varies also somewhat. Our males from Rook Island have the wings 242 — 245, 

 once about 248 (the latter rather worn, measurement therefore only approximate) 

 mm., while the females have wings of 232 to about 240 (the Latter worn) mm.

 While the adult female has the crown blnish grey, that of the young female is 

 of a brownish green.

Comparing this fine series with seven skins from New Britain, it appears that 

 the bills are mostly, but not constantly, rather higher in the Rook Island specimens. 

 The extent of black on the forehead is, as we know, very variable, but in the Rook 

 examples the black covers the whole, or nearly the whole, of the crown, and in one 

 it extends in a line right along the hindneck to the back. In the New Britain skins 

 the extent of black on the head is generally less, and two are albinistic : one entirely 

 white with one black quill in the right wing, the other white with a greyish tinge, 

 grey upper wing-coverts, dull black forehead, and one black-and-white feather 

 among the scapulars. The nestling is dull black, head and neck with pale rufous 

 shaft-stripes, throat and chest with similar round spots at tip of feathers. Abdomen 

 uniform dull black — not with brown bars as in a specimen described by Reicheiiow. 



If a better series from New Britain were to hand it might become necessary to 

 separate the form from Rook Island.

 This appears to be a perfectly adult female. It is very much larger tlian the 

 New Guinea form (E. o. rufioeiiter), wing 205 mm. The spotting of the upperside 

 is about the same as in the latter, bnt the spots on the lesser upper wing-coverts are 

 whitish. The underside is buffy white with narrow black crossbars.

Unfortunately we received only one adult (or nearly adult) male. This has a 



larger bill and wing than the New Guinea specimens (wing 131 -3 mm.), thus agreeing 



with our recently described C. a. fortior.
