Description
Elongate, medium-sized, subreniform, moderately convex, highest posterior to middle, dorsum strongly arched to nearly straight, venter concave, ends rounded, anterior margin generally narrower than posterior, LV slightly larger but RV may overlap along venter, surface smooth or finely punctate, shell substance cloudy white in Recent forms. Inner lamellae broadest anteriorly; radial canals few, simple, widely spaced. Males slightly larger ·than females, but nearly of same proporlions; some species parthenogenetic (40, 68). [Freshwater.] [BRADY'S (1846) designation of Cypris reptalls as type species of Candona takes precedence over selection of this same species by BRADY & NORMA" (15) as the type species o'f Erpetocypris, and likewise of their designation of Cypris candida O.F.MuLLER, 1776; as type species of Candolla; accordingly Erpetocypris and SARS' Herpetocypris. which is an invalid emendation of Erpetocypris, must be classed as objective junior synonyms of Calldolla.]
