28 Alfred Beli—British Upper Tertiary Corals. 
ViI.—Britisa Uerrer Tertiary Corats. 
By Aurrep Brut. 
RITERS on Fossil Corals seem to ignore the existence of Corals 
in our later Tertiary formations. They are certainly not 
common. The following reference and species have come under my 
notice: Caryophyllia clavus, Scacchi var. borealis, Flem., Lancashire 
drift (see Geologist, 1845, p. 124). Caryophyllia clavus var. Smithit, 
Stokes, Raised beach, Portrush, Co. Antrim (Portlock, Geol. London- 
derry, etc.). Sphenotrochus Wrightii, Gosse, from the Clyde beds, by 
Messrs. Crosskey and Robertson. To these I may add a fine calice 
of the Norway branching Coral Lophohelia prolifera, Ed. and H., 
from the interglacial sands of King Edward, N.B., and a single young 
example of Sphenotrochus Macandrewanus, EH. and H., from the Raised 
sea-bed, Largo Bay, Fife. 
T'wo species occurring in the disturbed portion of the Suffolk Red 
Crag appear to be of Diestien origin, viz. Solenastrea Prestwichit, 
Dune., present in beds of that age in Belgium (Brussels Museum), 
and a stout form of Flabellum, whose affinities are rather to 
F. appendiculatus, Nyst, than to F. Woodii of the Coralline Crag, 
to which it is commonly referred. I judge this after an examination 
of a large number of specimens of the different species— mostly worn 
and rolled examples. 
The “ Reed Coll.,” York Museum, contains a minute Sphenotrochus 
not more than 4; inch in height, which I obtained from the well- 
known Chillesford Sands at Aldeby. I have only seen this one 
example, and have, pending further discoveries, given it the trivial 
name of S. parva. 
The Crag Sphenotrochi would probably repay further examination, 
as in several instances I have noticed that the costez instead of 
presenting the usual strait parallel arrangement, sometimes wavy 
at the lower end, are strongly wavy, the projections interlocking one 
within the other 
P.S.—Since writing the above Mr. Tomes, F.G.S., has kindly 
examined the corals referred to in the last paragraph, and describes 
them as follows :—

The corallum is of equal breadth for the whole of its height, but 
it is very thin at the base. The curve of the margin of the calice in 
the long direction is about the same as in Sphenotrochus intermedius. 
The long diameter of the calice to the short one is as 6 to 4. There 
are twenty-four septa and the primary and secondary ones are united 
to the columella by trabicule, which are not in pairs, but are single. 
A few large papilla appear on the sides of the septa, which have 
also horizontal ridges ending in simple blunt teeth on their inner 
margin. These with the growth of the corallum are elongated 
inwards and become trabicule, and are attached to the columella. 
The latter part as in Sphenotrochus intermedius is notched in the 
middle. The costez are very uniform in size over the whole of the
