Birds of Celebes: Oypselidae. 
335 
Breeding season. Dr. Hickson (5) found this species and C. breeding in countless 
numbers in two caves at Tanjong Arcs, Talissi Island, North Celebes on August 
28^’^. In Amboina Dr. Platen collected quantities of eggs on July 23’^'^, 1881. 
Distribution. Celebes — Talissi Island (Duillem. 4, Hickson 5), Strait of Lembeh (Meyer 2), 
Minahassa (P. & F. Sarasin), Macassar (Wallace 1, 7), Maros (Guillem. 4), Bontbain 
(Everett i5); Peling and Banggai (Nat. Coll.); Moluccas and Papuasia as far as the 
Solomon Islands (Salvad. 4, 6) to Cape York, Australia (Hartert 7). 
This species has a more southern range than C. fuciphaga^ from which it 
may be distinguished by its white abdomen and somewhat smaller size. 
As is proved by the thickness of the guano deposits (see preceding ar- 
ticle) these birds have evidently tenanted certain caves for enormous periods, 
and it is not surprising that this species seems to vary locally or even 
“troglodytically”; for instance the specimens from Peling and Banggai examined 
by us were very small.

Diagnosis. Distinguishable from C. fuciphaga by its having a grey or dusky white band 
across the rump, from C. esculenta by its having no white on the abdomen, and by 
its larger size. 
Measurements. Wing 111 — 114 mm; tail 53 (Hartert 3).

Distribution. Burmah, through the Philippines and the East Indian Islands to North Australia,

In the Celebesian area: Djampea Island (Everett 5). 
Quite recently Mr. Hartert was able to record two fully feathered nestlings 
and a number of nests and eggs from Djampea between Celebes and Flores, 
which he ascribes to this species. It has not as yet been recorded from the
