Abstract
This histological study of 141 specimens of adult Planaxis sulcatus from Karachi showed thepresence of only female gametes in gonadal follicles,supporting the conclusion of earlier workers that thespecies may be parthenogenetic. The gonadal folliclesof several snails were occupied by an unidentifiedtrematode parasite.
