Tail cinnamon-brown, shaded grey marginally and vermiculated black, and crossed witli five 

 paler bars (not joining the shafts), subterminal series (sic). The bars are edged black and 

 obscnrely vermiculated. All underparts from bill -sinous rusty, with a group of white black- 

 margined patches on throat, and another across bottom of breast, below which the colour is 

 paler and broken with rusty and dusky irregular bars ; this extends to lower tail-coverts. Lower 

 back and upper tail-coverts as back. A pale tawny supercilium. Lining of wings whitish. 

 Length 9 inches, wing 4f, tail 4|^, of which beyond body 2^, biU f, tarsus -f-g, middle

This description refers to the rufous phase, when the upper plumage is traversed and 

 vermiculated by narrow brown lines, while otherwise the bird exhibits the adult markings. 



No. 3, 2 C?) young, ex Malacca (7nus. nostr.). Chin and upper throat tawny white ; rest of 

 throat tawny rufous, feathers tipped brighter rufous and with distinct indications of white ocelli. 

 Upper breast the same. Lower breast-feathers tawny white, with rufous margins (somewhat as 

 in B. sfellafiis, 2 adult). No traces of the pure white drops on the lower pectoral plumes. 

 Abdomen, ventral region, and under tail-coverts sordid white, with traces of pallid rufous. 

 Frontal band and supercilium tawny rufous. Crown and occipital crest-plumes as in adult. 

 P. Z.S.I 877, '\^'hite nuchal collar distinctly indicated, the white of the band not being pure. Back and 

 P' ■ uropygium dark rufous, traversed by narrow black irregular lines. Upper tail-coverts pale 

 rufous, striated with black or brown. A few scapulars showing indications of the white 

 markings of the adult. The rufous part of all the quills with distinct, transverse, irregular 

 black lines. Rectrices as in adult ; but the paler rufous intervals are round, and do not touch 

 the shafts. Sides of the neck creamy white. No lengthened auriculars. Wing 4-50, tail 4T2, 

 bill from forehead 0'81, width of gape 0*88. 



The example here described seems to be of a nestling female passing over to the inter- 

 mediate finely striated phase. It is full of blood-feathers. An example, ex Sumatra (Mas. 

 Brit.) is in similar plumage. 



No. 4, d (l) adiilt, Malacca {mns. 7wstr.). General aspect grey, greyish white, greyish 



rufous, rufous brown, with a white nuchal collar, white-marked scapulars, white throat and 



pectoral plumes. Frontal plumes tawny at their insertion, tipped and marked with brown, a 



bold buff supercilium, edged above with a series of buff feathers with brown tips and freckles. 



Crown-feathers greyish, with dark brown tips and small tawny-white marks on the margins of 



the webs of some. Lengthened auriculars tawny white the greater part of their length, freckled 



with brown, and tipped dark brown. Occipital crest like the crown-feathers, but tinged with 



rufous at their extremities, forming witli the upper nape-feathers an obscure rufous-tinged collar. 



A conspicuous nuchal collar formed by a series of feathers which, pale rufous tawny grey at 



their insertion, are, lower down, traversed by a narrow brown zigzag line, then by a narrow band 



of pure tawny rufous, which is separated by a second irregular brown transverse line from a 



broad pure white band, which, in its turn, is bounded by a black terminal border to the feather, 



in some freckled with tawny. Interscapulars grey, with a rufous tinge, minutely freckled with 



brown, some with black, terminal small spots. Back the same, but less rufous, and with fewer 



black terminal dots. Upper tail-coverts rufous, with tawny dots and brown freckles. Some 



scapidars pure white, with a black terminal spot and a narrow margin (in parts) of black ; near 



insertion a few zigzag pale brown markings. Several other scapulars with inner webs grey,
