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.
