Mr. Hartert (15) remarks that the wings of his two examples from Saleyer 
Island are only 49 — 50 mm long, and they are slightly paler, “though this latter 
character is probably due to their being in worn 23lumage”. 
Distribution. Celebes — Macassar (Meyer 1 , in Berhn and Dresd. Mus., P. & F. Sarasin); 
Bonthain Mountains (P. & F. Sarasin, Everett 14, Dolierty 15); Luwu at the 
head of the Gulf of Boni (Weber 12 ); Kandari, S. E. Celebes (Beccari 3 ); Lake 
Posso, Central Celebes (P. & F. Sarasin); Dongala and Tawaya, W. Celebes 
(Doherty 15). 
This was one of Meyer’s discoveries in South Celebes. No specimens 
of this species have as yet been obtained in North Celebes, and the bird is 
somewhat rare in collections. It is most nearly allied to G. sahadorii Biittik. 
of Borneo, or perhaps to the Sooloo form, in which Dr. Guillemard points 
out some distinguishing characters. The Borneo form was at fh'st united by 
Dr. Sharpe with G. Jlaveola, hut, in separating it as G. sahadorii, Mr. Biitti- 
kofer (11) calls attention to its smaller size, the sides of the breast olive-brown 
instead of yellow, its wanting the whitish lores and the yellowish wash on the 
ear-coverts, the upper surface a shade darker, the white near the ends of the 
inner webs of the tail-feathers, forming much larger spots. 
Another ally is Salvadori’s Gerygone modiglianii of Sumatra (8), which 
Sharpe considers identical with Davison’s G. pectoralis of the Malay Peninsula 
(Ibis 1892, 99; 1893, 119, 561) and which, in his opinion, is questionably distinct 
from the Bornean form of Biittikofer. From G. flaveola, as Salvadori points
