" It was my kind friend Mr. J. H. Gurney, who some months 

 ago shewed me a specimen of this Microkierax from Borneo, 

 and drew my attention to its broad white forehead as probably 

 indicating a distinct species. On examining our series, how- 

 ever, I found that there were several specimens in the Museum 

 from Borneo wiiich were inseparable from the true M fringil- 

 larius of Malacca, and I hesitated to separate the white-fronted 

 bird on the strength of a simple specimen. Now, however, that 

 Mr. Treacher sends four specimens, all of them precisely 

 similar, it is impossible to resist the conclusion that the species 

 is really distinct. It will probably prove to be confined to the 

 north-western district of the island, as the birds presented to 

 the Museum by Rajah Brooke from Sarawak are not to be dis- 

 tinguished from the ordinary Malacean type. Three of Mr. 

 Treacher's specimens are from the Lawas river, and one from 

 Lurabidan. Grovernor Ussher also procured two in the latter 

 province.'"' 



Mr. F. Nicholson, in his notes on some birds from Western 

 Java, Ibis, April, 1879, p. 167, proposes the name buoctoni 

 for Zosterops lateralis, Hartlaub. This name, however, cannot 

 stand. In June, 1878, " S. F.,'' VI., 519, I proposed tho 

 name auriventer for this species. Further references to it will 

 be found in Vol. VII., p. 452, and Vol. VIII., p. 163. 



The species will, I believe, have to stand as Zosterops 



AURIVENTER, Nohis. 



Another note of Mr. F. Nicholson's is important as showing 

 that the species which we have hitherto identified as Miglyptes 

 tristis from Teuasserim and the Malay Peninsula, should proba- 

 bly stand as M. grammithorax, Malherbe. Mr. Nicholson says : — 



'^ Miglyptes tristis, Horsfield, Tr. Linn. Soc. XIIL, p. 177. 

 A pair of birds, concerning which a few remarks are necessary. 

 I compared them with the series of Miglyptes in the British 

 Museum ; and I cannot allow that, if as seems certain, I 

 liave before me the true M, tristis of Horsfield, the Malacean 

 and Bornean birds usually called M. tristis are really the same 

 as the Javan species. The latter has a totally black under 



* As figured, the bird has not only the forehead, but quite the anterior two-thirds 

 of the crown, pure white. — A . O. B,
