near Stroud, it contains masses of Corals, of the genera Tfeam- 

 nasircea and Isastrcea ; in others, as near NaUsworth, xt abounds 

 with numerous sheUs of the genus N^incea, forming there a 

 "Nerin^an Limestone;" in others, as at Cleeve and Cubherley, 

 the Marl is charged with BracUapodn, chiefly Terelrainla fimlr^a, 

 Sow., associated with a few Terehratula carinata, T.sulma.^Uata 

 and m.yncJ.<^ella l^cetti. The fauna of the Oolite Marl xnduced 

 nxe, in a former paper thereon, ix> consider this bed as the produ 

 of an ancient Coral-bank. "The direct evidence of the existence 

 of Zoantharia in considerable numbers, added to the abundance 

 of long spiral univalyes belonging to the genera C/^emmfeta and 

 J^erml, which are known to nestle in Coral formations, together 

 with the indirect evidence of a super-abundance of BracUofoda 

 added to the Hthological character of the Marl itself, which 

 appears to be the product of Coral-mud and other dehru, leads 

 to the conclusion that the Fimhria-hed was a portion of a 

 Jurassic Coral-bank* in the Oolitic Sea."
