form and darker grass-green colour, generally more or less banded with 
dark brown. The edge and sutural region are always pale. The 
surface is on the whole smooth, but the epidermis is sometimes so 
cracked as to appear irregularly radiated with whitish lines. The 
shell figured by Philippi (Abbild. tab. 4, f. 9) as H. marginata, Mull., 
I should regard as a variety of this species.
