 lobe 1-1.5; of lower lobe 15; shortest ray in notch 4. 



Dorsal 53; anal 46; pectoral 28; caudal 8; pyloric caeca 19. 



Body elongate, moderately compressed. Head deeper than wide, 

 the sides vertical, the occiput flattened and gently convex, not swol- 

 len. Pupil large, nearly half diameter of eye. Snout short, deep, 

 bluntly rounded, slightly protruding beyond the premaxillaries; 

 jaws nearly equal; nostril in front of middle of eye or slightly higher, 

 with the rim a little raised. Teeth lanceolate, recurved, in broad 

 bands, about 13 oblique rows in the half 



of each jaw. Gill slit very narrow, en- _^,_, — ^v-^^\" 



tirely above base of pectoral. 



Anterior dorsal rays increasing gradu- 

 ally in length; caudal truncate, slender, 

 its connection with the anal equal to one- 

 third its length; last dorsal and anal 

 rays not shortened; pectoral notched, fig. i-.-rei.ative size and position of 

 the tip of upper lobe reaching a point vent and disk of careproctus ento- 

 midway between vent and anal origin. 



Disk moderate, oval, very deeply cupped, the anterior margin 

 crenulate but not lobed, a notch on each side separating it from pos- 

 terior margin. Vent near disk, separated from it by slightly more 

 than half length of disk. (Fig. 17.) 



Color pale, translucent, everywhere dusted with minute black 

 points, these less numerous and coarser on the abdomen; lips black- 

 ish; abdomen silvery, the peritoneum jet black. 



Coarse ''thumb tack" prickles scattered over top of head and on 

 body. 



Closely related to C. colletti, differing in the deeper body, the longer 

 more protruding snout, the lighter color, and the presence of pricldes. 



A badly mutilated specimen from station 4838, west of Tsuruga, 

 Sea of Japan, depth 144 fathoms, seems to belong to this species, 

 but its condition does not admit of positive iilentification.
