212 ON THE GEOGRAnilCAL 



and Zorilla of the Cape do not differ from those of the 

 north of Africa, but by deeper colovirs ; the Genette of 

 the Cape (Viverra Genetta et Felina*) inhabits also Spain ; 

 but it is re^Dlaced in Senegal and Abyssinia, by a local va- 

 riety remarkable for its very pale hue (Viverra Senegalen- 

 sis) ; the Ichneumon of Egypt (Ilerpestes Ichneumon) is 

 replaced at the southern extremity of Africa by a local va- 

 riety with a darker fur (Ilerpestes 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- 

 C^ambia by Ant. grimmea, and in Abyssinia by Ant. Ma- 

 da([ua (Riipp. Neue Wirhclth., p. 7, tig. 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, lliirp.), whicli 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. Dama, 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 iEliani, which represents 

 in Abj-^ssinia the Phasco. communis of the Coast of Guinea 

 and the Cape ; also the Sciurus rutilans, the representa- 

 tive in Easteni 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 w^hat follows to the classes of 



* The difference between these two mamraifera 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.
