PRELIMINARY LIST OF THE MAMMALS OF NEW YORK 317 



Principal records. De Kay and Merriam : The statements by these 

 writers quoted under the northeastern white-footed mouse refer partly 

 to the present species. 



Mearns : "The Canadian deer mouse though nowhere abundant was 

 found from the margin of Schoharie creek up to the summit of Hunter 

 mountain and in all sorts of places — sugar camps, deserted houses, 

 deciduous woods, spruce and balsam swamps, under rocks, among the 

 roots of old stumps, in brush heaps, and in open grassy places; in short 

 it was found everywhere, but nowhere in abundance. It was much less 

 common than Peromyscus leucopus along Schoharie creek, where both 

 species were sometimes taken in the same spot. When trapped its 

 cheek pouches are as likely to be filled with food as those of the chip- 

 munk. I do not remember ever to have found food in those of 

 Peromyscus leucopus " ('98b, p. 350). 



This species is abundant at Peterboro, Madison co. and Elizabeth- 

 town, Essex co., but I have not met with it elsewhere in New York. In 

 both of these localities it is chiefly a forest mouse, seldom entering the 

 cleared land occupied by P. leucopus noveboracensis. In open groves and 

 about the outskirts of heavy woods the two species meet on neutral 

 ground, but in general their ranges are so distinct that it is possible after 

 a little experience to predict which animal will be caught in a particular 

 spot. In the original description of this mouse (Miller, '93b, p. 62) I 

 called attention to the fact, since verified by Dr Mearns, that the cheek 

 pouches are much more freely used by this species than by the north- 

 eastern white-footed mouse.

Faunal position. The cave rat is probably an inhabitant of the 

 transition zone, though its peculiar habits make any definite decision a 

 matter of uncertainty. It occurs in many localities within the limits of
