Fig. I. Valvatella Bermgensis, n.sp. 

 ,, II. albolineata, n.sp. 



This species is closely allied to V. helicina (Fabr.), from Northern 

 seas, and, indeed, might be regarded as a large variety of it. It is, 

 however, very much larger, more solid, with a thicker superficial 

 layer of carbonate of lime and more distinct lines of growth. The 

 white and more thickened columellar margin is another distinguishing 

 feature, the aperture is larger and more patulate, the lower surface 

 of the body-whorl has ouly the faintest indication of concentric striae, 

 and the umbilicus is slightly more contracted.
