170 LIAS OF ENGLAND AND WALES: 
arcuata, &c. Beds of this nature, noted by Prof, Judd, were 
reached in a deep well in Stapleford Park.* 
Blue pyritic clays with occasional bands of limestone, yielding 
Ammonites semicostatus, &c. were opened up in cuttings near 
Thurnby, and Ingersby or Scraptoft tunnel, east of Leicester.t 
Still higher beds of pyritic shale with nodules of limestone, 
bands of shelly limestone, and ferruginous concretions, belonging 
to the zone of A. oxynotus were exposed by the tunnel between 
Grimston and Old Dalby, and in a brickyard between Houghton- 
on-the-Hill and Billesdon.J 
At the potteries at Loseby and in the railway-cuttings near 
Loseby station, clays and shales with septaria and nodules of iron- 
stone were exposed to a depth of about 25 feet. Towards the 
middle of the section at the potteries, there was a layer of grey 
sandy rock. The following fossils were obtained by Prof. Judd : 
Saurian vertebrae. Cardinia. 
Ammonites armatus, abundant. Gryphasa cymbium. 
gagateus (Coynarti). 
Loscombei, sometimes 
obliquata. 
Hippopodium ponderosum, 
very large, and the specimens | large rugose variety, 
covered with Ostrea, Serpula. Lima Hermanni. 
&c. 
Nautilus truncatus. 
Belemnites acutus. 
Avicula. 
Modiola scalprum. 
Arcomya elongata. 
Pholadomya ambigua. 
Pentacrinus. 
The beds were grouped by Prof. Judd in the zone of A. arma- 
tus. The occurrence of A. Loscombei is however suggestive of 
higher beds ; and Mr. St rang way 3 is of opinion that they include 
beds belonging to the zone of A. capricernus. 
Beds belonging to the zones of Ammonites armatus, A. Jamesoni, 
and A. Ibex have been noted in the railway-cuttings near Freeby 
and Saxby, and again near Little and Great Dalby. They con- 
sist of sandy clay and pyritous shales, with septaria, ferruginous 
nodules, and occasionally thin bands of impure limestone, and 
pieces of jet. Beds of this character were shown in a cutting of 
the Bourn and Saxby railway, east of Saxby, where they were 
apparently faulted against the Marlstone. 
Specimens indicating the zones of A. Jamesoni and A. capri- 
cornus were obtained by Prof. Judd from openings in the Lower 
Lias clays of Stapleford Park : he enumerates the following: 
Ammonites brevispina, rare. 
capricornus, rare. 
Jamesoni. 
latsecosta, abundant. 
normanianus, rare. 
trivialis. 
Belemnites clavatus. 
elegans. 
Trochus. 
Cypricardia cucullata. 
Gryphsea cymbium. 
Limea acuticosta. 
Lima Hermanni. 
Plica-tula spinosa. 
Unicardium cardioides.
