sixth primaries edged albescent. An old Surigao male has the thigh- 

 coverts, ventral region, and under tail-coverts pale rufous, and most 

 of the upper tail-coverts as in P. panini, otherwise as in typical P. 

 affinis. In a Butuan and a Surigao male the middle pair of rec- 

 trices, with the exception of the basal black band, are rufous through- 

 out, the normal black terminal band being only indicated by black 

 blotches. The new rectrices are pale fulvous white instead of fer- 

 ruginous when they first come in. The number of grooves on the 

 mandible varies from three to four. The extreme altitude of the 

 bill, ending at the nostril, is 1*06, whereas in P. panini it is 1'37.
