 Hah. Luzon, Guimaras {Meyer). 



In the adult plumage this species has the entire head, neck, and upper breast pale ashy 

 white, the occiput and nape being faintly washed with light green. Bordering the "-rcy of the 

 breast and intervening between it and the ashy green of the lower parts is a broad dark purple 

 band, rather deeper in the middle than at the sides. The under tail-coverts are cinnamon-colour. 

 The under surface of the rectrices is slate-colour, with a broad terminal almost white band 

 which above appears yellow ; the chin and throat and the space before the eye black ; remainder 

 of the upper plumage bright rich green, with a golden gloss in certain lights. From a Guimaras 

 example, noted as a male by Dr. Meyer. 



Another male example from Luzon has the abdominal region of a still more ashy creen, 

 some of the ventral plumage being tawny. An individual from Guimaras, and noted a female, 

 has the abdominal region deep green, and the dark purple pectoral band is represented by a 

 large triangular patch of the same colour, a few purple feathers on each side only indicating the 

 position of the band. The pale ashy white of the nape is more deeply tinged with o-reen. 

 Another Guimaras female {Jide Meyer) has the head, nape, and breast green, the forehead alone 

 being bluish grey ; the abdomen is mixed tawny ashy green ; on the breast is a limited purple 

 triangular patch. This individual resembles very nearly the figure in ' The Ibis ' {I. s. c.), only 

 that in the plate by Jennens the purple patch is represented much too low down, and the under 

 tail-coverts are not dark enough. It also agrees well with the description given by Professor 

 Schlegel {I. c). 



A fourth Guimaras individual (female, fide Meyer) has the plumage still more intensely Tr Z S i 

 green than the last ; the bluish grey of the forehead is less distinct, and the uniform deep oreen P- -'^''• 

 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.
