This species should have been included in our paper on Birds 

 from the Northern portion of the Malay Peninsula (Ibis, 1911): 

 specimens were obtained in Trang in October 1909. 

 Molpastes haemorrhous klossi Gyld. 



Molpastes atricapillus klossi, Gyldenstolpe ( Robinson, errore ! ), 

 Bull. Brit. Orn. Club, xli, 1920, p. 12 (North Siam). 



Molpastes atricapillus, A., pp. 322, 516 ( partim ; Tavcy ; Nwalabo ; 

 Shymotee ) ; C. i, p. 199 (partim ; Central Tenasserim ). 



Molpastes haemorrhous chryso7-rhoides, M. 2, p. 387 ( partim : Siam 

 and Tenasserim ). 



It is probable that this bird occurs in our area, as Mr. W. J. 

 F. Williamson has obtained a series from Sriracha on the eastern 

 side of the Inner Gulf of Siam. Baker ( M. 2, p. 387 ) does not 

 admit that Siamese birds differ from the Chinese form, M. h. 

 chrysorrhoides ("Birds from North and Central Siam are also of 

 this race" ), though stating that the Chinese bird has wings ranging 

 from 90 to 111 mm. Gyldenstolpe's type series of twenty-one birds 

 from North Siam have wings 85.5 to 93.4 mm. long, and the wings 

 of six specimens of Williamson's from South Central Siam vary from 

 81 to 88 mm. Hume and Davison's series taken in North Tenas- 

 serim, between Salwin and Tavoy, had wings of 80 to 95 mm.. Gates
