Adult male. Closely resembles the male of P. faseiatus, from 

 which it only differs in the marking of the greater secondary and 

 inner median coverts, which, instead of being barred alternately 

 with wide distinct bars of white and grey and widely margined with 

 yellowish buff, are yellowish buff, with a black bar narrowly edged 

 on either side with white across the external third of each feather. 

 Tail of 16 feathers. Total length 10-2 inches, wing 7-1, tail 3-3, 

 tarsus 0-95. 



An immature male differs from the adult in having the back and 

 sides of the neck still barred and the sides of the throat spotted like 

 the female, while the pectoral band is only partially apparent on the 

 right side, and the primaries are widely tipped with buff mottled 

 with black. 



Adult female. Differs from that of P. faseiatus in having the front 

 of the neck and the chest uniform buii without black bars ; other- 

 wise the plumage is nearly similar, except that the black bars on 

 the scapulars are wider and less numerous and the greater secondary 

 coverts and outer median coverts have a black bar across the last 

 third, as in the male, but the white margins are wanting. Total 

 length 10-1 inches, wing 6-8, tail 3-1, tarsus 0-95. 



In less mature specimens many of the feathers of the chest have 

 a narrow subterminal black band, showing an approach to the 

 adult female of P. faseiatus.
