title: An electrophoretic description of five species of squirrel.
abstract: 1. The blood serum proteins of five species of Nearctic squirrels were electrophoretically examined. 2. Protein polymorphism was detected in all the species described. 3. The use of the mean relative mobility of specific proteins was shown to be a valuable aid in distinguishing species.
