This individual, which I have compared with topotypes of Evofomys 
gapperi rhoadsi in the departm ent of agriculture collection, appears to 
be of this form. The specimen (No. 82,832 U.S. N. M.) shows very 
little of the red dorsal area, the back being brownish gray as described 
by Mr Stone and quite unlike any of the Catskill specimens” (’98b, 
P- 350). 
Remarks. This record appears to me open to serious question, though 
under the circumstances I see no other course than to include it as it 
stands.

Type locality. Mount Washington, New Hampshire. 
Faunal position. The rock vole is so slightly known that its faunal 
position can not now be definitely stated. Apparently it is a member 
of the Hudsonian fauna, reaching the Canadian zone in the coldest 
situations only. 
Habitat, Damp, heavy spruce woods in the Hudsonian zone (Allen, 
’gaa, p. 102, Bangs, ’96b, p. 49), cold rock cavities in the Canadian 
zone (Miller, ’94, p. 192-93, Batchelder, ’96a, p. 188). Batchelder 
thus describes the habitat of this animal at Beedes, Essex co., New 
York: “This place was a steep hillside heavily wooded with an old 
mixed growth. The lower slopes were made up of a talus of large 
angular blocks of rock piled one upon another as they had fallen from 
the cliffs above. The damp rocks were covered with sphagnum and 
ferns, and from the holes and spaces between them came currents of 
cold air, indicating the presence of masses of yet unmelted ice somewhere 
in the depths below. . . . I trapped for two days at the foot of another 
talus ... Here the huge rocks gave little foothold for the large trees, 
but the masses of ice beneath, of which glimpses could be had here and 
there, in the caverns between the rocks, aided by the shade afforded by a 
wall of mountain, produced a temperature so low that spring flowers 
blossomed even in August among the deep beds of damp sphagnum that 
coveretl the rocks” (’96a, p. 188). 
Distribution in New York. The rock vole has been found at only 
two localities in New York, at Beedes, Essex co. and on Hunter mountain 
in the Catskills. It probably occurs among the mountains of the
