Haye \Ha"ye\, n. [Ar. hayya snake.] (Zo["o]l.)
   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}.
