seems to be some confusion in respect to M. Kuhl's reference to 

 P. discolor of the " Index Oniithologicus." He refers that name 

 to the Perruche Latham of M. Le Vaillant {pi. 62.), Psitt. La- 

 thami, Bechst., an apparentl}^ distinct species ; and he assigns the 

 denomination of Psitt. humeralis, Bechst., to the Psitt. discolor, 

 or Red-shouldered Parakeet of Latham, White, and Phillips.

The bills of this species and of the next are in a slight degree 

 more rounded at the culmcn than that of the typical species 

 A^. discolor : the wings are also somewhat less acuminated, and 

 the tail flatter and more rounded at the apex. In these parti-
