50 BRITISH FOSSIL CORALS. 
Srotion—MADREPORARIA TABULATA. 
Famity—MILLEPORID Ai. 
Genus—AXOPORA. 
Axopora Micurxini, Duncan. Plate VII, Figs. 11—15. 
The corallum is large, very irregular in shape, and marked by inequalities 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 tabule 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, Hsq., F.G.S. 
Axopora is a very remarkable genus, for its corallites have no septa, but a great 
columella and tabulze. The tabula 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 Holorea Parisiensis, which is synonymous with Alveolites Parisiensis, Michelin, 
and which was described by MM. Milne-Edwards and Jules Haime, im the first part 
of their Monograph, has been determined by them to be an Awopora. ‘The Axopora 
Michelini is a very large and fine form, and is closely allied to Axopora Solanderi, 
Defrance, sp., and less so to 4. Fisheri, Dunc., but it differs very decidedly from 
A. Paristensis.
