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 sui'face of the tail is buffy white, crossed by eleven 

 irregular narrow dark bars ; the l)reast, 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 tibiae 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.
