Hab. In Sicilia, frequens (Pizl.). 
“Var. (3, quam libenter speciem peculiarem esse crederes, ad in- 
star Madreporarum cespitosa rupes vestit, et ipsa massas non sper- 
nendee molis constituit ; partem tantummodo attuli ultra 1’ longam, 
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 1 is a good transition to the fol- 
lowing species, from which perhaps it does not differ.
