Birds of Celebes: Cacatuidae. 
Distribution. Celebes and Bnton — Tomini (Borsten c 2), Paguatt, Tomini Gulf (Posenb. 
c 6, Meyer c 10], Posso, Tomini Gulf (Meyer c 10), Kandari, S. E. Celebes (Beccari 
c 7), Birton (Labillardifere b 1, vS. Milller a 2), Maros, S. Celebes (Weber c 16], 
Mandalb, W. Coast (Meyer c 10], Maroneng (P. & F. Sarasin), Dongala and Ta- 
waya, W. Coast (Doherty c 20), Kwandang, N. Coast, and the small islands in 
Kwandang Bay (Meyer c 10, Rosenb. c 6, e 9), Biiol (P. & F. Sarasin). 
2. C. sulphurea djampeana Hartert. 
Nov. Zool. 1897, 164. 
h. Caeatua sulphurea (1) Hart, Nov. Zool. 1896, 176. 
Diagnosis. Exactly like the tyincal C. sulphurea of Celebes, but with a smaller beak 
measured straight from the outer margin of the cere, where maxilla and mandible 
meet, to the tip ■ — in two examples 24 mm, in one only 23.5, as against 27 mm in 
females from Celebes (Hartert 1. c.). 
Distribution. Djampea Island (Everett h 1). 
3. C. sulphurea parvula (Bp.). 
For synonymy, etc. cf. Salvador!, Cat. B. XX. 1891, 120. 
Diagnosis. Similar to the typical C. sulphurea, of Celebes, but the ear-coverts paler and 
much less yellow (Hartert). 
Distribution. Lombok, Sumbawa, Flores, Semao, Timor. 
Observation. We cannot regard Mr. Hartert’s dfrdsion as conclusive; if one were only to 
investigate closely enough further racial peculiarities would no doubt be found. 
The distribution of Caeatua sulphurea in Celebes is a remarkably interrupted 
one. In the Minahassa it is unknown as a wild bird, as it is also at Macassar 
and Maros in the South; this also appears to be the case at Gorontalo, though 
it is to be met with on the coast of the gulf at Paguatt and Posso, as also 
twenty miles from Gorontalo at Kwandang on the north coast, and again 
further west at Buol. At Posso, on the south shore of the Gulf of Tomini, 
Meyer first met with it in large flocks; but on the same coast further east at 
Todjo it was not then to be found, neither does it appear to occur on the 
Togian Islands'). Labillardiere in one of the early French voyages was the 
first to notice it at Buton Island; afterwards Salomon Muller saw it in large 
numbers there: “Before nearly all the houses we saw Cockatoos and other species 
of parrots fastened by a small double ring of buffalo-horn or cocoa-nut on one 
foot to sticks, etc.”; Psittacus sulphureus was most abundant, in much smaller 
numbers Ps. ornatus and Ps. setarius (P. platurus). A good reason for this 
peculiar distribution is not easy to find, but the data known are scanty and 
insufficient and may partly rest on observations of local movements and if more 
facts were to hand , a different sketch of distribution of the species might 
perhaps be drawn up. 
The distribution of the genus Caeatua is likewise somewhat anomalous. The 
1) The species is included in the list of Togian birds collected by Meyer in 1871 ( 10 ), but this indi- 
cation is a mistake.
