CORALS OF THE LIAS OF ENGLAND AND S. WALES. 185 



Another and larger specimen was taken by me from the Bishopton- 

 Hill cutting on the Stratford and Hatton Railway, which passed 

 through the lower part of the Lima-beds. Its precise position I am 

 unable to give. 



The calices of this larger specimen being in a better state of pre- 

 servation than those of the specimen described by Dr. Duncan, enable 

 me to add the following : — ■ 



The corallum would be symmetrically balloon-shaped, excepting 

 for a lobe at its base. Height 9 inches, base attached to a mass of 

 oysters (Ostrea irregularis). Calices somewhat larger than in the 

 type specimen. "Walls thin, but their extreme margins thickened 

 and smooth ; and this thickened part passes down many of the septa, 

 and spreads out where they meet in the centre and are fused 

 together, forming an irregularly shaped prominence, which is as 

 high in some of the calices as the walls themselves. I think this 

 thickening and filling up of the calices is merely the result of excess 

 of endothecal structure, which is everywhere visible in the inter - 

 septal loculi.

This species, although assigned by Dr. Duncan to the zone of 

 Ammonites Bucklandi, is, I believe, confined to that of A. angulatus. 

 A considerable number of specimens were at one time obtained from 

 a brickyard at Chadbury, near Evesham ; and this excavation lay in 

 the very heart of the latter zone. It was a very fossiliferous deposit 

 of dark blue clay, in which the organic remains were well preserved. 

 From it I took most beautiful and large examples of Oardinia ovalis, 

 and typical specimens of Ammonites angulatus. Chadbury Hill, in 

 contiguity to the brickyard, is capped with the so-called Lima-heds, 

 as at Grafton and Bin ton.

My friend the Rev. P. B. Brodie took this coral from a cutting in 

 the Oxford, Y/orcester, and Wolverhampton Railway, near to Flad- 

 bury, where the lime passes through the same bed as that in which 

 the last species was found. Mr. Brodie, however, informs me that, 

 so far as he remembers, no fossil was found associated with it.

 France, p. 127, pi. xvii. figs. 7, 8. 



I have collected this species in abundance at St. Bride's, near Bridg- 

 end, but am quite unable to assign it a definite place in the Lias there. 

 In 1811 Mr. Strickland gave an account of the cuttings of the 

 Birmingham and Gloucester Railway in the ' Transactions of the 

 Geological Society.'" At page 551 he mentions " a Caryojphyllcea " 

 as occurring about a mile south of Norton, near Worcester ; and he 

 adds, " which is remarkable from the general scarcity of corals in
