Evuryoris 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 vellerosus.
