Birds of Celebes: Psittacidae. 
East Celebes (bTat. Coll.); Peling and Banggai (Nat. Coll.); Sula Islands — Sida Besi 
and Sula Mangoli (Allen f 1, d 17, Bernst. g 5, Hoedt g 5). 
Observation. We are unable to find that tliis subspecies difiers in North and South Celebes 
and Buton, and the Islands Banka, Manado tua and Mautehage off the Minabassa, 
the size is equal in aU 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 locality (Manado), having the blue tint of the rump 
lighter or darker, etc.

“Areaa” or “Area uwawi”, Talaut, Nat. Coll. 
Diagnosis. Intermediate beLveen 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 ciu'ious 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. megalorhynclms being there already, for 
Kabi’uang and Karkellang in the Talaut group are inhabited by three species of this 
genus, and tlie 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. burhidgei Sharpe of the Sooloo Islands.
