224 GEOGRAPHICAL ZOOLOGY. [part iv. 



Columbia Eiver, west to the coast range of California, and east 

 to the Missouri. Its remarkable deciduous horns seem to indi- 

 cate a transition to the Cervidse. (Plate XIX., vol. ii., p. 129.) 



Sub-family VII. Cervicaprin^ (5 genera, 21 species). This 

 group of Antelopes is wholly confined to the continental portion 

 of the Ethiopian region. The genera are: Ccrvicapra (4 sp.), 

 Africa, south of the equator and Abyssinia; Kohus (6 sp.), grassy 

 plains and marshes of Tropical Africa ; Pelea (1 sp.). South 

 Africa; Nanotragus (9 species), Africa, south of the Sahara; 

 Neotragii^s (1 sp.) Abyssinia and East Africa. 



Sub-family VIII. Cephalophin^ (2 genera, 24 species), Africa 

 and India; Cephaloplms (22 sp.), continental Ethiopian region; 

 Tetraceros (2 sp.) hiUy part of all India, but rare north of the 

 Ganges. 



Sub-family IX. Alcephalin^ (2 genera, 11 species), large 

 African Antelopes, one species just entering the Palaearctic 

 region. The genera are : Alcephalus (9 sp.) all Africa and 

 north-east to Syria ; Catdblepas (2 sp.), gnus, Africa, south of 

 the Equator. 



Sub-region X. BuDORCiN^ (1 genus, 2 species) Budorcas in- 

 habits the high Himalayas from Nepal to East Thibet. 



Sub-family XI. PiUPICaprin^ (1 genus, 2 species) the Cha- 

 mois, Rupicapra, inhabit the high European Alps from the 

 Pyrenees to the Caucasus. (Plate I., vol. i., p. 195.) 



Sub-family XII. Nemorhedin^ (2 genera, 10 species). These 

 goat-like Antelopes inhabit portions of the Paleearctic and 

 Oriental regions, as well as the Rocky Mountains in the Nearctic 

 region. Nemorhedus (9 sp.) ranges from the Eastern Hima- 

 layas to N. China and Japan, and south to Formosa, the Malay 

 Peninsula and Sumatra. Aplocerus (1 sp.), the mountain goat 

 of the trappers, inhabits the northern parts of California and the 

 Rocky Mouniains. 



Sub-family XIII. Caprine (2 genera, 23 species). The G-oats 

 and Sheep form an extensive series, highly characteristic of the 

 Palaearctic region, but with an outlying species on the Neilgher- 

 ries in Southern India, and one in the Rocky Mountains and 

 California. The genera are Capra (22 sp.) and Ovihos (1 sp.).
