This animal is elongated, granulated above, grooved 

 along the right side, of a general yellowish, tawny, or 

 reddish hue, sometimes grey. The upper tentacles are rather 

 long, the head small, the body increasing in bulk poste- 

 riorly, the tail steep and abrupt, and the foot marginated. 



The shell, which is tolerably strong for its size (its length 

 rarely, if ever, exceeds the third of an inch), is of a subau- 

 riform shape, but ranges from rounded oval to subtrun- 

 cated oval ; it is flattened and covered with a brownish 

 ash -coloured epidermis nearly smooth, or at most, concen- 

 trically subrugose ; the vertex is acute, prominent, and 

 subspiral ; the pillar, which is very broadly dilated, and 

 somewhat twisted above, contracts rapidly below. The 

 aperture is bluish white, and decidedly broader above 

 than below ; its external margin at first slopes very slightly 

 outwards in a nearly straight line, and then forming a 

 rather obtuse angle, inclines inwards with a gentle arcua- 

 tion : the angle is very evidently below the level of the 

 vertex. 



This is peculiarly a southern species. It occurs in the 

 Channel Isles, where it was first noticed by Mr. Lukis. 

 Mr. Sowerby found it in a garden at Lambeth, and it has
