 arisen.

Birds from Sarawak and Borneo measure : — 



Wing, 3, 91; $, 86, 85. 



The Bornean birds have been separated by Hesse as Mig- 

 lyptes tristis micropterus (Ornith. Monatsb. XIX, p. 182 

 (1911), as having the wing shorter, 85-96 mm. as against 

 95-103.5 in the typical form which was described from the 

 Malay Peninsula. The distinction is fine but the above 

 measurements tend to confirm it.
