so generally around our shores, that we need not enume- 

 rate localities. Occasionally specimens much distorted 

 are taken, apparently when an influx of fresh water has 

 effected their growth, and to sonic such cause, possibly 

 to the melting of icebergs, we may attribute the curious 

 monstrosities of this species which occur in the red 

 and mammaliferous crags, such as those figured by Mr. 

 Searles Wood in his excellent work on the Crag Mol- 

 lusca. It is found along the Atlantic shores of Europe, 

 ranging southwards as far as Asturias. 



L. EUDis, Donovan. 



Solid, rarely ridged ; whorls rounded, spire acute, more or less 

 short. Mouth small, more or less rounded, not contracted above, 

 but lessened at the base by the broad confluence of the pillar and 

 outer lip, which latter is rather more arched above than below, 

 and joins the body at nearly right angles. Base generally a little 

 produced.
