_Pucrasia_ contains six species or local races of "Pukras" or Koklas Pheasants, with long, black, erectile ear-tufts in the male, which has a spur on each metatarsus, but no naked cheeks. _P. macrolopha_ of the Western Himalayas has a well-developed buff crest, a greenish-black head and neck with a white patch on each side of the latter, grey upper parts and whitish flanks with black shaft-stripes, brownish wings marked with buff, chestnut under parts and median feathers of the elongated, wedge-shaped tail, and blackish lateral rectrices with white tips. The black and rufous hen has a white throat, a short crest, and no ear-tufts or spurs. _P. castanea_ of North Afghanistan and Kafiristan has the mantle chestnut, _P. nipalensis_ of the Central Himalayas black varied by grey and reddish; _P. meyeri_ of South Tibet and the {213}Upper Mekong possesses a yellow nuchal collar; _P. darwini_ of East China has grey bases to the outer tail-feathers; _P. xanthospila_ exhibiting both. These monogamous birds attain a somewhat higher elevation than the Cheer, and utter a loud, deep crow; but otherwise the habits are the same. The five to nine pointed eggs are buff, speckled or blotched with red-brown. _Gennaeus_[157] has a long vaulted tail, a fine crest, naked sides to the face covered with red skin or wattles, and metatarsi with a single spur in the male. In _G. albicristatus_ of the Western Himalayas the crest is white, the head and upper parts being black with purple and blue reflexions and white margins to the dorsal feathers, the primaries and abdomen brown, and the breast whitish. The female is reddish-brown, with delicate black markings on the grey-margined upper feathers, and shews white below and on the wing-coverts. _G. leucomelanus_, with blue-black crest, inhabits Nepal; _G. muthura_ (_melanotus_), without white on the lower back, occurs in Sikkim and Bhutan; _G. horsfieldi_, with black breast, extending from East Bhutan to North Arakan and Upper Burma. All the above species have the tail black, or rarely vermiculated with white; but in _G. lineatus_ of Burma, Siam, and Tenasserim, and the very similar _G. andersoni_ of Upper Burma and West Yunnan, it is banded alternately with black and white, and the median rectrices are even whiter. _G. edwardsi_ inhabits Annam. _G. nycthemerus_, the Silver Pheasant of South China, embroidered as a badge on mandarins' dresses, and introduced into England early in last century, has an extremely long white tail, obliquely marked with black on the lateral feathers, a purplish-black crown, crest and lower surface, white back of the neck and upper parts with crescentic black lines on the latter, and naked red face. _G. swinhoii_ of Formosa is easily distinguished from its allies by the bronzy-crimson scapulars, white crest, upper back, and median rectrices; the remaining plumage being bluish- or purplish-black with a glossy dark green band upon the wing. The female is mottled with rufous,
