1869.] ON THE GENUS EUDTDAMIS. 69 



6. EuDTNAMis EANSOMi, Bp., Consp. i. p. 101,"Ceram," 2 vel cJ juv.'? (1850). (Plate X.mon^.)

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 are ever to be 

 found in E. honorata, E. malayana, or E. cyanocepliala. The bird here figured is either a young 

 male or an adult female procured by Mr. Wallace in the island of Ceram, specimens from which 

 are identical with those of Bouru. A second specimen has all the feathers of the chin and throat 

 turning to black, while the remainder of the lower surface is nearly immaculate rufous-buff. Ibis, 1869, 

 Another specimen has the throat perfectly black, as well as the head and nape. A fourth, from P' 

 Ceram, is entirely black except the abdomen, which is deep rufous-bay, — an adult male, having 

 almost completed its moult. A fifth, a male moulting into adult plumage, is pied jet-black 

 and rufous-buff. 



A peculiarity of the Ceram and Bouru birds in adolescent male and adult female plumage is 

 the regular well-defined and arched character of the rufous caudal bands and their great breadth. 

 Brisson notices this character in his description of C. imnctatus, L. ; and if not possessed by the 

 Amboyna bird, it will go far to support Dr. Cabanis's view. Brisson's words are " bandes 

 transversales rousses, formant chacune un arc de cercle." I have not observed this character iu 

 examples of Eudynamis from any other locality. 



7. Eudynamis eufivexter. Less., Voy. de la Coquille, p. 620, no. 23, " Nouvelle Guinea," 

 d adolesc. plum. mut. (1826). 



A single specimen of an adult male Eudynamis was obtained by Mr. Wallace at Dorey, in 

 New Guinea. Bill pale greenish. Its chief dimensions are : — wing 7*75 inches, tail 8, bill from 

 nostril -87. It differs from all the other species I am acquainted with, and I therefore 

 enumerate it as distinct. 



Lesson described from a young male passing into adult black plumage. It is probable 

 that Mr. Wallace's individual is referable to Lesson's species : at the same time the colour of the 

 bill does not quite agree; for the latter says "le bee est noir, la mandibule inferieure blanchatre." 



8. Eudynamis melanorhyncha, Miiller, I. c. sp. 2, " Celebes." 



This is the Eudynamis of Celebes, distinguishable from all others except E. facialis. Wall., 

 by its black bill at all ages. Having united under one species the Koels inhabiting the entire 

 region between Ceylon and China, the Himalayas, and South Australia, Professor Schlegel 

 remarks {I. c.) " C'cst un fait digne de remarque que cette espece, originaire de Celebes, se 

 trouve, pour ainsi dire, comme perdue au milieu de ces colonies nombreuses du Cuculus orioitalis, Ibis, 1809, 

 repandues depuis I'Hindoustan, jusqu'aux Philippines, a la Nouvelle Guinee et I'Australie." ^'' ""
