sent unique, and the skull and teeth cannot easily be examined 

 without risk of deterioration, I can make no remarks on those 

 organs. I have only to add, then, that the specimen is a skin of a 

 female, apparently adult, and, like most if not all of the skins 

 obtained during the expedition, very beautifully prepared.
