Corrections to Mr. Vigors's Sketches in Zoology, 519 



ferred upon the same groups. In Brazilian and Javanese 

 Zoology this is the case to a very great extent ; more particularly 

 with respect io the Zoology of the former country, from whence a 

 vast accession of new subjects has lately poured into every part 

 of Europe. The above Brazilian genus, which I characterized in 

 the former volume of this Journal, is one of those forms which 

 has been considered by continental naturalists worthy of being 

 separated into a distinct group ; and it forms the genus Bidens 

 of Dr. Spix, as published in his splendid work on Brazilian Orni- 

 thology. In this case however there can arise but little confusion 

 as to the adoption of the generick name for the group ; that of 

 Bidens having long since been appropriated to Botany : it is 

 in fact a Linnean genus. 



The same observations may be made respecting the group of 

 Psittacara^ characterized at Vol. II. p. 388, of this Journal. 

 The species which compose that group have been referred to a 

 new genus of that gentleman, under the name of Aratingu. 

 Here again we may easily reconcile the apparent clashing of these 

 two names. My group extends only to the South American spe- 

 cies of Parrakeets^ the orbits of whose eyes and a greater or less 

 extent of whose cheeks is naked : while Aratinga not only 

 embraces these, but includes a considerable number of the long- 

 tailed ParrakeetSy which have the cheeks and orbits feathered. 

 This latter group forms a very extensive division of the family, 

 and is one which I had marked out for characterizing. If we 

 limit the name of Aratinga io this latter group, and retain that of 

 Fsittacara to. the true Perruche-Aras^ we shall avoid all confu- 

 sion in designating these divisions. 



Although some confusion may at times arise in the variety of 

 names which thus may be conferred on the same forms , yet it is 

 in general a gratification to naturalists to find the justness of their 

 views, respecting the separation of groups, confirmed by the cor- 

 responding sentiments of their fellow labourers in the same de- 

 partment of science. In the present instance I myself feel much 

 pleasure in observing that those above-mentioned groups are con- 

 sidered by such an acute ornithologist as Dr. Spix. to be worthy 

 of separation ; and more particularly the former group of //ar»
