Mr. Boys favoured us with this fhell, with a reference 

 to Walke r's figure : from the appearance we have little 

 doubt, but it is the fry of fome fpecies of land Helix. 



The preceding fix (hells, which we have been obliged

 ing come under our examination, the laft excepted) are 

 reprefented to be very minute.
