Shell about one inch long, and fourteen lints broad; of a grey- 

 ish white colour, with scattered brown spots, and besides the 

 elevated transverse ribs, it is strongly striated longitudinally, 

 which serves at once to distinguish this species from V . Dy- 

 sera ; the ribs are irregularly distant, and crenulated on one 

 side, aud the longitudinal stria generally in pairs ; the poste- 

 rior depression is heart-shaped, striated longitudinally, and 

 marked with transverse brown stripes ; the margin is thick, 

 and slightly crenulated : Meuschen, as well as Gronovius, 

 considered this to be the Linnaean V. cancellata, but it is 

 more probable, from his reference to Lister, t. 278. f. 115., 

 that Linnaeus confounded it with V. Dysera.
