RED-BEAKED TOUCAN. 
The Toucan, properly so called, according 
to BufFon, contains only five known species ; 
but this genus subdivides itself into the Tou- 
cans and the Aracaris, These differ from 
oach other, in the first place, as to their size, 
the Toucans being much larger than the Ara- 
earis; secondly, with respe6l both to the di- 
mensions and substance of the bill, that of the 
Aracaris being much the largest, hardest, and 
most solid; and, lastly, in the tail, which the 
Aracaris have long, and very sensibly tapered, 
whereas it is rounded in the Toucans^ The 
names and distin6lions of the two varieties are 
said to have originated with the Brasilians: 
but the natives of Guiana, have made the 
same discrimination ; only calling the Tou- 
cans the Kararouima, and the Aracaris the 
Grigri» In treating generally of these t^^•o 
tribes, under the title Toucans, BufFon maiwcs 
th-e following preliminary remarks.
