390 PLIOCENE MOLLUSCA. 



excessively fine and closely-set spiral striae, hardly visible except under the 

 microscope, but without longitudinal sculpture; suture oblique, well-marked; 

 mouth short, wide, oval, angulate above ; outer lip inflected, thickened, much 

 expanded ; inner lip forming a thin, narrow glaze upon the columella; canal wide, 

 very short, open. 



Dimensions. — L. 5 mm. B. 2 nun. 



Distribution. Not known living. 

 Fossil: St. Erth. 



Remarks. — This St. Erth fossil is another specimen from the British Museum, 

 and was described in 1898 by A. Bell as then unknown except from the above 

 most interesting deposit. Neither the latter nor I have been able to find anything 

 in the works accessible to us or in the collections we have examined that 

 approaches it.

Specific Characters. — Shell minute, fairly solid, elongato-turreted ; whorls but 

 slightly convex, the last about two-thirds the total length, regularly diminishing 

 in size to a blunt point; ornamented by numerous longitudinal costae, clathrated 

 by strong spiral striae and granulated when they intersect ; suture distinct ; mouth 

 short, oval ; outer lip expanded, thickened, grooved within ; inner lip slight; canal 

 very short. 



Dime7isions. — L. 6'5 mm. B. 3 mm. 



Distribution. — Recent: coasts of Provence, Corsica, Sardinia, Naples, Palermo. 

 Ionian Sea, Gallipoli. Porcupine Expedition — Adventure Bank. 

 Fossil : Selsey. 



Remarks. — The specimen here figured was found by Mr. A. Bell many years 

 ago at Selsey and is now in the British Museum (Nat. Hist.). 



It was at first referred by him to D. mini ma, but more recently to the present 

 species. I think with him that it is not D. minima. The descriptions of D. lineo- 

 lata given by various authorities do not altogether agree. Tiberi says, for 

 example, that the sculpture is not granulate ; Locard says it is. Our St. Erth 

 fossil appears to correspond more nearly with 7). lineolata than with anything else 

 I can find, and I therefore retain the name adopted for it by Mr, Bell. It is said
