has convinced me, as well, I believe, as every one who has paid them 
a visit, that they really belong to independent species. We are now 
therefore the fortunate possessors of no less than nine different species 
of this important group, of which, until lately, but four were known 
to exist in the whole world in a recent state. 
The newly arrived birds I allude to are examples of the Emeu 
of Western Australia (Dromeus irroratus, Bartlett), and the Casso- 
wary with the throat-wattles divided and far apart, which I have 
proposed to designate Casuarius bicarunculatus.

The Emeu of Western Australia may, as was pointed out by Mr. 
Bartlett, when he first described it at a meeting of this Society in 
May 1859*, be easily distinguished from the well-known Eastern 
bird by its spotted plumage. On comparing the feathers of the 
two species together, the mode in which this spotting is produced is 
clearly apparent. The feathers of D. irroratus are barred alternately 
with silky white and darkish grey throughout their length, terminating 
in a black tip margined posteriorly with rufous. Those of D. nove
