104 BRITISH FOSSIL CORALS. 
form, its costula, the mode of arrangement of its superficial calices, its papillose columella, 
and the complete absence of intercalicular ridges. 
Some other fossil corals are mentioned by geologists as having been met with in the 
Coral Rag of England, but we have not been enabled to ascertain the character of these 
species, and can at present only recall what our predecessors have said concerning them, 
without pretending to distinguish them from those described in this chapter.

at Malton, and has been only characterised by the very 
unequal size of its cells.)

CHAPTER X. 
CORALS FROM THE GREAT OOLITE. 
The Corals from the Great Oolite of England, which have been submitted to our 
investigations, belong to twenty-two distinct species, and, as well as those met with in the 
upper deposits of the same geological group, are for the most part Astreide; together with 
eighteen species belonging to this family, we have only seen two species of Fungide and 
two of Poritide. 
Three of these fossils (Cladophyllia Babeana, Stylina solida, and Anabacia orbulites), 
are found in the Inferior Oolite as well as in the Great Oolite; one (Zhamnastrea concinna) 
appears to exist in both of these formations as well as in the Coral Rag, and six species 
have been met with in the Great Oolite in France as well as in England ; but the British 
palzontological Fauna of this period presents sixteen species that have not as yet been 
discovered on the Continent. 
The principal localities at which the species here described were found are the environs 
of Bath, Minchinhampton, Bradford, and Stonesfield.
