ochraceous. The exposed portions of primaries and tail are 
yellowish brewn. 
Colours of soft parts. Iris pearly-white to grey ; eyelids slaty ; 
upper mandible brownish-horny, darker at base and on culmen, 
lower paler and yellowish; legs and feet pale dull fleshy, or 
fleshy-white. 
Measurements. Wing 66 to 72 mm.; culmen 12 to 13 mm. 
Distribution, Assam and Western Burma from the Chin Hills 
to the South of Arrakan. 
Birds from Assam and others from W. Burma differ in some 
respects, more especially in the tint of the grey on the head and 
again in the amount of rufous on the lower plumage. However, 
though material from Assam is plentiful, from Burma it is very 
scanty and more must be obtained before the value of the 
differences can be estimated. 
Nidification. The nest of this bird is merely a rather larger 
edition of that of the Nepal Babbler and is placed in quite similar 
positions. It breeds in great numbers in all the hills South of the 
Brahmaputra, not only at elevations up to 2,000 feet but also 
freely in the plains themselves. I have myself taken eggs as 
early as March and as late as September but May and early June 
is the principal breeding time. he eggs only differ from those of 
the Nepal Babbler in being larger, but the great majority are in 
colour of the clouded and smudged type described as No. 4 in 
that bird. One hundred and fifty eggs average 19°6 x 15°0 mm. 
Habits. The larger Quaker-Babblers of this group (potorcey hala) 
are rather more Vimaliine in their habits than those of the 
previous (nepalensis) group. More shy and retiring, they are also 
less quick and active in their movements. They use their legs 
more, yet are not so Tit-like in their actions and though they 
take readily to flight, they do not make the constant little sallies 
into the air, both in play and for food, like the Nepal Babblers 
do. I do not think they ever actually descend on to the ground 
to feed except for a second or two.

coronal stripes but in most these are quite absent. 
Colours of soft parts. Iris slaty-grey to slaty-yellow ; bill, upper 
mandible horny-brown, lower yellowish.
