[Aug. IQII, 



The spoil-heap of the Foxcote and Lower "Writhlington Collieries 

 also yielded Anthracomya lanceolata, A. phillipsi, A. Icevis, A, 

 minima, Naiadites elongata, and Pseudoedmondia sp. no v. 



(9) Dunkerton. 



The Dunkerton Old and New Pits pass through the First or Rad- 

 stock Series of coals, which, as we have seen, also occur in the 

 Ludlows and Middle Pits. In hard micaceous shale from Dunkerton 

 New Pit I obtained the posterior half of a single fish-scale of 

 Ccelacanthus cf. elegans. 



Regarding the Upper Division of Radstock as a whole, it may 

 be said that the Farrington or Lower Series promises to be especially 

 productive, if it can be worked in regular order and thoroughly ; 

 but this is a costly and difficult process. Access to the beds can 

 only be obtained in the mines, and in galleries which usually are 

 heavily timbered and constantly traversed by loaded wagons.

This species occurs in the shale bearing Leaia leidyi, var. salteriana 

 at Coalpit Heath, but in less abundanee than that fossil. Isolated 

 and well-preserved examples are rare, the specimens usually forming 

 dense clusters, which must have numbered some hundreds of indi- 

 viduals. The valves in these clusters are crushed and ill-defined, 

 but in most cases a broadly oval outline can be distinguished, as also 

 faint traces of concentric striations. Isolated examples are better
