broad, covered with short hairs ; short black whiskers on the 

 cheeks, and similar hairs grow thinly distributed above and 

 below the eyes; throat dusky white ; upper fore-teeth short 

 and reddish-yellow ; lower fore-teeth twice the length of 

 the upper, and paler. Upper part of the body with short 

 hairs, dark at the base, in the middle dingy white, then 

 first black, next yellowish-white, and tipped with black, 

 the whole a variegated dark yellowish grey ; the hair on 

 the sides is longer, has less black, and is without the yel- 

 low tinge ; that on the belli/ is dark at the base and dingy- 

 white above; tail, to the end of the hair, five inches long, 

 with long hairs banded with black and white and tipped 

 with white, the whole appearing indistinctly striped with 

 black and white. Feet broadish ; toes thin and grey, co- 

 vered with hairs, on the fore-feet the second from the in- 

 side longest, the outer shortest and placed far back ; the 

 three centre hind-toes nearly of an equal length, the ex-

 on the fore-feet long and sharp, those on the hind- toes

This specimen approaches the A . pruinosa in some parts of 

 the description, but is still so distinct in others, that I cannot 

 suppose it to be a different state or age of that animal, or even 

 supposing imperfection or error to exist in the description of 

 A. pruinosa, that the two can be ever brought together as one 

 species. 



The name is given in compliment to the intrepid and spirited 

 Commander of the Expedition, to which, from his perseverance 

 in the arduous enterprise intrusted to his conduct, so much of 

 interest is attached.
