Description. — Shell quadrate, thin and lenticular. Brachial valve some- 

 what inflated and drawn out in the umbonal region to form an acute umbo ; 

 but depressed in the anterior portion with a tendency to form a slight sulcus. 

 Pedicle valve regularly convex in longitudinal section, \m\ somewhat lenticular 

 or even carinatcd in transverse section — its margin with that of the brachial 

 valve forming a very sharp edge. Beak ]irotruding, so that the deltidial 

 plates arc apparent ; beak-ridges not xcry acute ; foramen small. 



Remarks. — The characteristic features of this slender 

 little brachiopod are its quadrate outline, sharp margins, 

 lenticularity and protruding beak. There is no other shell 

 in the Witchellia-Gr\i with which it may be confused. Three 

 specimens have been obtained ; two from Cold Comfort 

 and one from the Rolling-Bank Quarry, Cleeve Hill, near 

 Cheltenham.
