Casuarius keysseri, sp. n. 



Adult. Casque as in C. picticoUis, Sclat, Head and neck 

 blue ; occipital region at the base of the casque, lores, and the 

 area behind the eyes black; sides of the lower part of the 

 neck brilliant deep crimson edged with blue ; front of the 

 neck and throat almost completely covered by a large fan- 

 shaped patch of pale rosy-red. 



This bird will, I think, prove to be the northern repre- 

 sentative of C. loricE, Rothsch., just as C. p. hecki, Rothsch., 

 is of C. piciicollis ; the drawing and description of the naked 

 parts are, however, so different, that until I receive living 

 examples of both forms for comparison, I prefer to treat it 

 as a species.

The discovery made by Mr. Goodfellow that two distinct 

 forms of two-wattled Cassowary occur together on the 

 JMimika River has so completely upset my classification 

 that I have carefully reviewed the genus Casuarius, and 

 find that the ten forms, possessing two wattles placed side 

 by side, fall naturally into two groups — one consisting of 

 Casuarius casuarius divided into six subspecies or races, 

 the other of C. hicarunculatus divided into four. 



When I described C c. violicoUis I did so from a fully 

 adult living specimen, purchased from a sailor, who stated 

 that he had brought it from the Aru Islands. At the time 

 I expressed my conviction that, if the bird really was a 

 native of the Aru Islands, it could only have come from the 

 Island of Trangan, as Wokan, Wammer, and Kobroor were 

 inhabited by other forms of Cassowary, and the remaining 

 islands were too small to provide a home for so large a bird. 

 Some years later Trangan was visited by the late lieinrich 

 Kiihn for the purpose of collecting birds and insects for the 

 Tring Museum. Among the birds sent home was the skin 

 of a Cassowary, shot by himself, and accompanied by a very 

 accurate coloured sketch. This proved tliat my original 

 surmise was correct, and that C. c. violicoUis does inhabit 

 the island of Trangan. In the ' Catalogue of Birds ' (xxvii.
