(1925) Gennaeus lineatus sharpei.
GRANT'S SILVER PHEASANT.
Gentians sharpei Oates, Man. Game-B., p. 357 (1898) (Salween).
Vernacular names. Tit (Burma).
Description.— Adult male. Differs from the preceding bird in having the upper plumage marked with definite black-and-white bars rather than vermiculations, whilst these bars follow to some extent the contour of the feathers instead of being across the feathers ; from all the races placed under the name of nycthemerus it differs in having much more black and much less white.
Colours of soft parts. Iris brown; facial skin deep crimson; bill pale bluish-horny; legs and feet pinkish flesh-colour to reddish-horny.
Measurements. Wing 249 to 251 mm.; tail 348 to 353 mm.; tarsus about 86 mm.; culmen about 35 mm. Weight 2.75 lb.
Female. Similar to the female of G. l. lineatus but darker, less rufous below, with still broader streaks of white on the lower plumage.
Measurements. Wing 213 to 243 mm.
Distribution. South Shan States, East Central Burma and Siam. With the material available it is impossible to define the limits of the various species and subspecies of Gennaeus with any accuracy. All seem to wander greatly and all depend much on elevation and type of forest or jungle for their habitat and where high ranges of mountains run far into country of otherwise low hill, or where deep wide valleys intersect high mountainous country, the habitats of the several groups appear, on the map at least, to overlap in the most intricate way.
An immense amount of work still remains to be done by our field-collectors and much more material must be collected before we can properly understand this remarkable group of Pheasants. Moreover, every individual skin collected must have as much data given with it as is possible, and, finally, every bird collected during the breeding-season is, however brutal it may appear to-be to say so, worth ten collected in the non-breeding season.
Nidification. Nothing on record but in the Herbert collection there are three eggs taken by Gairdner at Ratburi, Western Siam, on the 3rd of April. The three eggs measure 45.8 x 35.8, 45.0 X 35.3 and 45.2 X 35.1 mm. In colour they are a warm buff.
Habits. Nothing recorded but probably differing in no way from G. l.. lineatus except in frequenting higher hills between 2,500 and 5,000 feet, especially those which have a certain amount, of grass-lands on their higher slopes.
