1916] Merriam: Mammalian Remains from the Tejon Hills 



121 



A M- (figs. 8a to 8c) obtained by Mr. Pack from beds overlying 

 strata referred to San Pablo on the north side of Hospital Creek in 

 the foothills of the Mount Diablo Range southwest of Modesto shows 

 much the same width of crown and narrowness of fossettes as in M- 

 obtained by Mr. Pack at Ingram Creek several miles to the southeast, 



Figs. 8«, 8b, and 8c, Neohipparion, near gratum tehonense Merriam. M-, 

 natural size. Outer and occlusal views, and section at s near proximal end of 

 distal third. Fig. 8a outer view; 8&, cross-section at s; fig. 8c, occlusal view of 

 slightly worn tooth. Collected by E. W. Pack, of U. S. Geol. Survey, north side 

 of Hospital Creek, western border of San Joaquin Valley, California, at S.E. cor- 

 ner sec. 11, T 4 S, E 5 E, M. D. B. & M. 



Figs. 9a and 9b. Neohipparion, near molle Merriam. M 3 , natural size. Fig. 

 9a, inner view; 9ft, section at s near proximal end of distal third. Collected 

 by E. W. Pack, of U. S. Geol. Survey, one mile north of Ingram Creek, western 

 border of San Joaquin Valley, California. 



but the protocone is small and almost circular in cross-section. If 

 this specimen by any chance is shown to represent the same form as 

 the M^ from Ingram Creek there might be reason for considering the 

 possible identity of N. molle and the N. gratum group. For the pres- 

 ent there seems good reason for keeping the forms with wide proto- 

 cone separate from the group with narrow protocone.
