TERTIARY CORALS. 53 
Two of the species, viz., Lobopsammia cariosa, Goldf., sp., and Madrepora Solandert, 
Defrance, sp., are found in the Eocene beds of the Paris Basin; they have not, however, 
been noticed either in the London Clay or in the Bracklesham and Barton beds in 
England. 
The Madrepora Solanderi is a species of very doubtful value, and the reasons for this 
assertion have been already given. 
The Lobopsammia cariosa is found under the name of L. dilatata, Rootes at Latdorf. 
The Litharea and the Avopoya from Brockenhurst have no very close specific alliance 
with the forms of the genus found in the London Clay and the Bracklesham beds. 
The Nummulitic coral-fauna’ of Italy, Sinde, &c., has no species in common with that 
of Brockenhurst ; and the researches of Reuss and Roemer in the coral-faunz of the 
Tertiary series termed Lower, Middle, and Upper Oligocene, have not produced any 
results which enable me to correlate any one of those series with the coraliferous beds at 
Brockenhurst. 
The Miocene coral-fauna has no specific relationship with that under consideration. 
It becomes evident from these considerations that the new coral-fauna has very 
slight resemblances and affinities with those already described. 
The Brockenhurst corals are, therefore, very remarkable; the absence of simple forms 
and the presence of species of Madrepora, Avopora,’ and Solenastrea indicate the former 
existence of a vigorous polype-growth, and of all the physical conditions now observed 
near and about coral-reefs. The great size of the trunk of Madrepora Anglica is 
especially significant. It may be still true that this coral-fauna was a local one, for at 
the present day the distinction between reef-, barrier-, and simple coast-corals is suffi- 
ciently determinable. 
The coral-fauna of the so-called Lower Oligocene beds of Germany is associated with 
the mollusca which characterise the Brockenhurst beds and their equivalents in the 
Headon series of the Isle of Wight.’ It is distinct from the coral-fauna of Brockenhurst, 
although the correlation of the strata can be established from the study of the Mollusca ; 
hence the probabilities of the Latdorf coral-fauna being that of a coast-line, and of the 
Brockenhurst being that of an oceanic and reef area, are great. 
The coral-fauna of Brockenhurst is more recent than that of Barton and evidently 
flourished under very different physical conditions. It is older than the Falunian and 
Crag-faunze. 
' The coral-fauna of the London Clay, and of the Bracklesham and Barton beds, and of the Paris Basin, 
is contained to a certain extent in the great Nummulitic coral-fauna of Southern Europe and India; but 
there were clearly two coral-provinces during the early Tertiary period, just as there are at the present day— 
the West Indian and the Pacific. 
? Avopora is represented in existing reefs by many tabulate corals.
