Transition-bed. 
A. G.—This bed only indifferently represented, and 
where present it is hard and the fossils 
poor. Ammonites acutus. 
Bock-bed. 
B. 7.—Hard stone, very black in fissures, blue 
hearted, pebbles and concretions rather 
plentiful. Pecten dentatus , Terebratulce , &c. 
About 2ft. 4 0 
Very ferruginous bed, highly fossiliferous, 
fossils obtained best from top. Modiola, &c. 
About 1ft. 
Light coloured and soft rock, quite oolitic in 
places, containing :— Cardium truncatum , 
Pecten liasinus, Pholadomya, dec. About 1ft. 
I. 8.—Dark blue micaceous clay, getting more sandy 
J. towards the bottom 
K. A band of liiglily-fossiliferous nodules about 
lft. from top, containing:— A. margaritatus. 
Other fossils, chiefly from clay :—Ostreci 
sportella, Ostrea cymbium, Pecten cequivalvis , 
Plicatula spinosa, Aviculci incequctlvis , Cardinia 
antiqua , Pleuromya costata 
L. 9.—Hard bed, seems to be made up of highly-fossil- 
iferous nodules. This bed yielded a good 
supply of water under pressure, and so was 
only just broken into. From the single 
nodule obtained, the following fossils were 
extracted :—Turbo cyclostoma , Pecten aquivalvis, 
Pecten liasinus (very large), Limea cicuticosta , 
Plicatula spinosa , Avicula incequivalvis, Cardinia 
Icevis , Cardinia antiqua, Protocardium truncatum . 
The matrix resembles that of Bed “L” at Gayton and 
elsewhere.
