HELIX ELLIOTTI, REDFIELD. 



Testa angust6 umbilicata, orbiculato-depressa, striattila, virente- 

 cornea, subdiapkana, subtus nitida ; spira convexa, paruru elata ; 

 anfractibus quinque, convexiusculis, ultimo vix depresso ; sutura 

 irnpressa ; apertura obliqua, lunato-circulari ; peristomate sinuato, 

 acuto, intiis incrassato. 



SHELL with rather a narrow umbilicus, depressed- 

 orbiculate, with fine transverse striae, greenish horn- 

 colored, hardly translucent, shining beneath ; spire con- 

 vex but not much raised : whorls five, rather convex, 

 last one sometimes very slightly depressed at the aper- 

 ture ; suture deeply impressed ; aperture very oblique, 

 lunate-circular, peristome a little sinuate, acute, but 

 thickened within. 



Diam. rnaj. 9 mill. ; diam. mm. 8 mill. ; alt. 4 mill, 

 Habitat. Mountains of Georgia and North Carolina, 

 where it was collected by Bishop Elliott in great abun- 

 dance, under the bark of decayed stumps and logs. 



REMARKS. It is larger and more solid than H. arbo- 

 rea, with a less spreading umbilicus and more oblique 

 aperture. In general form, it is more like a large H. 

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

 has fewer whorls. It may be most readily recognized 

 by its transverse aperture, and thickened, somewhat 

 sinuous lip.
