Adult. Upper surface sootj^ black with a little greenish gloss, 

 somewhat purplish on the tail ; lower surface brownish grej', with 

 somewhat darker shaft-stripes ; feathers in front of the eye white, 

 broadly tipped with black ; under wing-coverts blackish. Total 

 length about 5 inches, bill at base 0-2, wing 5 "3 ; tail 2, nearly 

 quite even ; tarsus 0-4, thinly but obviously feathered if not abraded 

 by the string of the label. 



The plumage of the younrj bird does not differ from that of the 

 adult. 



This species is easily distinguished by its large size. The speci- 

 mens from Palawan seem to be a little smaller on the average. 



Hah. Palawan and Northern Borneo, where Everett found it 

 breeding in caves in October, making a nest of moss fastened to the 

 wall with its saliva. The island of Nias off the west coast of 

 Sumatra, and parts of Sumatra.

* I cannot adopt Q. E.. Gray's reasons for rejecting Thunberg's name and 

 calling this species C. nidifica ; and I agree with Salvadori and others 

 that the oldest and well-known name, i. e. fuciphaga of Thunberg, should 

 stand.
