590 PLIOCENE MOJ.LUSCA. 



has informed me belongs to tlie present species. 7?, hUineata was formerly 

 considered a variety of the former, which it nearly resembles, but it is 

 more solid and not (|uite so slender. Jeffreys remarks that it bears a miniature 

 resemblance to E. snhiihiia. The Marchese di Monterosato regards it as belonging 

 to a new and distinct group, SnJndttria. Prof. Seguenza has reported it as fossil 

 from two or three Pleistocene and Pliocene localities in Sicily and Calabria and 

 Prof. Br^gger from the post-glacial '/Wyx.s'-banks of the Christiania fiord. 



In the fourth volume of his British Conchology, p. 209, Jeffreys gives an opinion 

 that the specimens figured by Wood and by Nyst as E. siihiihit(< are not Donovan's 

 shell, but are in all probabihty the E. bilivcnta of Alder, adding that in their 

 opinion all reported from northern localities should be referred to the latter. 

 This view seems supported l)y the fact that Prof. G. O. Sars gives E. blliiieata 

 as a Noi'wegian species but not /'/. siihiiltifa. 



On the other hand Prof. Sacco figures fifteen widely different and named 

 varieties of E. {SiiJ)iiln)'it() siihiilafd from the Italian Pliocene, which show at least 

 that it is a very vai'iiible form. 



Eulima minima, sp. nov. Plate L, fig. 13. 



f>prclj]r (lliaraders. — Shell minute, slender, smooth ; whorls 5 — 6, flattened, the 

 last about half the total length, regularly increasing; sj)ire elongate, ending in an 

 acute point, suture slight; mouth small, acutely angulate above, rounded below. 



Diwenmms. — L. 2 mm. B. 1 mm. 



Disfnhnfiov. — Not recorded living. 

 Fossil : St. Erth. 



Tlrninrls. — The minute specimen here given belongs to the Wood Collection of 

 St. Erth shells in the British Museum, where it has been labelled E. Stalioi. It 

 differs materially, however, from the figures of that species which have been 

 represented in the text-books, nor can I find anything else to which it can be 

 satisfactorily referred. I describe it provisionally therefore as new. 



Eulima subuliformis, A. Bell, MS. Plate L, fig. 14. 



Specific Gharaciers. — Shell slender, subulate, smooth and polished; whorls 

 flat, the last more than half the total length, obtusely but slightly keeled at 

 the periphery; spire elongated; suture slight; mouth long, slender, acutely 

 angulate above. 



Dhneusions. — L. 8 mm. B. 1'75 mm. 



Distribution. — Not known living. 

 Fossil : St. Erth.
