Characters. — Shell subsplierical, oval, or flask-shaped, having a surface-ornamentation 

 of parallel costae, more or less strongly marked, generally extending from one end of the 

 shell to the other. Colour white to brownish. Length, Jjth to ^V.th inch. 



We regard this as the typical form oi Lagena, for its variations lead, in one direction, 

 into feebler forms, such as L. semisfriata, lavis, and glohosa ; 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 Lagena.
