86 PLIOCENE MOLLUSCA, 



Miocene : Touraine. 



Bemarlcs. — S. V. Wood speaks of having obtained two examples of N. granifera 

 (a shell which MM. Dollfus and Dautzenberg now identify with i?»ccw»mf?M'one?ise, 

 Deshayes) from the Coralline Crag of Sutton, and another from the Ked Crag of the 

 same locality. Mr. A. Bell found it also at St. Erth. 



The form is fairly common, however, at Oakley, some of the specimens being- 

 unworn. ♦ 



Its occurrence at that place is interesting as its comparative abundance 

 negatives the view that it is derivative : the frequent presence of this and other 

 characteristic Miocene species at the Waltonian stage, tends to support the view 

 I have taken that this, the oldest known horizon of the Red Crag, is more closely 

 connected with the Coralline Crag which preceded it than has hitherto been 

 supposed. My specimens correspond with Wood's figure, but they are not so 

 tumid. In form and in other respects they agree with some I collected in Touraine, 

 except that the Crag shells are generally more distinctly granulate ; the latter may 

 perhaps be regarded as a variety of the Miocene species. That they should differ 

 somewhat from it need hardly surprise us when we remember that they lived in 

 different areas and at periods widely separated.

Specific Characters. — Shell small, ovato-conical ; apex obtuse ; whorls G, slightly 

 convex ; suture subcanaliculate ; ornamented by exceedingly fine, equidistant 

 spiral strige, extending to the base of the shell ; mouth ovate, acutely angulate 

 above ; outer lip thickened, plicated Avithin ; inner lip forming a glaze which is 

 spread over the pillar; canal short, open, notched, 



Bimensions. — L. 10 mm. B. 6 mm. 



Distribution. — Recent : Mediterranean. 



Fussil : Waltonian Crag : Walton, Little Oakley. Newbournian : 

 Bentley. Sicilian Pleistocene : Ficarazzi, near Palermo and elsewhere. 



Remarks. — I have obtained two specimens of this shell from Oakley, one 

 immature, the other full grown.^ They appear to correspond with some fossil 

 shells from Sicily received from the Marchese di Monterosato, one of which is here 

 figured, together with another, also immature, found at Bentley by JNIr. P. G. H. 

 Boswell, F.G.S. 



^ The full-growu specimen, which showed the spiral markings distinctly, has unfortunately been 

 lost.
