markable character in the dentition of both, rendered 
particularly obvious by the taste for grinning in which 
these animals are so prone to indulge, consists in the 
great breadth of the two middle incisors of the upper 
jaw. It is this character, which, together with the 
prominence of their canine teeth, produces that greater 
extension of muzzle on which their generic distinction 
has been chiefly founded. 
The present species seems, from its name, to have 
been regarded by naturalists as peculiarly a native of 
the east of Africa; and Hasselquist, who, it is but fair 
to presume, was well acquainted with the animals 
described by his great master Linneus, mentions it m 
his Travels as being found in Ethiopia, whence it was 
brought to Egypt. It would seem, however, that it is 
more usually imported into Europe, im common with 
the last species, from the western parts of that still 
very imperfectly investigated continent. Our specimen 
is in manners very like the foregoing, but is more quiet 
and less inclined to display its agility or its talent for 
making faces.
