﻿360 MEARNS. 



margined with jet black inclosing a sharply pointed white spot; middle of ab- 

 domen, white; crissum white, faintly washed with buff which is strongest on the 

 lower tail-coverts; under side of wing-quills broadly white on inner border at 

 base; edge of wing, white; axillars, white at base, broadly black at tip; under 

 wing-coverts, black, tipped with white and pale cream color; upper wing-coverts 

 without white spots. 



Measurement of type (from skin). — Length, 230; wing, 125; tail, 78; culmen 

 (chord), 25; bill from nostril, 19; tarsus, 32; middle toe with its claw, 30. 



This species was occasionally seen as it darted through the mossy forest or 

 alighted upon the ground; but it was so shy that only a single specimen was 

 shot, although its loud, sweet song was frequently heard at morning and evening. 

 It is closely related to Geocichla andromeda (Temminck), which Mr. Walter Good- 

 fellow has recently (February, 1905) discovered at 8,000 feet on Mount Apo, 

 Mindanao, as recorded by Mr. W. R. Ogilvie-Grant, in the Ibis for July, 1906, 

 pages 468 and 477. 



Zosterops halconensis, sp. nov. 



Mount Halcon silver-eye. 



Type. — No. 14480, Mearns collection. Adult male from Mount Halcon, Min- 

 doro, Philippine Islands, at the altitude of 4,500 feet, November 14, 1906. 



Remarks. — In the Bulletin of the British Ornithologists' Club, vol. XIV, page 

 13, October 30, 1903, Mr. Ernst Hartert separated the mountain Zosterops from 

 Lepanto, Island of Luzon from the lowland Zosterops meyeni Bonaparte, under the 

 name Zosterops ivhiteheadi, and, in the same paper (page 14) described the 

 mountain form from 8,000 feet on Mount Apo, Mindanao, as Zosterops ivhiteheadi 

 vulcani, observing that the form vulcani evidently represented Zosterops whiteheadi 

 ivhiteheadi "on Mt. Apo, but probably older forms will also come as subspecies 

 into this group, so that its name — that is, that of the species — may have to be 

 altered eventually." 



In addition to the forms ivhiteheadi and vulcani, which are represented by 

 large series in my collections, the form here described was obtained in the Min- 

 doro highlands. 



Characters. — Sexes alike. Similar to Zosterops vulcani, but slightly larger. 

 Wing, 56 against 55 millimeters; tail, 42-41; culmen 12-11.5. Color yellower, 

 but without a longitudinal yellow stripe on middle of abdomen; sides more 

 whitish gray; cheeks and ear-coverts paler and yellower, but the yellow con- 

 fined to the chin and throat, not suffusing the upper chest; upper surfaces of a 

 more golden green. 



From Zosterops ivhiteheadi the Mindoro form is easily distinguished, when 

 similar seasonal plumages are compared, by its greater size and more yellow 

 coloration.
