Seconcll_y, the quasi-cosmopolitan genus Erismatura has 2 repre- 

 sentatives peculiar to the Neotropical region — namely, E. ferruginea 

 and E. dominicana. 



After deducting these two categories, the remaining 29 species 

 form the Antarctic division of the Neotropical Anatidse, and consist 

 mostly of species belonging to genera also found in the north — e.g. 

 Bernicla (6), Cygnus (2), A7ias (2), Querquedula (8), 'Dafila (2), 

 Mareca (1), Spatula (1), and Mergus (1). Adding these together.
