I have only seen a single specimen, which was obtained for me 

 by Mr. Eeynolds, the fossil-collectoi', from Bradford Abbas. 



ASTARTE GLOBATA (nOBIS). FIG. 5. 



Shell sub-triangular, very tumid, so that its proportions are 

 nearly the same every way ; lunule broad, but not deep. Umbo 

 near the posterior margin. This is a small smooth delicate shell. 



Proportions : Length 8 lines, breadth 7, depth 6. 



This shell occurs very sparingly at Bradford Abbas. 



ASTARTE TUMID A (l^OBIs). FIG. 6. 



Shell sub-triangular, somewhat tumid, but less so than the 

 former. Umbo in the middle of the shell, forming the apex of 

 a nearly equilateral triangle, and thus differing from the 

 former. 



It is smaller than the former, but cannot be confounded with 

 it inasmuch as the A. tumida is rounder and only slightly gibbose. 



Proportions : Length, 6 lines ; breadth, 6 ; depth, 4. 



This shell is found rarely at Bradford Abbas, in bed 3 of the 

 section (marl bed). 



ASTARTE PULCHRA (nOBIS). FIG. 7. 



Shell somewhat triangular, the posterior margin is gibboso 

 but less so than A. tumida and more oblique ; uj^per margin 

 nearly straight ; lunule small and spoon shaped ; crenulations in 

 the interior of the shell very well defined. 



This is really a very distinct form, and cannot be confounded
