HELICINA. 



355 



scopic, punctured lines. Spire elevated, wliorls five, 

 moderately convex, tlie 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 mqre convex, and the lip notched at 

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

 collections. — [g.]
