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 Himalayas
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.).
