SUPPLEMENT TO THE BRITISH 



of the same plate : Schloenbach has given to this last the name of Tereh. StrombecM ; it 

 is the one which M. Pictet has described under the name of Tereh. hippopus" I 

 entirely coincide with Dr. U. Schloenbach and M. de Loriol in the view they have 

 taken of this matter; and I am even not quite certain whether the Tealby specimens 

 referred by Mr. Judd to T. hippopus really belong to that form, although some speci- 

 mens approach it more than any others I have seen. 



It must be allowed that the many specimens I have been able to examine of the 

 typical form from the Upper Salzgitter Hills, in Hanover, have presented a peculiar 

 appearance not observable in the Tealby specimens referred to that species. They bear 

 much more resemblance to the shell described and figured by Dr. U. Schloenbach in 

 1868 ('Ueber die Norddeutschen Galeriten-Schichten und ihre Brachiopoden-Fauna,' p. 31, 

 pi. ii, figs. 10 — 12), under the name of Terehratula (?) defluxa, and it is possible that the 

 British form might be more properly placed under that species. Anyhow, it is 

 desirable to add a provisional varietal designation after the name hippopus, as 

 none of our British specimens entirely agree with Roemer's type, but represent a larger 

 shell. Some of the Tealby specimens, moreover, bear much resemblance to certain 

 examples of W. impressa from the Oxford Clay. Under these circumstances, I have 

 deemed it advisable not to reproduce the synonyma and references (mostly incorrect) 

 that have been published of Roemer's species. 



Position and Locality. — This species was discovered in England for the first time by 

 Mr. Judd, who found it rather plentifully in a sandy limestone, provincially known as 

 " Greystone," which he refers to the Middle Neocomian, at Acre House, near Tealby, 

 in Lincolnshire. I have picked up specimens agreeing with the Tealby variety in the 

 Neocomian at Escragnolles (Dept. du Var), France.

Spec. Char. — Shell nearly circular or moderately elongated, oval. Ventral valve 

 deep, longitudinally keeled, flattened laterally ; beak incurved and truncated by a cir- 

 cular foramen ; deltidium small, in two pieces ; beak-ridges sharply defined. Dorsal 

 valve of small depth, convex at the umbo, broadly concave or sinuated anteriorly ; surface 

 smooth, marked at intervals with concentric lines of growth. 

 Length 13, width 11, depth 8 lines.

Ohs. — I am somewhat puzzled how to deal with this shell. It differs from W. 

 hippopus and W. StrombecM very materially, and, although some exceptional specimens, 

 such as fig. 6, bear a certain resemblance to W. Woodwardi, the greater number (figs. 

 7, 8, and 9) differ from it entirely.
