the back of the neck, bright buffy-yellow or orange-buff ; lores, 
forehead, a broad stripe over the eye continued round the nape 
and the back of the neck, pale blue-grey, dull and tinged fawny 
in some specimens; crown, occiput, and nape, a sort of dove-

with fawn; the upper tail-coverts buffy-yellow, all but the 
longest obscurely tipped with a somewhat pinkish-mouse color. 
They are more or less pale dove-color at their bases, which color 
however is not seen till the feathers are lifted. The central tail- 
feathers have the pointed tips black, in many specimens more or 
less tinged horny-buffy, and the rest of the visible portion 
yellowish-buff, but the bases, as may be seen on lifting the 
feathers, are greyish; the lateral tail-feathers are a greyish-brown 
at base, dark shafted, with conspicuous white tips, and broad 
blackish-brown subterminal bands; the primaries are pale 
isabelline, the shafts- conspicuous and black; they have broad 
ill-defined subterminal brown bands, beyond which there is a 
narrow paler tipping, and they are pretty conspicuously margined 
on their inner webs towards the tips with still paler isabelline; 
the first primary has the outer web browner, the others have the 
outer webs, especially towards the bases, a brighter isabelline. 
The whole visible portions of the lesser-coverts and of the 
primary greater-coverts are yellowish-fawn, or isabelline, varying 
much in shade in different specimens; these greater-coverts are 
dark shafted, and with a brownish tinge next the shafts on the 
inner webs; the scapulars bluish-grey at the bases, tipped broadly, 
but chiefly on the outer webs, with buffy-yellow, and the lesser 
ones tinged immediately above the yellow with a somewhat 
brownish-purple, or dull greyish-vinaceous; the secondary, 
median, and greater-coverts like the lesser scapulars. but showing 
more of the vinaceous hue. The secondaries are brown, lighter 
towards their bases, the lower part of the neck in front 
and breast are nearly the same blue-grey or greyish-fawn as 
the back of the neck; the lower breast, abdomen, sides, 
flanks, axillaries, and wing-lining isabelline or desert color, the 
upper abdomen often with a faint orange-buffy tinge; a broad 
deep irregular brown patch runs down the centre of the abdomen 
to the vent; the lower tail-coverts are greyish-brown at their 
bases, but are broadly tipped with white (often tinged buffy or 
isabelline) which is the only color visible until the feathers are 
lifted ; the lower surfaces of the quill shafts are white. 
The female has the yellow chin and throat patch like the male, 
but paler ; the lores and feathers immediately encircling the eye 
pale isabelle white; the whole upper parts and the neck all 
round pure isabelline, tinged slightly rufous on the occiput, 
nape, and back, and conspicuously spotted with dull, somewhat
