external surface of the ear grizzled gray and black ; internal 

 surface thinly clothed with white hairs ; all the upper surface 

 mingled gray, reddish brown and black, distinct black fascia 

 being apparent on the lower part of the back and rump ; the 

 base of the fur on all the upper surface is black, succeeded 

 by fawn-white and tipped with dark brown ; the lengthened 

 hairs dispersed over the back are black for three-fourths of 

 their length and tipped with white ; throat and under surface 

 dull bufFy white, the base of the fur being deep gray ; arms 

 brownish white ; legs grizzled brown and fawn colour ; toes 

 covered with long glossy brown hair ; tail thinly clothed with 

 short brown hairs on the sides, a narrow line of black along 

 its upper surface gradually deepening as it approaches the 

 extremity, where the hairs lengthen and form a small tuft ; 

 under surface of the tail clothed with stiff dirty white hairs, 

 which increase in length as they approach the extremity. 



The female is so similar that a separate description is un- 

 necessary.

I cannot conclude without expressing my obligation to M. 

 Priess for the readiness with which he afforded me the use of 

 these valuable specimens for my "Monograph of the Macropo-

 the other novelties he has collected.
