quoted from Louisiana, catalogued by Adams from Jamaica, and 

 placed by Poey in the synonymy of L. cubensis, Pfr. 



No. 8429 of the collection has Prof. Adams's label " L. uinhili- 

 cata.''^ I follow Haldeman and Kiister in considering it a syno- 

 nym of L. caperata, giving below a copy of Adams's figure and 

 description. 



Limnxa umhiUcata. — Shell rather strong, brown, ovate, with slight striae 

 of growth, and more slight, numerous, irregular, revolving, impressed 

 lines; whirls five, convex; suture deeply {repressed; spire two-fifths of 

 the length of the shell, conic, subacute at the apex, angle of its 

 opposite sides about 65>2 ; body whirl inflated, subglobular ; 

 aperture ovate, its plane, also the line of its length at angles 

 of about 150 with the axis of the shell, three-fifths as long as 

 the shell ; labrum thin, inner margin dark-brown, inner sub- 

 margin thickened with a light pink deposit ; columella strong, 

 reflected and spread over an umbilicus, which is rather large, 

 but not profound, and formed chiefly by the reflection of the 

 columella ; fold of the latter inconspicuous. Length .28, breadth .17 inch. 

 Cabinets of the Boston Soc. Nat. Hist., of Middlebury College, of Mr. 

 Shiverick, and my own. New Bedford. 



For this species lam indebted to Mr. Shiverick, who obtained numerous 

 specimens. It resembles L. cnperatus, Say, but in Say's species the aper- 

 ture is but one-half the length, the revolving lines are raised, more dis- 

 tinct and numerous, the umbilicus is rather less, and there is one more 

 whirl. (^Adajns.)
