378 Viscount Walden on a 



quill is about two-thirds of the length of the second ; this is half 

 an inch shorter than the third, which, again, is nearly as much 

 shorter than the fourth. The fourth quill is longest and slightly 

 exceeds the fifth, the sixth being somewhat longer than the 

 third. 



An example, labelled a female, obtained by Mr. Wallace at 

 Sarawak, and now in his collection, has the under plumage 

 hardly tinted with yellow, the under tail-coverts nearly pure 

 white, and the breast-feathers more decidedly brown. It ex- 

 hibits also a distinct black stripe below each cheek. 



Another example ( $ fide Wallace), also obtained at Sarawak, 

 and now in my collection, diflfers by having the upper plumage 

 of a lighter shade of brown, the under plumage more or less 

 pure white, and the bill shorter. 



Notwithstanding the difference of colouring exhibited by these 

 three individuals, I do not doubt that they belong to the same 

 species. Generally they agree so well with the description given 

 by Lesson (/. c.) of S. criniger that, unless the Bornean is a 

 representative form, it will in all likelihood prove to be the 

 same as that hitherto unidentified Sumatran species. I suspect 

 that this is also the type of Trichophuropsis, Bp., T. typus, Bp., 

 Compt. Bend. vol. xxxviii. p. 59, "Borneo" (1854). 



Brochypus criniger, A. Hay (/. c.) ex Malacca, is a totally 

 distinct species. It is a small bird (wing 2g inches), with the 

 bill of an Alcippe. Underneath it is bright yellow, above ferru- 

 ginous olive. The rectx'ices are pale ferruginous, with obscure 

 pale yellow tips. Mr. Blyth has identified Criniger sericea, 

 Miiller, Mus. Lugd., with this species (Ibis, 1865, p. 48); 

 Mr. AVallace obtained it at Sarawak. It is probably Tricho- 

 phoropsis viridis, Bp. (/. c), "Borneo" (1854), and Trichophurus 

 minutus, Hartl. J. fur 0. 1853, p. 156, "Malacca" {conf. 0. 

 Finsch, J. fiirO. 1867, p. 19).
