Cobra de Capello. Hooded Snake.

Characters. - The Cobra varies in length from 2 to 6 feet. The neck can be dilated so as to give the appearance of a hood covering the head. It is the snake usually employed by the snake-charmers. The fangs are canaliculated, and are in front of the superior maxillas, with smaller solid teeth behind them. The sixth upper labial scale is small, forming a suture with a very large temporal scale; there is generally a spectacles-like mark on the neck.

The poison of this serpent has been partially proved by the late Dr. Rutherfurd Russell. The virus must be collected as explained under the head of Crotalus.

Habitat. - Commonly found in Hindostan.

Preparation. - Solution in Glycerine, and subsequent attenuation in the same manner as Crotalus.
