Of this very distinct new species, one J and one 5 were procured on the island 

 of Bunguran, on the .jth and 7th of October. 



Stuch//-is nfitune/is/s forms somewhat an intermediate species between St. nigri- 

 cejjs, which e.\teuds from Nepal and Bootan, through all the hill-tracts of Assam, and 

 south of the Brahmaputra to Arrakan, Pegu, and Tenasserim, and (SV. hoi-ncensis, a 

 discovery of Mr. Whitehead, and as yet oidy found on the Kiaa Balu, Dulit, Poeh, 

 and Peurisen Mountains in Northern Borneo. 



The Bunguran birds differ from St. iiigiiceps in the colour of the throat, which 

 is more uniform and darker, in the feathers on the forehead being hoary grey with 

 black shafts, instead of black with white edges as in St. nii/ricej/.s. Besides the 

 feathers of St. nigriceps on the throat are much more pointed, while they are rounded 

 in St. natunensis and bornee.nsis. The bill is, in the two skins from Bunguran, 

 black, while it is brown with a lighter mandible in the skins from Sikkim. Gates 

 (Fiiiiii. Brit. Ind., B. i., p. 102) gives the colour of the bill oi St. nigriceps as "bluish 

 black, lower mandible pale bluish," but Hume states that the colour of the bill 

 changes according to season, and that it is pale, with the lower mandible pale 

 yellowish horny, in the cold season (November to February), while it is darker in 

 summer. However this may be, the bills of all the specimens of St. nigriceps before 

 me have the bills brown and the lower maudilile quite pale (in skin), while in St. 

 natunensis and St. borneensis it is black in skin, and in a ? of St. nigriceps which I 

 shot in the hills south of the Dihing River in Assam, on August 28th, 1888, I found 

 the upper mandible horny brown, the lower bluish flesh colour (cf. also Sharpe, 

 Itm., 1887, p. 449). There is a fatal misprint, 1 suppose, in Sharpe's careful and 

 exact description (/.c), as the bastard-wing and wing-coverts arc descrilu'd as blue, 

 instead of olive brown. 



There are twci UKire forms which may be confounded with St. natunensis — i.e., 

 first St. lanata (Bp.) from JSumatra, which is much more rufous above uud below
