Adult male. General colour above dark silvery grey, all the 

 feathers ashy blackish at base ; a white shoulder-patch on the upper 

 part of the scapulars ; wings and tail entirely black ; head bare, 

 excepting the lores and base of the forehead, which are black, this 

 extending in a narrow line down the centre of the head, and joining 

 a narrow black collar on the nape which extends round to the ear- 

 coverts and cheeks, which with the under surface of the body are 

 entirely black ; sides of body and flanks silvery grey ; thighs black ; 

 under tail-coverts black, washed with dark silvery grey ; under 

 wing-coverts and axillaries black : quills brownish black below : 

 " bill and legs black ; bare skin of face white, tinged with pink ; 

 iris bright brown " (A. Everett). Total length 10'5 inches, culmen 

 1-2, wing 5, tail 4-3, tarsus 1-3. 



Adult female. Similar to the male : " bill and feet black ; iris 

 brown" {L. C. Layard). Total length 10-5 inches, culmen 1-2, 

 wing 5"2, tail 4"65, tarsus 1-25. 



Sarco^is loivi was described by me from the island of Si Butu in 

 the Sulu Archipelago, but the differences on which I depended for 

 its specific separation do not hold grod. Both males and females 

 are in the collection with the back entirely grey, and with the 

 breast entirely black. From the remains of grej^ both above and 

 below overspreading the black plumage, it would appear that the 

 pure silvery-grey colour is a seasonal plumage. Specimens from 

 Leyte, Basilan, and Mindanao are rather small (wing 5 inches), 

 while the Sulu birds are large (wing 5'25).
