Haje \Ha"je\ (h[aum]"j[-e]), n. [Ar. hayya snake.] (Zool.)
   The Egyptian asp or cobra (Naja haje.) It is related to the
   cobra of India, and like the latter has the power of
   inflating its neck into a hood. Its bite is very venomous. It
   is supposed to be the snake by means of whose bite Cleopatra
   committed suicide, and hence is sometimes called Cleopatra's
   snake or asp. See Asp.
