BULLETIN OF THE UNITED STATES FISH COMMISSION. 
Scales fallen, with the exception of 2 or 3 along the course of the lateral line, which runs along 
middle of sides, and describes anteriorly a convex curve above pectoral fin; scales like those observed 
in other species of the genus, without spines, marked with very numerous striae, which are roughened 
by a series of minute prominences; they covered entire body, but their presence on head can not be 
verified, owing to the condition of the type. 
Color, head and fins light grayish, margins of the scale pouches dusky; head light grayish on top 
and sides, except opercle and gill-membranes, which are black; belly, gill and gular membranes, and 
the inner lining of cheeks and opercles black; breast, shoulder girdle, isthmus, lips, and lining of 
mouth dark brownish ; peritoneum dusky. 
A single specimen was obtained. 
Chalinura ctenomelas Gilbert & Cramer. 
This a very abundant species in depths of 250 to 350 fathoms. 
As seen from above, the terminal portion of snout is broadly triangular, tapering rapidly forward 
to the angular tip, which is about on level of middle of eye; maxillary reaching to or slightly beyond 
hinder margin of orbit, its length slightly less than half length of head; outer series of enlarged teeth 
in upper jaw weakly arrow-shaped, the shape most apparent in the lateral teeth of the series; the 
villiform mandibular teeth are in 3 irregular series and have distinctly arrow-shaped tips, as have 
also those of the mandibular band, which are arranged in 2 irregular series; angle of preopercle 
produced, the posterior margin running obliquely upward and forward, incurved above the angle; 
spinelets on scales not arranged in longitudinal series, but in definite oblique series (quincunx order). 
A small naked pit lying between bases of ventral fins is separated by a narrow band of scales from 
the scaleless area surrounding anal opening; in some specimens the 2 areas seem to be connected by a 
narrow naked line, in others by a broader naked streak, but it is considered probable that these con- 
ditions were due to the loss of scales; distance between dorsals varying from twice to nearly thrice the 
base of anterior dorsal; mouth-cavity white, black only in extreme posterior part; gill-cavity largely 
white anteriorly, black above gills, on opercular region, and lining of shoulder-girdle.
