Mr. P. Li. Sclater on two new Struthious Birds. 213 
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 
Hollandie are uniform blackish grey from the base to the extre- 
mity, which is black with a broad subterminal band of rufous. 
On comparing the two living birds together, we find D. irroratus 
generally of a much more slender habit. The tarsi are longer 
and thinner, and the toes longer and much more slender. The 
tarsal scutes are smaller. The irides are of a pale hazel, instead of 
a reddish brown asin D. Nove Hollandie.
