region. The anterior extremity of the test is considerably diL^ted, 

 and is a striking feature in the species. The type specimen in the 

 ]S"ational Collection is imperfect, and the characters above given have 

 been drawn np from the examination of a number of individuals.

The specimens in the jN'atural History IMuseum Collection are not 

 very well preserved, but agree with M. Deshayes' description and 

 figure. From the examination of a perfect specimen M. Cossmann 

 is able to state that it is ornamented by obsolete ribs, and is 

 furnished posteriorly with a short fissure. Kather rare. 



Formation. — Thanet Sands. Locality. — Heme Bay. 



Entaliopsis annulata, n.sp. PL VI. Fig. 1. 



Shell slightly arched, tapering gradually ; section circular ; surface 

 ornamented with numerous closely set annulations ; longitudinal striae 

 more or less obsolete ; fissure short and broad. 



Dimensions. — Length 12 ; diam. 2'5 mm. 



This species differs from others included in this genus by the 

 possession of delicate annulations. Annulations are more charac- 

 teristic of Fustiaria, but the great length of the fissure in the 

 latter prevents any misconception arising as to the generic deter- 

 mination of our species. Its fine annulations are somewhat analogous 

 in structure to those of Fustiaria suhehurnea, but are much more 

 closely set. The type specimen is in the best state of preservation, 

 although not the largest of the species ; an imperfect example from 

 Primrose Hill has a diameter of 3 mm., and exhibits the surface 

 ornamentation, both longitudinal and transverse, more than usually 

 distinct. Pare ; five specimens in the IS^ational Collection. 



Formation. — London Clay. Localities. — Portsmouth (type), South- 

 ampton, and Primrose Hill.
