The average wing measurement of twenty-six females is 8*7" 

 (221-0 mm.). 



" Weight 2 lbs. to 2-5 lbs." (Hume.) 



The crest is considerably shorter than in the male, varying from 

 2-2" (55-9 mm.) to 2-75" (69-8 mm.), but is generally about 2-5" 

 (63-5 mm.). 



Young Male. — Similar to the adult female. 



Chick in Down. — Head above rufous, forehead and above eyes paler ; 

 a streak behind the eye extending over the ear coverts rich chestnut, 

 much darker than the crown ; above dull rufous brown, darkest 

 along the back and paling on tlie sides ; below dirty bufFy white with 

 very faint indications of a chestnut collar at the sides of the 

 breast. 



The variations in plumage in the male birds are not great, though 

 in the extreme East and North of its rana^e the markino-g become 

 somewhat bolder on the upper surface and the extent of white on 

 the sides of the breast and Hanks somewhat more plentiful. 



The females vary considerably ; in many the white markings on 

 the breast are streaks, and not V-shaped marks, the black edges to 

 these marks are obsolete or absent, and the general colour is duller 

 and darker. In some females also the white marks on the upper 

 plumage commence on the nape, whilst in others the forehead and 

 supercilia are freely marked with white. The proportion of black 

 and chestnut on the outer tail feathers also varies extremely, as does 

 the depth of the buff on the central ones. 



Bistrihution. — The fact that on all the boundaries of its habitat 

 this form grades through its various subspecies into nycilietnerus 

 and horsfiddi makes it extremeh' difficult to define its range with 

 any exactitude. On the West the Irrawaddy undoubtedly divides 

 it from oatesi, biit at the same time one meets with numerous spe- 

 cimens in the extreme South and East of the Arrakan Yomas 

 which approach tj'pical linfatn-'^ very closply, and this magnificent 

 river does not form as sharplv cut a defining boundary as similar 

 great rivers do with many other species of birds. To the North it 

 extends up to Thaungja, i.e., 20° about, but West of the Sittang, 

 where the Northern parts are more mountainous it appears only to 

 be found as far North as Thauugoo, Thardoiing and Kolidoo. In 

 the higher hills of the Bree Countrj'- and again East of the Sal win in 

 the Soutlieni Shan States it is replaced by sharpei. West it 

 crosses the Sal win South of Dargwin, and has been reported from 

 Rahang on the JNIewang River, but here, on the higher hills at all 

 events, a bird more closely allied to sharpei is the common form. 

 South of Muleyit it again appears to wander East across the Klang 

 River, and stretches as far South as 14° and quite possibly much 

 farther South than this, as Gyldenstolpe records a Silver Pheasant 

 as far South as 12°.
