Rough-tailed Sand Boa or Rough Scaled Sand Boa (Gongylophis conicus) is a short, stout bodied species of snake found in Pakistan, Nepal, India, and Sri Lanka. They were once classified in the genus Eryx, but have since been moved to the genus Gonglyophis. In the Indian region they can be mistaken at first glance for either the Indian Python or the deadly Russell's Viper.
