GOAT COUNTRY ON THE SUMMIT OF THE MAIN ROCKIES
EAST OF THE MAIN ROCKIES, INDICATING CHARACTER OF COUNTRY WHERE GOAT, SHOWN ON PAGE 14, WAS SHOT.
In western Europe we find first the chamois (Rupicapra), known in the Spanish Sierras and Pyrenees as the izard, and extending eastward through the Alps and Carpathians as far as the Caucasus. Throughout all this range only one species is recognized.
The next genus of this group is the goral (Cemas), with four species ranging throughout the Himalayas and parts of China, into Amurland.
In Tibet we have the third and decidedly most aberrant member of the Rupicaprinæ, the takin (Budorcas), the horns of which suggest those of the gnu. Only one species of this genus is known.
The fourth, and to Americans perhaps the most interesting Old World member of this Subfamily, is the serow (Næmorhedus), locally known as the forest goat. This genus is perhaps, more closely allied to Oreamnos than any of the preceding genera, and its horns resemble those of the mountain goat, but are shorter and thicker. The genus Næmorhedus inhabits the Himalayas, Tibet and China with outlying representatives in Burma, Sumatra, Formosa and Japan and it is divided into numerous species. The fifth genus is Oreamnos, the subject of this article.
All the members of these genera resemble the goat in tooth structure, but differ widely from them in the position and shape of the horns, face glands and other important details. The whole group is to be regarded as an early off-shoot of the Bovidæ, to some extent intermediate between the goats and the true bovine antelopes. The Rupicaprinæ must have pushed north, with their not distant ally the musk-ox, at a very early time and become adjusted to alpine and boreal conditions. At the close of the glacial period many of its members deserted the low country and retired to high altitudes so that in some instances, notably that of the chamois, we have an example of discontinuous distribution. Its sole American representative probably reached this continent by way of the Bering Sea land connection, during the middle Pleistocene, together with the other American genera of the Bovidæ.
