A small, very variable species of Rhynciionella from the Inferior Oolite {Am. 

 Sowerybi zone) of Bradford Abbas, Dorset, and from Corton Denham, Somerset, 

 has been referred by Mr. S. S. Buckman to the shell figured by Szajnocha. It has 

 some ten angular ribs on each valve, of which four would occupy the mesial fold. I 

 have not been able to compare the shells referred to this species with foreign types, so 

 the identification must be considered as provisional. The shell was named by Suess, but 

 described by Szajnocha.

Shell transversely oval, wider than long. Dorsal valve very moderately convex, with 

 a broad convex mesial fold, of moderate elevation, commencing to rise at about the middle 

 of the valve ; ventral valve deep and very convex, especially posteriorly, with a concave 

 sinus commencing at a little distance from the beak, and widening as it nears the front ; 

 beak incurved, with a small, circular foramen under its angular extremity. Surface of 

 the valves covered with numerous small, radiating riblets. 

 Length 6, breadth 7, depth 4 lines. 



Obs. — This shell was obtained by Mr. S. S. Buckman from the Inferior Oolite, Am. 

 Humphriesianus zone, at Halfway House, Sherborne, in Dorsetshire and sent to me for 

 description. It is intermediate in shape between R. Dundriensis and Rh. senticosa, but 

 has no spines and is easily separable from both.

I have been recently informed by Mr. II. Keeping that the above-named fossils, 

 described in pages 227 and 228, PL XXIX, figs. 20 and 21, of my 'Jurassic Supple- 

 ment, 5 are not British, and do not occur in the Middle Lias near Chideock ; and that
