364 R. F. TOMES ON MADREPORARIA FROM THE LIAS OF 
the genus Chorisastrea. Thecosmilia Martini and T. Michelini are 
omitted from the present list because they do not occur, to the best 
of my belief, either in the White Lias or in the conglomerates of 
Glamorganshire. Of the species which are characterized by a small 
number of very irregularly developed septa and a stunted form, such 
as Thecosmilia Terquemi, T. Brodie, and T'. dentata, but little can 
be said definitely, and it is even possible that they represent only the 
immature state of some species which, by aftergrowth, would assume 
a different form. These present very little affinity with the multi- 
septate St. Cassian and Sutton-Stone species.

Impressions of the calices of a coral occur in the White Lias of 
Warwickshire which I do not hesitate to refer to this species. For 
the purpose of direct comparison, I have taken casts from these im- 
pressions, which, when compared with veritable specimens of T’heco- 
smilia Hornesii from the St. Cassian beds, are so exactly similar as 
to leave no doubt of their specific identity. The two woodcuts (5 
& 6) at p. 68 of Prof. Duncan’s ‘Supplement to the British Fossil 
Corals,’ were, I have no doubt, taken from unfavourable examples 
of such casts, though they are considerably larger than is usual. 
THEcosMILIA RUGOSA, Laube, loc. cit. p. 256, Taf. v. fig. 4. (Pl. XIX. 
fig. 1.) 
Fragments of this species are not rare in the White Lias of 
Warwickshire and the adjoining parts of Worcestershire, but they 
are usually in a very bad state of preservation, and rarely possess 
anything more of the characteristics of the species than is seen in 
the rugose portions of broken-up corallites. One example only 
shows a well-preserved calice. It was taken by me from a quarry 
in an outlier of White Lias at Meer Hill, near Loxley, about two or 
three miles north-east of Stratford-on-Avon, and was very near to 
the bottom of the excavation. This is the position in which I haye 
found all the specimens in this as well as other localities. 
In the Sutton Stone of Sutton and West, the present species is not 
rare; but occurs only in fragments which possess the same pecu- 
liarities as the White-Lias and St. Cassian specimens. 
THECOSMILIA CONFLUENS, Laube, loc. cit. p. 257, Taf. v. fig. 5. 
(PL XT Ms piie. 75) 
Cyathophyllum confluens, Miinst. Beitr. iv. p. 37, tab. ii. fig. 16. 
I have met with a fragment only of this species lying amongst 
the rubbish in the bottom of a quarry of White Lias at Stoneythorpe, 
in Warwickshire. Although partially enclosed by stone, the folia- 
ceous character of its calicular surface is well shown. It differs 
from Laube’s illustration (fig. 5c) only in having the lobes more 
crowded, so that the folds almost overlap each other, and in having 
the septa more distinctly denticulated. 
Amongst the same rubbish was found the specimen of Hemipedina
