226 TIMELnD^. 



Adult male. General colour above clear ashy grey ; the crown, 

 sides of head, including the cheeks, ear-coverts, and chin bright 

 cinnamon-rufous, the hinder crown and occiput gradually shading 

 off into brown as they approach the hind neck ; throat, neck, and 

 underparts generally ashy grey; the centre of the abdomen and 

 under tail-coverts pure white ; thighs deep cinnamon-rufous ; under 

 wing-coverts washed with rufous, as also is the edge of the wing ; 

 lower surface of quills dark brown, edged along the inner web with 

 rufous white ; wings above brown, somewhat washed with olive 

 and not so grey as the back, the primaries narrowly edged with 

 whity brown ; tail light brown, with paler brown margins, the 

 outer feathers tipped with white, before which is a tolerably distinct 

 subterminal bar of dark brown ; bill in skin light hoin-brown, the 

 under mandible paler and more yellowish; "legs pale warm 

 brown ; iris naples yellow " (A. Everett). Total length 4-7 inches, 

 culmen 0-55, wing 1-85, tail 1-75, tarsus 0-75. 



Female. Differs from the adult male in being white below, without 

 the grey throat, although indications of the latter are generally 

 seen in the greyish shade more or less observable on the lower 

 throat and sides of breast. The cinnamon-colour of the chin is also 

 difficult to trace, being so faintly pronounced. 



Ohs. In my opinion 0. homeonensis, Salvad., is the fully adult 

 male, and 0. cineraceus the female of the present species. The 

 only female in the Museum, so determined by dissection, is a 

 Lombock skin of Mr. Wallace's, and this is whitish below; both 

 grey- and white-breasted birds have also occurred together in the 

 Bornean collections of Mr. Motley (Banjermassing) and Mr. Hugh 

 Low (N.W, Borneo). I feel the more certain, therefore, that the 

 white-breasted birds are adult females, and not young birds, as 

 we have specimens of the latter in the Museum from Banjermassing, 

 and they are different from the adult, resembling much more 0. sepium 

 in appearance. 



Young. General colour above olive-brown : quills brown, exter- 

 nally washed with olive-green ; tail brown, tipped obscurely with 

 whity brown, with a subterminal shade of black, scarcely forming 

 a spot ; ear-coverts pale rufescent ; under surface of body dull 

 yellowish white, the thighs obscure fawn-colour ; centre of the 

 body pale yellowish, the sides of the breast and flanks obscurely 

 washed with greenish. 



Hah. The islands of Sumatra and Borneo, extending also into 

 the Malayan peninsula. Count Salvadori considers that the Suma- 

 tran bird is the same as the Bornean (0. homeonensis, Salvad.). I 

 ao'ree with Lord Tweeddale, however, that neither can be separated 

 from the Malaccan.
