526 LONSDALE ON EOCENE CORALS FROM N. AMERICA, 



15. LlCHENOPORA. 



The imperfectly preserved coral assigned to this genus was less 

 than three lines in diameter, and was attached, except at the 

 slightly reflected margin, to a bivalve imbedded in the white lime- 

 stone of Eutaw. The surface was convex, and traversed by irre- 

 gular radiating rows of tubular openings. The intermediate or 

 non -projecting tubular openings were detectable in some places 

 between the ridges as well as in the centre ; and a weathered por- 

 tion displayed a congeries of tubuli of much less diameter than 

 those with projecting mouths. 



The coral resembled a Lichenopora of common occurrence at 

 Dinant and other Touraine localities, but the state of preservation 

 did not admit of a careful comparison. 



Locality. — Eutaw. 



16. Farcimia.* 



Of this coral, only "the lower part of an internode, less than a 

 line in length, and half a line in diameter, was observed. The 

 greatest number of consecutive cells was six, and of alternate rows 

 ten. The whole of the cells appeared to be immature, the surface 

 exhibiting large oval openings without a distinct mouth, and 

 bounded by a narrow band sloping downwards from the outer 

 margins of the cells. The foramen or chamber in which it is be- 

 lieved gemmules are matured, was distinct and placed as in Far- 

 cimia salicornia, as well as in Crag and Touraine species between 

 the consecutive cells. 



The condition and nature of the specimen did not permit a com- 

 parison with other known Farcimiae. 



Locality. — Rock's Bridge, Eutaw, in South Carolina. 



17. Vincularia. 



Four sided, slightly bent or straight ; opposite cells similarly situated ; boun- 

 daries of cells oval, surface with a narrow depression in the centre, mouth semi- 

 circular at the distal extremity of the depression. 



Seven fragments of this coral, the largest about a line in length, 

 and including four successive cells, supplied the materials for the 

 above imperfect notice. The characters will be found to agree 

 generally with those of Vincularia fragilis of De France and De 

 Blainville (Die. Sc. Nat. Atlas, and Man. d'Actinol. pi. 67. f. 3. ; 

 Glauconome tetragona Munster and Goldfuss, Petref. tab. 36. f. 7.); 



* Dr. Fleming's Farcimia is of posterior date to Cuvier's Salicornia or Sali- 

 cornaria, but the latter name had been applied, long before, to a well-known 

 genus of plants
