774 HON. W. BOTHSCHILD ON THE CAS80WAEIES. [June 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 

 ])ublished a monograph of the genus Casuarkis, 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 publicatiou 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 hitlierto supposed (11 are enumerated 

 by Count Salvadori) ; but, owing to their solitary 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. Casiiarms casuarius (Linn.), from Ceram, Aru, New Guinea, 



and Australia. 



2. Casuarius hicat-unculatus, from Wammer and Kabroor Islands, 



Aru Islands. 



3. Casuarius uniappendicidatus, from Salwatti and Jobi Islands 



and the northern shores of German and Dutch New 

 Guinea. 



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



5. Casuarius picticoUis, from German and British New Guinea 



(lowlands). 



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



7. Casuarius bennetti, from New Britain. 



8. Casuarius philipi, habitat uncertain. 



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

 nizable subspecies as follows : — 



1 . Casuarius casuarius. Ceram. 



(a) „ casuarius beccani. Vokau, 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 uniappendicidatus. Salwatti and Arfak. 



(a) „ uniappendiculaius occipitalis. Jobi Islands and 



Geelvink Bay. 



(b) „ uniappendiculaius aurantiacus. Huon Gulf, Ger- 



man New Guinea.
