Remarks. Z. p. kootenayensis is a pale race of jumping mouse, of a 
somewhat bleached appearance, which apparently inhabits the more 
humid districts of the semi-arid region of southern British Columbia. 
Its habits are similar to those of other forms of the genus. It shows no 
sign of intergradation with Zapus trinotatus trinotatus of the western 
slopes of the Cascades. In the Columbia valley it was found at edge of 
mountain rills in shelter of heavy vegetation, false hellebore ( Veratrum 
viride Ait.), Delphinium , valerian ( Valeriana sp.), etc., whereas the Yahk 
specimen was taken under tall grass overhanging the edge of a dry channel 
of creek in open meadow. It is apparently as sensitive to cold as its con- 
geners, as the last specimen was taken on September 1, and no others 
were observed after the first sharp frosts. 
Thanks are due to officials of the United States Biological Survey 
for the privilege of examining large series of various forms of Zapus in their 
collections, and particularly to Mr. E. A. Preble for assistance in comparing 
specimens; also to curators of mammals in American Museum of Natural 
History, New York, and Philadelphia Academy of Natural Sciences, to 
Dr. E. Raymond Hall, curator of mammals in Museum of Vertebrate 
Zoology, University of California, for loan of specimens of his three new 
subspecies of Zapus prineeps from Great Basin region, and to Mr. Arthur 
Svihla, curator of The Charles P. Conner Museum, State College of Wash- 
ington, for loan of two Zapus specimens from states of Washington and 
Idaho.
