Wings and tail with a slight greenish sheen. Axillaries 

 grey like the breast ; the under wing-coverts mingled grey, 

 dusky, and whitish. A patch of white on the inner webs 

 of the 3rd, 4th, and 5th primaries. Wings and tail with 

 a greenish gloss. 



On account of its size and general coloration this bird 

 only seems to need comparison with V. lugubris Sundev. 

 (= melaschistus Hodgs.) and with V. intermedia Hume, Avhich 

 is probably the south-eastern representative of the other. 

 (All that can be gathered from Hume's description of 

 intermedius is that it is paler than lugubris, and that the 

 difference in length between the inner and outer tail-feathers 

 is greater, while the white tips are also larger; the size is 

 about the same. It is therefore a bird with grey under 

 tail-coverts. The types came from the hills of Tenasserim, 

 and it extends northward to Pegu.) 



V. keratensis is clearly distinguished from both by the 

 possession of white, instead of grey, under tail-coverts. 

 In V. innominata Oates the under tail-coverts are ashy. 

 V. saturata from Hainan is rather smaller and has, at most, 

 only the longest under tail- coverts tipped with white ; 

 V. melanoptera Riipp. (= avensis Blyth?) and V. neglecia 

 Hume have white under tail-coverts, but are smaller birds.
