FISHES FROM THE HAWAIIAN ISLANDS. 
189 
head; anal similar to soft dorsal, longest ray 1.25 in head, second spine longest, 2 in head; caudal 
forked, upper lobe the longer; ventrals reaching past vent, outer rays longest, about equal to head; 
pectoral broad, upper rays longest, equal to head; scales large, ctenoid, covering entire body and 
head except lower jaw and snout anterior to eye; lower limb of preopercle scaled; large scales cover- 
ing nearly all of dorsal spines, smaller scales covering as much of soft dorsal and anal and nearly all 
of caudal; very minute scales on base of pectoral, none on I'ays of ventrals; lateral line concurrent with 
dorsal outline, on 22 scales, ending 3 rows of scales short of posterior base of dorsal, then dropping 
3 rows of scales and continuing obscurely on middle of caudal peduncle to base of caudal fin. 
Color in alcohol, uniform very dark brown, nearly black; 2 narrow wavy bands of white on side, 
first beginning about under fourth dorsal spine and extending under about middle of pectoral, thence 
curving slightly backward toward vent, rather indistinct below pectoral; second band beginning under 
last dorsal spine and first ray, extending toward middle of anal, rather obscure, indistinct for 2 or 3 
scales before reaching anal; fins all black, pectoral slightly lighter than others; a large black ocellated 
spot with a narrow white border on back and lower part of soft dorsal, larger than eye, just back of 
last white bar. 
This species agrees with typical Glyphisodon in all respects except that none of the teeth appears 
to be emarginate. It agrees with Chrysiptera in the entire preopercle and preorbital and naked snout, 
but differs from the type of that genus in having the teeth in a single series. 
The above description based on the type, No. 50669, U. S. N. M. (field No. 04524), a specimen 3.75 
inches long, from Honolulu. One other specimen obtained. It is taken as a cotype and is No. 2727, 
U. S. F. C. reserve series (field No. 03732), a specimen 2.75 inches long, from Kailua, where it was 
first discovered by Michitaro Sindo, for whom the species is named. 
34. Pomacentrus jenkinsi Jordan & Evermann, new species. 
Head 3.4 in length; depth 1.8; eye 3.3 in head; snout 4; maxillary 3.2; interorbital 2.75; D. xm, 
16; A. ii, 13; scales 4-29-11; Br. 4. 
Body ovate, deep, compressed, dorsal outline rather steep, evenly curved from tip of snout to soft 
dorsal, following edge of scales on spinous dorsal; head deeper than long, compressed subconic; snout 
bluntly conic, jaws equal; maxillary reaching anterior edge of eye; mouth small, horizontal; a single 
row of close-set, incisor teeth in each jaw; posterior edge of preopercle roughly serrate; opercle ending 
in 2 short flat spines, the upper very obscure; interorbital wide, strongly convex; fins rather large; 
origin of dorsal over ventral, origin of each equally distant from tip of snout; first 2 or 3 dorsal spines 
shorter than others; others about of equal length, shorter than the longest dorsal rays, the median rays 
being longest, 1.5 in head; caudal forked, lobes rounded, upper the longer; anal rounded, longest ray 
1.5 in head, second spine rather stout and strong, 2.2 in head; ventrals long, reaching vent, 1.1 in head; 
pectoral broad, upper rays the longer, 1.2 in head; scales large, finely ctenoid; body and head, except 
lower jaw and snout, scaled, scales on top of head small; bases of all the fins except ventrals well 
covered with fine scales, those on spinous dorsal larger; lateral line concurrent with dorsal outline to a 
line under base of third or fourth dorsal ray, where it drops 3 rows of scales to middle of caudal 
peduncle, whence it continues to base of caudal fin, the detached portion little developed. 
Color in life, ground color dark drab; central portion of scales olivaceous, each one with black on 
lower part of posterior edge forming vertical bands on body; axil black; outer border of dorsal fin, 
above scaled part, black; pectoral dusky olivaceous, black at base; ventral and anal black; caudal 
dusky with posterior border lighter; iris bright yellow. 
Color in alcohol, dark brown, edges of scales darker; a dark stripe on upper edge of membranes 
of spinous dorsal, broadest and most distinct anteriorly; rest of dorsal, and caudal and pectoral dark 
brownish; ventrals and anal dark, almost black; a black blotch at upper base of pectoral, continuous 
with the black axil. 
This is a very abundant species among the Hawaiian Islands. Numerous specimens were obtained 
at Honolulu in 1889 by Dr. Jenkins, and others by Dr. Wood in 1898 and Dr. Jordan in 1900. Our 
own collections, made in 1901, contain numerous SDecimens, the localities represented being Honolulu, 
Hilo, and Kailua. 
The above description is based chiefly upon a specimen (field No. 04526) 4.8 inches long, obtained 
by us at Honolulu.
