 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,

 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, Succineara, Helicera, Achalinam, Bulimum, 

 Pupam, Clausiliam. 



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

 in familia Cochlearum genera habent sequentia: Vitrinam, Succi- 

 neam, Helicem, Achatinara, Buliraura, Pupara, Clausiliam, Ver- 

 tiginem, Partulam. 



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

 familiam Colimaceorum 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 sectione 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 p. 101.) in Pneumonobranchiatis 

 inoperculatis terrestribus duas farailias distinguit: Arionidas et 

 Helicidas, quarum in subfamiliis Limacinoruni, Vifrinijiorum, 

 Testacellinorum et Helicinorum, sequentia tractantur genera: Liraax, 

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

 Achatina, Pupa, Vertigo, Balea, Clausilia, — In Synopsi Mus, 

 Brit. (ed. 1840 et) 1842 (p. 67 et 90.) systeraa ab auctore fusius
