1 cannot quite make out this species. The describer says 

 nothing of the coloration of the tail, whether identical with 

 that of Th. doliatus or not.

This bird is certainly distinct from the doliatus of Cayenne, 

 and I think also from the true radiatus of Vieillot, ex Azara. 



It is hardly likely to be the same as any of the New Grana- 

 dian species described by M. de Lafresnaye, the localities 

 being so distant. 



I have not yet seen the female, which, to judge by Prince 

 Maximilian of Neuwied's description and Spix's figure, must 

 be quite different from the female of doliatus. The male bird 

 may be at once distinguished from the latter species by the
