EULIMA. 237 



M'Andrew, from a sandy bottom of eighty-two fathoms, 

 thirty miles from the east coast of Zetland, 



We have examined the animal alive in Mediterranean 

 specimens. It has the*usual elongated foot and subulate 

 tentacles of its congeners, but has the lateral lobes much 

 more largely developed, and somewhat obliquely placed. 

 The operculum is unsymmetrically pyriform, corneous, 

 thin, and has a slight involution, as if an eifort towards 

 the formation of a spire at its rounded extremity. 



This shell is distributed sparingly along the southern 

 and western shores of Great Britain, and around Ireland, 

 extending from Cornwall and Cork to Zetland, and inhabit- 

 ing in depth from ten to eighty fathoms. Mr. Bean states 

 that it occurs, though rarely, at Scarborough. 



It extends its range to the Mediterranean, and dates 

 backwards in time to the coralline crag epoch. 



E. BiLiNEATA, Alder. 



Narrowly subulate, whitish, with two adjacent reddish yellow 

 lines encircling the lower half of the upper whorls, and the 

 middle of the final one.

It is with some hesitation that we adopt this shell as a 

 species, and rather in accordance with our principle of never 

 degrading a species from the rank it has once been ele- 

 vated to, without palpable proof of its being a mere variety,
