PRELIMINARY LIST OF THE MAMMALS OF NEW YORK 315 
of Oneida, Madison co. writes me, under date of February 3, 1808, 
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- 
ally houses. 
Distribution in New York. ‘The northeastern white-footed mouse 
occurs throughout New York state except in the boreal area occupied by
