so feebly represented, the entire thickness, which has not 
yet been accurately ascertained, is much less. The Lima 
gigantea is a very characteristic and wide-spread species, 
and marks this division of the lower Lias everywhere 
throughout its course through the British Isles. The 
important series of strata which succeed these are not 
seen at Harbury, but are well exposed, and largely quarried 
at Messrs. Greaves and Bull’s quarries at Wilmcote, and 
at other places west of Stratford, as at Binton, Grafton, 
and Bidford, and at the remarkable outlier of Brown’s 
Wood, near Henley-in-Arden, and at another (Copt Heath) 
near Knowle,* neither of which are now worked, these two 
last are of special interest, because they shew the lowest 
beds of Lias in connection with and passing into the 
Rhetics resting immediately upon the New Red Marl, or 
highest part of the New Red Sandstone rarely seen in 
conjunction in this county. The general character of 
these lower Lias beds will be best understood by the fol- 
lowing section at Wilmcote, which, down to No. 30, fairly 
represent the rest :— 
%* At Brown’s and Stooper’s Wood, near Wootton-Wawen, the Rhetic series con- 
tain many characteristic fossils in certain calcareous bands, e. g., Pecten valonensis, 
Cardium Rheticum Pleurophorus elongatus, Avicula contorta, and others, and if 
worked would no doubt yield many more species. At Copt Heath there is a stratum 
of yellow, micaceous sandstone, full of Pullastra arenicola, which, though as usuaj 
in the form of casts, are sharp and well defined. I also lately detected pieces of stone 
which, though without any traces of bones or teeth, evidently belong to the true 
‘bone bed.’ Traces of the ‘bone bed’ are stated by Mr. Lucy to occur in the Gravel 
Pit at Snitterfield, which proves its former existence in situ in this county, as it was 
probably brought from no great distance by the same agency which conveyed the other 
Liassic fossils rocognised in the drift there.
