Australian Birds in the Collection of the Linnean Society. 239 



species exhibit a resemblance to the birds of the genus Procnias, 

 111., while by the puftecl-out appearance of the feathers about 

 the head, we trace also an approximation to some of the Lin- 

 nean Pari. An approach in character may also be noticed 

 between them and the Muscicapœ ; among which, indeed, the 

 typical species of the present group has been hitherto placed. 

 The situations which we at present assign the group, in con- 

 sonance with the views exhibited on the subject in a preceding 

 volume of these Transactions*, will be found to embrace all 

 these affinities, and to unite all the birds thus approaching each 

 other in one conterminous assemblage.

" This species," Mr. Caley says, " is called Thunder-bird by 

 the colonists. I have not often met with it, at least in perfect 

 plumage. It frequents the gree7i wattle-trees in Paramatta. The 

 natives tell me, that, when it begins to thunder, this bird is very 

 noisy."
