Coloration. Male. Forehead, crown, and crest black with purplish or green gloss ; feathers of the upper surface marked on each web with subequal curved concentric black and white bars ; quills and tail-feathers rather irregularly barred with black and white, the black bars disappearing on the inner webs and tips of the middle tail-feathers; lower parts black with bluish metallic gloss.

Female of typical form unknown. That of a variety from Tenasserim only differs from G. lineatus in being larger and in having much broader lanceolate white stripes on the lower surface.

Bill pale green (Elliot), pale bluish horny (Davison); facial skin crimson ; irides brown; legs and feet greyish (Elliot), dark pinkish fleshy (Davison).

Length of male 30 to 36 ; tail 13.5-20 ; wing 10.5 ; tarsus 3.5 ; bill from gape 1.6. Length of female 24 ; tail 10 ; wing 9; tarsus 3.

Distribution. This Pheasant was originally obtained by Anderson in Yunnan. It has since been found near Bhamo, around the Ruby Mines, and through the Shan States to Northern Tenasserim, Davison having procured a male and three females that are referred to this species about Kollidoo and Dargwin, north of Papwon.

But few specimens have been collected, and these show material differences. The male obtained by Davison at Dargwin has white stripes on the breast, and has the inner webs and tips of the middle tail-feathers nearly white, as in G. lineatus, and is clearly intermediate between that species and typical G. andersoni: the tail is about 14 inches long. Yet another link nearer to G. lineatus is furnished by a male collected by Wardlaw Ramsay in Karennee. The skin of another male, from the typical locality Yunnan, mentioned by Anderson as one of his original specimens, and sent by him to the British Museum, is intermediate between G. andersoni and G. horsfieldi, and is the type of Ogilvie Grant's subspecies G. davisoni. A skin from the Ruby Mine's has coarser markings on the wings and a tail of nearly 20 inches. I strongly suspect G. andersoni to be merely an intermediate race between G. lineatus and the Chinese Silver Pheasant (G. nycthemerus).

Mr. Oates has sent to the British Museum a Pheasant from the Shan States, that forms yet another link between the Chinese and Burmese Silver Pheasants. In male 67. nycthemerus from China the upper surface is white, with narrow wavy concentric black lines on the feathers ; the crown, crest, and lower parts black with a purple gloss. The female is light rufous brown ; the crown and crest darker, the lower parts paler, most of the feathers finely vermiculated with buff, more coarsely barred on the wing and tail-feathers. Bill greenish brown ; facial skin red; legs and feet scarlet. The male is about 40 inches long ; tail 24; wing 10.5 ; tarsus 3.6 : female 20 inches long; tail 10 ; wing 9.
