NILS GYLDENSTOLPE, MALAYAN BIRDS AND MAMMALS. 9 



northern form and 31. atricajnUa hninneiceps Wald. from 

 Borneo. In this latter form the coloiir of the head is dark 

 chocolate while in rubonigra it is perfectly black with a glossy 

 tinge. The northern form is also somewhat larger. 



7 Anthreptes malacensis Scor. — 1 ^ ^V^ 1915; 1 ef 

 1^5 1915; 2 ? 'I: 1915; 1 9 ''A l^l^i 1 ? '/^ 1915. This 

 beautiful Sunbird may be divided into two different races : 

 one western one (typical malacensis) and one eastern one (^. 

 malacensis cJilorogaster Sharpe.). The latter race, which in- 

 habits the Philippines, Celebes, Palawan and Flores, may 

 always be distinguished by its greater size and brighter 

 colouring. The Malayan bird, as well as those from Java, all 

 belong to the typical race while those from Palawan in the 

 collections of the R. Natural History Museum in Stockholm 

 show more affinities to the eastern larger race, na med A. 

 chlorogaster by Sharpe. 



8. Anthreptes hyposrammica S. Mull. — A single 

 female specimen was obtained on the 13th of April 1914. 

 Wing = 64 mm. This species does not seem to extend further 

 north than to Lat. N. 10'" and one of the most northern 

 localities seems to be in the Siamese Province of Bandon, 

 Avhere a single specimen was obtained at Kao Nawng by 

 RoBiNSON and Kloss 1913. 



9. Arachiiotliera robusta Mull. & Schleg. — 1 c? -A 

 1915; 1 (} ^^5 1915. Iris: brown. This fine species is very 

 similar to Arachnothera crassirostris Reichenb. which inhabits 

 the same countries but it may always be distinguished from 

 that species by having the throat and upper breast tinged 

 with olive and with brownish-olive central streaks to the 

 feathers. 



10. Arachnothera modesta Eyton. — 1 c? ^Vi 191^. 

 Iris: brown. Wing: 85 mm. Culmen: 33,5 mm. This species 

 or rather subspecies of Arachnothera affinis Horsf. inhabits 

 the whole of the Malay Peninsula, where it seems to be very 

 abundant. As a rule northern specimens seems to be larger 

 than southern ones but in this species the northern birds are 

 smaller and have been named Arachnothera afjinis. 



11. Leptocoma hasselti Temm. — 1 c? 7^ 1915; 1 J"
