XIV INTRODUCTIO. 



jj;enera noinine Vitrinae conjunxerunt, id quod eti;o quoque feci, 

 Simpulopsin Beckii (auctori subgenus Succineae), inter Vitrinani 

 et Succineam ambiguam, sed ad Vilrinam ex mea sententia polius 

 referendam, huic generi adnumerans, — Plures autem species 

 ab auctoribus ob testae similitudinem Vitrinae adscriplae, prae- 

 sertim capenses, ad Helicem forsan meliore jure in posterum 

 referentu!-.

Testa Succineae a Bulimis columella simplice praeditis (B. 

 gallina-sultana etc, ) generico charactere vix ullo distingui potest, 

 quare olim (conf, Proc. Zool, Soc. Lond, 1842. p. 187 et 188, et

 serius autem (Symb. III, et in hoc libro) e notis de animalium
