lary spot, and slightly in form of the profile. The j^oung lack 

 this spot, and cannot readily be distinguished from the young of 

 Traehynotus rhomboides. It is therefore probable that all the 

 references made by authors lo the occurrence of T. rhomboides 

 (ovatus) on the Pacific Coast of Tropical America refer to this 

 species. A series brought b}^ Professor Gilbert from Panama 

 (now unfortunately destroyed) is said to render this view very 

 probable. We are informed by Professor Jordan that the specimens 

 brought by Professor Gilbert from Mazatlan, recorded as T, 

 rhodopus, belong to this species, of which the latter cannot be the 

 young, as was at first supposed.
