DESCRIPTIONS OF TWO NEW PIKAS FROM 
WESTERN NORTH AMERICA. 
BY OUTRAM BANGS. 
I HAVE recently brought together and compared all the pikas 
from western North America in the Museum of Comparative 
Zoology at Cambridge and in the Bangs Collection. This series 
represents four well-marked forms, two of which I describe as 
new. 
One of these is Ochotona minimus (Lord), characterized by very 
dark brown coloring and lack of grayish or yellowish suffusion at 
any season. Of this species I have before me a large series from 
several places in the Cascade Mountains near Hope and Sumas, 
B. C., and from the Mount Baker Range. O. minimus seems to 
descend to lower altitudes than the other American forms. The 
specimens were taken at different dates from June 6 to November 
17, and there are examples in worn summer, and in long, full 
winter, pelage. 
Another form, which I describe as new, is from the Gold 
Range of British Columbia. It is related to O. minimus, but is 
smaller, rather paler in general coloration, and much more 
extensively suffused with rich tawny about head, neck and under 
parts. 
A third form is represented by three specimens from Mt. 
Inglesmaldie, Alberta, (near Banff), taken at 8000 feet altitude. 
This form is very different from any of the others of which I have 
specimens. It is a pale, hoary animal, without yellowish or
