cidua partim obtecta; spira turbinato-conica, apice obtusulo; sutura subim- 
pressa; anfractus convexi, ultimus subascendens, magnus, lamellis longitudi- 
nalibus, compressis, prominentibus, pone marginem externum elegantissime 
ornatus; apertura subovato-circularis; peristoma breviter expansum, in adultis 
continuum, in vicinio anfractus penultimi subangulatum. — Operculum vide 
in descriptione speciei. — Animal? — Forma insignis testa et operculo 
inter Cyclophoros et Cyclostomata (genera inter se animalis structura dis- 
crepantia) quasi media. Operculum operculo generis Cyclostomatis forma 
subovali et anfractibus simillimum, sed corneum nec testaceum. Testa tenui- 
tate, colore et aspectu Cyclophoris sat vicina, charactere peculiari lamella- 
rum anfractus ultimi gaudet. ( Cyclophorus foliaceus Ch. eodem charactere 
paululum gaudet, sed operculo typum generis Cyclophori omnino exhibente 
valde discrepat.)“
