Specific Characters. — Shell large, strong and solid, subfusifonn, more or less 

 elongate, bnt varying in the proportion between its length and its breadth; whorls 

 5 or 6, but slightly convex, compressed below the suture, smooth or but very finely 

 striated, the last much the largest, sometimes three-fourths the total length ; suture 

 slight; spire conical with a truncate and obtusely rounded apex; mouth oval, 

 acutely angulated above, passing into a short, rather wide and open canal ; outer 

 lip gently curved ; columella with 4 oblique and prominent plaits.

Remnrlis. — This fine shell is found everywhere in the Pliocene of the east of 

 England from Lenham to Butley and in that of Belgium, in fair abundance. It is 

 reported in Dr. S. P. Woodward's list from the Icenian of Norwich on the 

 authority of the late R. Wigham, but this has never been confirmed by any later 

 authority and may be regarded as doubtful. 



A closely allied shell is reported from the Miocene of Touraine under the name 

 of F. (Attlica) miocsenica by Messrs. Dollfus and Dautzenberg, and similar forms 

 are known from other Miocene deposits. Whether any of these should be regarded 

 as varieties of the Anglo-Belgian and Pliocene V. Lamherti or specifically distinct 

 from it, is a matter for continental rather than for English geologists. 



There are two distinct types of this shell in the Crag — one short and tumid, 

 about twice as long as broad, the other slender and three times as long.
