322 NEW YORK STATE MUSEUM 



This individual, which I have compared with topotypes of Evotomys 

 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- 35°)- 



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, 

 '94a, 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 

 covered 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
