564 PLIOCENE MOLLUSCA. 



Var. grossa, Mai-shall. Plate XLIX, fig. 15. 



1894 — 1900. Odostomia pusUla, var. grossa, Marshall, Jouru. of Conch., vol. vii, p. 384, 1894 ; 

 vol. ix, p. 334, 1900. 



Varietal Characters. — Less cylindrical, shorter and broader than the tj'pe, with 

 somewhat coarser sculpture. 



Dimensions. — L. 4 mm. B. 1 mm. 



Distrityvtion. — Recent: Stornoway, Loch Inver, Gairloch, Torbay. 

 Fossil : Selsey. 



Bemarl-s. — M. Dautzenberg has lieen kind enough to identify the specimen 

 figured under this name, which was found at Selsey and belongs to the York 

 Museum, with Marshall's var. (jrossa. The author says that it might easily be 

 taken for 0. lacfea, but it is never conical like that species, the lower whorls being 

 of the same width and rounder at the base. He considers that it is the same as the 

 var. sinuosa of Jeffreys.^ but that the specimen of the latter was not quite mature. 



Turbonilla recta (Etheridge and Bell). Plate XLIX, fig. 10. 



1898. Chemmtzia recta, A. Bell, Trans. Hoy. Geol. Soc. Cornwall, vol. xii, p. 147. 



Specific Characters. — Shell small, allied to T. ohliqna, but having straighter 

 costae, somewhat more compressed whorls and a slightly shallower suture. 



Dimensions. — L. 6 mm. B. 2 mm. (when complete). 



DistribnfioH. — Not recorded living. 

 Fossil : St. Erth. 



Remarks. — The imperfect specimen figured under this name is one of several 

 small TnrhonilJce. from St. Erth in the British Museum, which were regarded as 

 new by Messrs. Etheridge and Bell. A similar shell in the Warburton Collection 

 was identified doubtfully by them with the Turbo gracilis of Brocchi, but it 

 seems to me that the figure of this species given by the latter author has but 

 slight resemblance to our fossil. 



Turbonilla expallida, sp. nov. Plate XLIX, fig. 19. 



Specific Characters. — Shell of medium size, subcylindrical, turreted ; wdiorls 

 slightly convex, gradually but regularly increasing ; ornamented by rather strong 

 sinuous costce as wide as the interspaces, hardly reaching the base ; spire elongate, 

 subcylindrical; suture well-marked, slightly channelled but not deep; mouth short, 

 compressed, angulate and narrowed above, rounded and expanded below. 



Dimensions. — L. 10 mm. B. 2*5 mm.
