Vol. ii. p. 309. Fam. PROSERPINLTLE. 



The observations of Messrs. Bland, Chitty, Poey, Gundlach, 

 and Gray have shown that the eyes of Proserpina are at the 

 outer base of the tentacles, as in Oyclophorida, and that the 

 animal is inoperculate. The position of the family seems to be 

 after the Ellobiida, where Pfeiffer has placed it. Dr. Gray has 

 separated P. eolina, and made it a genus under the name Ceres. 



Genus CERES, Gray. 



Shell helicinreform, carinate, rugose above, covered with a thin 

 epidermis, base furnished with a shining callus ; aperture Iamel- 

 liferous, peristome straight, somewhat thickened.
