MAMMALOGY-, 



Mr. Brooks, as well as other preparations, it appears that tlie 

 animal could, if so disposed, almost, if not entirely, touch bis heel 

 with the ends of his fingers while standing erect ; in S. Pann the 

 hand reaches to the knee, and rather lower, for the animal, judging 

 by the skeleton, can cover the knee with the palm or hollow of its 

 hand. The reversed direction of the hair upon the arms in 

 S. Satyrus is not peculiar to that species, it is the same in both^ and 

 in both the haunches are covered with hair, but in S. Satyrus the 

 back of the hands is rather hairy, in the other bare. Besides that 

 the hair of one is black and the other ferruginous, that of the 

 Black kind is shorter, of a finer texture, and disposed more closely 

 on the body in the specimens of Simia Pann than in Simla Satyrus ; 

 but in this respect it is probable that both may vary at different 

 periods of their growth, or from some accidental causes^ such as a 

 different temperature of climate, or variation in the health of the 

 animaL The variation in this respect was considerable in Simia 

 Satyrus, which we saw in London in the year iSlS. On its first 

 arrival in England the hair was longer than it was sometime after- 

 wards, but the middle of the breast and belly, which was at first 

 naked, became hairy nearly about the same time that the other parts 

 of the fur had become shorter. We have observed also, that the 

 abdomen of the Black Oran-Outang (our Simia Pann and Simia 

 Satyrus of Linnaeus) is sometimes covered with hair, a circumstance 

 that renders the expression of Linn^us " aldomine ventricoso 

 glabro :" and dorso et humeris pilosis reliquo eoi*pore glahro " of 

 Blumenbach nugatory in characterizing the species, and which for 

 this reason is not mentioned in the specific character we have assign- 

 ed to it. While we are speaking of its fur we ought to observe that 

 it is shorter and somewhat more sparingly diffused in the specimen
