The most important discovery is that of the well-marked 

 species Terabratula Mbrierei, which has hitherto only been found 

 in France. It was first described and figured by Mr. Davidson in 

 the Annals of Natural History for 1852, vol. ix. (second series), 

 p. 256, pi. xiv., fig. 3 and a, b, the M.S. name of Terebratula 

 Morierei having been given to it by Deslongchamps after its 

 discoverer M. Moriere. It was afterwards described and figured 

 by E. Deslongchamps in 1857, " Catalogue descriptif des 

 Brachiopodes du systeme Oolitique Inferieur du Calvados," p. 

 37, pi. iv., fig. 6, a, J; and in 1837, in the Paleontologie Fran- 

 <;aise Terrain Jurrassique, Brachiopodes, p. 244, pi. Ixv., figs. 

 1-8. It is a very rare species, having been found in France 

 in only one locality, Ste. Honorine desPerthes (Calvados), in the 

 white Oolite of Port-en-Bessin, which contain Terebratula 

 Phillipsii, Morris, and Rhynchonella plicatella. Sow. ; these species 

 occur with it in England. 



There appears to have been some doubt whether in France this 

 species had been found in position, or in a loose block which 

 might have fallen from the Great Oolite above. M. Deslong- 

 champs regarded it as an Inferior Oolite fossil, but the finding 

 of this species settles the questions with regard to its age, as no 

 Great Oolite occurs in the quarry from which I obtained this 

 specimen. 



Whilst examining the well-known quarry at Bradford Abbas, 

 on the farm of Prof. Buckman, I picked up this specimen from 

 the horizon of Rhynchonella parvula, E. Desl., but did not recog- 

 nise it until I commenced to clean it; it corresponds in all 

 respects with the figured specimens, showing the deep sinus in 

 both valves and peculiar concentric projecting imbricated ridges 

 which well distinguish this species. It belongs to a small group, 

 of which it is the earliest representative, followed, in the Fuller's 

 Earth rock, by Terebratula reticulata and the closely-allied or 

 identical species Terebratula hybrida, and in the Great Oolite by 

 Terebratula coarctata. The specimen is about the size of figure 7 

 in pi. 65, Pal. FranQ. Brachiopodes Jurassique. It is well pre- 

 served, both valves being perfect. I also obtained from the
