144 LIAS Or ENGLAND ASD WALES: 
Beds on much the same horizon, together with higher strata, 
occur at Pilford, near Leckhampton, where the brickyard showed 
blue and brown loamy clays, with a band of ironstone nodules, 
yielding Ammonites, Avicula incsquivalvis, Pecten cequivalvis f 
Pholadomya, and Pleuromya. These beds rest on blue pyritic 
and micaceous sandy clays, with iridescent fossils. Prof. Tate 
records from this locality, Ammonites armatus, A. Jamesoni f 
A. Valdani, A. Ibex, A. Henleyi, Belernnites clavatus, Inoceramus 
ventricosus, Waldheimia numismalis, &c.* ; the fauna resembling 
that from Aston Magna, and including the zones of A. Jamcsoni 
and A. Henleyi. 
From the brickyard east of Cheltenham, I obtained Ammonites 
Jamesoni, A. Loscombei, A. striatus, A. Valdani, Belemnites, and 
Inoceramus ventricosus ; fossils that indicate portions of the same 
zones as occur at Pilford. 
Ammonites striatus (near to A. Henleyi) has been found abun- 
dantly in pits near Charlton Kings, as mentioned by Murchison, 
who originally figured the species under the name of A. cheltiensis* 
It occurs also in the brickyard north-east of Shackels Pike, and 
near Hewlets.f In this neigbourhood rugose forms of Hippopo- 
dium ponderosum have been found, together with A. Henleyi or A. 
striatus. 
Prof. Hull notes the occurrence of ferruginous concretionary 
nodules, so characteristic of the upper beds of the Lower Lias, in 
brickyards at Hewlets Hill and in the lane leading from Heartly 
Hill to Charlton Kings. J 
Teickesbury to Per shore. 
The basement-beds of the Lower Lias have been exposed in 
quarries in the neighbourhood of Tewkesbury, where the lime- 
stones are more prominently developed than further south in the 
Vale of Gloucester. 
Here we come into the region of the " Insect Limestones " of 
the Rev. P. B. Brodie, a term applied to certain bands of lime- 
stone that occur at or near the base of the Lower Lias or the top 
of the Rhastic Beds, on the borders of Gloucestershire, Worcester- 
shire, and Warwickshire. 
The characteristic beds, which are now best shown between 
Evesham and Wilmcote, are banded limestones that split up more 
or less readily along the planes of stratification, and frequently 
display remains of Insects (chiefly Coleoptera), and Crustacea 
belonging to the genus Eryon, &c. These beds clearly occur in 
the Lower Lias (zone of Ammonites planorbis), and usually above
