 A careful re-examination of this series and seven others 

 from Sumatra and over twenty from the Malay Peninsula 

 shows that no separation of the Sumatran bird is possible.

[Xos. 886, 887]. 

 Wing, 3, 83; 2, 75, 73 mm. 



These specimens seem slightly smaller than the Malayan 

 specimens but the series available is not sufficiently large to 

 decide if the Sumatran bird is subspecifically distinct. If so 

 it will have to be known as A. a. concolor, Sehlegel.
