HERMAPHRODITISM IN EURYCEA BISLINEATA

Abstract
1. True hermaphroditism occurs in approximately constant proportions in every developmental stage of Eurycea bislineata from typical larval to adult. 2. The percentage of occurrence of hermaphrodites in this species, based upon the examination of 1,113 individuals, is 1.35 per cent. 3. There are now on record 18 cases of hermaphroditism in urodeles. The first is that of La Valette St. George ('95) in Triton tœniatus, the second is that discovered by Chapin ('15) in Eurycea bislineata, the third is that of Křizenecky ('17) in Triton cristatus, and the other 15 cases, in Eurycea bislineata, are presented in this paper.
