Larger than either of the foregoing ; upward of 3 inches long, with the 

 tail averaging 3|, thus much exceeding the head and body, as in O. longl- 

 cauda, but feet much larger than in that species, 0.70 to 0.80 (whereas the 

 feet of longicauda are barely larger than those of humilis, very seldom touch- 

 ing 0.70). Upper parts a rather warm mouse-brown (rufous or dull ferrugine- 

 ous, not mouse-gray), which on the sides usually grows brighter, and is 

 sometimes almost orange-brown ; this, again, fading on the under parts into 

 a muddy-whitish (not white at all). Tail extremely scant-haired, nearly as 

 naked as in Mus rrmsculus, in dried specimens appearing nearly unicolor; 

 in alcoholic ones, dull pale brown above and whitish underneath. Hands and 

 fei't whitish above (like the tail underneath).
