134 HON. W. ROTHSCHILD ON THE GENUS CASUARIUS. 
is bright red. The casque is about equally developed at this age in the two species. 
The legs of the new species are smaller, from which I doubt if it attains to quite so 
large a size as the other.” 
The next we hear concerning this species is the arrival of an immature bird in the 
Zoological Garden of Amsterdam ; this grew up, and thus was afterwards the first adult 
described and figured by Schlegel. Also in this case Rosenberg was the first to 
discover the actual home, for he obtained it on the island of Salwatti, and afterwards 
specimens became known from several places on the opposite coast. 
The bird in Amsterdam laid a pale green egg, ‘thickly covered with raised spots of 
dark green, and measuring 136: 89 mm.” 
I have an egg in my collection (from the Buckley collection, bought from T. Cooke, 
1871, who had it in exchange from ‘Mr. Franks”: this means probably that it was 
from the Amsterdam dealer Frank, who had it from the Zoological Gardens, for it has 
on its label “ Maart 1865” (or 6, the 5 being obliterated), this being about the time 
when the bird laid eggs there). This egg differs from other Cassowary-eggs in having 
numerous single glazed round knobs, like pin-heads, few of them being connected 
with each other. The descriptions of the two eggs of C. unappendiculatus by Schalow 
(Z. c.), both from different sources, agree with mine—the peculiar isolated pin-head-like 
elevations being well described and discussed as distinguishing the wnappendiculatus- 
egg from all others. One of those in the British Museum, about the origin of which 
there is no doubt, as it is one of the eggs laid in Amsterdam, agrees also with these in 
having the separate knobs, while two others, from Frank, and one said to have come 
from Salwatti, are more like those of Casuarius casuwarius. ‘The one with the isolated 
knobs measures 137: 88 mm., my own 151: 81, Schalow’s 146: 96, 148-5: 49°5 mm., 
while Sclater gives only 136: 89. Sclater also speaks of raised “spots” only. On the 
other hand, seven eggs in the Leyden Museum, sent by Bernstein and Rosenberg, and 
said to be from Sorong and Salwatti, do not show these characteristic isolated pin-head- 
like elevations, but rather a more connected network of glazed granulations. They 
measure 145: 90, 145: 91, 145: 90, 143:91, 147: 92, 142:95,145:96 mm. They 
are all very large. 
It must therefore be left to future research whether the peculiarly isolated knobs on 
some well-authenticated eggs of C. unappendiculatus are a specific character; but at 
present this view cannot be taken, unless the identity of all the eggs in the Leyden 
Museum and of some of those in the British Museum is doubted. 
As usual, we know nothing definite respecting the biology of this bird in a wild state. 
Rosenberg tells us that an immature bird he got in Ternate was running about freely 
and was much attached to people, while it was a fierce enemy to cats and dogs. When 
it got angry it put up its feathers and emitted a peculiar blowing cry, followed by a 
grunting like that of a young pig.
