Burmali ; and Dr. Jerdon, indeed^ states that it does occur in Burmah and 
Malayana. I am not, however, satisfied that Dr. Jerdon wrote from his 
own knowledge, and therefore I do not include it in the present work. 
This species is larger than H. nisicolor, and the under surface from the 
breast downwards is barred, not streaked. The wihg measures about 8 
inches in length.

Descriptio7i. — Male. The whole head and neck all round and the upper 
breast clear ashyj back, scapulars, coverts and wings brown, overspread 
with a green gloss ; a white patch on the inner webs of the quills ; rump 
and upper tail-coverts dark ashy_, most of the feathers tipped paler ; tail 
dark brown, tipped w^ith white ; the central feathers notched with white on 
both webs, the others barred with white on the inner webs ; lower breast, 
abdomen, vent, under tail-coverts, sides of the body and under wing- 
coverts rufous ; some males have the rufous extending up to the throat. 
Females, as far as my experience goes, do not assume the plumage of the 
male. The whole upper plumage, wing-coverts and tail are ferruginous^ 
closely barred with black ; the whole lower plumage is rufescent white, 
closely and finely barred with brown ; the wings are brown, with some 
broken rufous bars on the outer webs. 
Young birds are like the females, but the head, neck, throat and breast 
are streaked, not barred, with brown. 
Iris pale yellow ; upper mandible dark horn ; lower mandible brownish 
orange, except the tip, which is brown; feet brownish yellow or deep 
yellow ; the irides are sometimes brown and occasionally crimson. 
Length 9 inches, tail 4*9, wing 4*4^ tarsus '7, bill from gape •9. The 
female is of the same size or rather larger. 
Birds from Pegu have the wing varying from 4 to 4*6 inches in length ;
