On Two Ovrimrs or Lias AnD Rumtic Bens at KNowLe AND NEAR Woorron 
Wawen ww South Warwicxsutre. By the Rey. P. B. Bropin, F.G.S. 
re chief object of the author in this paper was to describe 
the Liassic Outlier at Copt Heath, where the limestones were 
formerly worked by a shaft long since abandoned. ‘These appa- 
rently belong to the ‘ Saurian beds,’ and the associated shales con- 
tain well-preserved specimens of Ammonites planorbis. Near this 
spot, on the canal-bank, in a very obscure section, some black shales 
may be seen overlying the Red Marl, on the top of which are small 
detached masses of thin-bedded sandstone, of a brown and yellow 
colour, in which impressions of Pullastra arenicola were abundant— 
a shell which always occurs low down in the series, in connection 
with the ‘ bone-bed,’ and seems to have a very limited range. These 
representatives of the Rhetic beds had not been previously noticed 
in Warwickshire, and this is their extreme northern limit in that 
county; but they have been detected further north in Staffordshire, 
by Mr. Howell of the Geological Survey. The paper also gave an 
account of some other outliers in Warwickshire, where the lowest 
beds of the Lias are exposed, including the ‘Insect-beds,’ with 
numerous remains of Insects, and lower strata containing the cha- 
racteristic E’stherca and Pecten Valoniensis. In all these cases, they 
can be readily identified with the basement-beds (Rhetic) over- 
lying the Red Marl in Gloucestershire, though much reduced in 
thickness ; and, though no actual bone-bed has as yet been seen in 
situ, it may possibly be present in some places which have escaped 
a close examination.

ee Paleozoic Crustacea included in this family have already 
formed the subject of papers read before the Association by 
Messrs. Page and Salter, and were first discovered in America by 
De Kay in 1826. The only separate memoir, however, is that in the 
Geological Survey Memoirs, 1859, by Messrs. Huxley and Salter. 
Other descriptions are to be found in the Quart. Journ. Geol. Soc., 
Hall’s Paleontology of New York, &c. During the past five years 
numerous additional specimens have been discovered, better illus- 
trating those already partially known, and affording many new forms. 
The author proposed the following classification of the genera and 
species, and gave descriptions and figures of the principal British 
forms :— / 
. 1. Euryptervs, De Kay. 
Eurypterus Scouleri, Hibbert; Lower Carboniferous Rocks, Fifeshire. 
E. mammatus, Salter; Coal-measures, Manchester. 
Arthropleura (Kurypterus) ferox, Sater; Coal-measures, Coalbrook-dale.
