oie R. F. TOMES ON MADREPORARIA FROM THE LIAS OF 
respect to the coral from the Greensand of Haldon which has been 
made the type of the genus Haldonia by Prof. Duncan. 
? STYLASTRZA, sp. 
A specimen in my own collection, consisting of a few calices only, 
bears a very strong resemblance to a Stylina. It was taken from 
the Brocastle conglomerate by my late friend Mr. J. W. Kirshaw, 
on the occasion of a visit to that locality made by him and myself 
in company with the late Mr. Moore. 
Genus CratHocentra, Duncan. 
Phyllocenia, Laube (not Edwards & Haime). 
To this genus, which was created by Prof. Duncan, in 1867, for 
some corals from the Liassic conglomerate of South Wales, and for 
one species from the Amm.-angulatus-zone of the Lower Lias of Wor- 
cestershire, must, I believe, be referred the Phyllocenia of Laube. 
Although in the figure given by him of Phyllocenia decipiens the 
septa appear to have entire edges, and are therefore consistent with 
those of the Tertiary and Cretaceous Phyllocenice, yet in the letter- 
press they are distinctly mentioned as being serrated. This alone 
supplies sufficient grounds for the removal of the species from the 
genus Phyllocenia. The greater part of the Cyathoceenie from the 
Glamorganshire Lias have lost their septal denticulations ; and that 
the specimen from which Laube’s Phylloceniadecipiens was taken had 
similarly suffered will become exceedingly probable if we compare the 
figures of that species with Prof. Duncan’s of Cyathocenia costata*. 
CysTHoceNtTA DECIPIENS, Laube,sp. (Plate XIX. fig. 3.) 
Phylloceenia decipiens, Laube, loc. cit. p. 264, Taf. vi. fig. 1. 
My knowledge of this as a Sutton-Stone fossil is confined to the 
examination of a single specimen taken by myself from one of the 
small excavations between Sutton and West. The septa and coste 
of this example are wholly without denticulations. As will be seen 
on reference to the figure here given, these parts, as well as the 
general conformation of the calices, very closely resemble those given 
by Laube for this species. 
CyaTHOCENIA DENDROIDEA, Duncan, loc. cit. p. 27, pl. ix. figs. 6, 7, 
8, 9. 
Fragments of this species are not rare at Brocastle, from which 
place I have received several specimens. 
CyarsoceniA incrustaNs, Duncan, loc. cit. p. 28, pl. iv. figs. 1, 2. 
The specimen from which Prof. Duncan’s illustration of this 
species was taken was found incrusting an oyster; and the only 
other one I have seen, which was taken by me from the Sutton 
Stone, is similarly incrusting a shell of the same species.
