SMALL MAMMALS COLLECTED IN CANADA. 297 



They have practically the same habits as the Grey Gopher, but 

 usually only two live in each hole. 



S.franklini (Grey Squirrel). — Not very plentiful. Burrowing 

 animal, inhabiting bush country. Pair of old ones and family 

 live together. They appear to me to hybernate earlier in fall, 

 and come out later in spring than the other Gophers. First 

 seen in spring, 1902, on April 29th. 



Thomomys borealis (Pouched Gopher ; locally called Mole). — 

 Very common. My specimens were all trapped underground. 

 Habits appear to be much like those of English Mole. Last 

 seen in fall, 1901, at beginning of October. First seen in spring, 

 1902, on February 9th ; but they evidently work during the winter, 

 between the snow and earth, as their arched runs can be seen in 

 the grass when the snow thaws. The Indians have an idea that 

 their cheek-pouches are inflated with air, and then compressed 

 to force up their earth mounds. 



Tamias quadrivittatus (Chipmunk). — Not very plentiful. 

 They are easily caught. Best bait, almond. If fed while still 

 wild, they soon become tame enough to run in and out of the house. 

 The first I saw, in spring, 1902 (caught April 13th), had barley 

 in cheek-pouches, and was quite a quarter of a mile from nearest 

 barley-field or granary, so evidently had a winter store. 



Lasiurus cinereus and L. borealis (Bats). — Very few about. I 

 only obtained one of each species, both being taken by hand 

 while hanging in poplar trees during the daytime. The Indians 

 call them little birds with bare wings. 



Mus musculus (House-Mouse). — Not very plentiful, but 

 seems to be evenly distributed over both prairie and bush. This 

 appears to be the only very small animal which is constantly 

 about during the coldest weather. 



Zapus hudsonius (Jumping Mouse). — Not very common. 

 Frequents very high grass in swampy places. I could never 

 secure one in a trap, although I tried all sorts of baits and traps. 

 Those I did catch were taken by hand, whilst following mowing- 

 machine when cutting hay. 



Sorex richardsoni (Shrew). — I only saw and caught one. Bait, 

 cheese. 



Onychomys leucogaster (Short-tailed Mouse). — Bare. I under- 

 stand this has not been previously reported as taken in Canada.
