Genus 3. PARMACELLA, CWer. 



Animal ; oblong, with a somewhat gibbous, fleshy shield on the 

 middle of the bach, enclosing a shell ; head, with four tentacles, 

 of which the upper pair are the larger. 



Shell ; rudely ear-shaped, covered with a horny epidermis ; spire 

 short, sometimes irregularly papillary. 



In this genus the pulmonary cavity and fleshy shield, enclosing a 

 shell for its protection, is situated about the middle of the animal. The 

 shell is of much more uncouth growth than that of Testacella, the spire 

 being irregular and rudely papillary. We have no Parmacella in Britain, 

 nor is it — nor is Testacella — known in North America. The first specimen, 

 P. Olivieri, was discovered by M. Olivier in Mesopotamia ; another spe- 

 cies, P. palliolum, was received from Brazil ; a third, P. cali/culata, was 

 discovered by MM. "Webb and Berthelot in the Canary Islands, and Cuvier 

 speaks of " some others from India." We only know of the following.
