Sections of rocks (Figs. 1 to 4) from the Raised Beach at Etel, Brittany ; prepared 
and described by Mr. R. F. Gwinnell, B.Sc. The photomicrographs were prepared 
by Dr. H. H. Arnold-Bemrose, M.A., F.G.S., under crossed nicols.

By lL. Ricuarpson, F.R.S.E., F.G.8. 
fF\HOSE who are acquainted with the detailed zoning of the Upper 
Lias and Inferior Oolite of the Cotteswold Hills have long 
desired to know the precise date of the Upper-Lias deposit at Leck- 
hampton Hill, Cheltenham, upon which the Inferior Oolite rests. 
At last the desired-for information is to hand. The Inferior Oolite 
at Leckhampton Hill rests directly upon the Variabilis-Beds of the 
Upper Lias. 
It has, of course, long been known that there is no Cephalopod- 
Bed, like that so well known in the neighbourhood of Dursley, at 
Leckhampton Hill. All the evidence available tends to show that 
the Sevssum-Beds rest directly upon the Variabilis-Beds. That would 
mean that the Opaliniforme-, Aalensis-, Mooret-, Dumortieria-, Dis- 
pansum-, Struckmanni-, Pedicum-, and Striatulum-Beds were absent 
from Leckhampton Hill, and that there is a considerable non-sequence 
there between the Inferior Oolite and Upper Lias. As regards the 
Cotteswold Sands alone, ‘‘ there is a loss of about 140 feet from Coaley 
Bs to Leckhampton Hill” (S. S. Buckman, in litt., November 11, 
1909 
Unfortunately, the actual junction of the Oolite and Lias could 
not be investigated in the deep well from which the fossils indicative
