sunif Geoff., equal or squared tail, naked cheeks, and tuft on 

 head. 



Each of these divisions are subdivided, according as the spe- 

 cies which they comprehend are of America, of India, of 

 Australia, or of an unknown country. In that of the para- 

 keets, (Conurus,) M. Kuhl has admitted the groups pro- 

 posed by Le Vaillant, but rendered them subordinate to the 

 geographical divisions above mentioned. This is the only 

 part of M. KuhPs system that seems objectionable. 



The uncertain or doubtful species M. Kuhl has divided 

 into two groups, according to the method of Latham. 1st. 

 Those with lonff tails. 2d. Those with short. Macrourus 

 and Brachyurus. Each of these divisions is afterwards sepa- 

 rated geographically. • . * 



We shall now finally notice the new genera introduced 

 by our distinguished countryman, Mr. Vigors, and his able 

 coadjutor, Dr. Horsfield, in the family of the psittacidse. 



1. Pal^ornis, Vigors. The type of which is Psittacus 

 Alewandri. 



2. LoRius, Vigors. The type P. Domicella. 



3.' Brotogeris, Vigors. The type P. Pyrropterus. 



4. PsiTTACARA, Vigors. The parrakeet maccaivs. 



5. Platycercus, Vigors. The chief generic character is 

 the broad and depressed tail. 



6. Trichoglossus, Horsfield. Filamentous tongue. *,*»'" 

 7- Nanodes, Horsfield. A beautiful group, belonging 



to Australia, so called from their diminutive size. 



8. Androglossa,. Vigors. 



9. Calyptorhyncus, Horsfield. 



Besides these genera, Mr. Vigors has adopted, from other 



writers, the following : Psittacus, Microglossum, Plycto- 



■ LOPHUs Mackocercus, Pezoporus, and Psittacula. Of all 



these genera he makes five sub-families, viz., Psittacina, 



Plytolophina, Macrocercina Palceornina, and Psittaculina.
