Massasauga Sistrurus catenatus was formerly listed by COSEWIC as eastern massasauga Sistrurus catenatus catenatus. The currently recognized name of this species isSistrurus catenatus, the massasauga (Crother et al. 2000). Massasaugas in Canada are of the subspecies S. c. catenatus (the eastern massasauga), which also occurs in several U.S. states. For the purposes of this COSEWIC report, the Canadian subspecies, the eastern massasauga, may be considered synonymous with S. catenatus, the Massasauga (Crother et al. 2000).
