Tennessee, Georgia, and Alabama. 



Smaller and more delicate than n. spinosa ; strice more numer- 

 ous, thickly set with fine ciliae, which project at the periphery in 

 a fine fringe, and not like short triangular aculei, as in sjnnosa. 

 The umbilical region is less depressed, the parietal tooth much 

 more delicate, and does not overlap the peristome which stands 

 off from the shell, and is not appressed to it. H. edgariana is 

 much more solid and elevated, has the parietal tooth more de- 

 veloped, the peristome notched, as in H. hirsuta, but has about 

 the same diameter.
