Mr. P. L. Sclater on two new Struthious Birds. 213 



of Western Australia (Dromceus 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 B. Novce 

 HoUandice 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 as in D. Novce HoUandice.
