remarks on Lithostrotion ensifer Edwards & Haiine ; and in 

 1905, in 'The Palaeontological Sequence in the Carboniferous 

 Limestone of the Bristol Area ' Q. J. Gr. S. vol. lxi, p. 199, he 

 stated the exact palaeontological horizon at which the species 

 occurs — namely, the upper part of the Dtbunophi/lhcm Zone : 

 that is, Subzone of Lonsdaleia florifovmis (D,).

External Characters. (PI. XXIII, tigs. 1, 3, & 4 ; 

 PL XXIV, tig. 2.) 



The corallum is typically depressed, and the distal surface is 

 usually flat. Nevertheless, the species occurs in more tumular 

 masses, and mav display a mammillate surface (see PL XXIII, 

 fig. 4). 



The dissepimental tissue, which constitutes the greater part of 

 the skeleton, is often unevenly developed ; consequently, the cali- 

 cular depressions may be near together, or widely separate : these 

 depressions are not infrequently bounded by a sharply-elevated 

 border (PL XXIII, tig. 1). A columella is present, and is often 

 prominent. 



Epitheca clothes the lower surface of the corallum.
