Remarks on Certain Species of N. A. IlelicidcB. 127 



ing with his description, I do not pronounce it faulty, but 

 assume that sooner or later a form such as he must have had 

 before him will come under my notice. 



H. loBvigata is a very variable species, — the following fo^ms 

 are in my cabinet : — 



a. Diam. maj. 14, min. 12, Alt. ^ mill. Hah. unknown. 



b. " " 17 " 14 " 8 " " N. Carolina. 



pale yellowish horn colored, polished, irregularly striated, 

 « wrinkled." 



c. Diam. maj. 17, min. 14, Alt. 6 mill. Hah. Maryland. 



in sculpturing much like var. h. 



d. Diam. maj. 24, min. 20, Alt. 7 mill. Hah. Georgia. 



regularly striated — last whorl with microscopic spiral lines 

 on the upper surface. 



e. Diam. maj. 26, min. 22, Alt. 9 mill. Hah. Middle Georgia. 



very finely striated — microscopic elevated points in spiral 

 lines on the upper and under surface of the last whorl — 

 shell very thin ; umbilicus larger than in other forms, and 

 aperture more rounded ; the entire shell of the same color, 

 — in the other varieties the base is of lighter color than 

 the upper surface. This is allied in form to H. fuliginosa 

 Griff. 

 /. Diam. maj. 13, min. 20, Alt. 7 mill. Hah. Georgia. 



striae above like var. d, but they are continued over the 

 periphery to the umbilical excavation. 

 g. Diam. maj. 23, min. 20, Alt. 9 mill. Hah. St. Augustine, Florida. 



shell polished, sculpturing like var. 6, the color of the upper
