of the Genus Eudynamis. 343 



examples from the two localities do not strikingly differ: — 

 Ceram, wing 7 inches 10 lines to 8 inches 4 lines ; Amboyna, 

 wing 8 inches 1 line. 



It may be that the Amboyna Koel and the one known to in- 

 habit a part of New Guinea are identical ; but I am induced to 

 decide that the Amboyna and Ceram Koel differ, solely because 

 Forsten considered them to be different. He is the only orni- 

 thologist, besides Professor Schlegel, who,'we know for certain, 

 actually compared specimens from both islands ; and, what is 

 more, he procured the specimens himself. 



Our only knowledge of the comparative size of the two species 

 is confined to the dimensions given by Professor Schlegel already 

 quoted : it is not sufficient to warrant us in affirming that the 

 Ceram bird is the largest ; and for the time the question must 

 be left undetermined. Moreover, as the Dutch naturalists all 

 unite in giving Cuculus punctatus, L., from Amboyna, the pro- 

 bability is that Count Bentinck's specimen came from there ; 

 I therefore cannot follow Dr. Cabanis so far as to refer the Ceram 

 and not the Amboyna bird to C. orientalis vel punctatus, L.

This is a very handsome species, and perhaps the largest of 



the genus.

The bill is not so long nor as stout as in my Javan specimens 

 {E. malayana), the other dimensions being greater. The adult 

 male is entirely black with a green gloss; but the garb of the young 

 birds assumes the most striking and peculiar variations, none of 

 which ai*e ever to be found in E. honorata, E. malayana, or E. cya- 

 nocephala. The bird here figured is either a young male or an 

 adult female procured by Mr. Wallace in the Island of Ceram, spe- 

 cimens from which are identical with those of Bouru. A second 

 specimen has all the feathers of the chin and throat turning to
