102 DEEP SEA FISHES. 
on the first arch; rakers six on each of the first two arches, short, thick, 
rounded; gill openings smaller than the pupil, little forward of the vent, 
placed superiorly in the axilla. Branchiostegal rays six, all resting 
against the ceratohyal, outer one much larger and stronger, firmly joined 
to the lower side of the outer edge of the suboperculum. Operculum nar- 
row anteriorly, much broadened backward; suboperculum broad, with a 
feebly developed four to six spined tubercle at the angle of the disk. 
Skin of the upper surface covered with unequal, closely set, sharp cusped, 
broad based tubercles, with radiating ridges on the bases, larger and 
bearing two or more cusps along the edge of the disk, yet larger along 
the middle of the back and in somewhat regular series on the tail, else- 
where more closely set and surrounded by smaller narrow based slender 
spines. The radiating ridges of many scales bear very small cusps. Scales 
of the ventral surface fine and sharp. The lateral line is easily traced 
by the rounded sensory papille, of which there are about a dozen in the 
series from the snout over the eye and the back to the side of the tail. 
At each side of each papilla there is a spine and a fleshy lobe, more or less 
fringed, by which it is protected and hidden; on the lower side of the 
disk the line forms a deep channel crossed by bridges over the papillae. 
The second papilla at each side of the chin is in front of the space 
between the first and third. 
Dorsal origin about midway from snout to end of caudal, base hardly 
as long as the orbit, greatest length nearly the width of the mouth, 
anal narrow, shorter than the dorsal and originating little backward of 
its hindmost ray; caudal as long as the skull, slightly convex on the hind 
margin; pectorals as long as the caudal, fringed; ventrals narrow, fringed, 
length equal to width of mouth. 
Fresh specimens brownish, more or less gray, with rather faint and 
ill defined spots of light brown somewhat closely placed over the disk ; or 
in cases with white vermiculations in the brown, or in others with whitish 
spots over a brownish surface; ventral surface uniform light; orbits 
darker.
