230 PLIOCENE MOLLUSCA. 



Pleurotoma Eenieri (Tarentinl), but it does not seem to me to correspond Avith the 

 type figures of either of them. It is no doubt the same as that described l^y 

 Wood under the latter name ; in that species, however, as shown in Philippi's 

 original drawing of P. Tafentiiii, the greatest transverse diameter is nearer the 

 base of the shell and the body- whorl is wider in proportion. 



D. Kendalli is a very charming as well as a very distinct shell, and I can find 

 nothing to which it can be satisfactorily referred.
