seems to be some confusion in respect to M. Kuhl’s reference to 
P. discolor of the ** Index Ornithologicus.” He refers that name 
to the Perruche Latham of M. Le Vaillant (pl. 62.), Psitt. La- 
thami, Bechst., an apparently 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 culmen than that of the typical species 
N. discolor : the wings are also somewhat less acuminated, and 
the tail flatter and more rounded at the aper. In these parti- 
culars it evinces a gradual approach to the next genus, Platy- 
cercus. The birds of this latter genus are observed to feed upon 
the ground; and the two species now before us are generally 
found in a similar situation as we are informed by Mr. Caley.
