trenchant; spinous dorsal low and weak, 2.5 in head; origin of soft dorsal midway between tip of 
snout and fork of caudal, longest ray 1.5 in head; caudal deeply forked; longest anal rav 1.65 in head, 
origin of fin under about seventh soft dorsal ray; ventrals short, reaching past vent, 2.1 in head; 
pectoral long and falcate, reaching beyond arch of lateral line, slight!)' longer than base of anal; arch 
of lateral line dropping rather suddenly from under last dorsal spine to the straight part under third 
soft dorsal ray, chord of arch 1.4 in straight part; scutes on entire straight part; breast naked except 
a small patch of scales near center; cheek, postocular region, and upper part of opercle scaled, rest of 
head naked, body completely scaled; dorsal and anal fins scarcely sheathed. 
Color in life, very pale olive, side white: head greenish; no opercular spot; no spot on pectoral; 
base of pectoral dark; both dorsals edged with blackish; upper lobe of caudal blackish, especially the 
edge, lower lobe bright yellow; anal bright, light yellow, the edge whitish; ventrals whitish with 
yellowish streaks along the rays; pectoral pale, the axil blackish. 
Color in alcohol, slaty silvery, becoming lighter below, almost white on belly; spinous dorsal 
dusky; soft dorsal pale, edged with dark, other fins pale, inner axil of pectoral black. 
This species is related to Carangus hippos of the Atlantic, with which it agrees in the small patch 
of scales on the otherwise naked breast, the character of the lateral line, and the teeth. It is, 
however, a much deeper fish, the snout is shorter, the anterior profile rises more abruptly, and there 
is no black spot either on the opercle or on lower rays of the pectoral. The yellow color of the anal 
fin seems to be constant and diagnostic, especially in the young. The species is common at I lonolulu, 
from which place we have examined 13 specimens 2.5 to 22 inches in length.

Body slender, compressed, not greatly elevated; snout rather short, profile ascending to nape in a 
gentle curve, slightly trenchant; mouth large, slightly oblique; lower jaw somewhat projecting; max¬ 
illary reaching posterior edge of orbit, its width at tip 1.5 in orbit; supplemental maxillary well 
developed, its width 3.25 in entire width; gape reaching vertical of posterior edge of pupil; villiform

like; eye large, anterior; adipose eyelid strongly developed behind; supraocular region with 2 ridges, 
extending to humeral region, the lower the stronger; posterior half of body, beginning at origin of 
soft dorsal, long and gently tapering to caudal peduncle; caudal peduncle much depressed, its least 
depth scarcely half its least width; distance from base of last dorsal ray to origin of caudal fin equal 
to snout and pupil; fins small; origin of spinous dorsal posterior to base of pectoral by a distance 
equal to eye; longest dorsal spine slightly greater than snout; anterior rays of soft dorsal somewhat 
produced, about 1.8 in head; anal similar to soft dorsal, its origin under eighth soft dorsal ray, anterior 
ray produced, but scarcely equaling longest soft dorsal rays; caudal widely forked, lobes apparently 
equal; pectoral long and falcate, reaching past origin ofnnal, exceeding head in length by 0.65 diam¬
