486 Mr. J. H. Gurney’s Notes on 
the lateral rectrices this interval is occupied by another inter¬ 
mediate transverse bar; the intervals between the several 
bars are greyish brown on the central rectrices, but tinged 
with rufous on the external webs of the remainder, the cor¬ 
responding intervals on the inner webs being pale buff; the 
under surface of the tail is huffy white, crossed by eleven 
irregular narrow dark bars; the breast, abdomen, and under 
tail-coverts are pale buffy white, the latter with narrow dark 
transverse bars at intervals of about half an inch; the wing- 
linings and flanks are pale buffy white, with a few dark brown 
feathers intermixed, especially on the flanks; the tibise are 
of a similar colour, but tinged with fulvous and mottled with 
irregular transverse dark markings, especially on the inner 
face of the thighs. 
Busarellus nigricollis, immature. 
The crown and back of the head, the nape, and sides of the 
neck are striated, each feather being dark brown, with a more 
or less broad buff or fulvous margin; the sides of the head 
are pale buff, tinged with grey on the ear-coverts; the upper¬ 
most scapulars and upper interscapulars are dark brown, with 
a rufous edging to each feather; all the remainder of the 
upper surface exhibits alternate transverse bars of rufous and 
dark brown on each feather, except the tips of the tail, the 
outer webs and all the lower portions of the primaries, the 
tips of the secondaries and tertials, and the feathers of the 
bastard wing, which are all dull black; the chin and upper 
throat are yellowish, the lower throat dull black; the breast 
fulvous, intermixed with longitudinal markings of rufous and 
dark brown; the abdomen and flanks are rufous, slightly 
mottled with irregular transverse markings of dark brown; 
the wing-linings and tibiae are similarly coloured, but with 
the transverse markings more regular; the dark transverse 
bars on the tail are six above and seven below, besides the 
broader terminal band, the interspaces being rufous on the 
upper and pale buff on the under surface. 
It may here be proper to notice a new genus and species,
