430 THE MARQTJIS OF TWEEDDALE ON BATRACHOSTOMUS. [May 15, 



the white of the band not being pure. Back and 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 ])art of 

 all the 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 4- 1 2, bill from forehead 0"81, 

 width of gape 088. 



The example here described seems to be of a nestling female 

 passing over to the intermediate finely striated phase. It is full of 

 blood-feathers. An example, ex Sumatra (^Mas. Brit.) is in similar 

 plumage.

 bold bufFsupercilium, 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 with 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 grej^, 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 scapulars 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, freckled with brown, outer 

 webs being pure white, narrowly bordered with dark brown, and 

 having terminal black spots. Other scapulars pure white traversed 

 sparsely with fine irregular greyish brown lines. Minor and major 

 wing-coverts brown, with rusty margins and having a mottled rusty 

 and brown aspect. Many of the major coverts with pure white ter- 

 minal spots. White and tawny minute terminal spots on many of 

 the other wing-coverts. Tertiaries brown, minutely freckled with 

 pale grey wavy fine lines, tinged with tawny rufous in places. Some 

 with white or greyish white terminal spots. Primaries with the inner 

 webs pale brown ; outer brown, marked with rusty and indented with

 mottled with tawny rust-colour. Axillaries grey, tipped pure white.
