 a. Adult : skeleton. Isle de France. From Mr. Gerrard's Collection. 



The comparison of the skeleton of this species with that of O. ben- 

 galemis proves the real difference of both species. The general 

 structure of the skeleton is much the same ; but, besides the difference 

 in the number of the fins and of the vertebrae, the frontal bones are 

 much broader, especially behind, where they form a conspicuous flat 

 vault : the distance between the orbits is larger than one-half of the 

 horizontal diameter of the osseous orbit, the same distance in G. hen- 

 galensis being smaller than one-half of that diameter. The first 

 interhaemal spine is equal to the length of the second to the seventh 

 vertebra, and is attached to the twelfth and thirteenth.
