8:2 BRITISH CRETACEOUS BRACHIOPODA. 



the Lamarckian and Sowerby collections, or from the study of a series of specimens 

 derived from the localities in which R. compressa occurs. 1 



In England, R. compressa is found in the Upper Green Sand of Chute Farm, near 

 Horningsham, at Halldown, in the Chloritic Marl of Chard, and other localities. On 

 the Continent, it abounds at Havre, Mans, and la Fleche (Jarthe). M. D'Orbigny also 

 states he has found it at Lattes, La Malle, and Escragnolles (Var.), at l'lle Madame, He 

 d'Aix, and at the Pont des Barques (Charente Inferieure). 



Plate XI, fig. 1. A well-shaped example, from the Upper Green Sand near Warmin- 

 ster, in the collection of Mr. Cunnington; it is identical in shape 

 to some found at Havre. 

 „ fig. 2. A very large individual, from the same locality, similar to the one 

 figured by Dr. Fitton as T. dilatata, Sow. (Geol. Trans., vol. iv, 

 pi. xiv, fig. 2.) 

 ,, fig. 3. Front view of a specimen from Chute Farm, in which the mesial fold 



is shifted to one side, from the cabinet of Mr. Cunnington. 

 ,, fig- 4. A malformation from the Chloritic Marl of Chard, which entirely agrees 



with Sowerby's type of Ter. dimidiata. 

 „ fig. 9. Another similar example, from the Upper Green Sand near War- 

 minster.

1 Some authors have attributed to this species Rhyn. alata (Lamarck, sp.) ; but as observed by 

 MM. D'Orbigny, Deshayes, and myself, T. alata is nothing more than a synonyme of Rhynchonella 

 (Anomya) vespertilio of Brocchi (' Conchologia Fossile,' 1814). Lamarck refors to pi. 245, figs. 2, a, b, of 

 the ' Ency. Methodique.' which figure certainly represents a shell indentical with the one illustrated by the 

 Italian author. R. vespertilio, at times, bears some resemblance to R. compressa, but is in general more 

 regularly convex and trilobed, with a much deeper sinus, and a more elevated mesial fold.
