Obs. Forma insignis testa et operculo inter Cyclophoros 

 et Cycîostomata (gênera inter se animalis structura dis- 

 crepantia) quasi média. Operculum operculo generis Cy- 

 clostomatis forma subovali et anfractibus simillimum, 

 sed corneum nec testaceum. Testa tenuitate, colore et 

 aspectu Cyclophoris sat vicina, charactere peculiari la- 

 mellarum anfractus ullimi gaudet (!).
