(C) Two New Sections in tlie Middle and Upper Lias at 

 Barrington^ near Ilminster, Somerset. (J. P. & A.T. 

 Notes in 1: rackets by S. S. B.) 



During tlio year 1920 a C|imn'Y was opened in a field on the west 

 side of tlie cross-roads between Barrington and Stocklinch, and 

 650 yards sontli-west of Barrington Church. In the excavation, 

 which was carried down to the base of the Marlstones, aboat 

 14 feet of Upper Lias clay and limestones are exjDOsed. An 

 abstract of these beds, numbered in ascending order from 1 to 26,. 

 is set forth in the appended section (p. 451). Fuller details await 

 a critical examination of the annnonites. 



In the same year a smaller quany was opened on the west side 

 of Shelway Lane, Barrington ; it shows a similar sequence of 

 Middle and Uj^per deposits on the eastern side of the pit. Beds 

 1-26 of the Upper Lias can again be seen ; but in the roadside 

 above the quarry and in the bank above the adit on the east side 

 of the road additional strata are exposed, carrying the section up
