This very distinct subspecies is the most greenish of all the forms 

 of Microtarsus atriceps. It differs from Microtarsus atriceps cJiryso- 

 pliorus,^ of South Pagi Island, western Sumatra, as it does from 

 Microtarsus atriceps atriceps, though even more markedly; and from 

 Microtarsus atriceps Jiypercmnus^ of Simalur Island, western Sumatra, 

 in much the same way as well as additionally in much slenderer biU. 



Doctor Abbott obtained two adult specimens, male and female, in 

 perfect plumage. The female is practically identical with the male. 

 The measurements of both are given below:
