we have as yet discovered only very few traces of terrestrial 
animals which lived during the deposition of these important 
strata. Perhaps new zoological forms will be discovered there 
filling up the immense gap which exists between the J urassi¢

Prof. Leidy has founded a species of lion, Felis augustus, on sev- 
eral teeth and fragments of riots from the Loup Fork of the Nio- 
brara, Nebraska, obtained by Dr. Hayden. The most character- 
iscosaurus ; and “ viewing the specimen as probably represent 
ing a genus different from those mentioned, he proposes for the 
species the name Oligosimus grandevus.” Another specimen ob- 
tained by Dr. Hayden in the “ Black Foot country” at the es = 
the Missouri, “ looks as if it had formed part of the dermal a

Leidy. specimen here described is a fragment of an upper 
jaw with er molar teeth, and another a lower jaw with one molar. 
e upper molars have crowns composed of four lobes, the outer 
of which are like those of Anchitherium. The three upper molars 
occupied a space of eight lines. They are too large for the know? 
species of Hyopsodus or Microsyops, and nearly accord with the 
lower molars of Notharctus. The species is named Hipposyys

is were alleged Polyzoal [or Bryozoan] affinities, however, have 
some claim on our acceptance. Indeed, were it not for the dis-
