3. EcHiNOCTAMus KUMMULiTicus, var. oviFOEMis. Plate XXV, Figs. 25-28. 



The marginal outline of this variety is oval, and the test is regularly convex both 

 on the abactinal and actinal surfaces, resembling the shape of Fibularia very closely. 

 The sides are very tumid, there is no flattening of the actinal surface, and the test is 

 very faintly impressed round the peristome.

4. EcHiNOCYAMUs NUMMULiTicus, var. PLANUS. Plate XXV, Figs. 29-32. 



The test is low and depressed, elongate and pentagonal, and the abactinal surface is 

 very slightly convex. The actinal surface is more or less plane, but well rounded on to the 

 sides, and there is a subrostral prominence anteriorly, and a slight concavity of the whole 

 surface occurs, running transversely through the peristome. Length of test 7'5 millim.

5. EcHUsOCYAMUs KOTUNDUS, Buncan & Sladen. Plate XXV, Figs. 33-37. 



There is a solitary specimen which we are unable to refer to any previously known 

 form of Echinocyamus ; and although it is difiicult to make out some of the details of
