The typical var. swbconica though not showing nearly 
so high a coetticient as the sub-vars. a/ta and chambardi, Rigdon en aee 
is in appearance much more conoid, due chiefly to the — var. suéconica Monts. 
much more depressed and rounded whorls, which gives a Mondello, Sicily (Marquis 
greater apparent height to the shell. Monterosato).
