12 THE liUAClIIOrODA. 



zono of Opalinus to tlio zone of Parkinsoni. Tliis is certainly 

 e.vtrcmcli/ remarkable, since in the Avholo of this district I Jiavo 

 never found Tcrcb. Stcphani in ^\\y other zono than that of Cosra. 

 Parkinsoni, and I have always regarded it as peculiarly cliarac- 

 toristic of this zono. 



Torch. Stcphani boars some resemblance to I'ercl. Phillipsi and 

 Terch. infra-ooUthica. It is easily distinguished from the first 

 by its rounder shape and its beak, ■\Ahich slightly overlaps the 

 lesser valve, and from the second by its greater compurativo 

 length and deptli, and general shape. 



Dimensions. — Length 1 inch 10 lines, breadtli 1 inch 5 lines, 

 depth 1 inch. Another specimen length 1 inch 8 lines, breadth 

 1 inch 5 lines, depth 1 inch 3 lines. 



Localities. — A very abundant sheU at Bradford Abbas, Broad- 

 ■sviudsor, &c. (Dorset), and Crcwkerne Station, Stoford, and near 

 Galhampton, &:c. (Somerset), also Dundry (Somerset), according 

 to E. Deslougschamps, and at Bayeux, Sully (Calvados), at 

 Lavergne (Vienne), also in the whole of Burgundy, the neigh- 

 bourhood of Semur, &c., &:c. Also at Stuifemborg, Bopfingen, 

 Brauweberg, and Balingen (Wiirtomborg), at Liestal, Aarau 

 (Switzerland), and in Spain. 



4. — Terebhatula submaxillata, Morris. 



Terebratula submaxillata, Davidson, British Fossil Brach., 

 Palffiont. Soc, plate ix,, figs. 10-12. 



I possess one specimen from Bradford Abbas, -svliich in shapo 

 and general appearance agrees very well with specimens of T. 

 suhmaxillata from the Cotteswolds. It has, however, very small 

 sinuations. It agrees best with Mr. Davidson's figure 10 on 

 plate ix. of his Jurassic Brachiupoda. 



Localities. — Bradford Abbas (Dorset), also near Cheltenham 

 (Gloucestershire).
