With respect to the term Carnassier, used by Cuvier for his third 
order, some observations will be found in our second volume, at the 
commencement of the supplementary matter on the order. 
ORDER I.— B 1 ! MANA. 
This order contains only one genus, and a single species, with its 
varieties, as here under :

Varieties. 
1. Caucasian 
2. Mongolian 
3. Ethiopian 
4. Malayan? 
5. American? 
Only the first three varieties are considered by Cuvier as pos- 
sessing sufficiently distinctive characters to deserve separate descrip- 
tion. “ The Malays,” he says, “ pass by imperceptible shades into 
their neighbours, the Caucasian Hindoos on one side, and the Mon- 
golian Chinese on the other.” The Americans also want that precise 
and constant character necessary to constitute a peculiar race. For 
these reasons we have marked the two last varieties with a query. 
In this order we have given even the varieties ; in the others we 
can go no farther than the subgenera, with one specific example of 
each : our space compels us to this arrangement.
