22 HELICIP.T;. 



derails raised into acute stride, which at the suture and 

 carina are produced into short cilia or bristles ; these 

 epidermidal striae are sometimes seen beneath, but less 

 distinctly, being often obsolete in the mature shell ; basal 

 surface convex, but indented in the umbilical region ; 

 spire slightly convex ; whorls five and a half, rather flat, 

 last one suddenly but slightly deflected ; aperture very 

 oblique, transverse, ear-shaped, narrowed by a rather 

 slender, tongue-shaped tooth, which extends nearly across 

 the whole width of the aperture ; peristome callous, 

 margins slightly but distinctly reflected, and thickened 

 within, basal margin slightly arcuate, but entire. 



Diam. maj. 10 mill. ; diam. min. 9 mill. ; alt. 6 mill. 



Habitat. Habersham County, Georgia, where it was 

 collected by Bishop Elliott. Northwestern Georgia, Mr. 

 Pierce. 



REMARKS. Smaller and more delicate than H. spi- 

 nosa ; striae more numerous, thickly set with fine cilise, 

 which project at the periphery in a fine fringe, and not 

 like short triangular aculei, as in Spinosa. The umbi- 

 lical region is less depressed, the parietal tooth much 

 more delicate, and does not overlap the lip, which stands 

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

 gariana is much more solid and elevated, has the parie- 

 tal tooth more developed, the outer lip notched, as in H. 

 hirsuta, but has about the same diameter.
