Female. T.L. 108 ; W. 58; T. 48 ; Ts. 18-5; bill from 

 gape 14'5 mm. 



Male slate-colour above (Ridgway), intermediate between 

 deep and dark Payne's grey. Female brownish olive above, 

 slightly modified by the grey bases of the feathers. (The 

 second female is very faintly tinged with slate on the lower 

 back.) 



The male differs from D. h. vulcani Robinson, of Java, in 

 having the abdomen washed with buff; it is much paler than 

 D. h. malayana Grant, of the Malay Peninsula and Sumatra, 

 and has white under tail-coverts. 



The female is brighter below than D. h. vulcani, the 

 throat and abdomen washed with buff (not whitish) and the 

 breast and flanks not iufuscated ; differs from D. h. malayana 

 in being paler and brighter below, lacking infuscatiou on 

 breast and flanks. 



The following key, based on eighty specimens, indicates 



the differences between the Annam and Malayan races ; 



all apparently differ from D. h. hyperythrus of Darjiling in 



being darker and greyer above. No example of the species 



appears to have been met with between Manipur in the 



north-west and Annam and the Malay States in the 



south-east : —
