16 Specimens: 15 Rose Station, near Fort Tejon (topo- 

 types), 1 Neenach. 



"In the San Joaquin Valley this pocket-mouse occurs very 

 abundantly in the grass-fields and dry plains. A few were 

 secured at the base of the Tehachapi Mountains, at the mouth 

 of the Canada de las Uvas, but they apparently do not extend 

 into the mountains as far as Fort Tejon, where only P. p. bangsi 

 was secured. The pouches of most of the specimens taken 

 contained the seeds of alfileria, EroJium." The young adult of 

 this species is of quite a different color, and much darker and 

 more olivaceous." 



Perognathus pericalles. 



Perognathus pericalles Elliot, Pub. Field Columb. Mus., HI, 

 1903, p. 252. 



2 Specimens from Keeler. 



This beautiful little species was evidently quite rare, as the 

 two examples secured were the only ones seen. It shows to a 

 remarkable degree the influence exerted upon color that the 

 neighborhood of Owens Lake exerts in producing the rich, deep 

 cream buff hue of its pelage. It was found among the sand 

 dunes at the edge of the lake, to which it appeared to be 

 restricted. 



Perognathus* elibatus.

9 Specimens from Lock wood Valley, Mt. Pinos. 



This is a dark species, and was abundant in the locality in 

 which the examples were taken, at an elevation of 5.500 feet, 

 "on the eastern slope of Mt. Pinos in the Pinon Belt. It was 

 found on gravelly soil supporting sage-brush, scrub-oaks, and 

 pinon pines." 



Perognathus monticola olivaceus.

6 Examples from the summit of the Inyo Mountains, east of 

 Lone Pine. 



I refer these specimens to the present race, although they 

 are not by any means "bright cinnamon buff," as given by
