Not common. Laminarian, sometimes Littoral. I have found it 

 alive several times, but have not seen it extended. The operculum 

 is dark brown, ovate, strongly marked by concentric lines of growth; 

 lingual ribbon long, narrow. Teeth 1-1-1; lateral teeth simple, 

 curved; median tooth with three stout denticles and smaller ones 

 each side.

Occurs rarely alive, but dead shells are not very uncommon on 

 the beach. A long, slender variety, with eight whorls, is sometimes 

 found. The Messrs. Adams refer this shell to Amycla, as I think, 

 wrongly.

Often found alive under stones, and on sea weeds at extreme low 

 water, and dead in sand on the shore.

Occurs rarely with the preceding^ of which it is probably only a 

 variety.

I discovered three fine specimens of this Northern species in a lot 

 of Amycla lunata.
