Advlf. Plumage black ; casque very high, broad and massive, dark brown ; bill long 

 and not pointed. Head and occiput pale greenish blue. Upper part of hind-neck 

 deeper blue, followed by a space of mixed blue and red, ])roducing a somewhat livid 

 pule purple eflect. Lower part of hind-neck scarlet. Chin, throat, and fore-neck 

 dark blue. Wattles large, broad, and very conspicuously joined at base, of a deep 

 fleshy-red colour, wliich colour runs up in a narrow line nearly to below the ear. 

 Naked lower sides of neck mixed red and blue. A very large bird, but 1 have not 

 been able to measure a fully adult dead example. 



Young (three-fourths grown). Fore-neck indigo-blue, head and occiput pale blue ; 

 hind-neck orange-yellow, with a purple patch between blue and orange. Naked lower 

 sides of neck, anterior half dull blue, posterior lialf orange-yellow. Plumage brovpn.

Hab. Vokan, Aru Islands. 



Dr. Sclater (P. Z. S. 1875, p. 87) first recognized the Aru Cassowary as a distinct 

 species, and gave a woodcut, showing a side view of the head and the wattles from in 

 iiont, accompanied by the iollowing diagnosis : — 



" Casuarius similis C. australi ct crista iiari modo elevata : sed caruncula ceroids ana 

 media, ad apicem divisa.

 " Mus. civit. Genoeusis." 



In the same volume our author also mentions a Cassowary from the south 

 coast of New Guinea, of which he believes that it " probably is of the same species 

 as that of the Aroo Islands," namely C. beccarii. This specimen was afterwards 

 described as C. sclateri, but later on reunited with C. beccarii, and so it has remained 

 also in the 'Catalogue of Birds.' However, I am fully convinced that the form from 

 Southern New Guinea can be separated from that from the Aru Islands, where it 

 inhabits, so far as v^e know, only the northern island of the Vokan group. 



I am not able to give descriptions of well authenticated eggs of Beccari's Cassowary, 

 but there is an enormous egg in the British Museum from the Aru Islands, which is 

 named C. bicaruncidatus, which, however, from its large size I am more inclined to 

 believe is that of either C. c. beccarii or C. c. riolicoJUs. It measures 140 : 2'6 mm. 

 Its granulations are low.
