22 HELICIDiE. 



dennis raised into acute strire, wliich at the sutiu-e aud 

 carina ai-e produced into short cilia or bristles ; these 

 epidermidal strii^ are sometimes seen beneath, but less 

 distinctly, being often obsolete in the mature shell ; basal 

 surface convex, but indented in the umbilical region ; 

 spii"e slightly convex ; whorls five and a half, rather flat, 

 last one suddenly but slightly deflected ; apertm-e very 

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

 slender, tongue-shaped tooth, which extends nearly across 

 the whole width of the apertm-e ; peristome callous, 

 margins slightly but distmctly reflected, and thickened 

 within, basal margin shghtly arcuate, but entire. 



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



Habitat. Habersham Coimty, Georgia, where it was 

 collected by Bishop EUiott. Northwestern Georgia, Mr. 

 Pierce. 



Remakes. Smaller and more dehcate than H. spi- 

 nosa ; strife more numerous, thickly set with fine cihae, 

 wliich project at the periphery in a fine fi-inge, 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 hp, which stands 

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

 gariana is much more sohd and elevated, has tlie parie- 

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

 liirsuta, but has about the same diameter.
