160 LIAS OF ENGLAND AND WALES : 
The beds were measured, in 1873, by the Rev. P. B. Brodie and 
Mr. T. Beesley, and details (differing in some particulars) have 
been published by them. The fossils indicate that the lower 
portion of the zone of Ammonites Bucklandi, and the zone of A. 
antjulatus, are represented by the limestone-series. The Insect 
Limestones do not appear, the limestones of this division ami of 
the zone of A. planorbis generally, being represented, so far as can 
be observed, by clay, which is a very unusual feature. 
The following fossils have been obtained from the railway-cutting 
at Harbury : 
Ichthyosaurus. 
Plesiosaurus. 
Acrodus. 
Ammonites angulatus. 
Bucklandi. 
Conybearei. 
Johnstoni. 
Nautilus striatus. 
Avicula inaequivalvis. 
Gryphaea arcuata. 
Lima Hermann). 
gigantea. 
Ostrea irregularis. 
Ostrea liassica. 
Pecten lunularis. 
pradoanus. 
Perna. 
Pinna. 
Pholadomya glabra. 
Unicardium cardioides. 
Rhynchonella calcicosta. 
plicatissima. 
Cidaris Edvvardsi. 
Extracrinus briareus. 
Pentacrinus tuberculatus. 
The limestones (zones of Am. angulatus and A. Bucklandi) have 
been worked for lime at Southam, Stockton,* Long Itchington, 
Dray cote near Bourton-upon-Dunsmore, and Stretton-upon- 
Dunsmore. A specimen of Hemipedina Tomesi (in the Warwick 
Museum) was obtained from a rey and rather compact limestone 
at Long Itchington. This is indicative of the basement-beds of 
the Lower Lias. 
The clays above the stone-beds have been worked for brick- 
making south-east of Southam, and also at the base of Napton 
Hill, to the east of Southam, where the beds belong to the zone of 
A. capricornus. 
The boundaries between the Keuper Marls, Rhretic Beds, and 
Lower Lias, can be readily determined as far as the neighbour- 
hood of Stretton-on-Dunsmore ; but further north the beds are 
much obscured by Drift.t 
The railway-cutting south of Fenny Compton railway -station, 
has shown an excellent section of the beds from the base of the 
zone of Ammonites Hcnleyi> through that of A. Jarnesoni and A. 
Ibex, into that of A. armatus. These beds and their fossil contents, 
have been very fully described by Mr. Thomas Beesley, and as the 
section is now by no means so clear as it was, I append his 
account, merely observing that I visited the section in 1887 under 
his guidance. The following is the section by Mr. BeesleyJ :
