Relationships. — L. rhodosoma resembles L. ochotensis in most re- 

 spects, differing in the shape of the head and the coloration. These 

 two species inhabit the same geographical region, but up to the 

 present time all the specimens listed as L. rhodosoma are from greater 

 depths than any of the specimens of L. ochotensis. It seems unlikely 

 that L. rhodosoma represents a color phase of L. ochotensis. 



Description oj type. — Dorsal 45; anal 37; pectoral 41; pyloric coeca 

 37; depth of body 3.7; head 3.5. Eye 7 in head; disk 2.7.
