[Plate I.] 



The remains of fishes closely related to the living Amia calva were 

 recorded by Prof. 0. C. Marsh ^ in the year 1871 from Tertiary 

 strata in Wyoming (U. S. A.). These remains were thought to belong 

 to two species, both about the size of their living representative. 



In 1873 Leidy^ described and figured several vertebrae from 

 the Bridger Beds of Wyoming which seemed to him to be allied to, 

 but generically distinct from, Amia calva ; for these he proposed 

 the two generic names of Protamia and Hypamia, the former 

 including three species and the latter one. 



In the same year Cope^ described from the same locality, but 

 without figures, a number of vertebrae with associated jaws and 

 cranial bones ; these he referred to five species, and included them 

 in one genus, which he named Pafpichthys. Two species of Amia 

 were described by the same author "* from Eocene shales of Elorissant, 

 Southern Colorado, and two ' from Miocene beds, Cypress Hills, N. W. 

 Territory (Canada). Subsequently Cope^ redescribed and figured
