JURASSIC AND TRIASSIC BRACHIOPODA. 185 



172. Waldheimia, sp. (?) Sap., PI. XXIV, fig. 20. 



In the Lower Calcareous Grit or zone of Am. perarmatus of Bramberry Hill, Suther- 

 landshire, internal casts of an undetermined species of Waldheimia have been collected by 

 Prof. Judd, but not sufficiently complete (the shell being absent) to warrant a specific 

 identification. These oval internal casts are very remarkable on account of the very 

 great length of the longitudinal fissure in the dorsal valve, indicating the presence in the 

 smaller valve of an unusually long and large septum. In shape these casts most approach 

 W. /tumeralis, but the length of the septum is very different from that observable in the 

 last-named species. 



173. Waldheimia cardium, Lamarck. Dav., Ool. Mon., p. 43, PI. XII, figs. 13 — 18; 



Sup., PI. XXIV, figs. 21, 22. 



I have very little to add to the description I gave of this species at p. 43 of my 

 Oolitic Monograph. I may, however, observe that in the opinion of Mr. C. Moore the small 

 T.furcata of Sow. is not a young age of W. cardium, but a well-defined small species of 

 Terebratula, its loop being doubly attached, as will be seen in the illustration we give in 

 PI. XIV, fig. 16 of this Supplement. 



This shell occurs in the Great Oolite and Bradford Clay of Bradford, and Tetbury 

 Road Station. The Rev. P. Smithe informs me that he has found it in the Porest 

 Marble of Malmesbury. Mr. J. P. Walker assures me also that a variety he distin- 

 guishes by the name of Leckhamptonensis occurs (but very rarely) in the Inferior Oolite 

 or Pea Grit at Leckhampton Hill, near Cheltenham, and in the same formation at 

 Bradford Abbas in Dorsetshire (Sup., PI. XXIV, fig. 21). In the last-named locality, 

 however, it must be exceedingly rare, for out of upwards of 1000 specimens from the 

 district lent me by Professor Buckman and Mr. Darell Stevens, I did not find a single 

 example referable to the species or variety above named. There is in the Museum of 

 the Geological Survey, Jermyn Street, a specimen from the Inferior Oolite of Andovers- 

 ford. This variety is more elongated and ovate than the specimens from the Great 

 Oolite and Bradford Clay, the beak is less incurved, and the beak-ridges are sharper. 

 Pine examples may be obtained from the Forest-marble at Islip in Oxfordshire.
