OBSERVATIONS. 



I owe the opportunity to describe this new 

 species to Dr. Gould, who gave me specimens, 

 and the information that they are from Ver- 

 mont. It differs from L. elodes in having a 

 poHshed surface, expanded aperture, obsolete 

 lines of growth, translucency, and a deeper 

 fold upon the columella. It cannot be con- 

 founded with any other species.
