This is a tolerably plentiful species occurring chiefly in the 

 Sowerbyi zone. It seems to be distinguished from the typical 

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

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

 Jurassiques, plate 59, gives several figures of Terch. 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. 

 Boitriige, plate xxxii. (9), figures 1-2 gives Tcreh. globulus, with 

 which our young specimens of Tercb. Eudesi seem to agTee. 

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

 unable to say.
