The above series is very uniform in color, notwithstanding con- 
siderable individual difference in the width of the streaks on the 
throat, and the degree of rufescence on the back. The female is in 
size identical with the male, but is noticeably less rufescent on the 
upper surface, excepting, of course, the pileum. All these specimens 
excepting the type, taken from August 15 to September 15, show 
evidences of molt in progress. Doctor Abbott writes that this was 
a common species on Pulo Riabu, August 18, 1899; on Pulo Jimaja, 
September 17-28, 1899; common in thickets on Pulo Siantan, August 
19 to September 6, 1899; and that it was the commonest bird of any 
kind on Pulo Telaga, September 14-15, 1899. 
Measurements of the entire series are given below.
