Vol. 67.] PAUNAL HORIZONS IN THE BRISTOL COALFIELD. 333 



Pterinopecten papyraceus (Sowerby). 



A very small fragment of the shell of this species was found in 

 massive dark shale at Horizon 3, below the Bedminster Great Vein. 

 The close radiating ribs of this species are so typical, that even 

 minute fragments can be recognized. 



Horizon and locality. — In dark shale, about 279 feet below 

 the Bedminster Great Vein, Lower Coal-Measures, South Liberty 

 Colliery, Bristol. 



Npcula oblonga M'Coy. (PI. XXVII, fig. 17.) 



Two good examples of this species were obtained at Horizon 3. 

 The shells measure 7 millimetres in antero-posterior diameter and 

 4 in depth. 



Dr. Wheelton Hind * describes this species as very rare, and as 

 only known to occur in the Upper Limestone Shales of Scotland, and 

 in arenaceous shale at Drumlish (Ireland). 



Horizon and locality. — In dark shale, 279 feet below the Bed- 

 minster Great Vein, Lower Coal-Measures, South Liberty Colliery, 

 Bristol. 



BRACHIOPODA. 



Lingula mytiloides Sowerby. 



In Lower Coal-Measures at the Easton and Hanham Collieries 

 occurs a fine black shale crowded with hundreds of the shells of 

 Lingula. Most of the shells are small, but admirably preserved. 

 On the spoil-heap at Hanham Colliery, where the greater number 

 were obtained, much of the shale has been fired ; but even in burnt 

 material the shells are distinctly shown. They vary in length from 

 2 to 6 millimetres, are broadly oval, and have moderately swollen and 

 often highly polished umbones. At Newbury the species is found 

 in a dark-blue Lower Coal-Measure shale : the shells are more 

 uniform, than at Easton or Hanham, the length of the valves 

 varying between 3 and 5 mm., and in all cases the periostracum 

 is much wrinkled. The shales at Easton and Hanham Collieries are 

 typical ' Lingula Shales,' and very similar to those found at much 

 lower horizons in the Ashton-Vale Colliery, Bristol. 



Horizons and localities. — In the neighbourhood of the 

 1 Five Coals ' Seam, Easton Colliery, Bristol ; ? Roof of No. 1 Seam, 

 Newbury Colliery, Coleford, near Radstock. 



GASTEROPODA. 



A few gasteropods were found in Lower Coal-Measure shales 

 thrown out upon the spoil-heap at South Liberty Colliery ; but, with 

 one exception, all were minute and too destitute of determinable 

 characters to be described.
