A good part of the above synonj^my has been taken from Count Salvadori's paper on tlie 'Chal- 

 lenger' collections in the Proccedings of the Zoological Society for the present year, and it gives some re- 

 ferences which had escaped my notice in 1874. 



It would seem that Professor Schlegel was not far wrong when he hinted that the bird figured by 

 Mr. Sclater in the 'Ibis' was not the young of A. poliocephalus, but of the bird he called A. rufitorques; 

 for I exaniined the specimen in Company with Count Salvadori and I agree with him that it is a young 

 bird otAstor etorques. All rcferences to this young specimen, therefore, in the writings of Sclater, Wallace, 

 and myself should be referred to A. etorques. 



Dr. Meyer coUected two specimens in the striped plumage described by Salvadori as U. spHothorax, 

 a species which he has now abandoned, as it seems to be a sort of second plumage which the bird as- 

 sumes betöre finally getting the adult garb, and the stripes on the breast disappear gradually. 



The foUowing are the measurements of the speciemens now before me compared with those in the 

 British Museum: —
