" Male vix ad. Iris dark ; bill black, whitish at tip ; feet flesh. 

 Female ad. Iris dark hazel ; upper mandible dark horn, lower 

 reddish ; feet flesh. 



The males above cited, and two others from Pahang, are all 

 very neai'lj'^ adult though two have pale tips to the bill : they differ 

 from a male from Saribas, S. W. Sarawak, in having the flanks more 

 or less washed with rufous and the blue tips to the feathers of the 

 crown and wing coverts more conspicuous. The Bornean bird is, 

 however, an extremely adult one and we do not think that it would 

 be wise to admit A. nigricans Blyth^ founded on a female, as a 

 mainland race of A. euryzona.
