DRILLIA EMENDATA. 227 



Miocene : North Germany, Vienna basin, Italy. Lower Pliocene : Italy — 

 Castelnuovo d'Asti, Ligurian coast. Pleistocene : Italy — Reggio, Valle Biaia ; 

 Sicily — Ficarazzi. 



Uemarlcs. — I have a fossil from Oakley which, though rather worn, is perfect, 

 and corresponds in form with some specimens of D. crispata in my collection from 

 the argiles hleues of the Ligurian coast, one of which I have 'figured for comparison 

 with it. This species is a characteristic, though not a very abundant, form of the 

 Middle and Upper Miocene of northern Italy, occurring also in the Piacenziano of 

 Piedmont and Liguria. Prof. Sacco records it doubtfully from the Astian deposits. 



The shell from the Coralline Crag, figured by Wood as Plenvotoma crisjxita, 

 var. papulosa (Mon. Crag Moll., 1st SuppL, p. 35, pi. vi, fig. 13), is, I think, of 

 another species. I have described it in the present Memoir as Oligofoma festiva 

 (see p. 216). Reeve's Pleurotoma crispata (Conch. Icon., vol. i, Pleurotomidse, 

 pi. xix, fig. 156) is also a different shell.

Specific Characters. — Shell minute, fusiform, turreted; whorls 7, but slightly 

 convex ; the upper ones ornamented by three raised spiral ridges, the middle one 

 being the most prominent, the upper part of the whorls by the oblique lines of 

 growth ; body-whorl multicingulate ; suture distinct ; mouth oblong ; canal short. 



Dimensions. — L. 9 mm. B. 4 mm. 



Distribution. — Recent: Mediterranean, Adriatic, West European. 



Fossil : Coralline Crag : Gedgrave, Sutton. Upper Pliocene : 

 Sicily — Altavilla. Pleistocene : Ficarazzi, Monte Pellegrino, Castroreale. 



Remarks. — There is a fragmentary specimen from the Coralline Crag of Sutton 

 in the Wood Collection at the Norwich Museum labelled in his own writing 

 Fleurotoma Renieri, which corresponds, so far as it goes, with one from the 

 Pleistocene deposit of Ficarazzi near Palermo, kindly sent me by the Marchese di 

 jMonterosato, which I have figured.
