NOTES ON" THK LIAS IN THE NEIGHBOFRHOOD OF EADSTOCK. 169 



authority. One only regrets that he has not been able to give 

 more details concerning the Radstock beds in the two Papers^ in 

 in which he touches on the subject. 



By way of description, then, of the Lias in this district, I 

 propose to bring forward sections observed in quarries at different 

 parts, as much as possible working out the fauna of each bed by 

 trac'ng it from quarry to quarry, and noting every fossil found in 

 situ. We neglect, for the most part, fossils of which we do not 

 know the precise parent bed, our object not being to note a long 

 list, but to determine the exact bed in which certain well-known 

 fossils occur. Much fuller lists of fos-^ils will be found in what 

 Mr. Moore has written. 



Few anl imperfect as our observations have been, we have been 

 able to determine something of the range of Ammonites and 

 Brachiopoda, which was the main object: not that I can pretend 

 to have advanced knowledge under this head beyond a point 

 known to Mr. Moore, but our observations are, at any rate, 

 independent. 



In a quarry scarcely out of the town of Radstock, we have the 

 following section : — 



The lower part of this series, from the " Sun-bed " downwards, 

 is *' White Lias." As we found scarcely any fossils in situ we 

 have not given measurements in detail, either here or in following 

 sections, but White Lias fossils are to be found on the refuse 

 heaps— we may mention Monotis fallax in this case. The " Sun- 

 bed," with its level shelf, is found in all cases where the White 

 Lias is seen, so far as I know. The quarry is not worked down 

 to the Khsetic shales, which cannot be far below.
