The first volution is less ventricose and thinner, and the 
mouth not so patulous, but it has no character to entitle 
it to be considered as distinct. It cannot be H. limosa, as

accord with Linneus’s referent to Gualt. Test. t. 5. f. H. 
or with his descriptions of that species in the two edi- 
tions of his Fauna Suecica—* Testa. oblongiuscula, an-
