18/2.] MR. P. L. SCLATKR ON KAUP's CASSOWARY. 149 



berg's description ; and Rosenberg had expressly insisted on his spe- 

 cimen being adult, and showing no signs of a throat-wattle. I there- 

 fore sent a coloured drawing of our bird to Dr. Kaup, and requested 

 him to compare it with the original specimen of Casuarius kaupi in 

 the Darmstadt Museum. Dr. Kaup kindly replied to me that tbe 

 figure agrees well with the specimen, which, however, is by no means 

 perfect, the head and neck being original, and the body being made 

 up with the skin of the same bird, but the wings and legs being 

 wanting, and having been replaced from other sources. Dr. Kaup 

 added that his specimen was certainly not immature. Dr. Kaup also 

 forwarded me a plaster cast of the head of the same specimen, which 

 I now exhibit, and which, it will be observed, agrees in shape very 

 well with the head of our living bird, although in the latter, not being 

 so mature, the transvertical ridge is not quite so much developed. 

 Under these circumstances I came to the following conclusions : — 



1. That a second species of Casuarius occurs in New Guinea 

 more nearly allied to ft bennetti than to ft uniappendiculatus, the 

 only species previously known to inhabit that country. 



2. That this second species should bear the name C. kaupi, that 

 term having been erroneously considered synonymous with ft uni- 

 app endiculatvs. 



After having arrived thus far, I received the new part of ' Neder- 

 landsch Tijdschrift voor de Dierkunde,' containing the fifth and 

 concluding portion of Dr. Schlegel's "Observations Zoologiques." 

 Here I discovered that the existence of this second Cassowary in 

 New Guinea had been already noticed, H. v. Rosenberg having 

 transmitted two specimens of it (obtained on the western coast of the 

 Bay of Geelvink, nearly the same locality as that where the bird now 

 in our Gardens was captured) to the Leyden Museum. Dr. Schlegel 

 has referred these specimens to the Mooruk {Casuarius bennetti), 

 observing, at the same time, that H. v. Rosenberg had considered 

 them distinct, and had given them the name Casuarius papuensis. 



Having at the present moment specimens of the true Casuarius 

 bennetti and of the allied bird from New Guinea living side by side 

 in the Gardens, we can have no difficulty in deciding that they 

 belong to quite different species. Indeed Dr. Schlegel could hardly 

 have fallen into the error of uniting them if he had had a specimen 

 of C. bennetti for comparison. In C. bennetti the naked space on 

 the throat is less extended, and the whole of the naked skin is of a 

 uniform cobalt-blue all around. In C. kaupi the back of the neck 

 is of a bright red, as are likewise the two lateral neck-stripes, and 

 the sides and back of the head are of a bright iridescent silvery 

 green. Nevertheless there can be no question that the two species 

 are closely allied, being of nearly the same size, and having the 

 casque of the same form. 



In my opinion, therefore, the synonyms of the new Papuan Cas- 

 sowary should stand as follows : —
