178 BRITISH FOSSIL CORALS. 
but we have been enabled to ascertain that this last-mentioned character exists in all true 
Amplexus, and that no other organic peculiarity distinguish these from the typical form of 
Cyathopsis; we have, therefore, not adopted the new generical name proposed by 
M. D’Orbigny and employed by Professor M‘Coy. We must also remark that the latter 
author places in the genus Cyathopsis, together with this Lophophyllum, two species of 
true Zaphrentis, and we do not well understand on what grounds he has proceeded in so 
doing, or how to interpret the apparent contradictory statements relative to the characters 
of Cyathopsis, when Professor M‘Coy, after having said “ These corals differ from Caninia 
(or Zaphrentis) in wanting the outer perithecal small vesicular area or lining of the walls,” 
adds that they differ “from Calophyllum, (which I only know by name,) by the vesicular 
edge of the transverse plates between the lamellae at the walls,” &.

Corallum very long, sub-cylindrical, curved, very slightly compressed, and bearing 
strong circular swellings placed at about 2 or 3 lines apart. Cadice somewhat oval; its 
two diameters as 100:130, and its long diameter corresponding to the curve of the 
corallum. Septa very thin, very closely set, almost equal, numerous (about 150), straight 
or slightly bent, and reaching to the centre of the calice. A vertical section shows that 
the tabule are very small and distant; the vesicular dissepiments very small and almost 
vertical, and the septa well developed. Height of the cora//um, 7 inches; great diameter 
of the calice 2 inches, small diameter 1: inch. 
Found at Frome, Somersetshire; Tyn-y-castle, Clifton, and Mold. Professor M‘Coy 
mentions its existence at Arnside, Kendal, and Lisardrea, Boyle, Roscommon. 
Specimens are in the Collections of the Bristol Museum, the Museum of Practical 
Geology, the Geological Society, the Cambridge Museum, Mr. Bowerbank, Mr. Stokes, and 
the Museum of Paris.
