accurately with the typical Pjiiglish 8. follacea , nor do those which he identifies 

 with 8. soptemcostata of Conti. M. de Boury reported S. foliacea from Asti, l)ut 

 with hesitation, and the Marquis de Gregorio a multicostate variety of that species 

 from Pisa. On the whole, I am compelled to doubt whether the true 8. foliacea 

 of the Crag occurs in Italy. In any case Sowerby's name stands good for the 

 English fossil. 



In a letter recently received from him, M. de Boury proposed the ucw sub- 

 generic name Nohiliscala for this and some allied species.

8pecific Characters. — Shell small, solid, conical, turreted; spire pyramidal; 

 whorls convex, disjoined, the last two-fifths the total length ; ornamented b}'' 9 

 longitudinal costae, slightly oblique, joined at the suture so as to be continuous 

 from base to summit ; mouth oval. 



Dimensions. — L. 10 — 24 mm. B. 5 — 11 mm. 



Distribution. — Not known living. 



Fossil : Selsey. Scaldisien : Belgium. Italy — Monte Mario. 



Bemarhs. — The fossil here figured was found many years ago at Selsey and 

 belongs to the York Museum. A photograph of it was submitted to M. de 

 Boury and identified by him with Prof. Sacco's var. belgica of 8. foliacea. In its 

 general appearance it corresponds very closely with the one represented by M. 

 Cossmann as Clathrus belgicus, though it is smaller and possibly immature, but not 

 so nearly with Nyst's figure of the Belgian shell from which it takes its name. 

 At first considered by M. Cossmann to belong to Clathrus, it has been more recently 

 referred by M. de Boury to a new sub-genus, Nobillscala. Signor Cerulli-Irelli 

 reports it from the Upper Pliocene of Monte Mario, but it is unknown from the 

 English Pliocene.
