Variation. The specimen from Bonerate has a remarkably long tarsus. Hartert (14) con- 
siders his specimens from the Lesser Sunda Islands “mostly distinctly larger, with 
slightly larger beaks". 
Egg. Rounded ovate, glossless whity blue, 15 X 13 mm (S. Celebes: Ribbe & Kiihn — 
C 7996). 
Nest. Two, South Celebes (Ribbe & Kiihn, Nrs. 1552— 53), light, shallow cup-shaped structures, 
calling to mind the nests of Sylvia cmTuca’ and cimrea, externally of grasses, with 
plant-wmol interwoven, lined with fine planLfibres; size: 65 diam. X 45 mm depth, and 
65 X 35; cup inside: 45 diam. X 30 — 35 depth. 
Distribution. South and West Celebes: — Macassar (Wallace i, Meyer 5, Weber 10, 
P. & P. Sarasin), Maros (Guillem. 9), Bonthain Mts. (Everett 13, Doherty 
14], Sosso, S. W. Central Celebes (P. & E. Sarasin 12), West Celebes (Doherty J4); 
Bonerate Id. (P. & F. S. 12]-, Saleyer, Djampea and Kalao (Everett 13)] Lombok 
(Wallace etc. 1, 8, 11, 13); Sumbawa (Doherty 13); Ternate (Wallace 8, Beccari 7). 
In Celebes this White-eye has as yet been recorded only from the South 
and West, and from the islands between the South and Flores, and its peculiar 
distribution is suggestive of its having recently spread its range by flight from 
Lombok or Ternate. On one side it is closely related to Zosterops flava (Horsf.) 
of Sumatra, Java and Borneo, a species distinguishable according to Salvadori 
(6) by its larger size, its having more yellow on the forehead, less on the upper 
tail-coverts, the rump not brighter than the back, the black subocular streak 
not extending so far forward, the bill small and delicate; in the Moluccas, 
Z. buruensis Salvad. of Buru seems from the description to be very like the 
young Z. intermedia, differing from the adult by its duller and duskier upper- 
and paler under-surface; while Z. intermedia is said to differ from Z. chloris Bp. 
of Banda, another very near ally, by being “of a greener shade, with the under- 
parts purer and more sulphur- yellow” (Sharpe 8). Zosterops bnmneicauda 
Salvad. of Ceram Laut, Choor, and Aru is held by Hartert to differ by its 
quite black bill and more olive flanks.
