| March, and several of more or less incubated ones found during 
the first ten days of May, but the great majority of the nests 
The next 4 on either side similar, but the grey occupying more and more of 
the inner webs, which have 5, somewhat incomplete, transverse bars, of dark 
brown. The 2 exterior have the tipping and subterminal band, faint. A 
narrow streak of rufous, along the shaft, on either side. A considerable 
portion of both webs atthe base white, and the rest a greyish brown, with 
here and there a trace of darker mottling. The whole of the lesser and 
median wing coverts, a paler brown than the rest of the body, all with dark 
brown shafts, narrowly margined with fulvous or pure white, most conspicu- 
ously on the longer feathers ; the inner webs of many of the median coverts, a 
good deal mottled with white. Winglet, and primary greater coverts, dark 
brown, the feathers excessively narrowly margined towards the tips with 
white, most of them paler, and even white on the inner web towards the base, 
and the first feather of the winglet, and the first 2 coverts, with a manifest tinge 
of grey on the outer web. The greater coverts of the secondaries, a sort of 
sandy or fulvous brown, the shafts darker, and both webs indistinctly tinged 
with grey, towards the shaft, above the tips, The primaries dark brown at the tips 
with very narrow whitish margins. The outer webs darkish brown, (lighter 
towards the secondaries) more or less tinged, or frosted over, in the first 5, 
with silver grey, purest on the Ist. The first 4 feathers are conspicuously 
emarginate on the inner web; below these emarginations, and above the dark 
tipping, the inner web is a sort of greyish brown, with a few faint darkish 
brown blotches, or incomplete bars ; above the emarginations, they are pure 
white. ‘The rest of the primaries, which have an obscure rufous tinge along 
the shafts, have about halfthe inner webs greyish brown, with 4 or 5 transverse 
darker brown bars, and the other half white, the line of junction being oblique, 
there being less white towards tips, and less brown towards base. The inner webs 
of the secondaries are similar, but their outer webs are chiefly greyish brown, the 
white margins of the tips are broader than in any but the first few primaries, and 
the broad dark brown tip of the primaries is replaced by an inconspicuous patch 
of a lighter brown on the tip of the inner web only. The chin and throat are 
pure white,the feathers very lax,bordered by a broad stripe of darkish brown from 
the base of the lower mandible on each side, and with a similar stripe down the 
centre of the chin and throat. The rest of the neck in front, in some specimens, 
arather pale fulvous brown, tipped inconspicuously with white, dark shafted, 
and somewhat mottled with a fulvous white. ‘The breast and the greater part 
of the sides and upper abdomen, white, the feathers irregularly but broadly 
barred, with a pale rufous or fulvous brown. In other specimens the whole 
of the rest of the neck, breast, abdomen, and sides are a nearly uniform, pale 
but somewhat rufous umber brown, the feathers dark shafted, and with 
traces of imperfect fulvous white bars, nowhere extending to the shafts. 
Thigh coverts pale rufous, whitish towards the tip; most of the feathers, in 
some specimens, with a triangular patch of rufous brown towards the tips. 
Lower abdomen, white, or fulvous white, the feathers, with only a more or less 
faint, triangular patch of pale rufous, or rufous brown towards the tip. Vent 
feathers and lower tail coverts white, tinged, more or less distinctly, with very 
pale yellowish brown. Under surface of tail feathers, greyish white, the 
subterminal dark band showing through in all but the exterior feather. 
Under surface of the quills white, the broad dark tips of the primaries, and 
the dark patches at the tips of the secondaries, and the dark transverse bars 
on the inner halves, of the inner webs, of all the quills, (except in some 
specimens in the first five primaries,) showing through. The wing lining beyond
