 in 1789 by that of Gmelin, who latinised Latham's 

 description under the title of Emberiza platensis. 



Lesson in 1831 founded the genus Embernagra for two 

 birds in the Paris Museum, one name, Tanagra fabialatu, 

 being given without any description, the other described 

 under the title of Tanagra dumetorum with the following 

 description : — " Vert olivatre en dessus, gris-brun sur la
