GEOGRAPHICAL ZOOLOGY. 
[PART IV. 
Columbia River, west to tlie coast range of California, and east 
to the Missouri. Its remarkable deciduous horns seem to indi- 
cate a transition to the Cervidae. (Plate XIX., vol. ii., p. 129.) 
Sub-family VII. Cervicaprin^e (5 genera, 21 species). This 
group of Antelopes is wholly confined to the continental portion 
of the Ethiopian region. The genera are: Cervicapra (4 sp.), 
Africa, south of the equator and Abyssinia ; Kobus (6 sp.), grassy 
plains and marshes of Tropical Africa; Pelea (1 sp.), South 
Africa; Nanotragus (9 species), Africa, south of the Sahara; 
Neotragus (1 sp.) Abyssinia and East Africa. 
Sub-family VIII. Cephalophike (2 genera, 24 species), Africa 
and India ; Cephalophus (22 sp.), continental Ethiopian region ; 
Tetraceros (2 sp.) hilly part of all India, but rare north of the 
Ganges. 
Sub-family IX. Alcephaline (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; Catoblepas (2 sp.), gnus, Africa, south of 
the Equator. 
Sub-region X. Budorcine (1 genus, 2 species) Budorcas in- 
habits the high Himalayas from Nepal to East Thibet. 
Sub-family XI. Rupicaprine (1 genus, 2 species) the Cha- 
mois, Bupieapra , inhabit the high European Alps from the 
Pyrenees to the Caucasus. (Plate I., vol. i., p. 195.) 
Sub-family XII. Nemorhedine (2 genera, 10 species). These 
goat-like Antelopes inhabit portions of the Palaearctic and 
Oriental regions, as well as the Rocky Mountains in the Xearctic 
region. Nemorhedus (9 sp.) ranges from the Eastern Hima- 
layas to N. China and Japan, and south to Eormosa, the Malay 
Peninsula and Sumatra. Aplocerus (1 sp.), the mountain goat 
of the trappers, inhabits the northern parts of California and the 
Rocky Mountains. 
Sub-family XIII. Caprine (2 genera, 23 species). The Goats 
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 Ovibos (1 sp.).
