774 HON. W. ROTHSCHILD ON THE CASSOW ABIES. [Juue 20, 



and 1899, I was much struck by the inadequate figures and de- 

 scriptions hitherto available, and I thought it might be useful if I 

 published a monograph of the genus Oasuarius, with coloured 

 figures and a detailed anatomical description. 



As my own journal was of too small a size to allow characteristic 

 plates to be given, I laid the matter before the Publication Com- 

 mittee and the monograph was accepted for publication in the 

 ' Transactions.' 



I now place before you the original drawings for this monograph 

 and a photograph of one of the birds. I find there are fewer 

 distinct species than has been hitherto supposed (11 are enumerated 

 by Count Salvador!) ; but, owing to their solitar}'^ habits and 

 restricted though wide distribution, most of the species have 

 developed into a number of local races or subspecies. 



Of distinct species I recognize 8, viz. : — 



1. Casuarius casuarius (Linn.), from Ceram, Aru, New Guinea, 



and Australia. 



2. Casuarius bicarunculatus, from Wammer and Kabroor Islands, 



Aru Islands. 



3. Casuarius uniappendiculatus, from Salwatti and Jobi Islands 



and the northern shores of Grerman and Dutch New 

 Guinea. 



4. Casuarius papuanus, from Salwatti and Dutch New Guinea. 



5. Casuarius picticollis, from German and British New Guinea 



(lowlands). 



6. Casuarius lorim, from British New Guinea (high mountains). 



7. Casuarius bennetti, from New Britain. 



8. Casuarius pTiilijpi, habitat uncertain. 



Taking cognizance of all the races, we find there are 18 recog- 

 nizable subspecies as follows : — 



1 . Casuarius casuarius. Ceram. 



(a) „ casuarius heccarii, Vokan, Aru Islands. 



(b) ,, casuarius salvadorii. Arfak. 



(c) „ casuarius sclateri. New Guinea, from Maclure 



Inlet to Samarai. 



(d) „ casuarius violicollis. Trangan Island, Aru Islands. 



(e) ,, casuarius australis. Queensland. 



(f) ,, casuarius intensus. Habitat uncertain. 



2. Casuarius bicarunculatus. Wammer and Kabroor, Aru 



Islands. 



3. Casuarius uniappendiculatus. Salwatti and Arfak. 



(a) „ uniappendicidatus occipitalis. Jobi Islands and 



Geelvink Bay. 



(b) „ uniappendiculatus auraniiacus. Huon Gulf, Ger- 



man New Guinea.
