second, and fourth). This differs from the genus Sorex in which four 

 or five unicuspids are always visible when the skull is viewed laterally. 



Measurements. — External measurements of the Berwyn specimen are 

 as follows: Total length 86; tail 29; hind foot 9.5. The skull of this 

 specimen is crushed, but some cranial measurements of the type, as 

 given by Jackson (1928, p. 210) are: Condylobasal length of skull 

 13.0 ; cranial breadth 6.1 ; interorbital breadth 2.7 ; maxillary toothrow 

 4.1. 



Habitat and habits. — ^These rare shrews are little known. The type 

 specimen was dislodged from the decayed interior of a large fallen 

 log, and the specimen from Berwyn was found in the decayed heart 

 of a dead chestnut tree, cut from a dry hillside at some distance from 

 water.
