Hob. Bonin Islands — Parry group, Bailey Islands, and Sulphur 

 Islands. 



besides one of the types of the species, kindly sent for my 

 inspection to the British Museum by the authorities of the Sencken- 

 perg Museum, I have seen a series of nine specimens belonging to 

 Mr. Seebohm, and collected by Mr. Hoist in the Parry group, 

 Bailey Islands, and Sulphur Islands. They belong to both sexes, 

 and some are very young. The latter are slate-black, with a rufous- 

 brown tinge at the tips of the feathers of the head, and with a purple 

 tinge on the edges of the feathers of the mantle ; the interscapular 

 feathers haw a slight bronze-purple gloss. The young bird is quite 

 different from the young of C. janthina from Japan, which is not 

 slate- black but brown.
