Description. — Male. Crown of head with the feathers thick-set and 
somewhat long_, but not forming a conspicuous crest; whole head and 
neck greyish brown stippled with brown ; lower plumage pale ochraceous 
barred with brown; whole upper plumage, wings and tail dark brown, 
minutely speckled all over with greyish white ; the feathers of the back, 
scapulars, tertiaries and wing-coverts tipped with pale buff, and each having 
near the tip a large roundish violet-blue spot, tinged with a coppery gloss 
next the buff tip ; each tail-feather with a large oval metallic-green patch 
on each web, surrounded by a blackish and then by a buff ring. 
The female is similar in general appearance to the male ; but the spots 
on the back and upper plumage are dull, and those on the tail are very 
small and inconspicuous; the spots on the tail-coverts are altogether 
absent. 
In the male the legs and feet were blackish, the claws black; upper 
mandible and tip of lower mandible black, rest of lower mandible and 
facial skin pale yellow ; irides white. The female had the legs and feet 
very dark plumbeous ; upper mandible dark horny brown, paler on cere ; 
lower mandible pale brown ; irides deep grey ; facial skin pale dingy fleshy 
yellow. {Davison.) 
An allied species is P. bicalcaratum, which is said to have occurred 
at Mergui. Mr. Blyth, however, does not include it in his list of Burmese 
birds ; and Mr. Davison does not appear to have met with it in Tenasserim. 
I shall therefore not include it in my work, but merely indicate it here. 
It is about the same size and form as P. chinquis ; but it may be recognized 
by the male having a well-defined sharp-pointed crest of narrow bluish 
feathers, the upper plumage of a clear bufi" spotted with black, and the 
ocelli green, not violet-blue. The female is similar to the male in general 
colour ; but the ocelli on the upper plumage are blackish, without gloss, 
and those on the tail are very small. 
The Grey Peacock-Pheasant is found abundantly in Arrakan. I have 
never procured it in any part of Pegu, nor heard of any one having done so 
— which is rather strange, for the Pegu hills seem well fitted for it. In
