500 General Notes. ‘[ August, 
Recent PALHONTOLOGICAL DISCOVERIES IN THE West. — Prof. 
O. C. Marsh contributes to the July number of the American Journal of 
Science and Arts, the results of his studies of the Coryphodontide, a 
family comprising the oldest known tertiary mammals, the fossil bones 
coming from the base of the Eocene formation of Utah, Wyoming, and 
New Mexico. Ooryphodon was an Ungulate and among the mammals 
associated with it were “the equine Hohippus, and the suilline Helo- 
hyus, showing clearly that we must look to Cretaceous strata at least for 
the parent form of the Ungulates.”. The paper is accompanied by fig- 
ures of the skull of Coryphodon, and the feet bones of Coryphodon and 
Dinoceras. 
(Fie. 84.) RESTORATION OF (about one tenth natural size). 
The accompanying illustration is a restoration of Hesperornis T egalis, 
about one tenth of the natural size. It is a cretaceous bird with teeth, 
and Professor Marsh on fresh examination finds some additional charac- 
ters of importance of the order Odontornithes, of which it is a type- He 
also describes a new species of small swimming bird, which comes from 
the same geological horizon (cretaceous) and has been called by a 
Baptornis advenus. An enormous Dinosaur (Titanosaurus montanus) 
is also described as new from the cretaceous deposits of Colorado.
