HELICINA. 



355 



scopic, punctured lines. Spire elevated, whorls five, 

 moderately convex, the last one somewhat flattened at 

 base and indistinctly angular at the periphery. Aper- 

 ture large, very oblique, semi-oval, the diameters about 

 equal ; the lip broadly everted, especially at its middle 

 portion, narrow and simple at its columellar junction, of 

 a golden-yellow color ; labial callus extended, of a deep 

 orange color. 



Axis one-third of an inch ; diameter two-fifths of an 

 inch. 



REMARKS. Of the history of this shell nothing is 

 known except that it was named by Dr. Binney, and fig- 

 ured by him with the other species. Hence it is to be 

 inferred that he had good authority for considering it a 

 native of the United States. It is not figured by Sowerby 

 in his Monograph of Helicina, unless it be under the name 

 of H. Jamaicensis , which it very much resembles. The 

 base seems to be more convex, and the lip notched at 

 base. It is a very pretty species, and must be rare in 

 collections. [G.]
