occasionally procured. Overlying the Pea grit is a band of 
white marl resembling chalk made up of corals, evidently having 
formed acoral reef in the ancient Jurassic sea. Several good 
examples of Montlivaltia, Latomeandra Flemingii, Thamnastrea 
Defranciana and Mettensis were picked up. As this coral bed is 
overlaid by the freestone and contains some of the species noticed 
in the Oolite Marl besides shells, it is evidently a continuation of 
that stratum, though more loaded with corals, but not so thick as 
the marl at Leckhampton, the reduction in bulk being fully 
accounted for by the increased thickness of the Pisolite.* Mr. 
Brodie drew attention to the basement beds, here loaded with 
Belemnites and remnants of fishes, chiefly minute Hybodonts. 
Returning home by Leckhampton, a good opportunity was 
afforded of noting the remarkable fault of Shurdington hill on the 
left, which may be traced for several miles from east to west. 
At a point hereabouts, the freestones on one side of the line of 
fault have been thrown down toa level with the passage beds on 
the other, as much as 90 feet. Another fault also traverses the 
southern base of Crickley hill which has been notieed by Mr. 
Hull in his excellent monograph of the Cotswolds in the Memoirs 
of the Geological Survey. 
The Rey. W. Norwood has kindly furnished the following list 
of Plants, collected by Mr. Notcott and the other Botanists of 
the party :—Asperula cynanchica, Thymus Cameedsys, Ophrys 
apifera, Herminium monarchis, Orchis ustulata, Artragalus 
hypaglottis, Lithospersmum officinale, Blyssmus compressus, 
Torilis nodosa, Hyoscyamus inger, Erodium cicutarium (very rare 
in this district), Vicia tetrasperma. 
*At Crickley above the Pea grit is a thick band, about three feet of marl almost 
entirely made up of cota oan the abeence chy frosotons mote, rors and shally 
freestone, but the pisolite is very thick and may well account for the absence of these 
freestones ; and this marl is no doubt the correct representative of the Oolite marl 
there and at Leckhampton.
