CLETHRIONOMYS CAROLINENSIS (Merriam): Carolina Red-backed 

 Mouse, or Wood Vole 



The recorded occurrences of this red-backed mouse are all in the 

 eastern mountainous portions of the State. The vertical range here 

 extends from about 3,000 to 6,500 feet. In the Holston Mountains 

 northeast of Shady Valley these mice were trapped in the moss cov- 

 ering the roots of trees and rotten logs in hemlock timber. On Roan 

 Mountain, Mount Guyot, Old Black Mountain, and Inadu Knob red- 

 backed mice were caught in traps set in clumps of moss around roots 

 of balsam fir. Rhoads (1896, p. 186) writes, "Contrary to my expec- 

 tations, the wood vole of Roan Mountain was not found in wet places 

 but seemed to prefer rather open runways among the fallen logs, 

 moss and ferns on the borders of the forest * * *. Such situa- 

 tions were preferred to the depths of the forest, owing to the variety 

 of edible grasses and weeds only found in clearings." Red-backed 

 mice were trapped by Komarek and Komarek (1938, p. 157) in the 

 humid forests as well as around isolated shrubs on the grassy balds 

 at elevations above 3,000 feet. They list specimens from the follow- 

 ing localities in Sevier County : Buck Fork and Chapman Prong of 

 Little Pigeon River and Mount Guyot. It was also taken in Blount 

 County at Spence Field, a grassy bald located about 1 mile west 

 of Thunderhead Mountain.

MICROTUS PENNSYLVANICUS PENNSYLVANICUS (Ord): 

 Pennsylvania Meadow Mouse, or Vole 



There are no specimens of this vole from Tennessee in the National 

 Museum collection. Rhoads (1896, p. 185) stated that he felt justi- 

 fied in including this mouse among the mammals listed for Tennessee 

 since "on the summit of Roan Mountain two specimens of the meadow 

 vole were secured in a little 'bulrush' swamp below Cloudland hotel, 

 about 100 yards from the Tennessee line in Mitchell County, N. Caro- 

 lina." Furthermore, runways similar "to those in which the Mitchell 

 County specimens were taken were observed in swampy ground near 

 the summit of the mountain in Carter County, Tennessee, during my 

 ascent thither from the Doe River ravine." Perrygo trapped without 

 success at this same locality from September 14 to 22, 1937.
