There is little to separate these two examples from 0. hexacornis, 

 save perhaps in the more compressed body, slightly notched second 

 dorsal of the male, more narrow interorbital space, and longer or 

 slender caudal peduncle. The coloration of 0. h. gilherti is perhaps 

 also paler in life as the examples are decidedly so at present, having 

 been in the same preservative. At any rate, I provisionally retain 

 them as distinct. 



(Named for Dr. Charles H. Gilbert, of the Chair in Zoology in the 

 Leland Stanford Junior University, whose valuable contributions 

 to ichthyology may easily be identified by their thorough excellence 

 and accm*acy of detail.)
