Habitat. Motmtains of Georgia and North Cai'oliaa, 

 where it was collected by Bishop EUiott in great abim- 

 dance, under the bai-k of decayed stmnps and logs. 



Remarks. It is larger and more sohd than H. arbo- 

 rea, with a less spreading umbilicus and more obUque 

 apertiu-e. In general form, it is more like a large H. 

 indentata. It also has relations to S. placentula, but 

 has fewer whorls. It may be most readily recognized 

 by its transverse aperture, and thickened, somewhat 

 sinuous lip.
