anal scarcel}^ behind end of first dorsal. Pectoral 2.6 in head (in 

 a paratype), inserted below first dorsal. Outer ventral ray scarcely 

 filamentous, just reaching anus, 1.33 in orbit; ventral inserted 

 anterior to end of opercle. 



Anus less removed from anal than usual in the group of genera 

 to which Cetomirus belongs; distance from center of anus to origin 

 of anal one-third its distance from base of outer ventral ray; dis- 

 tance from ventral to isthmus equal to length of orbit. A naked 

 area, two-fifths as long as orbit, surrounding anus, and extending 

 to anal fin ; no other naked areas on breast. 



Color of body light brown, shading into blackish on belly; head 

 grayish; opercles, lips, and mandibles dusky; gular and branch- 

 iostegal membranes black; lining of buccal and branchial cavities 

 black, without light margins; peritoneum black. 



Four paratypes from Albatross station 4971, at which the type 

 was dredged, and one small paratype from station 4973, near the 

 type locality at a depth of 600 fathoms. 



Tabic of mcasumnenfs in hundredths of length to anus.
