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 would 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.

 producto, in medio subangulato. 



Hab. Mino-Sima J 63 fathoms. 



2. Eulimella opalina, A. Adams.

 opalina; anfractibus 10, planatis; suturis distinctis ; anfractu 

 ultimo lato, ad peripheriam obtuse angulato ; apertura oblonga, 

 lata, antice producta ; labio rectiusculo ; labro in medio producto
