 Platycercus koroensis, Layard, Ibis, 1876, pp. 143, 391, 394. 



Adult male (type). Similar to P. tabuensis, but it has a narrow 

 blue collar, scarcely observable without particular attention ; rump- 

 feathers edged and tipped with dark cherry-red, of the same shade 

 as the inferior parts of the body : " irides red ; bill and feet black " 

 (Layard). Total length 17-5 inches, wing 9-5, tail 8'3, bill 1-38, 

 tarsus - 98. 



Adidt female (type). Similar to the male, only smaller. Total 

 length 10-5 inches, wing 8-5, tail 7 - 5, bill 142, tarsus 91. 



Bab. Koro, Fiji Islands. 



I have only seen the two typical specimens of Platycercus 

 koroensis, Layard, one of which is now in the British Museum. Both 

 have the rump-feathers edged with dark cherry-red, and it is quite 

 possible that this character, which is accidental in the other allied 

 species, may be constant in the Koro birds. 



It seems to me very doubtful whether Psittacus hysginus, Forst., 

 is this species, especially as it was described from Eaoowe (Tonga 

 Islands). Conurus anna, Bourj., the type of which is in the Phila- 

 delphia Museum, has been identified by Cassin, and seems to be the 

 same as P. koroensis, although the dimensions do not agree; for this 

 reason I have preferred using Layard's name till a further exa- 

 mination of Bourjot's type can be made.
