characters, but with peculiarities of dentition of a combined 
ruminant and suilline character. There was on the outer side of 
the molars but one crescent, and before this a tubercle. The inner 
portion of the crown a tedge. Besides the species Bathmodon 
radians, a second form, Loxolophodon semicinctus, was referred to 
the group. The former animal was large as the rhinoceros, the 
second equal to the tapir. 
Prof. Cope read a paper “ On two new species of Ornithosaurians 
from the Kansas cretaceous.” They were described as Ornitho- _ 
chirus umbrosus and O. harpyia. The former was regarded as one 
of the most gigantic of the Pterodactyles, extending probably 25 
feet from tip to tip of the wings. The other was two-thirds the 
size, ; 
Prof. Cope read a paper “On Protostega,” a genus of extinct 
Testudinata. A detailed account of the osteology of P. gigas from 
the cretaceous was given, by which it appeared that the genus had 
Separate ribs as in Sphargis, and that the carapace was formed 
by large radiating plates of bone in the skin. Two other species 
Were described — P. tuberosus and P. neptunus. The latter, the 
largest known marine turtle, from New Jersey; the former, from 
the cretaceous of Mississippi, had been referred by Leidy to the 
Mosasauroids, 
A discussion on Mr. Prices paper read at the last meeting 
took place, in which Prof. Hartshorne, Prof. Lesley, Mr. Price and 
_ Prof. Cope took part. Prof. Hartshorne supported the opposi- 
tion to Abiogenesis expressed in the paper, on the ground of insuf- 
ficiency of evidence in its favor, but believed in the evolution of 
Species. Prof. Lesley objected to the insufficiency of Mr. Price’s 
» Masoning against the labors of experts in biological science, and 
Stated that the more attention he paid to the subject, the better 
Satisfied he became that man was descended from apes. Prof. 
Cope Stated that Mr. Price’s paper was in error as to the facts:
