 recurved feathers of the crest." (Rothsch. & Hartert, I.e.)

Dr. Hartert has strongly advocated the separation of C. 

 triton into three subspecies : a larger one from the mainland 

 of New Guinea, an intermediate one (C. trobriandi) from the 

 Eastern Papuan Islands, and a smaller one (C. macrolopha) 

 from the Western Papuan Islands and the Aru Islands. 

 In the ' Catalogue of Birds ' I have already mentioned these 

 races, but I am still of opinion that they cannot be accepted 

 as specifically or even subspecifically distinct. On the main- 

 land of New Guinea there are large and small birds, of the 

 latter description are those from Sorong and Ramoi on the 

 western coast of New Guinea and also those from the Katau 

 River on the southern coast, while some from Mysore in 

 Geelvink Bay are exceptionally large (I have measured the 

 wing of one reaching 3;")5 millimetres) and others from 

 the same island arc of the ordinary size.
