SCO CLASS MAMMALIA. 



ing only on a sort of pulp, or hard excrescence, and upon 

 the exterior toe, which, contrary to the general rule, is the 

 largest ; the figure carefully represents this peculiarity ; 

 the others do not appear like toes, and the animal can 

 open them no farther than the point, where the nails 

 become perpendicular to the line of the fore-arm ; the hind 

 feet do not appear calculated for walking, and are very 

 ill formed — the sole is swelled, and the inner toe is the 

 shortest and weakest; the mouth is nothing more than 

 a small horizontal cleft at the end of the conical, or trum- 

 pet-formed, head ; its length from the tip of the nose to 

 the insertion of the tail, averages about four feet six inches ; 

 the ears are small, round, and large at the base ; the 

 eyes are small, imbedded, and without lashes or lids ; the 

 nostrils are large, of the figure of the letter C ; the tongue 

 is fleshy, very flexible, sharp, not altogether round, but 

 similar to the tongue of some birds, and the animal can 

 protrude it sixteen or eighteen inches ; the nails are gene- 

 rally bent, very powerful, and trenchant in the internal 

 part; a callous pulp, about two inches in height, and 

 almost entirely united to the fourth toe, but altogether 

 destitute of a nail, may be said to represent a fifth toe — 

 the animal treads on this in walking ; in the posterior part 

 of the palm of the fore feet is a callosity, against which 

 he supports the point of the largest nail in seizing and 

 holding, which last he persists in with incredible force and 

 effect : the sole of these feet is callous ; the hind feet have 

 five short toes a little inclined inward, the three middle are 

 of equal length, and the internal toe is shorter than the 

 external ; the nails of these feet are bluntish, but slightly 

 bent, and useless for the purpose of seizing. The bones 

 of the tail are flatted laterally, and diminish to a point at 

 the termination ; the whole tail is amply furnished with 

 very long hairs ; the animal generally carries it horizon- 

 tally with the long hairs trailing on the ground, but it
