Genus Eulimella, Forbes. 



From the figure in the ' British Mollusca ' of Eulimella Scillce 

 (pi. F. F. fig. 7), the animal has very obtuse folded tentacles and 

 other characters which vi^ould refer the genus to Pyramidellidse ; 

 the shell, however, is very similar to that of Eulima. The spe- 

 cimens serving for the descriptions of the following species were 

 dredged from deep water, and although in a good state of pre- 

 servation, were possessed of neither animals nor opercula.
