Sexual Dimorphism. It is apparent in this species (Hubbs and Lagler, 23'- l^i 11) 

 and occurs in at least one proportion. The female proportionally has a longer snout 

 than the male, but this difference is not easily demonstrated because the snout-length/ 

 head-length ratio changes with size of individual. 



Color. General coloration darker than in L. osseus\ intervening spaces between 

 numerous dark spots also dark in some specimens, making such individuals appear
