CHAULELASMUS. 187 



eyes, moderately dark brown, shading into the very dark brown immediately 

 surrounding the eyes ; the whole space between the sides of the upper man- 

 dible and the dark feathers surrounding the eye, the whole sides of the head 

 below the dark eye and ear patch, the whole chin, throat and front of the 

 neck, slight greyish or brownish white, very narrowly, regularly 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 tinge, 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 obso- 

 letely mottled with very pale grey brown, which on lifting the feathers is found 

 to arise from more or less faint, irregular, transverse, subterminal, brownish 

 bars. 



" The barrings above described are very much more marked in some spe- 

 cimens 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 terminal 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 obso- 

 letely barred paler ; the secondaries are pale grey ; the primaries, their greater 

 coverts, and the winglet pale slaty, the primaries with a silvery 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 conspi- 

 cuously 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 con- 

 spicuously 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 

 markings and tints duller and less conspicuous. 



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

 black on culmen 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
