 about 30 inches : head, shoulder, and upper part of 

 back, grey -brown, clear at first, and darkening 

 towards the back ; the rest of the body, tail, and 

 feet, brown-black ; often a white spot on the throat.

 United States. 



We made a drawing of another specimen noted 

 in the Mustelidce, without the locality whence we 

 obtained it, but named 



M. nigra. Sable Mink and Fisher Weasel. 

 Having the head and sides of the neck fine grey, 

 and the rest entirely deep black, with a cast of 

 brown ; total length about 26 inches. The deno- 

 mination does not agree with Pennant's Fisher, but 

 more with the Sable, excepting that the form of the 

 body, and of the tail, resembles that of a Mink, while 

 the ^ahle is like a Polecat, and the tail is shorter 

 and somewhat tufted.
