Clausilia parvula. Turton, Zool. Journ. 11. p. 556. 



Jeffreys, Linn. Trans, xvi.p. 352. 



Clausilia minima. Pfeiffer, t. S.f. 35. 



Shell three eighths of an inch long, slender, of a dark 

 brown, with nine volutions which are hardly raised, 

 quite smooth, except the lower half of the lower 

 volution which is sometimes slightly striate : aper- 

 ture narrow oval, oblique, with the margin thick 

 and white, and detached all round. 



This is no doubt the shell mentioned by Leach, 

 Mollusc, p. 121, as having been received from the 

 Provost of Eton, but which in consequence of the 

 imperfect formation of the mouth he was not able 

 to characterize. Our most perfect specimen was 

 taken at Torquay. It much resembles the Cl. 

 corrugata of D rap. p. 70. t. 4./. 11, 12, but is not 

 half the size and has only nine volutions. We have 

 also received specimens from Mr, Alder of New- 

 castle.
