 the former and Polymorphines in the latter. The chief species 

 are : —

A short distance further on we meet with another larger pit, in 

 which is the following section : —

10. Blue clay in layers, 10 ft. 8 in., to 1

In a part of the quarry opened at a lower level are seen some 

 oyster-bands {Ostrea irregularis, Mstr,), such as are seen better in 

 the next pii. 



The beds No. 1 and No. 3 of this pit evidently correspond to 

 No. 2 and No. 4 of pit 1 ; and if they have yielded fewer fossils, it 

 is probably only from being less exposed ; the lower beds are decidedly 

 less fossiliferous. In all the beds here Am. Johnstoni (Sow.) is the 

 chracteristic Ammonite ; and I have not detected the true A.planorhis 

 in the clay beds. They are, however, full of Foraminifera and En- 

 tomostraca. The varieties are too numerous to be fully recorded 

 here, and must await further study, with other Liassic representa- 

 tives. Their chief forms, however, are : —
