This species, confined to the island of Oahu, had long been confounded with C. sand- 

 vicensis of Hawaii, until my paper in the ' Proceedings of the Zoological Society ' for 

 1891 appeared; but the whole matter may now be considered finally settled, owing 

 to the exertions of Mr. R. C. L. Perkins, who obtained both young and old of all the 

 three members of the genus, and proved conclusively that the former had the rump 

 tawny and the latter white. 



The habits of this bird are apparently identical with those of the forms from the 

 other islands. The nest, according to Mr. Rothschild, is placed in a fork about ten to 

 thirty feet high, and .is composed of fine roots and moss, with a lining of the former and 

 herbage, being decorated externally with lichens. The eggs are white, with small spots 

 and blotches of brick -red. 



Description. — Adult male. Above much as in C. sandvicensis, but the spots on the 

 wing-coverts have the appearance of bars. The throat is more conspicuously marked 

 with white, and the breast is almost entirely white. 



Adult female and young differ from the male as do those of C. sclateri. 



Dimensions. — Total length 5*4 inches, wing 275, tail 2-76, tarsus 1, culmen -4. 



1 These references must be regarded with doubt, though Bloxam's specimens were most likely obtained in 

 Oahu. Two of them were in the British Museum so lately as 1868, as stated by Mr. G. B. Gray in a letter 

 written by him in that year, and shown to me by Prof. Newton. They are not, however, included by 

 Dr. Sharpe in his ' Catalogue ' (iv. p. 232) as existing in 1879, any more than is a specimen of the " Muscicapa 

 rnaculata" of Gmelin, which Mr. Gray in the same letter mentions as being in the Museum, and then thought 

 to be the young of C. sandvicensis.
