FAMILY MUSTELINE.

We suppose this to be the Common Weasel of Richardson, which he states to be identical 
with the Common Weasel of Europe. It is, however, generically different, and we have 
been consequently compelled to suggest a distinctive name. Godman, Vol. 1 , p. 193, asserts, 
on the authority of Charles Bonaparte, that the Ermine, in its summer coat, has been usually 
considered by naturalists as the M. vulgaris of Europe. This is a mistake : it is the present 
species which has thus been confounded. 
It is by no means a rare animal, but is difficult to capture, and is usually known under the 
name of the Little Weasel. It feeds on mice, insects, young birds, eggs, etc., and possesses 
all the voracity characteristic of the tribe.

In the State Collection is a specimen of this animal, upon which I made, in 1840, two years 
since, the following note : “ Taken in May, in Suffolk county ; differs from pusilla units legs, 
“ which are very robust, and covered with long hair. It resembles noveboracensis in its 
“ markings; allied to vulgaris of Richardson, (excl. syn.), but his species has slender feet. 
“ We wait for more extended opportunities of comparison, before considering it a new 
“ species.” 
Recently, Bachman, (Op. cit.) has gi\en this a careful examination, and distinguished it 
as a new species. We adopt his name.
