Echis carinatus
In India, the serum prepared with the venom of monocled cobra "Naja kaouthia" has been found to be without effect on the venom of two species of kraits ("Bungarus"), Russell's viper ("Daboia russelli"), saw-scaled viper ("Echis carinatus"), and Pope's pit viper ("Trimeresurus popeiorum"). Russell's viper serum is without effect on colubrine venoms, or those of "Echis" and "Trimeresurus".
