Three specimens of this very distinct new species were brought 

 from the Columbia river by Mr. John K. Townsend, where he 

 procured them on his late journey. It is very like the P. Le- 

 contii, but they may be readily known by the color of the under 

 part of the body, besides which they differ in almost all their 

 details of color and proportions, the present being a larger and 

 more robust animal. Together, they seem to form a small group 

 in the genus, characterized by the double fleshy crest of the 

 nose, which is not mentioned as occurring in any other species. 



Verpertilio megalotis, (Rat.) Plecotis Rafinesquii, (Lesson,) 

 which is described as having the auricle as long as the ears, can- 

 not be either of our species. I am not acquainted with any 

 other species within the United States." 



Inhabits the Columbia river district, rather common. Fre- 

 quents the store houses attached to the forts, seldom emerging 

 from them even at night. This, and a species of Verpertilio, 

 (V. subulatus,) which is even more numerous, are protected by 

 the gentlemen of the Hudsfm's Bay Company, for their services 

 in destroying the dermestes which abound in their fur establish- 

 ments. — Towns. 



Townsend's Hare. 



Lepus *Townsendii, (Bachman.) Journal Acad. Nat. Sci- 

 ences. Vol. 8, part I., figure. Poolalik of the Walla-walla 

 and Nez Perces Indians. 



" This species, which is another of the discoveries of Mr. 

 Townsend, and of which no specimen exists in any museum that 

 I have had an opportunity of examining, is one of the most sin- 

 gular hares that has fallen under my notice.
