158 LTAS OF ENGLAND AND WALES: 
During the construction of the railway-tunnel at Chipping 
Norton, many fine fossils were obtained by Mr. James Windoes 
of that town, from the zones of Ammonites capricornus and A. 
margaritatus. Among those obtained from the zone of A. capri- 
cornus, were the following : 
Ammonites capricornus. 
Davcei. 
Henleyi. 
fimbriatus. 
Belemnites elongatus. 
vulgaris. 
Amberleya imbricata. 
Avicula inasquivalvis. 
Cypricardia intermedia. 
Goniomya hybrida. 
Gresslya. 
Hippopodium ponderosum 
(smooth var.). 
Inoceramus ventricosus. 
Modiola scalp rum. 
Pleuromya costata. 
Pholadomya ambigua. 
The specimens of Cypricardia intermedia (a form that ap- 
proaches very near to C. cucullata) were exceptionally well 
preserved, the finer and larger specimens coming from the zone 
of A. margaritatus. In a long list of fossils from the Lias of this 
locality, Mr. Beesley* lias not separated the species procured from 
the two zones, because the fossils were mainly collected from the 
material brought up from the shafts, or carried out at the mouths 
of the tunnel. Mr. Windoes obtained a portion of Ammonites 
Henleyi belonging to a specimen 18 inches in diameter. 
The observations of Mr. F. A. Bather furnish evidence of the 
zone of Ammonites capricornus near Fawler.f At this locality 
blue clay with hard nodules and a few septaria was proved, by a 
Coring, to a depth of 120 feet. In the upper part of this clay 
A. margaritatus was found, and slightly below, A. capricornus. 
Beds with Amm. capricornus, &c. were proved in a boring at 
Burfbrd Signett, at depths of from 270 to 300 feet from the 
surface. The total thickness of the Lower Lias proved to be 
about 450 feet, and that of the Middle Lias nearly 100 feet ; 
the thickness of the former being less than one half of that at 
Chipping Campden. Limestones are not very prominently de- 
veloped at the base of the formation, for the record of the boring 
gives clay with occasional bands of limestone to near the bottom 
of the Lias. J 
The cutting of the Great Western Railway near Charlbury, 
yielded Ammonites planicosta and Pleurotomaria anglica\ while 
at Ascott-under-Wychwood " the skeleton of an Ichthyosaurus 
was found." Here, according to Prof. Hull, the beds " consist of
