214 VISCOUNT WALDEN ON THE BIEDS 



A fourth Guimaras individual (female, fide Meyer) has the plumage still more 

 intensely green than the last ; the bluish grey of the forehead is less distinct, and the 

 uniform deep green of the breast is only broken by a faint indication of dark purple . 

 at the tips of two or three feathers. The under tail-coverts are mostly pale cinnamon. 

 In all five examples the mandible is carmine at its base, the remainder of the bill 

 yellow, the feet carmine. 



It is probable that in the young birds the head and breast are green, and that the 

 dark purple pectoral patches are rudimentary indications of the broad pectoral band of 

 the adult. As in Leucotreron gularis, of which this Philippine species is a beautiful 

 representative form, the first primary is abruptly attenuated near the end.

No difi'erence between the sexes as determined by Dr. Meyer. The young bu-d was 

 described as distinct by Prince Bonaparte, and the adult and young severally made the 

 type of separate genera. 



A Luzon example of Ptilopus jamhu (Gm.) is stated by Professor Schlegel to be 

 contained in the Leyden Museum (Mus. Pays-Bas, Columbm p. 36). The correctness 

 of the attributed habitat requires confirmation.
