(139-152) ; tail vertebrae 30 (23-36) ; hind foot 19.5 (18-20). He gives 

 some measurements of the skulls of 10 adult males from Magnetic 

 City as follows: Greatest length 32.4 (31-33.8); mastoidal breadth 

 14.5 (13.9-15) ; interorbital breadth 7.3 (7.1-7.5) ; maxillary toothrow 

 9.9 (9.2-10.2) . Females average smaller than males. 



A male (probably immature) from Vale Summit Road, between 

 Clarysville and Vale Summit, Allegany County, has the following 

 external measurements: total length 136; tail 22; hind foot 16. This 

 animal weighed 35.7 grams. 



Habitat and habits. — In Maryland this mole is found only at high 

 elevations in the western part of the State, where it lives in loose 

 well-drained light soils. It may be found in pastureland, as well as 

 in the deep woods, but is seldom encountered in damp areas or in clay 

 soils. Although the eastern mole {Scalo]ms aquaticm) also occurs in 

 western Maryland, it appears to be ecologically or at least altitudin- 

 ally separated from the hairy-tailed mole. The eastern mole has been 

 taken in the lowlands ; the hairy-tail only at higher elevations. 



This species makes irregular subsurface runways which form an 

 elaborate network. In the winter these tunnels are deep so as to avoid 

 the freezing temperatures of the upper layers of earth. Nests are con- 

 structed in these deep burrows, some 10 to 20 inches below the surface 

 of the ground. These are made of dried grasses and leaves, and are 

 some 6 inches in circumference.
