2.5. Aethopyga siparaja (Riiffl.) (Nov. Zool. I. ]). 47.')). 



Several speciiueus both from Buuguran and Pulu Laut. Tliey clearlj- show 

 that the moulting time for this bird i^ from Jnly to September. A specimen shot 

 iu .July is very pale above, such as I never saw any before, but a dark red feather 

 begins to appear here and there. Some specimens killed iu Se])tember are out of 

 the moult already, and are of a beautiful deep colour. A young niale, also September 

 (Pulu Laut), has a few scarlet feathers here and there in the brownish green 

 2)lumage. 



2(). Araclinothera longirostris (Lath.) (Nov. Zool. I. [>. 47.3). 

 Bunguran. 



*27. Munia fuscans (Cass.) (?). 



One cpiite yonugj'i'malr from Bnugarau. It is sooty brown above and below, 

 the under wing-coverts buff, the belly slightly mottled with brownish grey. It is 

 such a young bird, not yet long out of nest, that identification is difficult, but I 

 think it is the 3Iunia fuscans, although the bill is exceedingly small, even for such 

 a }'oung bird, the culmen only measuring 0-8.5 cm. Material of adult birds may 

 j)rove it to be a distinct form. Only recorded from Borneo. 



*2S. Munia atricapilla brunneiceps Waldeu. 



Several examples of both sexes from Bunguran belong undoubtedly to the 

 Bornean form of the Rufous-and-Black Munia. I consider the nomenclature used 

 above the most appropriate form of naming this bird. It is, as Sharpe, Cat. B. XII. 

 p. 338, justly says, similar to M. nfricajHlla, and apparently without any grey 

 mottling on the back. The head is sooty black or dusky chocolate, slightly browner 

 on the hinder neck and nape. These difJ'ereuces are not great, but clear enough for 

 the scrutinising eye of an ornithologist ; therefore one could not much be blamed 

 if one should treat ^f. hrunnnccpa simj)ly as a distinct species ; but if it is a sub- 

 species I should rather place it nearest to M. atricapilla than to M. jagori from 

 Luzon, which has a different colour on the rump and upper tail-coverts. 



Sharpe, Cat. B. XII. p. 335, does not separate the Himalayan and the 

 Malaccan form of M. atricapilla, on account of the many intermediate specimens. 

 To me it seems that all tlie intermediate forms come from the countries between 

 those inhabited by the northern and the southern forms in extremis, and therefore 

 I would treat M. rubronigra of North India as a subspecies. 



29. Artamus leucogaster (Valenc.) (Nov. Zool. I. p. 475). 

 A number from Bunguran. 



3i.i. Caloruis chalybea (llurnl'.) (Nov. Zool. 1. [i. 47()). 



A series from Buugui-au and Pulu LaiU. They are exactly like the Sirhassen 

 specimens. 



31. Dissemiinis platurus Vieill.; (Nov. Zool. I. p. 47()). 

 A large series from Bunguran.
