434 SOUTH AMERICAN WEESEL. 



Opossum iii most particulars, except in the appear- 

 ance of the tail. 



The following obscure and somewhat uncertain 

 species of this numerous genus,, seem scarce suf- 

 ficiently known to justify a decided specific cha- 

 racter for each, I shall, therefore, merely men- 

 tion them in as few words as possible. 



GREY-HEADED WEESEL. 



La Grande Marte de Guiane. Buff, suppl. 7. p. 250. pi. 60. 



THIS is black, with the head and sides of the 

 neck greyish ; and the throat and under side of 

 the neck white. It measures above two feet from 

 nose to tail, which measures eighteen inches. It 

 is a native of Guiana. 



SOUTH AMERICAN WEESEL. 

 La Fouine de la Guiane. Buff, suppl. 3. p. i6i.pl. 23. 



THIS measures from nose to tail twenty-one 

 inches and a half, and has a general resemblance 

 to a Polecat, but the tail is rather shorter in pro- 

 portion : the nose is long and sharp, and with the 

 cheeks, throat, and sides of the neck, black : the 

 forehead and sides of the head, to the ears, white : 

 the ears short, round, and edged with white.
