under surface pale (dull flesh color on fresh specimens) and the 

 end blackish; under surface of muzzle whitish. The absence of 

 a dark dorsal area is one of the characters by which this species 

 may usually be distinguished from richardsonii. A brown pelage 

 occurs in summer, the animal being near uniform dull chestnut 

 brown or hair brown with under parts slightly paler. Third uni- 

 cuspid tooth not smaller than the 4th, usually sHghtly larger; 

 rostrum and brain-case lower and unicuspids smaller than in S. 

 richardsonii. 

 Measurements — Total length, about 4.70 in. (120 mm.) ; tail vertebrae, 

 about 1.75 in. (44.4 mm.); hind foot, .55 in. (13.7 mm.). 

 So far as known the only specimen of the Smoky Shrew which has 

 yet been collected within our limits was taken at Racine, Wisconsin, 

 and is now in the National Museum collection. The specimen was 

 originally identified by Baird as S. richardsonii, but was later dis- 

 covered by Miller to be S. fumeus (Miller, /. c, p. 39). 



Very little is known regarding the species and only a general idea of 

 its distribution has been obtained from the widely scattered specimens 

 which have been taken. The habits of this Shrew probably differ but 

 little from those of allied species.

Type locality — Swamps of Santee River, South Carolina. 



Distribution — North and South Carolina, northern Georgia, Ten- 

 nessee and Kentucky to southern Illinois; limits of range unknown. 



Description — General color dull chestnut brown, approaching sepia 

 brown; under parts ashy gray, often washed with pale drab brown; 

 fur slate colored at base; upper surface of tail dark, under surface 

 pale; 3rd unicuspid tooth smaller than the 4th. 



Measurements — Total length, about 3.45 in. (87 mm.); tail vertebrse, 

 1.25 in. (32 mm.); hind foot, .43 in. (10.50 mm.). 



Remarks — Resembles Sorex personatus in coloration and size, although 

 the tail and hind foot are somewhat shorter. They may always 

 be distinguished by cranial and dental characters, the rostrum being 

 decidedly broader and the 3rd unicuspid tooth is smaller than the 

 4th (see illustration, p. 408).
