Birds of Celebes: Psittacidae. 
East Celebes (Nat. Coll.); Peling and Banggai (Nat. Coll.); Sula Islands - Snla Besi 
and Sula Mangoli (Allen f 1, d 17, Bernst. g 5, Hoedt g 5). 
Observation. We are unable to find that tbis subspecies differs in North and South Celebes 
and Baton, and the Islands Banka, Manado tua and Mantehage off the Minahassa, 
the size is equal in all parts of the island; there is considerable difference in coloration 
between the old male and the female or young male, and old male specimens vary 
amongst themselves in the same locahty (Manado), having the blue tint of the rump 
lighter or darker, etc.

the average size in Celebes.

“Areaa” or “Area uwawi”, Talaut, Nat. Coll. 
Diagnosis. Intermediate between the Celebes and Sangi forms. 
Measurements. Wing (19 examples) 210—227 mm; tail c. 140 mm; culmen from cere 
c. 32 mm. 
Distribution. Talaut Islands: Kabruang and Karkellang (Nat. Coll.). 
Observation. There is, as a rule, more blue on the wing-coverts about the bend of the wing 
in Talaut and Sangi birds than in those of Celebes, but this character varies much 
in different individuals and with age. 
It is curious that no form of T. muelleri has been found on Siao or the other 
islands between Celebes and Sangi. It can hardly be that the islands are too small 
to support two forms of Tanygnathus, T. megalorhynchus being there already, for 
Kabruang and Karkellang in the Talaut group are inhabited by three species of this 
genus, and the former island seems to be but little larger than Siao. 
Muller’s Green Parrot has two very close allies in T. everetti^ Tweedd. 
of Samar, Panay and Mindanao, and T. hurhidgei Sharpe of the Sooloo Islands.
