This description is from a single specimen brought by Mr. 

 Nuttall from beyond the Rocky Mountains. It was captured on 

 the banks of a small stream which flowed into the Snake or 

 Shoshone river, where it was not uncommon. We never heard of 

 it on the Columbia, and presume, therefore, that it does not 

 inhabit a very extended range. — Towns. 



Townsend's Shrew Mole.

 Sciences, vol. 8, part I. Scalops canadensis, (Richardson,)

" This species first described by Dr. Richardson, was incor- 

 rectly referred to the common shrew mole of the United States. 

 Its size and dentition are sufficient evidences of its being a new 

 and distinct species, which, on account of the number and ar- 

 rangement of its teeth, will either require the characters of the 

 genus to be enlarged, or that it be placed under a new subgenus. 

 A specimen of this quadruped was kindly presented to me, by 

 Mr. Nuttall, who requested, that in case it should prove a distinct 

 species, it might be given under the above name. I subsequently 

 received from Mr. Townsend another specimen, a little larger, 

 which I presume to be a mere variety, although very singularly 

 marked.

 of the United States. The whole upper and under surface is of a

 blown aside, exhibits a grayish-black color from the roots to near
