tips. Nape with a distinct rufous tinge ; a few feathers on each 

 side broadly terminated with white, which is margined above by a 

 narrow brown hne ; a few feathers on the middle of the nape slightly 

 tipped with pure white, some with fulvous. A rudimentary uncom- 

 pleted nuchal collar is thus formed. Back and uropygium rufous- 

 brown like the nape, marked with cloudy brown striations and a few 

 black terminal dots. Upper tail-coverts rufous brown, with pale 

 lateral subdued small spots or quasi-bands. Scapulars greyish white, 

 much marked with irregular pale-brown strise, tipped pale rufous, 

 with a small terminal black spot almost encircling a minute rufous 

 point. The lower scapulars are thus marked on the outer webs only, 

 the inner being rufous, clouded with brown. Wing-coverts rufous 

 brown. The major and secondary coverts purer rufous and tipped 

 with bold round or ovoid white marks, some tawny, surrounded above 

 and on their inner margins with black. Many of the greater coverts 

 are traversed by brown zigzag lines ; and the white tips are irregu- 

 larly formed and incomplete. The quills are brown, the outer webs 

 being indented with pale rufo-fulvous. The tertiaries brown, mottled 

 with grey and rufous-grey, which resolves itself into more or less 

 definite bands on the sides of the webs. Middle rectrices rufous- 

 brown, with eight or nine pale fulvous-grey narrow transverse bands 

 much dotted with brown ; laterals brighter rufous. Under wing- 

 coverts pale sordid fulvous grey. Wing 4-68, tail 4-50, tarsus 0'50, 

 middle toe 0"7.5, bill from forehead 0-yO, width of gape 1-20, 

 Structure as in foregoing. 



No. 4, d (?) adult, Ceylon (mus. nostr.). (PL XLVliI.) ireneral 

 aspect above brown. Group of feathers before the eye pale rusty, 

 with a dark brown subterminal bar ; a narrow frontal band similarly 

 marked. Superciliary plumes pale rusty white, mostly on the outer 

 webs, freckled with brown on the inner and traversed with a sub- 

 terminal dark brown irregular line. Feathers of the head brown, with 

 minute fulvous terminal and marginal dots and subterminal black 

 spots, all obsoletely freckled with fulvous, and many mixed with grey. 

 Occipital crest-plumes without any fulvous dots. Elongated auricu- 

 lars tawny, much striated with brown, and tipped almost black. 

 Shorter auriculars tawny, with pale shafts. Nuchal plumes marked 

 like occipital crest, but with a more tawny-rufous ground and with a 

 subterminal white band confined between an upper and a terminal dark 

 brown transverse line. A well-defined nuchal collar is thus formed of 

 two or three rows of plumes. Interscapulars and back marked and 

 coloured like the occipital crest. Uropygial plumes rusty, irregularly 

 vermiculated with dark brown, some terminal markings being black. 

 Upper tail-coverts the same, but with obsolete pale rusty lateral 

 ocelli. Rectrices pale rusty fulvous, mixed with grey throughout, 

 much vermiculated by fine irregular brown lines and with some seven 

 or eight darker rufous transverse bands, separated from the paler by 

 dark brown, almost black, irregular lines, these being broader and 

 bolder than the fine vermiculations. liaterals with a brighter tawny 

 rufous ground-colour. External short pair pale tawny-rufous, with 

 pure white marginal spots. Undersurface of the rectrices pale ful-
