In the Gulf of Siam there occurs a small, hyaline form of this 
species, which differs from the preceding species in wanting the big 
puncta between the ribs.

House broadly-campanulate, ventricous, with

This delicate species of which I have only 
seen a single specimen seems to be nearest to Cytt. simplex Cleve, 
from which it is easily distinguished by its ventricosity.
