However, as it renders the method more 

 eafy, I have ranked them in a diftinfl: 

 genus : for it is very fertile in fpecies, 

 the common land Snails and many others 



numbering in it. 



The Snails with a produced or length- 

 ened clavicle or turban, (Clavicula loii- 

 giore) which I (hall particularly call Tur- 

 bo, form the fourth genus, Thefe mofi: 

 generally have a perfeft round mouth ; the 

 columella or inner lip is not much faced 

 outwards, and the body fpire is very bel- 

 lied, fo that the turban is not infenfibly, 

 but fuddenly or difproportionately pro- 

 duced from it, like as in the Buccina.^ 

 PL III. fig. 12. 



The arrangement and names this genus 

 of turbo bears with fyftematifts is as fol- 

 lows. Lifter places them as a feftioii of 

 the Snails. Gualtieri calls them Cochlear 

 Marinje Terreftriformes. Rumphius, Ai- 



gcaville^
