HON. W. ROTHSCHILD ON THE GENUS CASUARIUS. 12] 
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. ¢. beccarti from Aru, nor C. ¢. sclateri from Southern New Guinea 
in colour, and these birds I, for the present, take to be Caswarius casuarius salvadorii 
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.jc. salvadorii. 
Oustalet says that the type of C. salvadorit 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- 
Jatus 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.
