Mr. Ridgway was perfectly justified when, in 1882, he differentiated this form (found 

 only in Kauai) from those of the neighbouring islands ; but, unfortunately, Mr. Sclater, 

 in his article on the genus in the 'Ibis' for 1885, suggested that it was the female of 

 G. sandvicensis, at the same time rightly determining the latter, of which he figured 

 the male and female. Dr. Stejneger, in 1887, separated the birds from Kauai as two 

 species, giving the name of C. dolei to that which he considered undescribed ; but 

 Mr. Perkins, to whom we owe the elucidation of so many knotty questions, has now 

 been able to ascertain that one form only inhabits the above-mentioned island. The 

 habits cannot be said to differ from those of the other members of the genus, the nest 

 and eggs resembling those of C. gayi. 



Description. — Adult male. Nearly uniform greyish above, with white rump and an 

 indistinct rufous nuchal collar. The wing and tail much as in C. sandvicensis. The 

 throat is orange-rufous, with no black markings, the colour gradually merging into the 

 white of the central abdomen. The chin is whitish, and there is very little rufous on 

 the forehead or above the eye. 



Adult female. The throat and forehead are much whiter. 



The young are very rufous above and chiefly orange-rufous below. 



Dimensions. — Total length 5*5 inches, wing 2 - 75, tail 2 - 78, tarsus 1, culmen -38.
