Colin. L. Richardson. 



Description. — Shell globular, coarsely-ribbed with a low mesial fold with 

 three prominent ribs. There are four prominent ribs on each lateral area 

 of the brachial valve. The beak is acute, prominent and incurved, but well 

 separated from the umbo. 



Remarks. — In aged specimens of this species the shell 

 is thickened by increment along the anterior edges of the 

 valves in such a manner that the front is almost upright. 

 The deltidial plates are well displayed and practically surround 

 the foramen. 



A number of specimens have been obtained from the 

 type-locality and from beds of the same age at the Frith 

 Quarry, near Painswick.

Colin. L. Richardson. 



Description. — ^hcll sub-globular and well-ribbed. A front view (pi. VII., 

 fig. 7c) shows a marked fold, but the contour of the shell is unaffected or only 

 slightly affected by it. The beak is acute and incurved. 



Remarks. — Rhynchonella selsleyensis is very abundant 

 in a bed lying immediately on the Upper Trigonia-Grit at 

 Selsley Hill.^ The form has also been noted at several other 

 localities in the Cotteswold Hills.
