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® 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 mar- 
gined with yellow; the projecting tips of membranes of dorsal spines yellow. 
Only the type known.

Family POMACENTRID^. 
Chromis leucurus, new species. Plate 77, fig. 2. 
Type, 66 ram. 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 m.); 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

xii, 14, the last ray cleft to base ; A. n, 15 ; P. 16. Tubes in lateral line 1 3 ; cross-series of scales 20 or 21 . 
Body short and deep, resembling Pomacentrus.,' 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 con- 
tinued 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 fila- 
mentous, 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; pos- 
terior 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. 
Specimens taken at stations 3875, channel between Maui and Lanai, 34 to 65 fathoms, and 3982, 
vicinity of Kauai, 40 to 233 fathoms.
