62 LlTTORINIDiE. 



rather broad snout, aud long subulate tentacles bearing 

 conspicuous black eyes on the outsides of their thickened 

 bases. The foot is rather short, rounded at both ends, 

 and contracted in the middle, so as often to assume an 

 hour-glass shape. It is grooved medially below. The 

 operculigerous lobe, though large, is not developed to the 

 same extent as in the neighbouring British species ; but 

 appears like a ledge on each side of the pale yellow 

 operculum, and has the two caudal filaments reduced to 

 points or almost obsolete. 



This pretty and variable shell is very generally dis- 

 tributed all round our shores, though perhaps not quite so 

 plentiful as vincta. Like it, it inhabits the Lamiuarian 

 region. Abroad, it ranges from the shores of Norway 

 (Loven), to as for south as Vigo Bay in Spain (M 'An- 

 drew). 



L. viNCTA, Montagu. 



More or less oval-conoid, the length invariably exceeding the 

 breadth ; spire more or less raised ; canal very distinct.
