 Fig. 236. Metoptoma instabilis. a } under side ; 6, side view. 



Description. Shell small, depressed conical ; apex acute, slightly 

 incurved, situated over the anterior margin ; aperture circular ; surface 

 finely striated parallel to the base. 



Width of an average specimen, 8 lines ; height, 4 lines. 



The above relates to a symmetrical individual, but there are many 

 specimens with the base more or less oval, and the apex turned either to 

 the right or left, besides being more flattened on one side than the other. 

 I regard these as being all deformed individuals of the same species.
