presence of coeca could be detected in only one specimen, in which 

 six very short and small coeca were found adhering closely to the 

 pylorus. In another specimen some filaments may have represented 

 coeca. 



In this species the dorsal fin is more or less distinctly notched and the 

 anterior rays are not buried but project distinctly. The anterior dor- 

 sal ray is typically longer than the two or three succeeding rays. In 

 one or two specimens the anterior ray is about equal to the succeeding 

 rays and thus resembles the condition found in C. curilanus. In No. 

 64043, U.S.N.M., larger specimen, the first dorsal ray is contained 

 3.4 in the head, the third ray 5 ; in the smaller specimen the first dorsal 

 ray is contained 2.6 in the head, the second ray 3.3, and the fourth ray 

 5.5, the following rays increasing in length. 



The specimens No. 64043 are lighter than the type, being grayish 

 and resembling the coloration of C. curilanus. 



CAREPROCTUS SIMUS Gilbert 



Careproclus simus Gilbert, 1896, p. 444. 



Type.— 'No. 51688, U.S.N.M.; Albatross Station 3331, Bermg Sea; 



north of Unalaska; depth 350 fathoms. Length 71 + mm. (Caudal 



absent.) 



Distribution. — Bering Sea, north of Unalaska, Albatross Station 



3331; depth 350 fathoms. 



Relationships. — In most respects C. simus agrees with C. mollis^ 



differing in the projecting snout and larger eye. In general appear- 

 ance, especially in the broad 

 head, C. simus resembles C. 

 spectrum and related species. 

 It resembles C. curilanus in 

 the projecting snout, possibly 

 in the condition of the ante- 

 rior dorsal rays and in other 

 characters. The dentition 

 of these two species is quite

Description. — Dorsal 47+ ; anal 41 + ; pectoral 33; pyloric coeca

Body rather deep at union with head, tapering rapidly for a short 

 distance, then more gradually until the tail becomes attenuate. Head 

 heavy, broad, flattened on top, resembling C. spectrum; depth of head 

 greater than width of head; profile descending gradually to tip of 

 snout and then retracting to the mouth. Mouth broad, the angle
