\Bo"a con*strict"or\ [NL. See {Boa}, and
{Constrictor}.] (Zo["o]l.)
A large and powerful serpent of tropical America, sometimes
twenty or thirty feet long. See Illustration in Appendix.
Note: It has a succession of spots, alternately black and
      yellow, extending along the back. It kills its prey by
      constriction. The name is also loosely applied to other
      large serpents which crush their prey, particularly to
      those of the genus Python, found in Asia and Africa.
