 sfoni, Lima imnctata, L. demfa, L. tuberculata, L. giganlea, 

 L. aciiticostafa, L. dicplum, L. subduplicata, L. Terquemi, 

 Pholodomj/a prima, F. glahrcu Pecten calvus, P. textorius, 

 P. Suttone7isis, P. quadricosfatns, Perna infraliassina, P. 

 species, PUnromya unioides, P. Galathea, P. liassina, Uni- 

 cardia cardioides, Cardinia Lisferi, Ceromya gibbosa, Os- 

 trea liassica, 0. irregularis, Terqucmia arietis, T. Heberfi, 

 Pli^ahda intusstriata, Mt/tdus minimus, M. Hillanus, casts 

 of a s^ecieso(Gerviliia,Chc7nnitzia,sip., Axinus,&^., Astarte 

 consobrina, A. thalassina, and Cidaris EdwardsL Near 

 the bottom of this bed is the bone-bed of this series, about 

 4 inches thick. It contains scales of Pholidophorus, teeth 

 of Ht/bodus, scales of Gi/rolepis temiistriatus, and G. Al- 

 berti, small coprolites of fish, and Plicatula intusstriata. 

 The scales are mostly fragmentary and badly defined. A 

 Lima, wliich I believe to be L. punctata, is the most cha- 

 racteristic shell of this bed. 



10. A second Oyster-bed, abounding in Ostrea liassica, and 



with a few specimens of Ammonites Johnstoni q g 



11. Clay with Monotis dccussata, Ostrea liassica, Perna infra- 

 liassina, Pleuromya unioides, and Cardium Philippianum. 1 to 3 



12. Laminated argillaceous limestone, sometimes almost en- 

 tirely composed of Mytilus minimus, Modiola Hillana, 

 Cardinia Listeri, Pholadomya, sp., and casts of Littorina. 



13. Soft sandstone containing Chondrites liassinus with 

 Cypris liassica, Cardium Philippianum, Cuculloea Hettan- 



giensis, Pleuromya, sp., and Pecten vimineus. 



14. Indurated dark -grey clay with crystals of sulphate of 

 strontia and carbonate of lime. 



15. Gotham marble. 



16. Keuper marl ; on the surface of tliis stratum the author 

 found a single specimen of Pecten {Valoniensis'}), and 

 fragments of bones of Ichthyosaurus and Plesiosaurus. 



II. Quarry in afield about 100 yards from No. I. 



1 . Vegetable soil 2 



2. Argillaceous loam 10 to 1 2 



3. Sandy limestone passing into blue marl, the latter yielding 

 Lima gigantea, Pholadomya glabra, Ehynchonella plicatis- 



sima, and spines of Cidaris Edwardsi 9 to 1 



4. Dark-blue compact limestone containing Ammonites angu- 

 latus, Cidaris Edwardsi, Littorina semiornata, Pecten calvus, 

 Gryph(Ba, species, Ehynchonella variabilis, Terebratula 



perforata, Ostrea irregularis, Pentacrinus Fisheri, Mytilus 



minimum, Modiola Hillana, and fish-scales 1 Q 



5. Blue Limestone, alternating with clay, and containing 

 Lima gigantea. Ammonites planorbis, A. Johnstoni, Lima 

 punctata, L. tuberctdata, L. acuticostata, L. succincta, L. 

 exaltata, Pecten Suttonensis, P. quadricostatus, Pleuromya 

 unioides, P. Galathea, Ceromya gibbosa, Plicatula, species, 

 Terebratida perforata, Hemipedium Bechii, Astarte conso- 

 brina., fish-scales and traces of Saurian bones. 6 q 



6. The Oyster-bed, which is separated from No. 5 by a nar- 

 row belt of blue clay ; it contains Ostrea liassica in great 

 numbers. 



7. Conglomerate, containing the same fossils as bed No. 8 in
