COKALS OE THE LIAS OF ENGLAND AND S. WALES.

Similar stunted Thecosmilice have occurred in the same hed at 

 Wilmcote, near Stratford-on-Avon, and they correspond very well 

 with the Thecosmilia Terquemi of Dr. Duncan. 



At Street, Somersetshire, a small Thecosmilia occurs which may 

 perhaps be the same species. It was found by myself in 1860 in the 

 same quarry which su}3plied Dr. Wright with the Isastrcea since de- 

 scribed by Dr. Duncan under the name of Isastrcea l-atimceanclroidea*, 

 and the following section made at the time will show the position of 

 both corals.

The species in this bed corre- 

 spond with those of the Ostrea- 

 bed of other localities. 



I afterwards found the same coral, in the same disjointed condi- 

 tion, in blocks of stone in every respect similar, at a place called 

 Marshall's Elm, near Street. It was probably a small species (if 

 not young examples of the last), none of the fragments exceeding an 

 inch in length, and the third of an inch in the diameter of the calice. 

 The horizontal sections in the stone show the septa very clearly.
