and Zorilla of the Cape do not differ from those of the 
north of Africa, but by deeper colours ; the Genette of 
the Cape (Viverra Genetta et Felina^) inhabits also Spain; 
but it is replaced in Senegal and Abyssinia, by a local va- 
riety remarkable for its very pale hue (Viverra Senegalen- 
sis) ; the Ichneumon of Egypt (Herpestes Ichneumon) is 
replaced at the southern extremity of Africa by a local va- 
riety with a darker fur (Herpestes Cafer et Griseus) ; the 
same is the case with Ichneumon versicolor of Abyssinia, 
which has tints less clear than at the Cape of Good Hope. 
The Antilope mergens of the Cape is represented in Sene- 
gambia by Ant. grimmea, and in Abyssinia by Ant. Ma- 
daqua (Rupp. Neue Wirbelth.^ p. 7, fig. 1) ; the Antilope 
oreotragus or Lalandei of the Cape, by the Ant. redunca 
of Senegal and Abyssinia ; the Ourilibi (Antil. montana) 
of Abyssinia shews slight differences from the Antelope of 
the Cape (Antil. scoparia), and is the same as the Oryx of the 
former country (Ant. Beisa, Rupp.), which forms a race 
distinguished by a different disposition of colours from that 
of Ashantee and of the Cape. It sometimes even happens, 
that there exist, in each region of which I am treating, 
races representing the same species as the Antilops sylva- 
tica, scripta, and decula, which are mutually represented 
at the Cape, at Senegal, and in Abyssinia ; as the Ant. 
Mhorr of Barbary, there replaces Ant. Hama, of which the 
real country is Kordofan, Nubia, &c. Other animals, in 
fine, vary in these diverse places, in a manner so peculiar as 
perhaps to merit elevation to the rank of species :f such, 
for example, are the Phascochoerus ^liani, which represents 
in Abyssinia the Phasco. communis of the Coast of Guinea 
and the Cape ; also the Sciurus rutilans, the representa- 
tive in Eastern Africa of the Sciurus setosus of the Cape 
and Senegal, and several others. Facts analogous to these 
we have given are remarked in the classes of Birds and of 
Reptiles ; but fearing to give too great an extent to my 
work, I shall confine myself in what follows to the classes of 
^ The difference between these two mammifera is reduced to a shade 
in their colour, which appears to me purely periodic. 
t The Hyaena villosa of the Cape differs not from H. striata, except 
in its long and tufted fur, and its deeper colours.
