posteriorly. The dorsal valve is strongly biplicated with a 

 deepish median sinus, and two lateral ones. This species has 

 sometimes attained three inches and eight lines in length, by 

 two inches and ten lines in breadth. Some examples are shorter 

 and broader than others. It occurs in the same localities with 

 T. Stephani, and is not a rare fossil at Bradford Abbas.

TEBEBBATTJLA FEBBYI, E. Desl. Brachiopodes Jtirassiqucs, pi. xcvi., 



1874. 



Shell somewhat sub-pentagonal, longer than wide, valves 

 almost equally convex. Dorsal valve strongly and sharply 

 biplicated at its anterior half, a deep angular sulcus existing 

 between the two projecting folds. Ventral valve with a deep, 

 central, angular rib and sulcus on either side ; beak tapering, 

 incurved, and truncated by a circular foramen, separated from 

 the hinge-line by a narrow deltidium in two pieces. In size this 

 shell does not seem to have much exceeded 12 or 14 lines in 

 length by about 10 in width. It occurs at Bradford Abbas, 

 Half-way House, and in one or two other places. 



No. 5. TEREBRATTJLA GLOBATA, Sow. Plate II., fig. 7. 



TEBIBEATULA GXOBATA, Sow. Min. Con., pi. 436, fig. 1, 1823. 



Sub-globose and sub-pentagonal, longer than wide, moder- 

 ately biplicated near the frontal margin, fold not extending to 

 any considerable length, so that the larger portion of the valves 

 are uniformly convex. Beak rounded, incurved, and truncated 

 at its extremity by a small circular foramen. At Bradford 

 Abbas the shell does not appear to have much exceeded an inch 

 in length, by ten lines in breadth. It is not so abundant as 

 T. Eudesei, a closely-allied species. 



No. 6. TEREBRATULA EUDESEI, Oppel. Plate III., fig. 4. 



TEEEBEATULA EUDESEI, Oppcl. Die Jtira Formation, p. 428, 1856 



This is a common shell in the Bradford Abbas district, where 

 it has sometimes attained one inch three lines in length by one
