Birds of Celebes; Psittacidae. 
5. Talaut Islands. 
Adult males from this group hare the patch on the occiput and carpal bend 
light bright blue (Cambridge or flax-flower blue — Eidgway IX, 14), purer even 
than in the Pehng form, and this tint is a good deal more extended on the lesser 
wing -coverts near the carpus; cervical collar above the mantle deep orange; size 
rather large: wing in 14 examples of different sex and ages 177 — 194 mm. 
6. Sangi. 
The locality is recorded by Briiggemann (5) alone; he describes the collar 
as purer green, with the yellow part over the mantle brighter tha.n in birds from 
Celebes, the size large: wing ca. 190 mm. 
7. Siao. 
Schlegel (f 2) considered the collar above the mantle to be brighter and the 
spot on the crown broader i) than in Celebesian males. There are two males in the 
Leyden Museum from Siao, examined by one of us; of these one certainly has a 
lighter and brighter collar than males from Celebes, the other — perhaps not fully 
coloured — is Hke the latter. Three young specimens from Siao in the Dresden 
Museum measure: wing 172 — 187 mm.

Distribution. Celebes and the neighbouring islands: Minahassa (Wallace 2, e 5, 15, Meyer 7, 
etc.); Gorontalo District (Eosenb. f 2, v. Duivenb. f 2, Meyer 7); Togian Is. 
(Meyer 7), Lembeh Islands (Xat. Coll.); Kandari, S. E. Celebes (Beccari4); Buton 
S. Mull, b 2, fiy, S. Peninsula (Wallace 2, e 3, 15, Platen 12, etc.). — Siao, 
Sangi Is. (v. Duivenb. f 2, Nat. Coll.); (?) Sangi Islands (Fischer 5, 14)-, Talaut 
— Karkellang Id. (Nat. Coll.); (?) Buru (Hoedt (2)-, Peling and Banggai Is 
(Nat. Coll.). 
Schlegel records a young female of this species killed by Hoedt in the Bay 
of Bara on the North-east coast of Buru; we are unable to form an opinion as to 
tliis occurrence. 
The Eacket-tailed Parrots of the genus Prioniturus range from the Philip- 
pines, including Palawan and Sooloo to Celebes and possibly Buru. Nine 
distinct forms have been described, two or three of them being local races and 
only worthy of subspecific distinction. P. platunis may fairly be regarded as 
the most highly differentiated of the group. The adult male excels its com- 
patriot in Celebes, P. jlavicans, by having two patches of colour, a red and a 
lilac one on its green head, whereas the male P. Jlavicans has a blue head 
1) Varies with age, and the shape thereof depends much upon the manner of preparation of the skin.
