b44 H. WOODWARD ON EOCENE CRUSTACEA 
There can be little doubt that the beds exposed in the cliff-sections 
at Gurnet and Thorness Bays belong to the Bembridge series, and 
that the hard band, from which the insect-remains and Crustacea 
have been obtained, belongs to the lowest part of that series. 
The beds dip to the 8.W., so that in about half a mile the lower 
bed of limestone is just on the line of high water; and about 200 
yards further west it forms a reef known as “Stuckler’s Ledge,” 
which is the eastern point of Thorness Bay. 
Within Thorness Bay the beds dip more rapidly to the south, till at 
400 yards distance from the ledge the shale with fossils dips down 
to the beach and forms a small reef. 
As no fossils, save those already recorded, had been noticed by 
Messrs. Forbes and Bristow, great was my delight to find in Mr. 
A’Court-Smith’s collection, the result of 20 years’ patient collecting 
in his leisure hours, abundant remains of insects evidencing the 
presence of more than twenty genera, representing Coleoptera, 
Hymenoptera, Lepidoptera, Diptera, Neuroptera, Orthoptera, and 
Hemiptera, and one representative of the Arachnida. 
Mr. A’Court-Smith accounts for the abundance of remains of 
insects in particular blocks by the theory that they were (after 
being drowned) left by eddies in pockets, much in the same way as 
we find organic remains in streams, lakes, and along the coast at 
the present day. 
For the determination of the insect-remains, so far, | am indebted 
to my experienced friend and colleague, the late Frederick Smith, 
Esq., Assistant-Keeper of the Zoological Department, British 
Museum. Possibly some more adventurous paleo-entomologist may 
make a more rigorous study of them, and give to some at least of the 
more perfect remains generic and specific determinations.
