Hah. Luzon, January and February [Meyer). 



The adult male (nos. 1, 2) has the back, rump, upper tail-coverts, and wings dull brown, 

 with a bronze-green gloss. The primaries are brown, with a flxint ferruginous fringe to the 

 outer webs, the secondaries with a bolder albescent edging. The head, neck, throat, breast, 

 abdomen, vent, thigh-coverts, and under tail-coverts tawny. The throat, cheeks, and ear-coverts 

 black, and marked as in P.panini. The crest is more elongated than in that species. The 

 rectrices for the first five inches are bronzed brown, followed by a ferruginous band about one 

 inch deep, and terminated by a black band glossed with green of about two inches. A narrow 

 ferruginous fringe terminates some of the rectrices. In the outer pair, and sometimes in the 

 two outer pairs, the ferruginous band is pale tawny, and does not run through the outer webs. ■ 



The adult female (no. 3) has the wings, back, and tail as in the male, the rest of the 

 Tr. Z. S. ix. plumage dull brownish mouse-colour. The quills are not fringed as in the male. The bill in 

 this species is built on the same model as that of P. 'panini ; but there do not appear to be as 

 many grooves in the maxilla, five being the greatest number apparent. 



In a very old male (no. 6), judging by the bill, several new rectrices have come, which have 

 the central band almost white, the colour above and below this band being black glossed with 

 green, and not brown. The remaining old rectrices are as described above. In a very old 

 female example (no. 7) the same peculiarity is to be found. A young male (no. 5) with the 

 casque partially developed, but without lateral plates or grooves, has the rump ferruginous, and 

 the first-plumage rectrices broadly washed with ferruginous at their apex. 



t Measured in a straight line from the nostril to the tip.
