10 NEW SPECIES OF FOSSIL SHELLS FllOM TABLE CAPE, 



very broadly shouldered. Aperture large; columella very 

 convex above, excavate below, where it bears four rather 

 thin plications, of which the anterior is almost vertical, the 

 others being more transverse. Outer lip very rounded in 

 outline much thickened, slightly corrugated within. 



Long. 5, lat. 3.3 mill. 



Table Cape, 2 examples. 



Related to the last, but is a much broader shell, of differ- 

 ent appearance, and lacks the strong toothing on the lip. 

 PL IV., fig. 2. 



MargineUa subquinquidens, Sp. nov. 



Shell smooth, shining, broadly fusiform, with a prom- 

 inent blunt topped spire. Whorls four, rounded; not shoul- 

 dered above the aperture. Aperture rather narrow, widen- 

 ing towards the front. Columella nearly straight, bearing 

 five plaits, which are massive and broad, and practically all 

 on the same slant. The fourth plait varies in different in- 

 dividuals, from being nearly as strong as the others, to less 

 and less prominence, until in some specimens it is absent; 

 hence the name. Outer lip rather rounded, strongly thicken- 

 ed, smooth within. 



Long. 5, lat. 3 mill. 



Common at Table Cape. 



PI. IV., fig. 3. 



MargineUa rotunda, Sp. nov. 



Shell very small, roundly pyriform, spire scarcely exsert- 

 ed. Aperture about as high as the shell, curved, narrow 

 above, but widening towards the front, which is somewhat 

 produced. Columella very roundly convex, with three mod- 

 erate-sized teeth, and two or three minute denticles above. 

 Outer lip moderately thickened, unarmed. 



Long. 2.5, lat. 2 mill. 



Table Cape, 3 specimens. 



This may resemble in form M. octoplicata, Ten.-Woods, 

 of which he gives no measurements, but it is separated from 

 that species by its smooth outer lip. 



PL IV., fig. 4. 



MargineUa altispira, Sp. nov. 

 Shell broadly fusiform, with a tall, blunt-topped spire. 

 Whorls four, moderately rounded; the spire and aperture are
