16 THE BRACHIOPODA. 



Dimensions. Type specimen: Length, 14; breadth, 13; 

 depth. 8 lines. 



Localities. Stoke Knap(Dorset) and near Haselbury(Somerset), 

 characteristic of the Opalinum zone in this district and rather 

 abundant ; also Frocester Hill (Gloucestershire) and near Poitiers, 

 Niort, Saint Maxient, Montreuil-Bellay, &c. (DeuxSevres), and 

 Sarthe, Conlie, &c.

This is a tolerably plentiful species occurring chiefly in the 

 Sowerbyi zone. It seems to be distinguished from the typical 

 form of Tereb. glolata, chiefly by its deeper biplications and 

 more globose form. Mr. E. Deslongschamps in his Brachiopodes 

 Jurassiques, plate 59, gives several figures of Tereb. Eudesi ; 

 most of which, however, do not seem to me to agree with David- 

 son, plate xiii., fig. 4, which is the figure Oppel quotes. They 

 may, however, be varieties. Dr. Waagen in Geogn. Paliiont. 

 Beitriige, plate xxxii. (9), figures 1-2 gives Tereb. globulus, with 

 which our young specimens of Tereb. Eudesi seem to agree. 

 Whether Tereb. globulus may be really distinct or not I am 

 unable to say. 



Dimensions. Length, 14; breadth, 12; depth, 10 lines. 



Localities. Bradford Abbas, near Sherborne, etc. (Dorset) ; 

 near Gorton, etc. (Somerset) ; also Dundry (Somerset), and la 

 Verpilliere and Caen (Calvados). 



Obs. An elongated variety of Tereb. Eudesi often occurs in 

 which the folds are more angular and closer together. This
