The corallum is large, very irregular in shape, and marked by inequahties of the 

 surface. The ccenenchyma is abundant, very finely reticulate, and is dotted by numerous 

 and very small calices, which are not very deep, and often irregular in shape ; they are 

 not separated by ridges. The columella is formed by longitudinal fibres, and projects but 

 slightly at the bottom of the calice ; it is slender, very long, and often wavy. 



There are no septa. 



The tabulae are horizontal, not numerous, very small, and do not go through the 

 columella, and divide the corallite off perfectly. 



A variety of this species is in the form of a flat cake, and its corallites are very long 

 and thin.^ 



Locality. Brockenhurst. In the collection of Frederick Edwards, Esq., F.G.S. 



Axopora is a very remarkable gemis, for its corallites have no septa, but a great 

 columella and tabute. The tabulae do not pass through the fasciculate columella, and 

 yet they cut off all the space below them from that nearer the calice. 



The species are not numerous ; they were probably rapid growers, and the structures 

 entering into their composition are so simple that it is very difficult to determine specific 

 distinctions. 



The Eoloraea Parisiensis, which is synonymous with Alveolites Parisiensis, Michelin, 

 and which was described by MM. Milne-Edwards and Jules Haime, in the first part 

 of their Monograph, has been determined by them to be an Axopora. The Axopora 

 MicJielini is a very large and fine form, and is closely allied to Axopora Solanderi, 

 Defrance, sp., and less so to A. FisJieri, Dune, but it differs very decidedly from 

 A. Parisiensis.
