With a very large series before me, I have come to the conclusion that A. malaccensis should be 

 kept separate from four other very closely allied species, two of which I shall describe as new. 



The characters which distinguish the present species from the other closely allied forms are 

 as follows : — The breast is bright yellow in both sexes and at all ages. In the adult male the 

 sides of the head are olive-brown, the throat chocolate-brown glossed with white, a large portion 

 of the greater series of wing-coverts and the scapulars maroon-brown. In the young males the 

 throat is mottled with bright yellow and often with orange, excepting in three specimens which 

 I have examined from Flore*, in which the throat is mottled with white ; but adult males from 

 that island agree perfectly with specimens from Malacca and Borneo. 



I have examined a female from Cambodia, and adult males from all the localities above 

 enumerated. 



Messrs. Hume and Davison write to me : — " Akiab, in Arracan, whence we have recently 

 received specimens, is, so far as we yet know, the most northern limit attained by this species. 

 We have not received it from Pegu ; nor have we observed it in any part of Tenasserim north 

 of Moulmein. In fact our first specimens were obtained at Amherst ; thence southward, 

 until Mergui is reached, the species must be accounted rare. Southward of Mergui, along the
