Subgenus CAREMITRA, Jordan & Evermann. 

 2460. CAREPROCTUS SIMUS, Gilbert. 



A species with a very heavy head and body, an inferior transverse 

 mouth, overlapped by the thick, rounded snout. Appearance much that 

 of RJiinoliparis barbulifer, but the anterior parts much heavier, nape more 

 elevated, snout shorter and blunter, without barbels, extending beyond 

 front of eyes for a distance (measured axially) equal to diameter of orbit, 

 and projecting beyond mouth for that distance. Mouth transverse, its 

 width nearly twice the distance from symphysis of lower jaw to angle of 

 mouth, the latter reaching a vertical midway between front of eye and 

 pupil. Teeth indistinctly tricuspid, in narrow bands, 11 or 12 series in 

 each half of lower jaw, 8 or 9 in the upper. Nostrils without tube. Eye 

 large, 3 in head, equaling snout, 1| in total interorbital width. Gill slit 

 moderate, f of it opposite upper pectoral rays, its width $- diameter of eye. 

 Opercle prolonged into an acute lobe overlapping middle of slit. Disk 

 rather small, round, under posterior part of eye, its diameter J that of eye. 

 Vent immediately behind it, equidistant from front of anal and angle of 

 mouth. Pectorals inserted high, the upper edge on a level with the mid- 

 dle of eye, continuous, the median rays greatly shortened, the lower ones 

 again longer, with exserted free tips ; upper lobe extending beyond front 

 of anal, and equaling length of head behind snout, lower rays length of 

 upper ones; P. 33; origin of dorsal fin just behind axil of pectorals, con- 

 tinuous posteriorly with the caudal fin, which is very narrow and not dis- 

 tinct; origin of anal at end of first third of length. Whitish or bright 

 brown, dusky posteriorly on body and fins; mouth, gill cavity, and peri- 

 toneum white. One specimen, 3| inches long, from Bering Sea north of 

 Unalaska Island. (Gilbert.) (simus, diju.6$, snubnosed.)

 2461. C4REPROCTUS COLLETTI, Gilbert. 



Head 5, blunt and heavy, with subvertical cheeks and bluntly rounded 

 snout, the latter not projecting beyond the mouth; greatest depth (at 

 occiput) 6 ; eye equals length of snout, 3f in head, If in interorbital width ; 

 nape not elevated; mouth terminal at lower side of snout, slightly oblique,
