would be determinable, but there seems to me to exist so many passage forms between 

 the two that it is hard to know where to draw the line. 



My first attention to British specimens of this so-termed species is due to the Rev. G. 

 F. Whidborne, who sent me several examples under the name of Wald. cor, which he 

 had collected from the Middle Lias at West Tyning near Radstock. 



For the reception of this shell, together with W. numismalis, W. quadrifida, W. cornuia, 

 W. Egena, and similar forms, Mr. Bayle, in vol. iv of the 'Explication de la carte 

 geologique de France,' proposes the generic name of Zeilleria, and this has been adopted 

 by M. Douvillie and Professor Zittel, but I am at a loss to perceive any valid grounds 

 for removing it and the other named species from King's excellent genus Waldheimia.

PI. XXI, figs. 1—7 ; Appendix to Sup- 

 plements, Vol. V, PI. XX, fig. 14 ,14 a, b. 



At p. 1C2 of my ' Oolitic and Liassic Supplement' I described some of the shapes 

 assumed by this variable species. Since then I have received from the Rev. F. Smithe 

 an extreme variation similar to a specimen of W. sub-numismalis figured by M. E. Des- 

 longchamps in pi. xxix, fig. 4, of his ' Brachiopodes Jurassiques.' By extreme shapes we 

 may connect W. numismalis, W. sub-numismalis, W. cor, W. quadrifida, W. Verneuilii, 

 Desk, and some others, but the prevalent shape and the larger number of specimens of 

 each of these so-named species are distinct and characteristic. Therefore it would 

 not be right, I think, to club them all under one name. 



The shell under notice was procured by the Rev. F. Smithe from the Am. spinatus 

 zone, Middle Lias, Churchdown, Gloucestershire. The French examples come from the 

 same geological horizon.

Since describing this species (?) at p. 18G of my 'Jurassic Supplement,' Mr. E. 

 Cleminshaw has found a specimen of the shell in the Inferior Oolite at Corton, near 

 Sherborne, Dorset, measuring 9| lines in length by the same in breadth, and 5 lines in 

 depth, and so much resembling specimens of W. Lycetti in size and shape from the Upper 

 Lias of Bloxham near Banbury, that I much fear Wald. anglica can hardly be specifically 

 distinguished from my previously described W. Lycetli.
