A
buffalo is one of several species of large bovine, including
Bubalus bubalis (the river [water buffalo]
?),
Bubalus carabanesis (the swamp [water buffalo]
?),
Bubalus depressicornis (the lowland
anoa),
Bubalus quarlesi (the mountain
anoa), and
Bubalus mindorensis (the tamaraw
?).
Note that neither Syncerus caffer (the [Cape buffalo]?) nor Bison bison (the [American bison]?) are, in fact, buffalos.
