localities sufficient fossil evidence to determine the particular 

 position which these beds on the N.E. of the Quantocks occupy in 

 the order of geological sequence. I will now proceed to describe 

 in detail the different sections, and the position of the fossil- 

 bearing beds in these sections. The first examined was that which 

 I call Holford or Woodlands quarry. The harder beds which are 

 at the base have been here worked back for the purpose of 

 obtaining " metal" for the roads, and consist of a series of fissile 

 sandstones, much coloured externally with peroxide of iron (as all 

 the rocks in the neighbourhood are), imparting a bright red tinge 

 to every thing it comes in contact with, I say externally, for upon 

 fracture the beds present a more or less grey colour. The bottom 

 beds which have been worked down somewhat below the level of 

 the road are close-grained purplish grey sandstones, with greenish 

 coloured marly partings ; in these traces of plants occur. Succeeding 

 them in ascending order is a series of thicker beds of a dense 

 silicious texture and lighter grey colour, also very fissile. A con- 

 venient little section has been made in these beds close to the road 

 side of about 5ft. in depth, and it was near the middle of these 

 beds that I came upon the fossils. A thin, rotten, dark-coloured 

 parting here separates the close-grained sandstone beds, and in this 

 occurs abundance of Encrinital plates, casts of Brachiopods, Corals, 

 and Tentaculites. The dense grey sandstone itself also yields fossils 

 though not in the same abundance, and they seem to die out 

 altogether the further you search upwards from the rotten parting, 

 as if the conditions of the sea bottom became gradually less and 

 less favourable to animal life. At the back of this quarry, which 

 has been worked down some 20 or 30ft., about half way up a dark 

 rotten arenaceous band almost black (but drying red) comes in ; 

 as this reminded me very much of similar bands in N. Devon, in 

 which I had found abundance of organic remains, I was not long 

 in ascertaining its contents, and found a similar series of fossils to 

 those below. Owing, however, to the extremely friable nature of 

 the matrix it was very difficult to carry away any perfect specimens. 

 All these beds have a more or less S. E. dip, but the harder beds 

 near the base run more rapidly away beneath the road at an 

 angle of 25° to 30° S.E.
