214 VISCOUNT WALDEN ON THE BIRDS 
A fourth Guimaras individual (female, jide 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.

Hab. Luzon (Meyer). 
No difference between the sexes as determined by Dr. Meyer. The young bird was 
described as distinct by Prince Bonaparte, and the adult and young severally made the 
type of separate genera. 
A Luzon example of Ptilopus jambu (Gm.) is stated by Professor Schlegel to be 
contained in the Leyden Museum (Mus. Pays-Bas, Columbe p. 36). The correctness 
of the attributed habitat requires confirmation.
