258 BRITISH FOSSIL CORALS. 



of Kerry; Portrane and Malahide, in the county of Dublin. It exists also in Sweden, 

 Holland, and Russia. 



Specimens are in the Collections of the Geological Society, of the Poppelsdorff Museum 

 at Bonn, of M. de Verneuil, Paris, &c. 



This species much resembles Favosites alveolaris} with which it is often confounded, 

 but differs from it by the size and number of the marginal fossulse of the tabulse, as well 

 as by the calices being more unequal in size.

Corallum hemispherical ; common basal plate covered with a concentrically wrinkled 

 epitheca. Calices of equal size, and arranged in very regular series, that form somewhat 

 elongated hexagones, the opposite angles of which are of equal value. Each portion or side 

 of the walls generally present three series of pores, closely set, and arranged somewhat 

 irregularly. Large diagonal of the calices about half a line. 



Found in the Caradoc sandstone at Haverfordwest, and in the Wenlock limestone at 

 Marloes Bay, in Pembrokeshire. Professor «M'Coy has met with it also in Galway and 

 Kerry. 



Specimens are in the Collections of the Geological Society of London, and of the 

 Museum of Practical Geology. 



This fossil differs from the other species of Favosites by the regularity of its calices, and 

 the abundance of its mural pores.
