Conulus), Discus, Helicella; inter Vitrininas genus : Pfeifferia 



Gray ; inter Helicinas (Helicidarum subfamiliam) genera: Strep- 



taxis, Stylodonta (subgen. Janira, Erepta), Helix (subgen. Ga- 



laxias, Camaena), Eurycratera (subgen. Leiostoma, Polymita), 



Helicostyla (subgen. Callicochlias , Corasia, Axina, Chloraea, Oxy- 



chona), Acavus (subgen. Tachea, Phasis, Geotrochus), Cochlea 



(subgen. Otala, Parthena, Dialeuca, Coryda), Lucerna (subgen. 



Labyrinthus, Isomeria, Dentellaria, Serpentulus Klein, Obba, 



Semicornu Klein, Erigone), Macrocyclis (subgen. Ampelita, Ly- 



sino'e Ad., Eurystoma, Vallonia), Solaropsis , Anchistoma {subgen. 



Mesodon, Polygyra, Drepanostoma , Polygyratia Gr., Corilla Ad.), 



Iberus (subgen. Lampadia, Macidaria, Helicigona, Campylaea, 



Arianta, Elona Ad., Aegista, Thea), Ochthephila (subgen. Acti- 



nella), Hygromia, Theba (subgen. Ints); inter Stenopidas genera: 



Stenopus , Nanina (subgen. Hemiplecta , Ryssota, Microcystis, 



Macrochlamys Rens. , Pachystyla Mdrch, Cysticopsis Morch), 



Ariophanta, Paryphanta (subgen. Amphidoxa). — In synopsi 



omnium specierum (Malak. Bl. 1855. p. 112) ex affmitate natu- 



rali distributarum, genus Naninam (sectiones: Vitrinella Gray, 



Pfeifferia Gray, Stenopus Gidld., Rensonia Pfr., Xesta, Hemi- 



plecta ct Rhyssota Alb., Ariophanta Desm. et Paryphanta Alb.) 



sejunxi, et in genere Helice (sensu strict.) praeter sectiones 



ab aliis institutas novae propositae sunt sequentes: Ammono- 



ceras, Dibothrion, Actinaria, Plagioptycha , Sculptaria, Systro- 



phia, Oxytes, Eremina, Thersites. — Cl. Schmidt (1855 Sty- 



lomm. p. 1 1 ) species in Pomatia, Archehce, Macularia Alb. et 



Ibero Montf. enumeratas, in una sectione nomine Pentataeniae 



eomprehendit. — Cl. Moquin-Tandon 1855 (Moll. de France II) 



speeies nostri generis in Galha viventes in duobus generibus 



enumerat: Zonite (sectiones: Conulus, Calcarina, Aplostoma, 



Verticillus) et Helice (secliones: Delomphalus, Caracollina, Tri- 



gonostoma, Helicodonta, Petasia, Arianta, Corneola, Chilostoma, 



Vortex, Lucena , Otala, Tachea, Cryptomphalus , Helicogena, 



Coenatoria, Cantareus, Fruticicola, Hygromane , Zenobia, Jacosta, 



Helicella, Heliomane, Theba, Cochlicella). — Cl. Albers tandem 



nuperrime (Malak. Bl. IV. 1857. p. 91) genus Hyalinam Fer. iUu- 



stravit et descripsit. Sectiones ei sunt: Euhyalina (//. cellaria), 



Mesomphix [H. olivetormn) et Gastrodonta H. interna Say.).
