196 NORTH AMERICAN FAUNA. [no. 27. 



9 to 23, and later he collected the species at both Red Deer and Cal- 

 gary. In 1895 he reported it common at St. Albert, a few miles north- 

 west of Edmonton, and took a specimen there on October 30. This 

 was still in the dark, worn summer coat. Several specimens taken by 

 G. F. Dippie near Red Deer in April and May, 1900, are in the Bio- 

 logical Survey collection. Two of these are melanistic, being of a 

 nearly uniform sooty color throughout, only slightly lighter beneath. 

 The measurements of six specimens from Edmonton average: Total 

 length 214.6, tail vertebras 63, hind foot 27.8. 



Zapus hudsonius (Zimm.). Hudson Bay Jumping Mouse. 



During our trip in 1901 we did not detect this species until we 

 reached Fort Smith, where we took several in shrubby woods border- 

 ing a marsh. Here one afternoon I watched one for some time hop- 

 ping about in some willows near the edge of a marsh. He moved 

 quite leisurely, taking jumps of only 2 or 3 feet. Only two were 

 trapped at Fort Resolution, and at Fort Rae, though I trapped 

 carefully for them, I failed to capture any. During our return trip 

 we took two on the Athabaska, 60 miles above Grand Rapid, on 

 August 25. 



In 1903 Alfred E. Preble and Merritt Cary took one at Fort Reso- 

 lution in June, and while working on the Athabaska in the early 

 autumn trapped specimens at Fort McMurray; Brule Rapid; 25 miles 

 above Pelican Rapid; Swift Current; La Biche River; and 30 miles 

 above Athabaska Landing. An adult male taken at La Biche River 

 on August 29 had assumed the fall pelage, was very fat, and in all 

 probability would have hibernated soon. The species was last taken, 

 above Athabaska Landing, on September 11. The measurements of 

 three adults from Fort Smith average: Total length 210.6, tail ver- 

 tebrae 129, hind foot 29.3; two from Fort Resolution average 216, 

 132, 31 ; four from the Athabaska average 220, 31.5, 30.T. These speci- 

 mens are not separable from typical Z. hudsonius from the Hudson 

 Bay region. 



Ross recorded specimens from Portage La Loche ; a later he gave 

 the species as common there, and recorded it also from Fort Simpson.^ 

 I have recently recorded Z. hudsonius, on the strength of specimens in 

 the National Museum, from Fort Resolution' and Fort Rae.' 



MacFarlane reports this species, on the authority of P. Descham- 

 beault, as occurring at Isle a la Crosse and at Lac du Brochet post 

 (Reindeer Lake).' 1
