The species of the genus Solenastrea from Brockenhurst form a very in- 
teresting series, which might almost be made a subgenus. The high septal 
number in conjunction with the highly inclined endotheca and the defective 
columella characterize the group. The species described by Reuss from the 
Castelgomberto district, and those from Ghent and Touraine by MM. Milne- 
Edwards and Jules Haime, are very distinct from the Brockenhurst species. 
Those I have published in my ‘ West-Indian Fossil Corals,’ and a species 
noticed by Michelotti and Duchassaing, from St. Thomas’s, are equally 
remotely allied to the British forms. 
The recent Solenastree are world-wide—the Red Sea, the Indian Ocean, 
and the Caribbean Sea being their favourite localities. 
The Madrepore from Brockenhurst are very interesting species, for fossil 
forms of the genus are very rare. Madrepora Solanderi, Defrance, was 
known as a form from Anyert and Valmondois; but it appears to me that 
the correct geological age of the deposit whence it and another coral (also 
common to the Brockenhurst, viz. Lobopsammia cariosa) came is not free from 
doubt. It is not improbable that they are true Oligocene corals, especially 
as the last-named species is identical with Lobopsammia dilatata, Riémer, 
from Latdorf. 
_ Madrepora Anglicais a grand form, with a great trunk and short branches, 
equalling in size any of the most luxuriant recent species. It is allied to 
Madrepora crassa, Ed. & H., from the-Pacific and Southern oceans. The 
genus comprehends nearly 100 species now flourishing; but the fossil forms 
are only eight in number. The recent species are found, for the most part, 
in the boiling surf of the reef, in every part of the globe where the condi- 
tions for reefs exist. 
_ A.xopora is a genus which has absorbed the genus Holarwa. The species 
have very rudimentary septa, enormous columelle, well developed tabule, 
and a reticulate ceenenchyma. The species are found in the Eocene of 
Great Britain and France, and at Brockenhurst, and they are all closely 
allied. 
Litharewa Brockenhursti is remotely allied to the species from the Brac- 
kJesham beds and the French and the Javan tertiaries. The genus is extinct ; 
but the Brockenhurst species, although not the latest in geological age, points 
to Goniophora, a large recent genus of Pacific and Red-Sea corals. 
The species of Balanophyllia from Brockenhurst, like that from Brackles- 
ham, has no epitheca, but its large base, distinct costa, and very granular sur- 
face render it easily distinguishable. Reuss, F. Rémer, and Philippi have 
described species from the Lower Marine Sand of Weinheim and Latdorf ; but 
they are not closely allied to the species under consideration. 
As the genus is present in the whole of the Cainozoic coralliferous beds 
of Great Britain, and is represented in the existing South British and 
Mediterranean seas, the following Table may be useful concerning its divi- 
sions. .
