Abstract
A study of well over one thousand specimens provided proof to put the conspecifity of the two supposed species originally described asHelobdella tricarinata andClepsine nilotica beyond all doubt. Evidence is presented which indicates that the striking changes in body-shape and drastic alteration in the appearance of the tuberculation at different stages of reproduction and nutrition combined with individual variation in tuberculation, annulation, and in the arrangement and pigmentation of the eyes were responsible for earlier confusion as to the identity of this species. Since the early accounts were incomplete and contained some important errorsBatracobdelloides tricarinata is redescribed and, for the first time, comprehensively figured.
