PRELIMINARY LIST OF THE MAMMALS OF NEW YORK 



3*5 



of Oneida, Madison co. writes me, under date of February 3, i898 r 

 that he first saw the brown rat when his family moved to Oneida valley 

 in 1837. Previously the Wilsons had lived near Peterboro (about 12 

 miles distant), where only the black rat occurred.

 zone. 



Habitat. Dry, open woods, thickets, fields, outbuildings and occasion-

Distribution in New York. The northeastern white-footed mouse 

 occurs throughout New York state except in the boreal area occupied by

 by Rhoads ('97a, p. 27), but I am not satisfied that this is actually die 

 case. 



Principal records. De Kay: " The jumping [ = white-footed] mouse is 

 found in every part of the state, and is said to build its nest in trees " 

 ('42, p. 83). Merriam : " The white-footed mouse is common in all parts 

 of the Adirondacks " ('84d, p. 165). Fisher: "Common [at Sing Sing].

 rows, and in fall and winter ventures to the stacks and out-houses" 

 ('96, p. 197-98). Mearns: "This beautiful mouse was rather abun-
