Mr. R. Tate states that this minute and rare species has been found in the Middle 

 Lias. Zone of Am. margaritatus of England, but he does not give the locality. I have 

 never seen any British example, so I cannot describe or figure it. It has been well 

 described and beautifully illustrated by Mr. E. Deslongchamps in his ' Brachiopodes 

 Jurassiques,' who informs us that it occurs in the Middle Lias of Eontaine-Etoupe-four, 

 May, and Bretteville-sur-Laise in the Department of Calvados.

Spec. Char. — Shell very small, almost circular, and nearly as broad as long, widest 

 towards the middle, sides rounded, front straight or slightly indented. Valves moderately 

 convex, ventral valve with a shallow sinus, extending from the back to the front, beak 

 moderately incurved and truncated by a rather large foramen. Walls laterally margined 

 by small deltidial plates, which do not unite in front. Dorsal valve rather less 

 convex than the opposite one, with a median depression commencing at about half the 

 length of the valve and extending to the front. Surface of both valves covered with 

 numerous fine radiating ribs, of which a large number are due to intercalation and
