EURYOTIS IRRORATA, Sp. nOV. 



" Rat from the Camaroon Mountains, 7000 feet above the level 

 of the sea. January 1862." 



I am not certain about this species until I can compare the skull 

 with those of the other species of the genus from Africa, as they are 

 all very similar externally. 



With these animals was sent the skin of a Chimpanzee without 

 its skull, but with the bones of the hand and feet enclosed in the 

 skin. This skin differs from all the other specimens of this species 

 which I have seen, in being covered with much more abundant and 

 softer fur, and in the fur of the back being of a brown colour from 

 the large brown tips to the blackish hair. It would seem to indicate 

 a distinct variety or species, which may be designated, until we re- 

 ceive better specimens and more particulars, Troglodytes veUerosus.
