The species marked with an asterisk in the above list are found 

 likewise in the Inferior Oolite ; but the specimens from the Sands 

 are nearly all dwarfed forms of the species, and lead one to the con- 

 clusion that they lived under conditions unfavourable to their deve- 

 lopment. The stinted growth of the stationary Conchifera forms 

 a striking contrast with the size and number of the Cephalopoda 

 interred with them in the same bed ; in fact the dawning existence 

 of these Conchifera appears to have been a struggle for life, whilst 

 the conditions of the closing scene of the Belemnites, Nautili, and 

 falciferous Ammonites, were favourable to their continuance in time, 

 but abruptly brought to a termination by some great physical change 

 which took place about the commencement of the deposition of the 

 oolitic formations. 



Section V. — At Wotton-under-Edge, near Bradley Turnpike, 

 Gloucestershire"^ . Fig. 3. 



The lower beds in this section are almost a repetition of those at 

 Frocester Hill ; but the relations of the Cephalopoda-bed to the In- 

 ferior Oolite, Fuller's Earth, and Great Oolite are so admirably ex- 

 hibited in this locality, that I cannot omit a brief description of them. 

 I am indebted to my friend Professor Ramsay for the accompany- 

 ing diagram, which shows the succession of the strata between Sy- 

 monds-Hall Hill and Wotton-under-Edge. The hill is capped by 

 the Great Oolite; beneath this is the Fuller's Earth, here attaining 

 a considerable thickness, and overlying the
