DISTRIBUTION OF MAMMALS. 



I. Palcearctic Eegion. Thirty-five families represented. Peculiar 

 Genera. The camel, six deer, the yak, six antelopes (including the 

 chamois), and all wild sheep and goats, except two species. Six 

 p.g. of Muridce (rats and mice), two of mole-rats, and one other ; 

 dormice and pikas (calling hares) are almost confined to this 

 region. Six p.g. of moles ; the remaining two genera of which 

 (Talpa, Urotriclms) extend, respectively, into N. India and N. W. 

 America. Five p.g. of Carnivora, including the racoon-dog, a 

 seal, and the badger ; the last just enters the Oriental region in 

 China. 



II. Ethiopian Region. Fifty families represented, of which nine 

 are peculiar i.e., Onjcteropodidce. Hippopotamidce ; Camelopardidce. 

 Potamogalidcv (including Potamogale, an otter-like Insectivore) ; 

 Chrysocldoridce (golden moles). Cryptoprodidce (Cryptoprocta is a 

 small civet -cat -like form peculiar to Madagascar) ; Protelidce 

 (Proteles, the aard-wolf, is allied to the hyaenas and weasels) ; 

 Cheiromyidce (contains Cheiromys, the aye-aye, peculiar to Mada- 

 gascar). 



Peculiar Genera (besides those in the above families). Potamo- 

 chaerus (river hog), and Phacochaerus (wart hog) ; Hyomoschus 

 (a small deer-like form), twelve p.g. of antelopes. Thirteen p.g. 

 of Muridce; Pedetes (a jerboa or jumping mouse); Anomalums 

 (a flying squirrel) ; three other p.g. of Kodents. Three p.g. of 

 elephant-shrews, and the Insectivorous family Centetidce, except 

 one genus from Cuba and Hayti. Three p.g. of bats. Seventeen 

 p.g. of Viverridce (civets and ichneumons), two p.g. of dogs, and 

 two p.g. of Mustelidce (weasels, otters, &c.) Nine p.g. of Lemurs. 

 Eight p.g. of apes and monkeys, the most important being Trog- 

 lodytes (gorilla and chimpanzee). 



Peculiar Species. Among these are several species of Manis, 

 the two-horned African rhinoceroses, the zebras, African elephant, 

 and lion. 



Absent Palcearctic Forms. The genera Bos (wild ox), and Sus 

 (wild boar), camels, deer, goats and sheep, moles, bears. 



III. Oriental Eegion. Forty-two families represented, of which 

 two are peculiar, and one other almost so i.e., Galeopithecidce 

 (including Graleopithecus, the flying lemur), and Tupaiidw (tree- 

 shrews), among Insectivora. Tarsiidce, a family of lemurs (includ-
