is not sufficiently detailed to enable us to distin-

From the work first quoted we shall notice 

 those characters which are most permanent : " ears 

 short, rounded; front arcuated; the line of the 

 profile continued upon the snout, without any in- 

 dentation between the eyes ; eyes very small ; end 

 of the nose black ; sinus very distinct and pro- 

 found ; tail very short, concealed by the hair ; an- 

 terior feet, claws elongated, slender ; fingers with 

 five suboval naked tubercles, separated from the 

 palm, from each other, and from the base of the 

 claws, by dense hair ; palm, anterior half, naked, 

 transversely oval; base of the palm with a round- 

 ed naked tubercle, surrounded by the hair; pos- 

 terior feet with the sole naked; the nails moderate, 

 more arcuated and shorter than the anterior ones; 

 the nails do not in the least diminish in width at 

 the tip, but become smaller towards that part 

 only by diminishing from beneath ; lower surface 

 of the claws split so as to form a longitudinal 

 groove. 



" Length of the prepared specimen, five feet two 

 inches ; of the tail, exclusive of the hair, one inch 

 and three quarters." 



For interesting particulars concerning the hab- 

 its of this animal, I must refer to Lewis and 

 Clark's Voyage up the Missouri,
