BARLEEIA CTNGULATA. 645 



EemarJis. — This shell, rather rare as a fossil, thou_o-h widely diffused as a recent 

 form, was recorded l)y Wood from the Coralline Crag of Sutton only. Abroad it 

 is given by Cerulli-lrclli from the Pliocene of Monte Mario, and by Seguenza from 

 the Pleistocene of Sicily. The s[)eciinen here given was obtained from Grarvel 

 Park. The generic term Gevatia was proposed by H. and A. Adams for a small 

 group of shells distinguished by certain anatomical characters, of which G. proxima 

 was taken as the type. The Marchesi de Monterosato states that these differences 

 separate it from all other forms of the Rissoidee. 



Genus BARLEEIA, Clarke, 1855. 

 Barleeia cingulata, A. Bell. Plate LI, fig. 47. 



1892. Barleeia chujulata, A. Bell, Rep. Yorks. Phil. Soc, p. 76, pi. i, fig. 17. 



Specific Characters. — Shell small, solid, conical ; whorls 6 — 7, flattened, smooth, 

 the last strongly angulated ; spire short, acute, with a blunt apex ; suture well 

 marked, slightly channelled ; mouth oval, angulated above, patulated below. 



Dimensions. — L. 4 mm. B. 1'5 mm. 



Distribution. — Not known living. 

 Fossil : Selsey. 



Beinarks. — 1 figure this Selsey specimen under the name given to it with some 

 doubt by Mr. A. Bell, who remarks that it differs from any species of Barleeia he 

 knows, though it is close to some of them, its chief characteristics being the flatness 

 of the whorls, the angulation of the last, and its patuliform mouth. The artist has 

 failed to show the angulated whorl in the Selsey paper, but Mr. Bell says this was 

 due to a mistake.
