 partly free, the upper exserted and reaching a point half way between vent and anal fin. Ventral 

 disk nearly as large as eye, the anterior edge under pupil. Vent close behind disk, the distance between 

 disk and vent 6 in head. 



Skin thin and transparent, covered with fine dark points; in life, uniform light reddish above, 

 whitish below, the reddish very thin, appearing a little mottled with lighter. 



A well-marked species, distinguished by the notch in the dorsal and the large prominent eye.

Careproctus spectrum Bean. 



A single specimen, 50 mm. long, was taken at station 4781 near Agattu Island, in an intermediate 

 haul of 300 fathoms. It may have been taken from the bottom, however, as the net struck ditfing the 

 haul. It differs from the types of C. spectrum in having the eye smaller, 4 instead of 3 in head, and 

 the gill opening 2.66 instead of 2. 



Head 30 hundredths of length without caudal; depth 24; eye 6.5; snout 9; gill slit 10; maxillary 

 16; disk 3; distance from disk to tip of mandible 15; to front of anal 19; dorsal 51; anal 48; pectoral ^2>- 



Head large, flat above, contour from occiput almost to end of snout forming a straight line. Snout 

 short, blimt, not overlapping the mouth; mouth large; maxillar\' 2 in head, reaching vertical from 

 posterior margin of eye. Teeth lanceolate, in narrow bands in each jaw, the inner teeth enlarged and 

 prominent. Gill opening large, extending down to the fifteenth pectoral ray. Eye of medium size; 

 pupil small, circular. Nostril single, without tube or raised rim. 



Dorsal beginning above base of pectoral; dorsal and anal joined to caudal for 0.25 its length; 

 caudal slender of 8 rays; upper lobe of pectoral composed of 26 rays, lower lobe of 7 rays, the 4 upper 

 rays of lower lobe exserted, reaching vertical from a short distance behind gill slit. Disk small, under 

 posterior margin of eye. Vent close behind disk. 



Body and head stippled with dark brown angular dots; abdomen dark; in life faintly tinged with 

 light red. 



Careproctus opisthotremus, new species. (Fig. 23.) 



Type 50 mm. long, from station 4780 between Petrel Bank and Agattu Island, Bering Sea; depth 

 1,046 fathoms. 



Head 30 hundredths of length without caudal; depth 17.5; eye 5; snout 8; maxillary 13; gill 

 opening g; interocular width 9; width of head 16; depth of head 16; disk 8; distance disk to tip of
