294 CARBONIFEROUS LAMELLIBRANCHIATA. 



The shell referred to E. unioniformis by Salter as occurring in a marine bed 

 in the South Wales coal-field is much too quadrate posteriorly, and should be more 

 correctly named E. oblonga. 



There are several species described by de Koninck which I think should be 

 more correctly referred to Phillips's shell, — E. ? precox, E. tenuilineata, E. ? 

 pulchella, E. ? decorata, and E. ovata. These are all transversely ovate in shape, 

 and have a similar external ornament, comparatively smooth and regular, but 

 becoming more marked in large examples towards the lower border, and all come 

 from the same horizon, Etage II of Pauquys and Waulsort, with the exception of 

 E. ovata and E. prselat a, which are from the lowest division, Tournai. 



E. ? anodonta, de Koninck, is another of this author's species which I should place 

 as a synonym of E. unioniformis. This species is stated to be founded on a 

 single specimen, but two are figured, and the specific character is the compara- 

 tively compressed condition of the valves. 



Mr. R. Etheridge, jun., figured a specimen of E. unioniformis from the 

 Encrinite-bed of St. Andrews (op. supra cit.), and remarks on the wide distri- 

 bution of the species, which is said to occur in Russia. 



Struve ('Mem. Acad. Imp. des Sci. de St. Petersbourg,' torn, xxxiv, No. 6, 

 p. 104) quotes E. unioniformis as occurring in the Productus giganteus zone, and the 

 coal-bearing beds below, of the Moscow coal-basin.
