52 BRITISH FOSSIL CORALS. 
The calices are either scattered irregularly over the papillate coenenchyma or are 
aggregated in sets; a parent corallite being surrounded by its buds. The calices are 
small but slightly projecting, tubuliform and finely costulated, the costee being lost in the 
irregular, porose, and papillate common tissue. Some are not costulated, but are sunken 
in the coenenchyma, and all are circular in outline with thickish walls. 
The septa are as is usual in the genus; and the opposite primary septa frequently 
join by their inner ends. There are six large and six small septa. 
The coenenchyma is highly cellular, and its free surface is almost aciculate with sharp 
papilla. Locality. Brockenhurst. In the Museum of Practical Geology, London. 
These species of the genus MMZadrepora are all new to the British coral-fauna. 17. 
Solanderi is an indifferent species, for there may have been any amount of ornamentation 
on the coenenchyma, and the calices may have been very prominent and costulate, but 
nearly every detail has been worn off the specimens. Many well-characterised species, 
were they worn and rolled, would present the appearance of the typical specimen of 
M. Solanderi. 
Madrepora Roemert is well characterised by its form, its distant tubuliform calices with 
costulated external surfaces, and by its very granular and echinulate coenenchyma. The 
species most closely allied to J/. Roemeri is M. granulosa, Edwards and Haime, a recent 
form from the Ile de Bourbon. 
The Madrepora Anglica is a well-marked species, and is allied to WZ. crassa, Edwards 
and Haime, a recent form whose locality is unknown. 
The genus Madrepora comprehends at least ninety-two species, of which only eight are 
fossil. The Paris Basin and the ‘Turi Miocene have hitherto been the localities whence 
the fossil species have been collected; and now the Brockenhurst beds must be admitted 
amongst the strata whose remains indicate the former existence of coral-reefs exposed to 
a furious surf and the wash of a great ocean. 
‘lhe Brockenhurst J/adrepore do not resemble, except generically, the species from 
‘Turin. 
The recent species are found all over the Pacific, the Indian Ocean, the Caribbean 
Sea, and one species has retained its position in the White Sea, near Archangel (17. 
borealis, Edwards and Haime). 
As yet the very fossiliferous Tertiary strata of the islands of the West Indies have 
not yielded any fossil M/adrepora.
