FAMILY MUSTELID^E. 35 



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 in its 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 given this a careful examination, and distinguished it 

 as a new species. We adopt his name.

 nose dark brown ; a white spot on the head, and a band above the eyes. Whole length 18 inches ;
