BELA BICARINATA. 393 



fig. 12). It is specially interesting as, except for the specimen from Aldeby, this 

 species has not been recorded hitherto from any British deposit. 



I have also identified the following species of Beta, from Wexford, viz. : 



B. scalaris, Moller. B. Trevelyana, Turton. B. turricula, Montagu. 



//. nohilis, Moller. B. rugulata, var. Trevelyana, scalaroides, CI. 0. Sars. 



//. pyramidalis, Strom, var. laeviuscula. — It may be interesting to notice, however, 

 that of these B. turricula, a species characteristic of the later part of the Crag 

 and of the British Pleistocene, is the most common.

Distribution. — Fossil: (additional) Iceland Crag — Husavik. Bridlington. 



Remarks. — In PI. XXXII, fig. 27, of the present work I figured a recent 

 specimen of this species for the guidance of collectors, as the one found by 

 Mr. A. Bell at Butley could not be traced. Since then I have received a fossil 

 from Mr. Headley, obtained from the Bridlington drift, which corresponds with 

 that already given. Some difference of opinion exists as to the correct nomen- 

 clature of this little shell. Dr. Odhner, accepting the specific term bicarinata, 

 identifies it with B. violacea, while Jeffreys regarded the latter as a variety of 

 the former. Most authorities, however, have preferred to regard the two forms 

 as specifically distinct. 



B. bicarinata was recognised by Jeffreys in 1885 among some fossils from the 

 Pliocene deposits of Iceland which were submitted to him by Mr. J. Starkie 

 ■Gardner (op. cit.).
