forms of the genus Niso, but are distinguishable from them by the absence of the large 

 open umbilicus. They also approach some forms of the genus Eulima, but, unlike that 

 genus, the labium (or left lip) is extended over the umbilicus. 



Feeling the impropriety of keeping these shells in the genus Paludestrina, and pressed 

 by the difficulty of finding a genus suitable to their reception, I propose the above name 

 Eulimene (one of the Nereids) for their reception.

Eig 21, a, b, Supplement Tab. IV, represents a specimen lately found by myself in the 

 Cor. Crag of Sutton, which, from its imperfect state, I do not feel justified in referring to 

 any particular name. The presence, however, of an open umbilicus shown in the figure, 

 coupled, with its tapering form, suggests some affinity with the genus Niso.

A single specimen shown in the above figure has been found by me at Sutton, which, 

 I think, may be referred to -this species. The artist has not been very successful in its 

 representation.
