Eucaly2)ti, and other trees peculiar to the country they 

 inhabit ; but they diversify their food by occasionally devouring 

 large caterpillars. They can scarcely be considered gregarious, 

 but move about in small companies. Their flight is rather 

 powerful, but at the same time laboured and heavy j and 

 their voice is a low crying call, totally different from the 

 harsh screaming notes of the Cacatua. Each division of the 

 country, from the northern portions of the continent to 

 Tasmania, is inhabited by its own peculiar species. 



I have never seen a bird of this form from any other 

 country than Australia, but I have heard that an extraordinary 

 Parrot, said to be larger than any at present in our collections, 

 inhabits New Guinea, and which, from the description given 

 of it, will probably belong to this genus, or possibly to that 

 of Microglossum. The Calyptorhynchi lay from two to four 

 eggs in the holes of trees.

1 have abundant reasons for stating that every portion of 

 Australia yet visited by Europeans is inhabited by members 

 of the genus Calyptorhynchus, and that at least six species are 

 now known, each of which has its own peculiar limits, whence 

 it seldom or never passes. The present species is the one with
