HON, W. ROTHSCHILD ON THE GENUS CASUARIUS. 121 



and to this day we know nothing absolutely certain as to the colour of the naked parts 

 of wild-shot Arfak birds ; but there are a certain number of birds sent alive to Europe 

 as coming from New Guinea, and which agree neither with Casuarius casuarius from 

 Ceram, nor with C. c. beccarii from Aru, nor G. c. sclateri from Southern New Guinea 

 in colour, and these birds 1, for the present, take to be Casuarius casuarius salvaclorii 

 as they agree in other respects. 



The bird from which I made the above given description lived two years at Tring 

 and one year in the Society's Gardens. It is fully adult, and a male. I have had 

 several younger ones, but none lived to maturity. 



The bird shortly mentioned by Beccari in his ornithological letter (Ann. Mus. 

 Genova, vii.) as agreeing in the form of the helmet with C. casuarius, but having 

 three wattles, namely, two lateral ones, and below these a smaller median third one, 

 was a young bird bought at Warbusi, a little to the south of Dorei. It was left at 

 Ternate to grow up, where Laglaize saw it still alive in July 1877, but it was 

 eventually lost. It must, in my opinion, have been an aberration of C. c. salvaclorii. 

 Oustalet says that the type of C. salvaclorii came also from Warbusi, at the bottom of 

 Geelvink Bay. Warbusi, however, is near Dorei, while Wandammen is the place 

 at the southern end of the Bay whence the other specimens from Laglaize were said to 

 come. Therefore Salvadori (1881) thinks that Warbusi might be a mistake for 

 Wandammen ; but I see no reason why it should not be correct, since C. tricaruncu- 

 latus is not a species according to my judgment, as I have a similar aberration of 

 C. c. sclateri. Laglaize probably bought his specimens from Bruijn or his hunters. 



When excited these birds extend the neck horizontally and emit five or six very 

 loud grunting and grating sounds ; frequently, when very angry, they spit several times, 

 elevate their wing-rudiments and the feathers of the hind-quarters, and peck and kick 

 most viciously.
