 tion 5029, southeast of Cape Patience, Sagalin, depth 440 fathoms. 



Measurements in hundredths of lengtli without caudal (43 mm.): 

 Length of head 24; greatest width of head 14; interocular width 10; 

 width at angles of moutli 9; distance from tip of snout to front of 

 eye 8; diameter of eye 6.3; depth of body IS; length of gill slit 3.2;

decreasing regularly downwards, a tew 

 of the lower with weakly exserted tips, and two or three of them a 

 trifle lengthened, the longest not reaching posterior border of disk. 



Color pale to dusky about the head, nearly uniformly dusky on

 abdominal wall. 



In general appearance tliis species closely resembles C. attenuatus, 

 wliich differs in its blunter deeper snout, larger eye, smaller disk, 

 longer first dorsal ray, and especially in its well developed lower 

 pectoral lobe, in wliich the rays are lengthened and strongly exserted, 

 extending beyond the vent.
