620. BULLETIN OF THE UNITED STATES FISH COMMISSION.

Scales large, the free margins finely ctenoid, rough to the touch; head wholly scaled as far forward as front of orbits; the short snout naked; exposed portion of maxillary scaled, but no scales can be detected on mandibles, or branchiostegal membranes; lateral line a ascending rapidly to the back, and running along base of dorsal fin, separated from it by a series of narrow half-scales which more or less coincide with and overlap the scales of the lateral line.

Color in life; - light purplish red on upper parts, silvery below, a few minute scattered blue spots on posterior half of caudal peduncle; pectorals translucent; other fins light purplish red; anal margined with yellow; the projecting tips of membranes of dorsal spines yellow.

Family Pomacentridae.

Chromis leucurus, new species. Plate 77, fig. 2.

Type, 66 mm. long, measured to tip of middle caudal rays, from station 3875, Avau Channel, between Maui and Lanai, depth 34 to 65 fathoms; type, 51587, U. S. Nat. Mus.

Length of head 32 hundredths of total length to base of caudal (50 tn.); greatest depth 51; least depth of caudal peduncle 16; diameter of orbit 12; interorbital width 11; length of maxillary 9; length of snout 9; distance from tip of snout to front of dorsal 40; highest dorsal spine 19; longest dorsal ray 25; second anal spine 23; filamentous caudal rays 60; length of pe;Aoral 35; length of ventral 34. D. xi', 14, the last ray cleft to base; A. if, 15; P. 16. Tubes in lateral line 13; cross-series of scales 20 or 21.

Body short and deep, resembling Pomneentrus, with a short high caudal peduncle, which does not conspicuously taper toward tail; head short and small, a little less than one-third length, eye large, a little more than one-third head; mouth small; maxillary barely reaching vertical from front of eye; in the front of each jaw a wide band of villiform teeth, preceded by a single series of strong conical acute teeth, a little flattened at base, but uniformly tapering to the acute apex; the anterior series is continued on sides of jaw, the teeth of this series much reduced in size; free margins of preorbital and preopercle entire.

Dorsal spines evenly graduated, none of them as long or strong as second anal spine; both anal and soft dorsal have acute lobes, with filamentous tips which extend well beyond base of caudal; caudal. deeply forked, both lobes filamentous, produced in long thread-like streamers; outer ventral ray filamentous, reaching same vertical as pectoral, which terminates above first soft ray of anal.

Scales large, ctenoid, caducous, rather irregularly imbricated; lateral line terminating under last dorsal spine.

Color in life, deep brownish black, more intense posteriorly and on soft-dorsal and anal fins; posterior half of caudal peduncle and caudal fin white, as are also tips of posterior dorsal and anal rays; a blackish spot on base of pectorals, a lemon-yellow band behind it across basal portion of fin; ventrals lemon-yellow, outer ray and spine dusky; in a young cotype, the sides are much lighter, becoming dusky on caudal peduncle; soft dorsal and anal black.
