to the common species {Tropidorhi/nchus cornicidatus), from 

 which it may also be readily distinguished by the crown of 

 the head being clothed with well-defined, small, lanceolate 

 feathers. Of its habits and economy nothing is known ; but 

 as it is very nearly allied to the last-mentioned species, we 

 may reasonably conclude that they are very similar. 



Crown of the head silvery grey ; the remainder of the head 

 naked, and of a blackish brown ; throat and all the under 

 surface white; back, wings, and tail brown; bill and feet 

 blackish brown. 



Total length 10^ inches ; bill If ; wing 5|; tail 4^; tarsi 1|^.

This is strictly a bird of the interior of the south-eastern 

 portion of Australia, and is never, so far as I am aware, found 

 on the sea-side of the mountain ranges. I observed it in 

 tolerable abundance during my tour to the Namoi ; first 

 meeting with it in the neighbourhood of Brezi, whence as I 

 descended the river to the northward it gradually became 

 more numerous. I killed both adult and young birds in De- 

 cember, the latter of which had just left the nest, consequently 

 the breeding-season must have been about a month previous. 

 The yellow colouring of the throat peculiar to the period of 

 immaturity is entirely wanting in the adult, and the bird is 

 one of the plainest -coloured species of the Australian Pauna. 



Its habits and manners are very similar to those of the 

 Tropidorhynclms cornicidatus ; like that bird it feeds on insects, 

 berries, fruits, .and the flowers of the Eucalypti, among the
