deep on the columella. The third in the palate, deeply im-

The surface is smooth and glossy; only in favorable light 

 under the lens oblique striae may be seen, never ribs; on the 

 last part of the last whorl there are a few stronger wrinkles. 



14&. T. claustralis opisthodon (Reinh.). PL 11, figs. 3, 4. 



The shell differs from claustralis by being more veutricose 

 in the middle, the finer rib-striation, stronger dentition (the 

 columellar tooth especially being very strongly developed), 

 and most notably by the very deep situation of the palatal 

 tooth, which is not visible in an oblique view in the mouth, 

 but always remains concealed behind the columellar tooth 

 (Reinhardt). 



Herculesbade, in southeastern Banat (Reinhardt).

14c. C. claustralis corcyrensis (Boettger). 



Shell generally larger, more cylindric, the apex more dis- 

 tinctly conic; whorls 7, costulate-striate, the striae closer. 

 Greatest diameter is in the middle (not in the upper part of 

 the shell) ; otherwise very similar to the type. Length 1% to 

 2, diam. % to % mm. (Bttg.). 



Corfu. Rather scarce, sieved from moss.
