Characters.—Shell subspherical, oval, or flask-shaped, having a surface-ornamentation 
of parallel costee, more or less strongly marked, generally extending from one end of the 
shell to the other. Colour white to brownish. Length, 3th to th inch. 
We regard this as the typical form of Zagena, for its variations lead, in one direction, 
into feebler forms, such as ZL. semistriata, levis, and globosa ; and on the other hand we 
have varieties with reticulated, hispid, and granular ornament; we have also compressed 
forms and elongate varieties, departing more or less widely from the middle type pre- 
sented by the ovate and characteristically costate Lagene.
