285 
along lower part of side to lower base of caudal fin; a similar line backward from eye under lateral 
line, ceasing above pectoral, another from forehead across upper edge of eye, crossing upward to nape, 
thence along base of dorsal to caudal peduncle; side of head washed with bluish, the under part with 
bluish and Chinese white; breast pale bluish with brighter bluish spots; fins all pale or dusky white. 
Above description based upon a specimen (No. 05748) 4.6 inches long, obtained at Honolulu; 
life color taken from specimen (No. 03031) 4.25 inches long, obtained at Honolulu, June 7. Our 
collection contains one other specimen (No. 03231) 4.1 inches long, obtained at the same time and 
place. In addition to these, we have examined 21 specimens collected by Dr. Jenkins, and others 
obtained by the Albatross at Honolulu, where the fish appears to be common. The length varies from 
4 to 5 inches. 
Original type locality unknown. The species has been recorded from Maui and Honolulu.

Genus 151. HALICHCERES Ruppell. 
Body oblong, compressed, not elevated, covered with large scales, 25 to 30 in the lateral line, 
which is not interrupted, but bent abruptly behind; scales on breast a little smaller; head scaleless, 
compressed conic; preopercle entire; teeth large, 2 to 4 strong canines in front of each jaw, a posterior 
canine tooth; fin rays usually D. ix, 11; A. iii, 11; fins low; caudal lunate, truncate or rounded; 
ventrals inserted under axil of pectoral; gillrakers short and feeble; gill-membranes slightly joined 
to the narrow isthmus; no scaly sheath at base of dorsal; vertebrte 10 -|- 15 = 25. Species 
numerous, of rather small size and gay coloration, the typical species (with canines j) all belonging 
to the East Indies and Polynesia, those with canines \ (Iohtlvy callus) being all American.

A. nr, 12; scales 4-28-8. 
Body short,' slender and greatly compressed; dorsal outline rather straight from tip of snout to 
occiput, thence gently arched in a long curve to base of caudal; ventral outline a longer lower curve; 
head small, much longer than deep; snout long, sharply conic, jaws each with a pair of strong canine 
teeth anteriorly, and a row of close-set shorter teeth on the sides; eye small, lower edge of orbit on 
axis of body; interorbital convex, the nape trenchant; caudal peduncle moderately deep, 2 in head; 
preorbital oblique; preopercle and opercle smooth, the latter ending in a long pointed flap; scales 
large, thin, their edges soft, surface delicately striate; scales on breast and nape much reduced; head 
entirely naked; lateral line complete, following curvature of back for 20 scales, then descending 3 rows 
and continuing to base of caudal; spinous dorsal low, its spines weak, about equal to snout, dorsal rays 
somewhat longer and about equal to distance from tip of snout to posterior edge of pupil; anal similar 
to soft dorsal; caudal slightly rounded, the outer rays slightly produced; ventrals long, the outer rays 
produced, reaching vent, 1.6 in head; pectoral small, slender, as long as ventrals.
