 ings of black, light brown, and white, scarcely two hairs being 

 uniform in color. In general, it may be said that the tail, when 

 examined without reference to individual hairs, is light ash at the 

 roots of the hair, then a broad, but not well defined, line of 

 light rufous, then dark brown, and tipped with rufous and smoke
