CARBONIFEROUS AND PERMIAN FORAMINIFERA . 



These probably find their equivalents in the Yoredale rocks, but the beds below the 

 true lower shales form a sort of intermediate group corresponding with those of North 

 Devon. With one exception the beds which have furnished Foraminifera all occur in the 

 Upper Mountain Limestone (II, a), the exception being a bed in the lowest part of the 

 Middle Mountain Limestone (II, 3) marked in the table " Great Quarry, near Lon(jisjnnosa 

 bed." To my friend Mr. W. W. Stoddart, F.G.S., of Bristol, whose name is identified 

 with the geology of the Clifton Rocks, I am indebted for ample supplies of material from 

 both sides of the River Avon, as well as for accurate geological information as to the 

 localities whence they were obtained. 



Gloucestershire. 



In the loicest part of the Middle Mountain Limestone. 



37. Great Quarry, near the " Longispinosa bed," Bristol. 



In the Upper Mountain Limestone. 



38. Bridge Valley Road, near Clifton Down. 



Somersetshire. 



In the Upper Mountain Limestone. 



39. Leigh Woods, Foraminifera-bed. 



40. Leigh Woods, between Foraminifera-beds. 



41. Opposite Point, Leigh Woods, Foraminifera-bed and parting. 



42. No. 2 Foraminifera-bed. 



These four localities are all in the Clifton district. 



43. Backwell, a single mounting of Foraminifera, probably of similar age to 



the foregoing; in Mr. C. Moore's collection. 

 160. Bath. In Mr. C. Moore's collection are one or two specimens of a very 

 granular variety of Trochammina incerta collected from the sediment of 

 the Bath mineral waters. These are presumably Carboniferous, but it 

 has not been thought worth while to devote a column in the table to 

 them.

The comparative completeness of the Distribution Tables referring to the Scotch 

 Carboniferous system is mainly due to the friendly aid of the officers of the Geological
