Remarks. This little Rail in general appearance resembles 

 Ealius Itivijii from Aastralia^ but on comparison presents so 

 many impjortant differences tiiat it might almost be separated 

 generically. The chief distinguishing feature of the new 

 species is the enormous development of the feathers on the 

 back and rump, which have become a huge bunch like that 

 of the Puff- birds [Bucco] of South America. 



The single specimen was sent for description by Count von 

 Berlepschj who considered it to belong to a new species. It 

 is the property of the Stuttgart Museum. It is named in 

 honour of the famous botanist, Baron von !M tiller, of Mel- 

 bourne, wlio presented the specimen. 



The Hon. Walter Rothschild exhibited three new birds 

 which he had lately received from his collector in the Sand- 

 wich Islands, and characterized them as follows : —
