CORALS OF THE CRAG. ll 
whereas the B. prelonga and the B. Gravesii' of the Paris basin have a narrow peduncle ; 
from B. cylindrica® (a Miocene species found at Turin and Verona), 2. geniculata® (a fossil 
belonging to the Nummulitic formation of Port des Basques), and B. Cumingit* (a recent 
species from the Philippine Islands), by the existence of the fifth cyclum of septa ; and from 
B. tenuistriata (fossil of the Paris basin), B. desmophyllum® (fossil of the London Clay), 
B. italica® (fossil of the Pliocene deposits of Asti), and B. Bairdiana (a recent species), 
by its general form, and the slight elongation of its calice. The species which it most 
resembles is B. verrucaria, which exists at the present period on the coast of Corsica ; 
but in the latter the columella is less developed, and the arrangement of the septa of the 
last orders is less regular.’ 
Balanophyllia calyculus is common in the Red Crag of Sutton, but has not, to our 
knowledge, been met with in other localities. Mr. Searles Wood considered it as identical 
with some fossil Coral found im the Faluns of Touraine, but the latter are young specimens 
of the Dendrophyllia amica ; they resemble B. calyculus by their epitheca, but are easily 
recognisable by the mode of arrangement of their septa, and their multiplication by 
gemmation when in the adult state.° 
We have examined numerous specimens of this species in the collections of the 
Geological Society of London, of Messrs. Bowerbank and Searles Wood, of the Museum of 
Natural History, and of MM. D’Archiac, Michelin, and Milne Edwards, in Paris.
