light ; crown nigrescent, and throat dark silvery-ash ; the ear-coverts 

 whitish silvery-ash. The male has the whole under-parts, below the 

 throat and fore-neck, bright yellow, the first five primaries edged with 

 the same ; the secondaries and basal two-thirds of all but the middle pair 

 of rectrices are margined with orange-yellow ; the tertiaries internally 

 with dull white, and most of the great alars have a small white spot at 

 tip. In the females, the lower-parts are merely tinged with yellow, and 

 that of the wings and tail is comparatively very faint. 



Minla cinerea, nobis, n. s. Allied in form and size to M. castaniceps, 

 XIII, 939. Colour olive-grey above, tinged with green ; beneath white, 

 tinged on the flanks with ashy, and shewing some yellow along the mid- 

 dle of the abdomen : a broad yellowish-white supercilium, and over this 

 a black one ; the coronal feathers margined with black, and the cheeks 

 mingled black and white ; orbital feathers subdued white ; wings and 

 tail without markings ; the tertiaries edged with grey, and the second- 

 aries with very faint dull yellowish. Length four inches and a half, of 

 wing two and a quarter, and tail an inch and three-quarters ; bill to 

 gape nearly five-eighths ; and tarse three-quarters of an inch. Probably 

 a female bird. From Darjeeling. 



In XIV, GOO, at the suggestion of Mr. Strickland, I regarded as 

 identical the Ilijpsipetes gracilis, M'Clelland and Horsfield, with 

 Sihia capistrata, (Vig.), v. nigriceps, Hodgson ; but referring since to 

 Dr. M'Clelland's drawing of Sibia gracilis, and more particularly also 

 to the latin diagnosis (P. Z. S. 1839, p. 159), I find that they are 

 decidedly distinct. The following description is taken from the draw- 

 ing of S. gracilis. Above dark non-rufous brown, paler below, and the 

 throat white ; rump and upper tail-coverts ashy ; tail also greyish, with 

 a broad black subterminal band, and broad greyish-white tips ; wings 

 dusky-black, the great coverts partly, and the tertiaries wholly, greyish- 

 white, the latter having a slight dusky subterminal border and white 

 extreme edge. Iris whitish. Bill dusky-black ; and legs dull white. 

 Wing three inches and a half: tail about four inches. Inhabits Assam. 



Leioptila, nobis, n. g. This form serves to connect Sibia, Hodg., 

 as exemplified by S. capistrata, with Yuhina, Hodg. ; but cannot be 

 placed satisfactorily with either. It also much approaches Ixops, Hodg., 

 in general structure, but the legs and toes are much smaller. The bill, 

 too, is more slender, less so than in Yuhina, rather more so than in
