460 C. H. Merriam — Fauna of Great Smoky Mountains. 



Evotomys Carolinensis, sp. nov. 



Type 3660, $ adult, Merriam Collection. From Roan 

 Mountain, North Carolina (altitude 6000 feet), August 11, 

 1887. C. H. M. 



Description of ty])e. — Size much larger than that of any 

 other known representative of the genus. The following 

 measurements were taken in the flesh : total length 164 mm ; 

 head and body lll mm ; nose to eye 13 mm ; to center of pupil 

 15 mm ; nose to occiput 29 mm ; tail vertebrae 44 mm ; pencil 7 mm ; 

 fore foot 1 3 mm ; hind foot 21 mm ; fore leg 26 mm ; hind leg 37 mm ; 

 height of ear from crown H 11 ™ • distance between eyes 9 mm ; 

 Ears large, suborbicular, prominent ; superior margin much in- 

 curved but not inflexed ; superior root considerably anterior to 

 plane of meatus ; antitragus large, its anterior root curving up- 

 ward in front of meatus and almost reaching the superior root 

 of the auricle. Tail long and slender, tapering from base to 

 tip ; not sharply bicolor, though paler below than above. 

 Whiskers black and white, reaching little beyond tips of ears. 

 Hind feet very large, and as broad as in Arctic rutilus, though 

 by no means so densely haired ; dark, with whitish hairs about 

 the nails ; posterior third of soles well haired. 



Upper parts dark, with a liberal admixture of black-tipped 

 hairs (agreeing in this respect with specimens of E. Gapperi 

 from the upper Red River Valley); dorsal stripe dull chestnut 

 and very broad, spreading out laterally and almost fading in- 

 sensibly into the fulvous suffusion of the sides (in all the other 

 known forms the dorsal stripe is sharply defined laterally). 

 Sides bister, strongly suffused with light fulvous all the way 

 from the cheeks to the thighs. Color of sides reaching down 

 so far as to seem to encroach on the whitish of the belly, com- 

 pletely enveloping the legs. The belly is strongly washed with 

 ochraceous. 



Description of other specimens. — A number of specimens 

 from Highlands, 1ST. C, collected in February, March, and 

 April, agree with the above in all essential respects. The line 

 separating the color of the sides from that of the belly is always 

 distinct and sometimes sharply defined (as in Nos. 2057 $ , and 

 2314 5 ). The plumbeous basal portion of the fur shows through 

 on the throat but not on the belly, where it is usually entirely 

 obscured by the whitish apical portion. The ochraceous wash 

 is strongest on the middle of the belly. The tail varies in length 

 in the dry skins from 44 mm to 58 mIn , but these measurements 

 must be regarded as approximate only, owing to possible dis- 

 tortion in preparing the specimens. It is always bicolor with a 

 distinct line of demarcation, though the under surface is never 

 white. The average length of the hind foot in six dry skins is 

 19'5 mm .
