570 PLIOCENE MOLLUSCA. 



Distribution. — Recent : Oxwich Bay near Swansea. Shellness, Kent. Bantry 

 Bay. 



Fossil ; Selsey. 



Remarks. — Mr. Bell reports an imperfect fossil specimen of this rare shell which 

 he found many years ago at Selsey, remarking that so far as it goes its sculpture 

 closely resembles the recent one figured by Forbes and Hanley. It had been 

 previously obtained from several British localities by G, B. Sowerby, Jeffreys and 

 McAndrew. The Selsey fossil is now in the York Museum.

Specific Characters. — Shell slender, subulate; whorls 10 — 12, flattened; orna- 

 mented by inconspicuous costas, sometimes obsolete, and by fine spiral thread-like 

 lines, closely duplicate, extending to the base ; spire elongate, regularly tapering to 

 a sharp point ; suture slightly channelled, well-marked but not deep ; mouth oval, 

 angulate above, longer than in T. filosa. 



Dimensions. — L. 8 mm. B. 2 mm. 



Distribution. — Not known living. 



Fossil : Coralline Crag : Sutton. 



Remarlis. — As stated on p. 569, this form is closely allied to T. filosa, but in 

 the specimen here figured the spiral lines are closely duplicate, a feature which my 

 artist has failed to show, but which is visible under the microscope. Wood states 

 that in an example in his collection the longitudinal costse are absent, the spiral 

 markings only being shown. I have found a similar one myself (var. ecostata, 

 fig. 31), also at Sutton.
