Abstract 1. Two hemorrhagic toxins of mol. wt 27,000 (B1) and 27,500 (B2) and pI 9.8 and 5.2 respectively were isolated from Crotalus basiliscus venom. 2. The two proteinases did not cross-react antigenically. 3. Both toxins caused hemorrhage in mice and each was capable of hydrolyzing hide power azure, casein, collagen and fibrin. 4. B1 hydrolyzed the A alpha, B beta and gamma chains of fibrinogen. B2 hydrolyzed the A alpha and B beta chains of fibrinogen, but not the gamma chain. 5. Both proteinases inactivated guinea pig complement.
