10 PLIOCENE MOLLUSCA. 



R. G-. Bell in the Butleyan Crag of Hollesley, where Mr. Kennard also has found it. 

 The specimen now figured is from the British Museum (Natural Histor}^) ; 

 attached to it is a tablet bearing a note in Mr. Bell's writing as follows : 



" This shell was taken out of a ]3it near the road occupied as a barn-varcl, 

 Page's farm, in corapan}" with marine shells and with Linmaea and Plaiiorhia."

Specific Characters. — See Mon. Crag Moll., pt. i, p. 2. 



Dimensions. — Diam. 8 mm. H. 5 mm. 



Distribntion. — Fecent : England, Wales, Ireland ; in Scotland as far as the 

 Caledonian Canal (J. AY. Taylor) ; abroad from Siberia and the Faroe Islands to 

 Sicily and Northern Africa; North America (introduced) ; Grand Canary (Farrer). 

 Fossil : Butleyan Crag : Butley. Icenian — Noricicli zone : 

 Bramerton, Thorpe near Norwich, Horstead, ^Coltishall, Dunwich, Bulchamp, 

 Yarn Hill. Weyhourne zone: East Runton, North Walsham boring (C. Reid) ; 

 Freshwater bed, West Runton. Pleistocene: Selsey (A. Bell), Woodston, near 

 Peterborough ; with many other localities in the British Isles. Holocene : Great 

 Britain (Kennard and B. B. Woodward). 



Pleistocene: Ymwce—Lmions gres a Siicciitecs, Normandy (Rutot), Toulouse; 

 Austria — Nussdorf, near Vienna; Germany — loess of Lower Rhineland, Mosbach ;

R&marhs. — This species was known to Wood from the Icenian Crag of 

 Bulchamp only. Mr. A. Bell, and ]\Iessrs. Kennard and B. B. Woodward have 

 reported it, however, from Butley and from many localities in the Icenian Crag. 

 The latter Avriters remark that it is the commonest helicoid species of our Pliocene 

 and Pleistocene deposits. On the Continent it has not been observed in any 

 earlier deposit than the Lower Pleistocene of Mosbach, where it is found not 

 infrequently.
