19) Charpcntier 1837 (Catal. des moll. lerr. et fluv. de

 Ag. , Hyalinia Ag.), Bulimum (subgenera: Polyphemus, Folliculus 

 Ag., Bulimulus), Pupam (subg, Eucore Ag., Sphyradium Ag., 

 Chondrus Cuv.), Clausiliam, Vertiginem. 



20) Held 1837 (Isis p. 905.) Pulmonaceorum familias enu- 

 merat: Helices (genera: Cepaea, Coenatoria, Cingulifera, Corneola, 

 Lenlicula , Xerophila, Frulicicola, Trochiscus, Gonostoma, Tra- 

 gomma, Patula, Polita), Bulimos [genenw Zebrina, Merdigera), 

 Pupas (genera: Gonodon, Granaria, Orcula, Torquatella ). — Re- 

 liquae familiae publico non traditae sunt. 



21) D'Orbigny 1837. (Moll. canar.) nomen gallicum familiae 

 male vertit in: Colimacidae. Eodem nomine 1841 (Moll. cub. I. 

 p. 137. 140.) in secunda familia Pulmobranchiatorum genera ad- 

 mittit: Vitrinam, Succincam, Helicem, Achatinam , Bulimum, 

 Pupam. Clausiliam. 



22) Potiez et Michaud 1838 (Galerie de Douai I. p. 64.) 

 in familia Cochlearmn genera habent sequentia: Vitrinam, Succi- 

 neam, Helicem, Achatinam, Bulimum, Pupam, Clausiliam, Ver- 

 tiginem, Partulam. 



23) Sowerby 1839 (Conch.Man.) et1842 (ib. ed. IL p. 1 12.) 

 familiam Colimaceorim in Trachelipodibus adoptat et in 3 sectio- 

 nes dividit, quarum prima genera continentur sequentia: Suc- 

 cinea, Helix, Anastoma, Streptaxis, Bulinus, Achatina. Pupa, 

 Clausilia. (In secunda et tertia seclione Auriculacea et Cyclosto- 

 macea tractantur.) — In explicatione figurarum (p. 302.) genera 

 adduntur sequentia: Proserpina, Polygyra, Carocolla, Achatinella, 

 Polyphemus, Azeca, Alaea, Vertigo, Megaspira, Balea et (p. 311.) 

 Stenopus. 



24) Gray 1840 (Manual [). 101.) in Pneumonobranchiatis 

 inoperculatis terrestrihus duas familias dislinguit: Arionidas el 

 fJelicidas, quarum in subfamiliis Limacinorum , VUrininornm, 

 Teslacellinorumet Helicinorum sequentia tractantur genera: Limax, 

 Vitrina, Testacella, Helix, Zonites, Succinea, Bulimus, Zua, Azeca, 

 Achatina, Pupa , Verligo, Balea, Clausilia. — In Synopsi Mus. 

 Rril. (ed. 1840 et) 1842 (p. 67 et 90.) systema ab auclore fusius 

 cxpositum est. Genera a me Heliceis adseripla in rluahus fainilii^^
