It is Still my aim to show the deficiency of our knowledge, 

 in the hope that observers will supplement the information as 

 far as they are able.

" Some authors seem to have considered this as the Helix 

 hicorum of Linnaeus, but it certainly admits of much doubt. 

 Gmelin did not think so, for he has given all the synonyms of 

 this shell to his H. aspersa, and has made his H. luconim a very 

 different shell, a figure of which is given in Lister's Conchology, 

 tab 1058, fig. i.
