"Var. /3, quam libenter speciem peculiarem esse crederes, ad in-

 6-7'" latam." — Philippi. 



Philippi never observed varices in this species. The specimens I 

 have compared showed generally one or two varices in the last and 

 penultimate whorls. The variety ?; is a good transition to the fol- 

 lowing species, from which perhaps it does not differ.
