490 Birds of Celebes: Zosteropidae. 



at Rurukan, where they were eagerly searching among the twigs for aphides 

 and the like. The Zostei'opes, according to Dr. Hartlaub (a 1), usually go in 

 small flocks, more rarely alone or in pairs, and feed upon small insects and 

 fruit. Some are known to have a pleasant song. 

 Z. atrifrons is not yet known in South C'elebes.

Zosterops subatrifrons (1) M. & Wg., Abli. Mus. Dresd. 1896, Nr. 2, p. 17. 



"Silel", Peling, native name. 



Adult. Like Z. afrifroiis, but the black of the forehead passing over the cro-wn, the sides 

 of the head brownish ohve (not greenish yellow-olive), the yellow of the throat clearer 

 (not oUve-yelloAv), the breast whiter (not so strongly washed with grey), the upper 

 parts very slightly duller — less of yellow in the olivaceous tint (ad. Peling, V. — Viil. 

 95 — 14535). 



Measurements. Wing 53 — 55 nun; tail c. 41; bill from nosti'il 8; tarsus Ki. 



Distribution. Peling Island (in Dresden and Tring Mus.). 



Among the skins sent by our native hunters from Peling was a series of 

 eight of this local species. It is most like Z. atrifrons of the mainland of 

 Celebes, while Z. delicatula of New Guinea also stands near, but is larger and 

 has the cheeks and throat pure yellow.
