Abstract
Electrophoresis is used to compare the venoms of 155 individuals of the 3 new world Agkistrodon spp. [A. contortrix, A. piscivorus, A. bilineatus]. Electrophoretic patterns vary geographically, both within and between species. Variation of some pattern bands makes them useful as taxonomic tools; others show so much variance that they are not taxonomically useful, but may be useful in studying the genetic diversity of populations.
