Nerita. Troschel discusses the subgenera, and proposes to distin- 
guish them chiefly by the teeth in the aperture of the shell, rather than 
by the sculpture of the operculum ; the radula exhibits some differences, 
but they are scarcely available for characterizing the subgenera ; he 
describes and figures the radula of N. polita (L.), peloronta (Lam.), lineata 
(Chemn.), birmanica (Phil.), muUijugis (Menke), marmorata (Reeve), 
picea (Reel.), ynldii (Reel.), plicata (L.), ornata (Sow.), versicolor (L.), 
plexa (Chemn.), exuvia (L.), hernhardi (Reel.), tessellata (Gmel.), exarata 
(Pfr.), planospira (Anton), signata (Macleay), stella (Chemn.), beaneana 
(Reel.), variegata (Chemn.), nigerrima (Chemn.), commanotata (Reeve), 
and albiciUa (L.). Gebiss d. Schnecken, ii. pp. 183-196, pi. xvii. figs. 3-20, 
pi. xviii. figs. 1-7.
