 Anthony coll. 



The amount of greenish gloss varies. Some examples, especially those 

 from the Fly River and Jobi, show a lot of bluish, almost purplish gloss, thus 

 approaching the Am form. The specimens collected by Anthony have very 

 huge bills. A better series from the Mountains of British New Guinea should 

 be compared to show if there is auy constant difference. 



Centropus menbeki aruensis Salvad.

<$ ad., Soengej Wanumbai, Kobroor Island, Am Islands, 3. ix. 1900. Hch. Kuhu 

 coll. (No. 443.) 



This specimen is very typical, showing a strong, almost purplish blue gloss 

 on the entire upper surface and tail. 



1 6 ad., Trangau, Aru Islands, 20. ix. 1900. Hch. Kuhu coll. (No. 2448.) 



This example is not so typical, showing very little of a blue sheen, thus being 

 similar to some specimens of C. in. menbeki. There is no other difference than 

 the blue gloss, and single specimens are sometimes not separable, therefore 

 ft menbeki menbeki and C. menbeki aruensis are only subspecies.

Centropus violaceus Qnoy & Gaimard, Voy. Astrolabe, Znol. i. p. 299 (1830— New Ireland). 



1 c? ad., New Ireland. Collected by a missionary. 



Differs from ft menbeki in the uniform purple or violet-bine colour, perfectly 

 black bill, but light (reddish) bare skin round eyes and yellow feet. Probably 

 subspecies of menbeki.

2 ? ¥, Korrido, 1879 (Misori). Ex Bruijn coll. 



Differs from C. menbeki and agrees with violaceus in having a quite black 

 bill. The bare facial skin and feet are dark, the gloss dark steel-bine. Probably 

 subspecies of menbeki and the rest. About the names Korrido (Kordo) and Misori 

 see Koe. Zool. 1901. p. 58.
