the genus, is greater or less in the different species, 
as the figures evince. 
The hyaenas have only four teats, which are all 
abdominal ; in the dogs there are four abdominal, 
and two or four pectoral. 
And lastly, the hyaenas have a deep glandular 
pouch under the anus, like some of the viverrae and 
a few other animals, which the dogs have not. 
These differences are so great, as to be more pro- 
perly generic than specific ; and fully warrant the 
separation of the hyaenas into a distinct genus, 
which must be placed next to the cats, if the cha- 
racter of the teeth be followed, because, like them, 
they have no proper molar cheek-teeth, and because 
next to them, they seem the most perfectly fitted for 
carnivorous habits. 
The hyaenas, nevertheless, certainly approach the 
general character of the dog; and, following the 
fells juhata, and the fells venatlca^ they appear to 
form one of those natural transitions, frequently ob- 
servable between all the genera, from the felinse to 
the canine race. 
This genus may be considered as proper to 
Africa, although the striped species appears to have 
emigrated to some neighbouring parts of Asia ; and 
it is remarkable, that though the known parts of the 
former continent contain exclusively some animals 
which are not elsewhere to be found, they are, never- 
theless, observed not to produce such varieties, of 
* As the Camelopardalis of Linnaeus, the myrmecophaga capensis 
of Pallas, the dipus cqfer of Gmelin, and the hyaenas.
