 Palaeomeryx borealis (Cope). 

 PlioplarcJius septemspinosus Cope. 



A number of these forms are not represented in the Univer- 

 sity of California collection and further exploration will be 

 necessary before the two faunas can be fully separated. 



Remains of the following species were collected by the Uni- 

 versity parties at localities where there can be little doubt of 

 their Mascall origin. A large amount of material is unfortu- 

 nately too fragmentary to permit of specific determination. 

 To this list there is added the type of Tephrocyon rurestris 

 (Condon), which is known to be from the Mascall beds.

53 Collected by Mr. L. S. Davis for Professor K. A. von Zittel from the 

 Mascall near Dayville. A part of the maxilla supporting P*. 



■"' 4 Astragali and ealcanea. Size of Alticamelus altus. 



55 The presence of a small Merycoidodont is indicated by a mandibular 

 fragment with the greater part of the milk dentition from the Mascall near 

 Dayville. A eaniuiform jjremolar was obtained from the Mascall beds on 

 the divide between Camp Creek and Crooked River. 



56 From the leaf-bearing beds of the lower part of the Mascall near the 

 old Van Horn ranch. A single species from this locality.
