344 BRACHIOPODA OF THE 



15. Rhynchonella, sp. Dav., B. S. Sup., PI. XXXVIII, fig. 32. 



Of this small species a single dorsal valve was found by the Rev. H. Winwood in a 

 Budleigh-Salterton pebble. In shape it is marginally circular, as broad as long, with 

 two short small ribs quite close to the front ; the remainder of the valve is smooth. 

 Length 5 lines, breadth the same. 



This ffliynclionella is quite distinct from all the other species of the genus we find in 

 the Budleigh-Salterton pebbles ; but with such scanty material it is not possible to 

 attempt a specific identification.

Shell small, as wide as long, or rather longer than wide. Ventral valve almost 

 uniformly convex, with from eighteen to twenty simple ribs. Dorsal valve regularly 

 convex, and ornamented like the other valve. Two specimens measured — 

 Length 3, breadth 2| lines.

Of this small species I have seen a few internal casts and external impressions, but 

 not sufficiently numerous to enable me to give a complete description of the shell. It 

 has been found in company with Orthis Monnieri and Strophomena Budleighensis, and 

 is consequently of Devonian age.
