GASTROCOPTA, NORTH AMERICA, WEST INDIES. 83 



margins joined by a quite thick callous; parietal and colu- 

 mellar margins each having one lamelliform, deeply placed 

 and conspicuous tooth ; basal margin indistinctly two-toothed, 

 both in the depth of the aperture ; outer margin sometimes 

 provided with a tooth below the point of insertion, but this is 

 not constant. 



Length 2 1 /4, diam. % mm. (Crosse).

This species is evidently related very closely to G. pellu- 

 cida, having teeth in the typical positions, but it differs by 

 the narrower contour. I have not seen specimens. The name 

 longurio has been used by Moquin-Tandon for a variety of an 

 European species, but until specimens from Curasao can be 

 critically compared with pellucida, the desirability of a new 

 name need not trouble us.

 tooth. Length 2%, diam. % mm. (Pfr.).
