XIV. ACHATINA. 



Shell oval-oblong, or somewhat cylindrical, obtuse at 

 the tip : aperture longitudinal, oval, entire at the 

 base ; the outer lip thin, and never reflected : 

 pillar smooth, simple, truncate at the base : oper- 

 culum none. 



The abruptly truncated termination of the pillar or 

 outer lip will immediately distinguish this genus 

 from the Bulimus, to which it is in other characters 

 so nearly allied. 



71. ACHATINA Acicula. Shell slender, smooth, 

 polished, white, with six flat volutions : the lower 

 one as long as all the others.
