CHEMNITZIA. 169 



III. EuLiMA. — The animals carrying these shiny, tapering 

 shells possess two long tentacula^ with eyes at their thick- 

 ened bases ; the foot is much extended in front, and square, 

 but short at the back, carrying a horny spiral operculum. 

 The shells have very acute apices, which are very apt to be 

 distorted, and oval or pyriform apertures. The British 

 species are — 



IE. polita: shell white, pyramidal. 



E. distorta: shell smaller, white, with a curved spire. 



E. suhnluta: shell narrow, coloured with brown spiral 



bands. 

 E. hilineata: rather fuller in form, white, with two spiral 



lines in the middle of each whorl. 

 A specimen of E. distorta, taken alive at Northumber- 

 land, had a yellow body with a variegated band of carmine 

 on each sid#. They live on sandy bottoms, at various 

 depths, rarely crawling out of their shells so far as to ex- 

 pose their eyes, the transparency of the shell rendering it 

 unnecessary. 



IV. Chemnitzia is a genus consisting of small molluscs,
