A Contribution to the Knowledge of the 
Ichthyic Fauna of the Kansas Cretaceous.” 
BY ALBAN STEWART. 
With Plates L and II. 
Since the publication of Prof. Cope’s Cretaceous Vertebrata in 
1875, very little work has been done upon the Teleost fishes from 
the Kansas Cretaceous. During the time intervening since then 
four papers have appeared upon this Subclass, two in America by 
Cope}, {, and twoin Europe by Felix||, and Crook§, The last 
two have thrown much light upon the osteology of the forms 
treated, but only one new species was described, /chthyodectes 
polymicrodus Crook, which Cope thought to be a synonym of his 
I. arcuatus**, although this fact cannot be determined until a more 
complete description and a figure are made of’ the type of this 
species. The object of the present paper is to describe five new 
species from the Cretaceous of this state, with a few remarks upon 
the classification of the Saurodontidae, which I think are justifiable 
in the light of some new characters shown by the material in the 
Kansas University Museum. 
Family Saurodontide Cope 
Saurocephalide Zittel 
Ichthyodectid& Crook. 
Cope characterizes this family as embracing carnivorous fishes, 
many of large size, and as being the predominant type of fishes 
during the Cretaceous period of North America. He gives the 
following synopsist¥:
