GENOTIA RAMOSA. 211 



Miocene : Belgium, North Germany, Vienna l)asin. Lower Pliocene : Italy. 

 Upper Pliocene : Italy — Bologna, Livorna ; Sicily — Altavilla. 



Remarks. — This species is now grouped with the genus Glavatnhi of Lamarck, 

 distinguished by a long spire, and a rather short canal, the outer lip having a 

 marginal notch below its junction with the body-whorl. 



An imperfect specimen from the Newbournian Crag of Waldringfield was 

 referred by Wood to this species, which is very common, according to M. van den 

 Broeck, in the Miocene (Bolderien) of Belgium (zone a Panopsea Menardi) and is 

 characteristic of the Pliocene deposits of Italy. 



It is the only representative of the present genus hitherto recorded from the 

 East Anglian Crag, but it is probably derivative in our deposits.

Specific Characters. — Shell subfusiform, elongate, turreted ; spire tapering to 

 an acute point ; whorls noduloso-carinate, keel situated not far below the suture : 

 the nodules pass downwards into inconspicuous longitudinal ribs along the lines of 

 growth, two of the latter becoming confluent on each nodule ; covered b}^ fine and 

 closely-set spiral stri« which cross the ribs ; body-whorl two-thirds and mouth 

 one-half the total length ; mouth long and narrow, angulated above by the keel 

 of the last whorl, which is continuous with a straight and open canal. 



Dimensions. — L. 25—70 mm. B. 8 — 28 mm. 



Distribution. — Not known living. 



Fossil : Waltonian Crag : Little Oakley. 



Miocene : Belgium (Nyst), North Germany (von Koenen), 

 Touraine, Vienna basin, Italy. 



Remarls. — The genus Genotia, originally GenoUi, and formerly included with 

 Fleurotoma, was proposed ])y H. and A. Adams for a distinct group of shells, 

 conical or mitrffiform in shape, with a body-whorl diminishing regularly in size to 

 the base of the shell, and a long, narrow mouth continuous with the canal.
