The Fauna of tlie Lower Division. — The lower John Day has 

 proved to be almost devoid of fossil remains, although careful 

 search was made for them at a number of localities. The follow- 

 ing forms are represented in the University of California 's 

 collections by fragmentary specimens too poor for specific de- 

 termination : 



41 Not calearatus but an undescribed species, Matthew, Bull. Am. Mus., 

 Vol. 16, p. 316. H. hesperius of Hay's catalogue, Bull. 179, U. S. G. S., 

 p. 675. 



42 The characters cited in the original description of this genus (Sinclair 

 1905) are, perhaps, insufficient to warrant separating it from Eypertragulus. 

 It is retained for the present, pending a revision of the group.
