Wapiti \Wap"i*ti\, n. [Probably the Iroquois name. Bartlett.]
(Zool.)
The American elk (Cervus Canadensis). It is closely related
to the European red deer, which it somewhat exceeds in size.
[1913 Webster]
Note: By some writers it is thought to be a variety of the
red deer, but it is considered a distinct species by
others. It is noted for the large, branching antlers of
the male.
