Habitat in Brasilia. 



Amici mei Georgii Such, Medicinae Doctoris, Socletatis Linne- 

 anae Socii, scientiae Oruithologicae studiossimi, haec species, inter 

 complures alias adhuc ineditas, a se in Brasilia detecta, nomine 

 distinguatur. 



There are several other species which have been hitherto indis- 

 criminately scattered in different genera of the Linnean system, 

 vphich by their habits and manners, and a general conformity in 

 external character, are closely allied to the present group, if not 

 at once referable to it.* Among these are the following birds 

 which accord with the essential characters of Le'istes, although 

 in some minute points they evince a partial deviation from the 

 typical species. Their bills are in a slight degree shorter, and 

 seem to approach more closely to those of the Emberizee and 

 Fringillce; and their wings partially differ in structure, the first 

 quill feather being somewhat shorter than the second. They ap- 

 pear to form the extreme groups of the present family o{ Sturnidce, 

 and to unite it with the neighbouring FringilUdce. 



* The geuus Ploceus of M. Cuvier is intimately allied also to the genus 

 Leistes, and most probably will be found to come into the present subfamily 

 among those birds which exhibit the same modification of form as that genus. 

 But the characters o{ Ploceus unite it also so closely to some of the FringilUdce^ 

 that I cannot say whether it may not belong to that family, and be the bond 

 of connection between it and the present group of Sturnidee. I shall only 

 therefore at present refer to tlia affinity between these two genera.
