182 ZOOLOGICAL GEOGRAPHY. [part hi. 



Western America, but the remaining genera, six in number, arc 

 all exclusively Palrearctic. 



Among Carnivora we have Nydercutes, the curious racoon-dog 

 of Japan and North-Eastern Asia ; Lutronedcs, an otter peculiar 

 to Japan ; and the badger {Mdes), which ranges over the whole 

 region, and just enters the Oriental region as far as Hongkong ; 

 JEl'uropus, a curious form of the Himalayan panda, inhabiting 

 the high mountains of Eastern Thibet ; and Pda<jius, a genus of 

 seals, ranging from the shores of Madeira to the Black Sea. 



The Ungulata, or hoofed animals, are still more productive of 

 forms peculiar to this region. First we have the Camels, whose 

 native home is the desert region of Central and Western Asia and 

 Northern Africa, and which, even in their domesticated condition, 

 are confined almost wholly within the limits of the Palfearctic 

 region. Of Deer we have six peculiar genera, Dama and Cajjrcolus 

 found in Europe, with Elaphodas, Lophotragiis, Hydi'opotes, and 

 Moselius, confined to Northern China and Mongolia. The great 

 family Bovidas — comprising the oxen, sheep, goats and antelopes 

 — furnislies no less than seven peculiar rala3arctic genera. 

 These are FoepJiagus, the yak of Thibet; Addax, a well-known 

 antelope of Northern Africa and Syria ; Procapra, Pantlw- 

 lops and Budoi'cas, antelopine genera peculiar to Thibet and 

 Mongolia ; with Bupicapra (the chamois), and the extraordinary 

 large-nosed antelope Saiga, confined to Europe and Western Asia. 

 Besides these we have Capra (the wild sheep and goats), all the 

 numerous species of which, except two, are exclusively Palsearctic, 

 Coming to the Eodents, we have again many peculiar forms. 

 Of Murida; (the mouse and rat tribe), we have six peculiar 

 genera, the more important being Cricetus, Rhomhomys Smin- 

 thus, and Myospadax. Of Spalacidye (mole-rats) both the Palse- 

 arctic genera, Ellobius and Spalax, are peculiar. Ctenodadylus, 

 a genus of the South American family Octodontidse, is found 

 only in North Africa. To these we may add Myoxus (the 

 dormice) and Lagoriiys (the pikas or tail-less hares) as essentially 

 Palsearctic, since but one species of each genus is found be- 

 yond the limits of the region.
