phaioceps, but to have the head less brown, the pale margins 

 of the throat-feathers broader and more conspicuous, and 

 to be brighter and larger ; a specimen from Chiengmai, 

 northern Siara, agrees. All birds I have seen from Indo- 

 China (Assam to Siara north of the Malay Peninsula) are 

 oi phaioceps section, having the wing-shafts unblackened. 



One more race of Micropternus may well be distinguished : 

 of it Hume writes {loc. cit. supra), " When you go towards 

 the extreme western limits of the species in the Kumaon 

 Bhabur, northern Rohilkund, the Dhoon, etc., you come 

 upon a huge race almost more distinct from phaioceps than 

 the latter is from hrachyurus. 



" It is characterized not only by its size but by the almost 

 entire absence of infuscation on the head, and by the fact 

 that the adults are not only absolutely immaculate below, 

 hut also lose all markings on the upper surface, on the back, 

 scapulars, and rump, which, coupled with the bright chestnut 

 of their plumage, gives them a very different appearance 

 from all the other races o^ phaioceps." 



For this race I suggest the name 



Micropternus hrachyurus humei, subsp. nov.

In a series of twenty adult examples of 2\ javanensis from 

 the Malay Peninsula, south of Lat. 10° N., the wing-length 

 varies from 125 to 136 mm. Three specimens from southern 

 Johore and one from Bintang I., Rhio Archipelago, have
