‘Vol. 58.] BRACHIOPODA OF THE MALVERN HILLS, 145 
soealis of the Paradoaides-beds of Sweden, but the apex of the 
latter 1s more central and it occurs on a different horizon. A form 
found in the Stockingford Shales at Purley Park near Nuneaton is 
very similar, but possesses in addition to the concentric markings 
very close radiating striae.
