not firm. Gills 3i, no slit behind the last arch ; gill-membranes broadly 
joined to the isthmus, their union extending to above the lower edge of 
the base of the pectorals. Pseudobranchire very small; no cirri, scales, 
or prickles; the skin thin and movable, smooth, or roughened with small 
warts. Spinous dorsal little developed ; the two fins usually continu- 
ous ; spines very slender, flexible, imbedded in the skin ; pectorals short, 
procurrent below; ventrals very short, well separated, their rays 1,3; 
caudal rounded. Deeper parts of the Atlantic; very closely related to 
PsycJirohites. (A diminutive of Cottus.) 
1044. C. mici’ops Collett. 
Pale, with three broad dusky cross-bands on body and fins, one on 
head, one through spinous dorsal and pectoral, one through second 
dorsal and anal, besides a small band at base of caudal. Head very 
large, its length, breadth, and depth nearly equal; the greatest depth 
at the nape; four bony tubercles on top of head and some at the sides, 
all covered by the skin; lower jaw included; maxillary extending to 
below the middle of the eye, which is equal to the snout, and about 4^ 
in head; suborbital stay and the roughish edge of the preopercle both 
covered by smooth skin; chin and preorbital with pores. Skin every- 
where thin, somewhat movable, its surface roughened by small blunt 
warts. Dorsal fin continuous, the feeble spines lower than the soft 
rays; pectorals barely reaching anal; caudal long. Head 2f ; depth 3J. 
D. YI-10; A. 10. L. 8 inches. Deep water olf the coasts of Xorway 
and of Ehode Island; lately taken by the United States Pish Commis- 
sion. The specimens here described by us difter somewhat from Col- 
lett’s description, but the very small size of the original types may jjer- 
haps account for the discrepancies.

Color yellowish, the fins all dusky; no cross-bars. General form and 
appearance of C. microjys, but the head still larger, and the skin iier- 
fectly smooth, very thin, loose, and movable as in Liparis. Tubercles 
on head stronger, more numerous, covered by skin, but more spine-like, 
the bones firmer; spinous dorsal still feebler and more concealed. 
Head 24; depth 34. D. YII-14; A. ca. 15. L. 6 inches. Deepwater 
oft" the coast of Ehode Island; lately taken by the United States Fish 
Commission.
