R. F. TOMES ON THE STEATIGEArHY OF THE 



The walls and septa are very thin ; and the latter are not more than 

 about twenty in number, and they none of them reach to the middle of 

 the calice. These sections appear to be those of a coral quite as much 

 like Cladophyllia as Thecosmilia ; but outwardly the fragments much 

 resemble fig. 2 of T. Martini, given by Terquem and Piette at 

 pi. xxii.

 no. 2, p. 65, pi. xv. figs. 18, 19 (1868). 

 In a stone-quarry near to Temple Grafton, Warwickshire, I met 

 with a portion of an Lsastrma, which, from the form of the calices, 

 and the abundance of its marginal gemmation, may probably be 

 referred to this species. The following section will show its position 

 in the quarry : — 



t's Quarry, Grafton. 



Surface soil. 



Dark grey stratified but not 

 laminated shale. 



"Rusty bed," a thin band of 

 dark grey stony shale with a 

 ragged fracture, often pyritic, 

 and decomposed into rust, very 

 persistent in the district. 



Laminated beds, stone and 

 shale, succeeded below by the 

 " Griesley-bed, Ostrea-bed, &c, 

 depth not taken. 



Ammonites Johnstoni, Nauti- 

 lus, Lima gigantea, L. anti- 

 quota, Cardinia ovalis, Area, 

 Ostrea irregularis, a small 

 smooth Pecten, Astarte, spines 

 and plates of Cidaris Edwardsi, 



IsASTRiEA LATIJLEANDROIDEA ?, 



Dune. 



Saurians, Insects, Ammonites 

 Johnstoni. 



An Isastrcea has also occurred in a quarry at Binton, very near to, 

 if not in the " rusty bed." It had been taken with the clay by the 

 workmen, and used to bank up a burning lime-kiln ; and when I saw 

 it fire and water had reduced it to lime.

The quarry at Temple Grafton, of which I have given the section, 

 is situated half a mile south-west of a low hill or ridge, on the top 

 of which the plough brings up the beds of nodular stone known in 

 Warwickshire as the Lima-beds, and containing the Lima gigantea 

 in abundance. The bottom beds crop out halfway up the hill ; and 

 in them Cardinia ovalis is plentiful, and examples of Ammonites 

 angidatus by no means rare. Immediately under this bed, in the 

 clay, I met with the type specimen, just below a plantation called 

 " the Long Coppice."
