimens show no stripes, but they are evident on the fins; pectoral pale yellowish; the upper ray being margined with black; dorsal and anal each have a narrow black margin. These fins are usually much darker than body color, but in a few specimens they are about the same color; caudal deeply lunate when spread, and appears forked when not spread, the upper and lower rays being greatly produced, this fin is usually darker in color than the body, the rays being darker than the membranes and in some instances the outer rays are each margined with white, the lunate border shows in all the specimens with a narrow margin of white.

Measurements of largest specimen were as follows: — Head 3.8 in body without caudal, 4.19 in total length; depth 6.15 in body without caudal, 6.76 in total length; eye equal to interorbital, 10.5 in head; breadth of head at its junction with nape 1.9 in length of head; maxillary 3.00 in head; dorsal XII, 25, the first three dorsal rays free, without membrane, the 4th provided with a membranejoiningittobaseof 5th; A. 11,28; scales in lateraUine 12+4+26 = 42. Both lips are strongly fringed, anterior nostrils are placed on edge of pre- orbital, with long tubes, which, when depressed, reach nearly to orbit; opercle with about ten rays or cilia. Color in alcohol: — (specimen was somewhat dried). Head above white, a narrow, wavy dark line extending from back of eye downward and backward to edge of preopercle; another fainter line from lower front of eye, downward and backward to behind corner of mouth; body straw colored; a large quadrate brown spot on nape, from this a series of brown spots extend downward across interopercle ; back, along base of dorsal, white; a small brown spot on each side of nape; six small quadrate brown spots at the base of the dorsal, the last one being above the 18th scale of the straight portion of the lateral line; pectoral with two faint dusky cross-bars, one near base, other near middle of fin, rest of fin whitish; other fins yellowish translucent. The second specimen has, D. XII, 24; A.

BLENNIIDAE. 151 General color in alcohol, dull reddish brown; muzzle, s^'lar region and gill-membranes pale; a short dusky bar from eye downward and backward to tip of maxillary; diffuse dusky blotch on opercle; scales with dusky margin; five broad dark brown cross-bars on body, the first extending from front of second dorsal, third from front of soft dorsal, fourth from just anterior to posterior end of soft dorsal; fifth across caudal i^eduncle; on the interspaces between second and third and third and fourth cross-bars a narrow dusky line extending downward from lateral line, and between fourth and fifth a narrow dusky cross-bar; membrane of first dorsal and anterior part of second dorsal black, rest of dorsal fins pale; ventrals pale; pectorals pale with about five broad faint dusky wavy cross-bars; anal pale, membrane broken and gone; caudal pale with a narrow dusky bar across base, followed by a diffuse dusky blotch, and a broad jet black terminal margin. We also have seven other small specimens M to f| inch long from Acapulco, anal rays 16 and 17. M. C. Z. 29587 (4 specimens). The general color is pale straw. Five of these have three black spots with white centres on the top of head, one of the spots is behind each eye and one of occiput just before first dorsal; another (the smallest) has the three black dots similarly situated but^without the white centre; another (the largest) has but one black spot, it is on the occiput and lacks the white centre; a short black cross-bar at posterior base of isthmus in front of ventral, another on belly just back of base of ventral; a black dot at base of each soft dorsal ray and two on top of caudal peduncle and two on its lower edge; base of each anal ray black, this color joined to the ray behind it by a black line; a black line across base of caudal. The largest of these seven specimens shows traces of dusky bars on caudal fin. Jordan and Evermann (loc. cit.) state that the anal is II, 11 (misprinted II, 17) in the original description. This could not be verified from the fact that the Type can not be found. The present specimens, if correctly identified, show that the original count was probably correct.

The large female specimen with eggs gives the following measurements: — head 4.41 in length; eye 4.80 in head; interorbital 2 in eye; ocular tentacle, acutely triangular, fringed on one side; nasal cirrus palmate; a simple cirrus on each side of nape at junction of occiput; upper lip with lobate margin; large hooked teeth posteriorly in each jaw; dorsal XII-15, not extending on to the caudal; anal 16, with one papilla in front; no crest. Color in alcohol, head light brownish, with purplish area on upper posterior part of cheek; a faint dusky, short band-like area at corner of mouth; broad faint dusky bar from front part of each eye across lip, and one midway between; an oblong black spot on side of head, behind eye and directed upward and back- ward, apparently ocellated in life; no bands or spots evident on throat or gill- membranes; faint brownish saddle-like bar across back at insertion of spinous dorsal, not extending down to pectoral; seven pairs of dark brown bars, some- what interrupted, on the side of the body, the fourth pair situated under the notch between the dorsals, one of the pairs extending down from posterior part of spinous dorsal, another from origin of soft dorsal; pectoral translucent, punc- tulate with dusky, most intense on lower rays; ventrals pale, finely punctulate with dusky; spinous dorsal translucent, finely punctulate with dusky, in large rather indefinite spots, approximating two rows, those near the outer margin to some extent coalescing and forming an irregular dusky inframarginal band, margin pale; soft dorsal translucent, finely and faintly punctulate, about three blackish spots on each ray forming about nine or ten downward and backward series or partial series of spots; anal similar in appearance to spinous dorsal; caudal plain translucent with about seven small blackish spots on each ray BLENNIIDAE. 155 forming wavy cross series. The other specimen, a male 2^ inches long taken at the same place and time has similar coloration; dorsal XII-14; anal lG+2; papillae in front. We have four other specimens 1^ to 2i5 inches long from Easter Island, shore. The 2ts inch specimen is a female with eggs, has no crest, and dorsal XII-14; anal 1, 16. Another 2ys inches long, a female with eggs, no crest; dorsal XII-15; anal 1, 16. Another 2fs inches long, a female with eggs, no crest; dorsal XII-14; anal 1, 16. A male 21 inches long, from Samoa and identified by Jordan and Scale as A. striatus, has practically the same coloration except that the markings on the fins are a little coarser and darker and there are white streaks on under part of head (throat) converging backward. This specimen gives the following measurements, head 4.36 in length; depth 5.54; eye 4 in head; interorbital 2.33 in eye; a fringed tentacle on top of eye; nostril tentacle palmate; a simple tentacle on each side of nape; dorsal XII-16; anal 1, 18. We have compared the type of A. thalassinus Jordan and Scale with our specimens and cannot find that it differs. The Tj^pe is a young fish and con- siderably faded, but there are evident traces of the color markings of A . striatus, and it agrees in all other respects.

Color in alcohol, head purplish gray above, very light below, the gray of top of head extending as narrowing streaks across the cheeks, gill-membranes and opercles; two streaks starting at lower posterior margin of eye, extending obliquely backward, uniting behind corner of mouth into a single dark line; a dark line from each corner of mouth on throat, converging posteriorly but not quite meeting; in front of these two similar lines meeting; about eight narrow dark lines or bars across upper lip; crest blue-gray with twelve or fourteen small round black spots on its posterior two thirds and one on anterior portion, a jet black pale edged margin above the posterior spots; pectoral pale, finely punctu- late with dusky ; spinous dorsal gray with about six large, poorly defined brown spots along base, and a broad irregular brown narrowly pale edged margin, membranes with numerous small brown spots and dots; soft dorsal grayish with a margin similar to spinous dorsal and numerous narrow white lines run- ning obliquely downward and forward; anal pale at base, outer two thirds dusky; caudal with a brown spot at base of middle rays, base of caudal other- wise yellowish, remainder translucent, crossed about its middle with a broad faint brown bar, the lower rays and terminal margin broadly dusky; belly plain white; back and sides, anterior margins of soft dorsal and anal gray with num- erous round brownish spots, around which the ground color makes pale vermicu- lations; about four pairs of broad irregular brown cross-bars on body under soft dorsal and on caudal peduncle; commencing just back of a point above the origin of anal is a longitudinal series of short white lines and spots which termi- BLENNIIDAE. 157 nate at lower edge of brown caudal spot; between this series and the soft dorsal are numerous round white spots and vermiculate white lines. A female 2n inches long has the following measurements: — head 4.54 in total length without caudal; depth 5.55; eye 4.05 in head; dorsal XII, 20; anal II, 20; interorbital very narrow; ocular cirrus long and fringed on both sides; nasal cirrus comparatively long and simple; no cirrus on nape; crest well de- veloped. Color of head and body very similar to that of the male, but on the middle of the under lip there are two short converging lines; pectoral, ventral, anal, and caudal pale, but finelj^ punctulate with dusky; caudal having a yellowish area and brown spots at its base; 1st and 2nd dorsal similar to those of male, but much paler. Of the remaining four specimens three are females having dorsal XII, 19 and anal ii, 20, the two anterior represented by the ii being shorter than the others, the first papilla-like, and separated from the rest of the fin; the second connected by a membrane and may be considered a ray. The fourth and smallest specimen is a male having dorsal XII, 20 and anal ii, 21, the anterior of which is a simple papilla and the second a short ray con- nected by a membrane to the rest of the fin. These specimens agree perfectly with the description of Salarias biseriatus Cuvier and Valenciennes {loc. cit.) and the description and figure by Kner in Novara Reise Fische, 1865, p. 197, taf. 8, fig. 4, with the exception that both of these authors state that there are no posterior canine teeth on the lower jaw; the present specimens possess large canine teeth, although their location is such that they might be easily overlooked. Dr. Steindachner has kindly sent us one of Kner's specimens taken at Tahiti. Upon examination we find that it possesses large canines well back in the mouth but in such a position as to be easily overlooked. It is a female without crest, containing well-developed eggs. Specimens in the Reserve Series of the U. S. Bureau of Fisheries have been misidentified as Salarias biseriatus by Jordan and Scale, Bull. U. S. Bur. Fish. 1906, 25, p. 427. These we describe as Alticus margaritatus, sp. nov. Plate 7, fig. 3, Plate 8, fig. 1. Twenty-seven specimens | to 2| inches long from Pago Pago, Samoa. The Type, No. 65409 U. S. N. M., a male 2| inches long has the following measure- ments: Head 4.66 in total length without caudal; depth 5.35; eye 4.51 in head; dorsal XII, 18; anal 21. 158 THE SHORE FISHES. Canines present, orbital cirrus developed only on right side, comparatively long with very short fringes; nasal cirrus on left side simple, on right side with two short branches at base; no cirri on nape; crest long, of moderate height, extending from between eyes almost to first dorsal; dorsal deeply notched; first slightly connected with second by membrane; first dorsal with rather high flexible spines, but somewhat lower than soft dorsal; anal con- siderably lower than soft dorsal; dorsal and anal entirely separate from caudal. General color warm brown, paler on belly; head with a slight purplish tinge, darker on snout and lips; only a slight trace of cross-bars; numerous small pale pearly spots, most numerous posteriorly, below median line forming a longitudinal series arranged more or less in pairs; above the median line these having no regular arrangement; larger pale areas on body above anal base. Crest on head dark brown, thickly dotted with small pearly or bluish spots; pectoral dark brown; spinous dorsal dark brown with a series of large oblique oblong black spots, one on each interspinous membrane; second dorsal dark brown with numerous narrow pale, very oblique streaks running upward and backward, their widths about equal to the interspaces, barely perceptible to the naked eye; caudal dark brown, appearing almost black to the naked eye; anal dark brown, with darker margin; ventral short, black. A cotype, a female 2jg inches long has following measurements: — head 4.25 in total length without caudal; depth about .5. ; eye 4. .50 in head; dorsal XII, IS; anal i, 20. Cirrus above eyes quite long and strongly fringed; a short simple cirrus above each anterior nostril; no cirrus on nape; crest low, shorter than in male, commencing above posterior margin of eye and extending to junction of nape with occiput. General body color paler than in male; about six pairs of faintly defined dark brown cross- bars; the pearly spots are more distinct than in male and more numerous anteriorly; those at base of anal scarcely discernible; head covered with small dusky spots; crest without white dots; vertical fins paler than in male; large black spots present only on first and second interspinous membranes; soft dorsal similar to that of male but paler; anal paler, each ray tipped with white; caudal lighter than in male; pectoral dusky olive; ventral pale, punctulated with dusky dots. Younger individuals much paler, cro,ss-bars and spots becoming more distinct; some with an oblong dusky spot behind eye. The smaller specimens have no crest. The fin-ray counts in these specimens run as follows: — dorsal XII-XIII, 17 to 18; anal 19 to 21. Salarias lineatus Cdviek & V.\lenciennes. Hist. Nat. Poiss., 1836, 11, p. 2:i2 (314).

Z. 29537 (2 specimens). The following color note was found with these: — "General color brownish slate; stripes pale greenish, black and white margins on the soft dorsal, the brown stippling [on] caudal parts."

Thirty-nine specimens, Ij to 4s inches long from Manga Reva. M. C. Z. 29422 (9 specimens). BATRACHOIDIDAE. 159 The following color note was found with these specimens: — "Those with crest, bars slate light green, belly white, lips and chin darker. Tip of anal rays pale slate, membrane nearly black. In some, brown verniiculations over green bars. Those without crest — similar to others, with dark brown spots on caudal portion and dorsal and anal fin." These specimens bear out the conclusions of Giinther {loc. cil.) regarding the sex of this species and the identity of S. edentulus and S. rivulatus. Eleven of these are adult males 3ii to 4n inches long, possessing the color of S. rivulatus and the crest on the head. Twenty-three of these, 2h to 4s inches long are adult females, of these twenty are without a crest, or with a slight indication of cre^t, the remaining three, which are the largest have a low but distinct crest. These conform in color with S. edentulus. There are five young individuals Ij to Ig inches long, which do not show any crest, and the coloration is not easily made out. All of the above of both sexes in addition to the fringed cilia on the nostril and the simple one above the eye, have one on each side of the nape close to the occiput. BROTULIDAE.

Two specimens 2h and 3| inches long from Acapulco. M. C. Z. 29541 (1 specimen). The statement by Jordan and Evermann (loc. cit.) that the snout is 7 in head must be a mistake as Gill gives it as 5 and from an examination of his Types and of our specimens it is found to be 4? to 5, depending somewhat on the size of the specimen.

These specimens ranging gradually from 2 to li^ inches have the eyes sym- metrical. The eyes are just as symmetrical in the largest as in the smallest and the structure of the specimens superficially shows no great difference in the various sizes. Dorsal 86 to 90; anal 65 to 68. These specimens are provision- ally identified with this species, mainly because they agree in dorsal fin ray counts more closely than with P. consiellatus, the other species recorded from the Galapagos Islands. They show no color markings or pigmentation. SOLEIDAE. Achirus mazatlanus (Steindacuner). Jordan, Proc. Cal. Acad. Sci., 1895, ser. 2, 5, p. 505. Solea mazallanus Steindachner, Sitzb. Ak. Wiss. Wien, 1869, 60, p. 267. One specimen, 4i inches long from Panama Market, October 28, 1904. Depth 1.60 in length without caudal; head 3.5; gape 2.95 in head; eye 10.2; interorbital 1 in eye; scales about 70; dorsal 57; anal 45; pectoral 5, middle ray about twice as long as the others; no pectoral on blind side; two ventrals, each consisting of five rays, that on the eyed side on the ridge and continuous with anal, somewhat lower on other side and not continuous; upper and lower margins of caudal rounded, the rays graduated in length from the base to the fifth ray, in each margin, the fourth and fifth rays longest and produced some- what beyond the straight terminal margin of the fin; each caudal lobe about 1.33 in head; middle ray 1.55 in head; longest dorsal ray 1.75 in head; longest anal ray 1.7 in head; these longest dorsal and anal rays are posterior to middle of body which gives the fish an ovate outline. Developed scales about seventy, strongly ctenoid on body, and vertical fins and on both sides of fish. Scales of 162 THE SHORE FISHES. the eyed side of head ctenoid, those of other side, when present, merely ciliated; opercle and posterior and inferior borders of preopercle scaleless, except about three rows on upper posterior edge of opercle; head everywhere on eyed side thickly covered with fine pale ciUa; lower lip with a fringe of large cilia; Wind side of head in front with low, strongly ciliated folds or flaps; numerous fine cilia everywhere on the eyed side, anteriorly some of them black, more numerous on the rays of the fins; on blind side cilia are not so numerous on body, groups of them are arranged along the lateral line. Color on eyed side, dark gray, body crossed by faint, fine, hardly distin- guishable dusky lines; vertical fins and caudal gradually darker toward margin, with a narrow pale margin ; blind side of head and body white. This specimen agrees closely with A. mazatlanus, differing only in the form of the caudal, which is slightly lunate. This character alone and in but one specimen is scarcely sufficient to justify the description of a new species. Achirus klunzingeri (Steindachner). Jordan & Everm.oin, Bull. 47, U. S. Nat.

This Station is near Galapagos Islands. We provisionally identify the specimen with this species. The identification is not at all certain and is made solely because the species has been recorded from the Galapagos and because it agrees very well in vertical fin rays, the dorsal having 100 and anal 80 rays. It is a larval form without color-markings; the eye has apparently just BALISTIDAE. 163 begun its migration from the right to the left side, and what appears to be a yolk-sac i.s not absorbed. It would almost seem that such a large larval form must be abnormal. BALISTIDAE. Batistes capistratus 8uaw. Gen. Zool., 1804, 5, p. 417. Jordan & Evermann, Bull. 47, U. S. Nat.
