p. 463 . 476 : „testa oblonga, interdum cylindracea, rare ovata, imperforata i 
vel anguste perforata, unicolor; apertura ovata, fere circularis; perist. sim- 
plex, continuum, ad anfr. penultimum adnatum aut disjunctum, interdum vix 
porrectum; anfr. ultimus saepe ad peripheriam subangulatus. — Animal
