p. 596) Count Salvador! includes under tlie heading 

 C. beccarii birds from Woknn, Aru Islands, and from the 

 mainland of New Guinea, while the description is made from 

 D'Albertis's notes on specimens from the Fly River. This 

 is not in accordance with f acts, for while the true C. c. beccarii 

 occurs only on V/okan, the bird from Southern Dutch and 

 British New Guinea is a very different and much larger 

 form which must bear the name of C c. sclateri, Salvad. 

 There is also an error in the description of the lower 

 sides of the neck, as they are not flesh-colour in the adult 

 C. c. sclateri, but scarlet and blue as in the other forms of 

 C. casuarius. Other authors, as well as Count Salvador!, 

 have included Arfak and the northern parts of Dutch New 

 Guinea in the range of C. c. beccarii, so that all the three 

 New Guinea forms — C. c. beccarii, C. c. altijugus, and C. c. 

 sclateri — have been confounded under that name : Dr. Sclater 

 and Count Salvador! afterwards uniting C. c. altijugus with 

 C. b. salvadurii. In the same volume Count Salvador! 

 describes the bird I afterwards called C. lorice, but states that 

 it is the fully adult C. picticollis. The former species 

 (C lorice) has no connection with either C. picticollis or 

 C. papuanus, but constitutes together with C. roseigularis 

 and C. keysseri a small separate group in which the front of 

 the neck is red or pink, while in C. picticollis and C. papuanus 

 the fore-neck is blue, as in C bennetti. 



Dr. Sclater in 1878 described Casuarius altijugus from a 

 skin obtained at Wandammen (Dutch New Guinea), but 

 afterwards considered it to be the same as C. salvadorii, 

 Oustalet, described six weeks earlier ; this, however, is not 

 the case. When I described my C. intensus, Dr. Matschie 

 suggested that I had redescribed C. altijugus, Sclat. ; this, 

 however, is also incorrect. The fact is that C. salvadorii and 

 C. altijugus are the representatives respectively in Arfak and 

 on the North Coast of Western New Guinea of C. bicaruncu- 

 latus and C. casuarius, just as my C. intensus and C. sclateri, 

 Salvad., are in South and Central Dutch New Guinea. 



Recently Dr. Van Oort has redescribed C. altijugus under 

 the name of C. bistriatus.
