Ralph Tate — New Secondary Brachiopoda. 553 



B. variabilis (pars), Anctorum Anglicorum. 



This species can readily be distinguished from B. variahilis, 

 Schloth., with which it appears to have been confounded in this 

 country, by its numerous ribs, twenty-five or so in number. In Ger- 

 many, France, and Britain, it ranges throughout the Lower Lias ; and 

 is very abundant in the Bucldandi limestones in the West of Eng- 

 land, as at Horfield, Ashley, Keynsham, near Bristol ; Badgsworth, 

 Cheltenham (Tate); Evercreach, near Bruton (HoU). 



16. Ehynchonella oxynoti, Quenstedt sp. Handb. Petref, t. 36, 

 f. 4-5 (1852). Terebratula Maceana, D'Orbigny Pi'odr., p. 221 (1850). 

 BhyncJionella Buchii, Chapuis and Dewalque (1854). Bhynchonella 

 ranina, Suess (1860). 



This species is not so clearly distinguishable from E. variabilis 

 as R. pUcatissima, though it does not apparently graduate into it ; 

 and the fact of its occurrence on the same horizon in France, 

 England, and Germany induces one to regard it for the present 

 as a distinct species. 



B. oxynoti was found by Oppel in the zone of " Am. oxynotus " in 

 Gloucestershire. 



17. Bhynchonella bgretta, Deslongchamps. Bull. Soc, Lin. de 

 Normandie, vol iii., t. 4, f. 4-6 (1858). 



18. Ehynohonella subserkata, Munster; E. fallax. Deslong. 

 id. vol. vii., t. 3, f. 1-5 (1863). 



Both species recorded by Mr. Moore from the Middle Lias, 

 Whatley. 



19. Ehynohonella cokonata (Moore), Geologist, 1861, t. 2, f. 23. 

 Upper Lias, Ilminster.' 



20. Ehynohonella Jijkensis, Quenstedt {^Terebratula), Jura, 

 t. 41, f. 33-35. 



Mr. Lycett (Proc. Cotts. Club, vol. ii., p. 142. 1860.) records a 

 variety of the above species from the Tipper Zone of the Supra 

 Liassic Sands, and also a variety of R. flicatella, Sow., from the 

 Lower Zone. 



21. Crania Gxjmberti, Deslong., loc. cit. vol. vii., t. 3, f. 6-10. 

 Middle Lias, Whatley (Moore). 



22. Crania liassica, Moore. Quart. Journ. Geol. Soc, vol. xxiii., 

 p. 539. 1867. Lower Lias (Zone of Am. angulatus), Brocastle, 

 Stout's Hill. 



23. DisciNA Holdeni, Tate. Quart. Journ. Geol. Soc, vol. xxiii., 

 p. 314 (Nov., 1867). 



Eanges from the Zone of " Am. angulatus " to that of " A. Ibex " 

 in England and Ireland, and throughout the Lower Lias in the east 

 of France. 



24. DisoiNA orbicularis, Moore. Quart. Journ. Geol. Soc, vol. 

 xxiii., p. 540 (Dec, 1867). Possibly is the young of D. Holdeni. 

 Lower Lias, Shepton, Southerndown, and Bedminster. 



25. DisciNA Davidsoni, Moore. Geologist, 1861, t. 2, f. 16-18, 



^ Mr. Moore records R. subtetrahedra, Davids., in tte Marlstone of Ilminster; 

 M. subvariabilis, in the Middle Lias, Holwell ; and R. concinna, in the Middle Lias, 

 Camerton. I regard these as doubtful determinations.
