MOORE ABXOEMAL SECONDARY DEPOSITS. 485 



greenish crystalline rock of the same age ; 2 feet 6 inches. On the 

 north side of this there has been subsequently let in a band of clay 

 with black siliceous pebbles and Ehaetic bone-bed debris. 



6. Breadth of inclined Carboniferous Limestone, 15 feet. 



7. Irregular bed of clay with Carboniferous Limestone and siliceous 

 pebbles, and fish and other remains of Ehaetic age. 



8. Carboniferous Limestone, 21 feet. 



9. Yein of spar, occasionally enclosing Liassic stones, mottled or 

 stained with oxide of iron, 6 inches. 



10. Carboniferous Limestone, 3 feet. 



11. Vertical vein of Lias, very various in colour (cream-coloured, 

 yeUow, pink, green, or blue), showing by its occasional thinly lami- 

 nated structure that it was in fact very slowly deposited. This en- 

 closes angular fragments of Carboniferous Limestone. In this vein 

 may be found occasional nests of Ehsetic remains mixed with Rhyn- 

 chonella variabilis, Terehratula punctata, and Belphinula nuda, Moore, 

 and a crustacean claw of Liassic age. At the base of the quarry it 

 attains a thickness of 13 feet. 



12. Carboniferous Limestone, 30 feet. 



13. Liassic infilling, having on the south a thin vein of carbonate 

 of iron, 3 inches, next a band of deep-red and yellow conglomerate, 1 

 foot, succeeded by crystallized carbonate of lime 2 feet, and Liassic 

 conglomerate 6 feet : 9 feet 3 inches. 



14. Carboniferous Limestone, 3| feet. 



15. Irregular Liassic infilling, with thin veins of ironstone, 3 feet. 



16. Carboniferous Limestone, 8 feet. 



17. Yein of carbonate of lime, 1 foot. 



18. Carboniferous Limestone, 6 feet. 



19. Vein of carbonate of lime, 3 inches. 



20. Carboniferous Limestone, 3| feet. 



21. Yein of carbonate of lime, 5 inches. 



22. Carboniferous Limestone, 12 feet. 



23. Liassic vein, variegated or red from oxide of iron, 2 feet, 

 having in the centre a vein of spar showing traces of galena. This 

 is followed by another vertical band of yellower limestone, having 

 on its weathered sides multitudes of Pentacrinite stems, the infilling at 

 this point being almost made up of them. On the side of this dyke, 

 30 feet below the surface, I noticed a nest of beautiful univalves 

 mixed up with the Pentacrinites ; and I was fortunate enough to cut 

 out the block containing them, which, although only five inches 

 square, contains forty-four specimens belonging to ten genera, some 

 of the species being identical with forms from the Hierlatz-Schichten, 

 noticed by Dr. Ferdinand Stoliczka, and with others from Fontaine- 

 etoupe-Four. 



24. Yein of crystalline carbonate of lime, 4 feet 4 inches. 



25. Liassic stone, 2 feet 6 inches. 



26. Yein of ferruginous stone, Liassic, 10 inches. 



27. Carboniferous Limestone, 33 feet. 



28. Yein of carbonate of lime &c., 1 foot. 



29. Carboniferous Limestone, 14 feet.
