" The fur on the back is for three-fourths of its length from the 

 roots of a plumbeous color, then light ash, mixed with buff; and 

 the long interspersed hairs are all tipped with black. The ears are 

 pretty well clothed internally and externally with hairs of an ash 

 color, bordered with a line of black anteriorly, and edged with 

 white. From behind the ears to the back there is a very broad 

 patch of buff, and the same color, mixed with rufous, prevails on 

 the outer surface of the legs, extending to the thighs and 

 shoulders. The soles of the feet are yellowish-brown. The 

 claws, which are slightly arched, are light brown for three- 

 fourths of their length, and tipped with white. The under sur- 

 farce of the tail is white.
