196 NOKTH 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 fe^Y 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 Eed 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 211.6. tail vertebrae 63, hind foot 27.8. 



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



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

 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 Eesolution, and at Fort Rae, though I trapped 

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

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

 August 25. 



In 1903 Alfred E. Preble and Merritt Gary 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 

 aboA^e Pelican Rapid; Swift Current; La Biche River; and 30 miles 

 aboA^e Athabaska Landing. An adult male taken at La Biche RiA'er 

 on August 29 had assumed the fall pelage, Avas ver}^ fat, and in all 

 probabilit}^ would have hibernated soon. The species was last taken, 

 aboA'e Athabaska Landing, on September 11. The measurements of 

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

 tebrae 129, hind foot 29.3; tAvo from Fort Resolution aA^rage 216, 

 132, 31 ; four from the Athabaska aA^erage 220, 31.5, 30.7. These speci- 

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

 Bay region. 



Ross recorded sjDecimens from Portage La Loche ; » later he gaA^e 

 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). ^
