Title from caption.
"March 21, 1958."
Specimens collected by Ottys Sanders.
"The hologyny of D. sandersi is specific rather than sporadic, diagnostic in the genus, possibly unique among earthworms with biparental reproduction and older than in the parthenogenetic Enantiodrilus borellii. Postparthenogenetic evolutionary changes are responsible in E. borellii and Pontoscolex corethrurus for conditions previously regarded as evidence for consecutive hermaphroditism. Postparthenogentic sterilization of male gonads and conversion of testes to ovaries probably is gradual"--P. 8.
