360 DR. SCLATER ON THE STRUTHIOUS BIRDS 



5. CaSUARIUS AUSTRALIS. 



Casuarius australis, Wall, Illustrated Sydney Herald, June 2nd, 1861; Gould, P. Z. S. 

 1857, p. 270. 

 This Cassowary is only known from tiie account of it furnished to the newspaper 

 above-named by Mr. William Sheridan Wall, late Curator of the Australian Museum 

 at Sydney, and reprinted by Mr. Gould in the Society's ' Proceedings.' It is said to be 

 distinguished by a " bright-red helmet and blue and scarlet caruncles." There is no 

 example of this bird in any museum, the original skin obtained by Mr. Wall having 

 been unfortunately lost'. 



IV. Drom^us. 



1. DrOM/EUS NOV^-HOLLANDIiE. (PI. LXXV.) 



This well-known bird appears to inhabit the interior of New South Wales and the 

 whole eastern portion of the Australian continent. The figure is taken from a bird 

 presented to the Society's Menagerie by the Marchioness of Londonderry in 1S57. 



2. DromjEUS irroratus. (PI. LXXVI.) 



Dromceus irroratus, Bartlett, P. Z. S. 1859, p. 205 ; Sclater, P. Z. S. I860, p. 248. 



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. nova hollandite are uniform blackish grey from the base to the extremity, 

 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. nova 

 hollandia. 



The example of D. irroratus in the Gardens of the Zoological Society of Amsterdam 

 was brought by a Dutch vessel from Albany, King George's Sound. I have reason to 



' A sixth species of Cassowary has been described since the paper was read, under the name Casuarius kaiipi, 

 by Herr G. von Rosenberg, of Amboyna, in Cabanis's Journal fiir Ornithologie (1861, p. 44). It is from New 

 Guinea and the island of Salawatty, and has no caruncles on the neck. The species will therefore now stand as 

 follows : — 



1. C. gateatus, ex Ceram. 4. C. kawpi, ex Not. Guinea et Salawatty. 



2. C. bicarunculatus, ex loc. ignot. 5. C. bennetfii, ex Nov. Britannia. 



3. C. wiiappendiculatus, ex loc. ignot. 6. C. auatralis, ex Nov. Holland. Bor.
