246 THE GEOGRAPHY OF MAMMALS 



World we find the Magellanic Dog (Canis magellanicus), 

 which extends to the very farthest extremity of the 

 American continent, while in Southern Africa the Black- 

 backed Jackal (C. mesomelas) is met with in the vicinity 

 of Cape Town, and in Australia the Dingo, now only known 

 in a semi-domestic state, is found over the whole con- 

 tinent. But although, as we have shown, the genus Canis 

 is so widely spread over all parts of the earth, the in- 

 dividual species are in some cases confined to restricted 

 areas. Many well-known members of the genus — such as 

 the Wolf, the Common Fox, and the Jackal — have a very 

 wide distribution. But other species of Dog have limited 

 ranges, and not more than two or three of them are 

 usually met with in exactly the same district. Examples 

 of this restricted distribution are afforded by the Maned 

 Wolf (Canis jubata) of Brazil and Argentina, by the Corsac 

 (Canis corsac) of Central Asia, and by several of the 

 African Fennecs. But as a rule it may be taken that the 

 various species of Dogs are hardy animals with extended 

 areas of distribution. 



Besides the genus Canis, the Dog family contains 

 three other well-marked genera, each embracing but one 

 species. One of these, the Bush-dog (Icticyon venaticus), 

 is found only in Brazil and British Guiana, the two others, 

 the Hunting-dog (Lycaon pictus) and the Long-eared Fox 

 (Otocyon megalotis) are both peculiar to the Ethiopian 

 Region, where the Lycaon appears to have a considerable 

 range from north to south, but Otocyon is only known 

 from the Cape Colony.
