Australian Birds in the Collection of the Linnean Society. 239 
species exhibit a resemblance to the birds of the genus Procnias, 
lll, while by the puffed-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 Muscicape ; 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.

noisy."
