394 PLIOCENE MOLLUSCA. 



rather blunt apex ; ornamented by prominent flexuous costae, crossing the shelf 

 obliquely and reaching the suture, and by -well-marked spiral ridges ; suture deep » 

 mouth considerably less than half the total length ; outer lip rounded, slightly 

 expanded ; canal short, wide and open. 



Dimensions. — L. 15 mm. B. 6 mm. 



Distribution. — Recent : Norwegian coast from the Christiania fiord to Finmark, 

 Lofoten Islands, Iceland, Greenland, Spitzbergen. 

 Fossil : Bridlington. 



Remarks. — This northern species was included by Jeffreys in his list of 

 Bridlington fossils, and has been recorded also by Mr. Alfred Bell from that locality. 

 The latter, when recently examining Mr. Headley's collection, was fortunate enough 

 to discover Jeffreys' original specimen, unfortunately not quite perfect, with the 

 name in the well-known writing of the latter on the box. This Mr. Headley has 

 been kind enough to allow me to figure.

1914. Bela multistriata, F. W. Harmer, Plioe. Moll. Gt. Brit., pt. ii, p. 288, pi. xxxii, fig. 29. 



Remarks. — The specimen here figured, also from Mr. Headley's collection of 

 Bridlington fossils, is rather more characteristic than the one given on my 

 PI. XXXII, showing the distinguishing angulation of the whorls more clearly.

Distribution. — Fossil: Wexford gravels ; Leda myalis-bed Runton (additional). 



Remarks. — A single specimen of this widely-spread British and northern 

 species has been obtained from the Wexford gravels. Although apparently full 

 grown it measures only 9 mm. in length. It is a common Pleistocene shell 

 occurring less frequently in the Crag and more generally at the newer horizons.
