BLACK-WINGED BABBLEK. 
Crater opus atripennis , Swains. 
Rufous ; wings and tail black ; head and neck hooded with 
greyish white, bordered by black ; tail short. 
Only one specimen of this new and remarkable bird 
has yet come under our inspection, and we therefore 
conclude it is particularly rare. Its form also, no 
less than its colours, has some peculiarities. In its 
general structure it closely resembles the two pre- 
ceding species ; that is, in the shape of the hill, 
wings, feet, and tail, but the latter member, com- 
paratively, is very short, for it does not extend 
beyond the -wings more than one inch and a half. 
Hence, at first sight, it seems so closely allied to 
Timalia thoracka* , Swains., as even to enter into 
that genus. The great distinction, however, of 
Timalia, is its remarkably short and rounded wings ; 
so short, indeed, that they barely reach to the base 
of the tail. In the bird before us, this character 
does not exist ; the wings, although much rounded, 
and very broad, are quite those of Craleropus, and 
reach to half the length of the tail ; the inner toe is 
also rather shorter than the outer, and the claws 
(especially the hind one) very broad and fully 
* Teinminck describes this bird as a Pitta, with which 
genus, however, I consider it has no sort of relationship.
