H.forsythi is somewhat intermediate between turrentina and rtrir 

 </ta var. fascolabiata. From surrentina the bluish-white color, le*. 

 rounded, more sloping form, the body-whorl more swollen below 

 rougher sculpture, different color pattern, and especially the more 

 circular aperture distinguish it. From fusco /< ibi<it>: it w separated 

 by the more sloping form, narrower hist whorl, rounder, more oblique 

 aperture and notably diverse sculpture.
