and front of the neck, slight greyish or brownish white, very narrowly, 

 regalarly and closely streaked with brown ; the lower parts a slightly 

 brownish white ; the breast feathers with greyish brown subterminal 

 transverse bars, mostly more or less concealed by the pale tippings of 

 the superincumbent feathers, and only clearly seen when the feathers 

 are lifted ; the sides and flanks similar, but the subterminal bars much 

 broader, and some of the flank feathers with several bars ; the vent 

 feathers and lower tail- coverts, generally, with a slightly more rufescent 

 tinges and with two or "more narrow, widely, separated, transverse 

 brown bars; the tibial plumes browner, and with numerous narrow 

 closely- set, but ill-marked, transverse brown bars ; the abdomen more 

 or less obsoletely mottled with very pale grey brown, which, on lifting 

 the feathers, is found to arise from more or less faint, irregular, trans- 

 verse, subterminal, brownish bars. 



'' The barrings above described are very much more marked in some 

 specimens than in others, in some in fact they are almost entirely 

 obsolete on the abdomen, and can hardly be traced. 



" The upper back greyish brown, the feathers with a subterminal richer 

 brown bar ; scapulars brown, each feather with a yellowish white termi- 

 nal spot, and of a much richer brown, the longer ones especially, just 

 above the spot; the tertiaries and secondary greater-coverts are greyish 

 brown, the former obsoletely barred paler; the secondaries are pale 

 grey ; the primaries, their greater-coverts, and the winglet pale slaty, 

 the primaries with a silver grey tinge on the outer webs towards the 

 tips ; the inner webs pale grey brown, except towards the tips, where 

 they are much darker, and where the shafts also are conspicuously 

 darker; the middle back, rump, and upper tail-coverts the same 

 grey brown as the upper part of the back ; the feathers of the middle 

 back narrowly and obscurely tipped with yellowish white, those of 

 the rump and upper tail-coverts more broadly and conspicuously so, 

 and with a subterminal dark brown spot; the longest of the upper 

 tail-coverts are very broadly and conspicuously so tipped, and have 

 a subterminal dark band; the tail feathers pale grey brown, broadly 

 tipped, and narrowly margined with yellowish white ; the two central 

 tail feathers darker on the inner webs and dark shafted, and the lateral 

 tail feathers paling as they recede from the centre. 



" The female is similar, but smaller, with the eye patch and generally 

 all the marking and tints duller and less conspicuous. 



" The legs and feet are dusky olive or dark horny brown ; bill bluish 

 grey, black on culraen and tip, or dusky, bounded at the margins of 

 the feathers of the forehead and cheeks with a pale, leaden blue line 

 continued along the margin of both mandibles to near the tip, and a 

 spot of the same colour just above the nail ; the irides are brown. 



" The dimensions of this species are as follows : — 



" Male— Length 18-3 to 19, expanse 28-5 to 29-5, tail from vent 3-6 to 

 4,wing 8'1 to 8"5, wings when closed reach to within 0'7 to 1*5 of end 

 of tail, bill at front, including nail, I'll to I'SS, tarsus V44 to \b2,
