Skulls of Naja tripudians (A, B, C) and Bungarus candidus (D, E)
The Bungarus candidus is commonly known as the Malayan krait, and the Naja tripudians (now Naja kaouthia) is the monocled cobra. Both have venoms with nearly 100% neurotoxic action and were used in Dr. Noguchi’s research to compare against the hemotoxic venoms of other snakes.
