posterior gular region ; anterior gular region and chin nearly white, 

 lightest anteriorly ; tail unicolor." 



By a comparison of the two descriptions, it will be seen that the 

 principal difference in color is in the lighter hue of the lower surface 

 of the body and tail in Mr. Richardson's specimen ; but if his was, as 

 his remarks imply, taken in the winter, and Mr. Cope's in summer, 

 this difference would fall within the variation according to season 

 known among other species of shrews. The specimen from War- 

 wick, though ashy brown beneath, has the tips of the fur hoary, and 

 the under surface of the tail light ash, — much Ughter than the upper 

 surface. In other respects the color agrees very well with Mr. 

 Cope's description. It was, also, taken at about the same season. 



Admitting the correctness of my identification of this species, the 

 known representatives of the genus Neosorex, which is, as yet, known 

 only in North America, wiU be as follows : —
