396 Mr. J. Whitehead on Birds 



1st of May contained a white egg, which was unfortunately 

 broken before she was skinned. 



Iris yellow; bare skin on face king's yellow; upper 

 mandible pea-green, orange spot at base; lower man- 

 dible yellowish green, at tip pea-green, base orange; feet 

 yellow. 



268. Cacatua h^maturopygia (P. L. S. Miiller), (Grant, 

 Ibis, 1895, p. 263; 1896, pp. 475, 560; 1897, p. 248.) 



Met with throughout the entire archipelago, but, curiously 

 enough, we never noticed a single Cockatoo in the valley of 

 the Rio Grande. During our expedition to the Province of 

 Isabella, the natives told me that this species was not known 

 to them ; and also during my trip to Cape Engano, in the 

 north-east of Luzon, we found it absent. So perhaps the 

 species does not pass the high mountains which divide Luzon 

 at 16° longitude. 



269. Pbioniturus DiscuRus (Vieill.). (Grant, Ibis, 1895, 

 p. 263; 1896, p. 560; 1897, p. 248.) 



Met with by us in Catanduanes, Samar, Leite, and Negros. 

 The habits of all the members of this genus are very similar ; 

 they are more often noticed on the wing, flying swiftly over 

 the forest at great heights, uttering shrill screeches, than when 

 perched quietly among the green leaves of the high trees, in 

 which they move with slow deliberation. They nest often 

 in large colonies in old tree-trunks, which remain standing 

 for years in the native clearings ; these trees are of great 

 height and riddled with the borings of various Woodpeckers, 

 more especially of the species of Thrijionax. 



Iris black ; bill and feet bluish white. 



270. Prioniturusmindorensis Steere. (Grant, Ibis 1896, 

 p. 475.) 



Fairly common in the forests of Mindoro, my specimens 

 having been obtained on Monte Dulangan, at an altitude of 

 nearly 5000 feet. 



Iris stone-grey ; bill white, with a bluish tinge ; feet 

 greyish green.
