. Natural history. Zoology. A VES—ORDER GALLIFORMES. the snow-line in summer, and is somewhat local in its distribution, inhabiting rooky situations, where its plumage blends with its surroundings, and makes the bird difficult to identify. It nests in the Himalayas at an elevation of from 12, 000 to 15, 000 feet, and is very tame, probably on account of its habitat being only reached by a most adventurous sportsman, whose visits are few and far between. These large and handsome birds are readily distinguished by their large size and by the number of their tail-feathers, which are 20 or 22 in number. The snow-cocks, or snow-pheasants as they are r' V called (Tetraogallus), are the largest of the partridge-group, Snow- ocKs. ^^^ g^j, g pj^jy found in high ranges, from tlie mountains of Tetraoaallus Asia Minor, the Caucasus, and Persia, to the Himalayas, Turkestan, the Altai, and the higher hills of Moupin and Korth-Western China. In the Himalayas, the snow-pheasant {T. liimalayensis) is an inhabitant of the snowy ranges, from which it only migrates to some- what lower altitudes on the approach of the winter snow. These birds are generally found in packs of from five to ten, but sometimes twenty or thirty are in a single flock ; and even during the nesting-season a good many are found in company. Snow-pheasants are birds of tlie open, rocky hill-country, frequenting grass-lands, and never entering the forest or perching on trees. They are, therefore, evidently gigantic partridges in their ways, and it is a mistake to call them snow-"pheasants, " as is so often done. The red-legged partridges differ from the true jjartridges in having only 14 feathers in the tail. They are also easily recognisable by the beautiful barring of red, grey, and black of the sides of tlie body. The most familiar of all the group is the red- legged partridge of England {Caccahis i~iifa}, which is confined to South-Western and Western Europe. In JSTorth-West Africa, Sardinia, and Southe
