We know very little about the food habits of pocket-miee. 

 Seed of the desert plants, no doubt, are the principal food. 



Perognaihus fasciatus infraluteus has only been taken at the 

 type locality, which is about 8 miles northeast of Loveland, Lari- 

 mer Count}^ Colorado. It was taken in 1892 by Wm. G. Smith, an 

 eccentric English naturalist, and donated to the British Museum. 

 It was described in 1893 by Thomas as new. In 1894, members 

 of the Biological Survey took several specimens at or near the type 

 locality. At the time these specimens were taken, this section was 

 desert land, but now it has been brought under cultivation, and 

 as pocket-mice are a desert-loving species, it is doubtful if more 

 specimens can be secured from the type locality.
