- n Vipera type genus of the Viperidae
Century Dictionary and Cyclopedia
- n vipera A genus of serpents, giving name to the Viperidæ. Formerly it was applied with little discrimination to a great number of venomous viviparous species and others. It is now restricted to a small genus of the family Viperidæ, of which the common viper of Europe (V. aspis, V. communis or Pelias berus) is the type, having the urosteges two-rowed and the nostril between two plates. Also called Pelias. See Viperidæ, and cuts under adder and viper.
