not firm. Gills .'U, 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 

 Psyclirolutes. (A diminutive of Cottus.) 



1O44. C. microps Collett. 



Pale, with three broad dusky cross-bands on body and fins, one on 

 head, one through sp incus 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 4i 

 in head; suborbital stay and the rough ish 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 1'r! ; depth 3J. 

 D. VI-19; A. 10. L. 8 inches. Deep water off the coasts of Norway 

 and of Ithode Island ; lately taken by the United States Fish Commis- 

 sion. The specimens here described by us differ somewhat from Col- 

 lett's description, but the very small sixe of the original typos may per- 

 haps account for the discrepancies.

1OI5. C. torvus Goode. 



Color yellowish, the (ins all dusky; no cross-bars. General form and 

 appearance of C. ////r/-o/>.v, but the head still larger, and the skin per- 

 fectly smooth, very thin, loose, and movable as in IJimrin. Tubercles 

 on head stronger, more numerous, covered by skin, but more spine-like, 

 the hones firmer; spinons dorsal still feebler and more concealed. 

 Head L'A; depth .">A. I >. VI 1-14; A. ca. 15. L. 6 inches. Deep water 

 oil' the coast of Rhode Island; lately taken by the I'nited States Fish
