 considerable value in designating species. For modification of char-

DISTRIBUTION 



The genus Careprodus is widely distributed, as is usual with deep- 

 water genera. It is represented in the moderately cold waters of the 

 north and south temperate regions and at greater depths inHhe 

 tropical Pacific. It has not been recorded from the tropical Atlantic 

 or the Indian Ocean but may reasonably be expected to be discovered 

 in these regions. 



The giant species of the genus, as is true of Liparis, are most 

 common in the North Pacific. The giant species and their distribu- 

 tion are as follows: C. ovigerum, 318 mm.; off British Columbia, 

 depth 1,588 fathoms; C. longipinnis , 270 mm., Arctic Ocean, depth 

 702 fathoms, C. trachysoma, 263 mm., Japan Sea, depth 318 fathoms; 

 C. cypselurus, 260 mm., coast of Washington to Okhotsk Sea, depth 

 510-887 fathoms; C. coUetti, 248 mm.. Gulf of Alaska to Okhotsk 

 Sea, depth 284-629 fathoms; C. rastrinus, 280 mm., Okhotsk Sea, 

 depth 73-119 fathoms. Two species, C. cypselurus and C. colletti, 

 range from the American to the Asiatic coast, but the largest specimens
