WRIGHT UPPER LIAS SANDS. 



30.5 



fine soft ferruginous marly sandstone, of a deep brown colour, con- 

 taining much peroxide of iron, and many shells, mostly of the same 

 species as those found in the Cephalopoda-bed at Frocester. The 

 difference between these two beds is important, and deserves to be 

 noticed, as the Cephalopoda-be4 at Frocester overlies the sands, 

 whilst the fossiliferous vein at Nailsworth is found at their base, 

 clearly proving that the sands and Cephalopoda-bed form only one 

 stage.

* This list has been prepared from specimens collected by Mr. Lycett and 

 myself during many years, and I beg to thank my friend for the valuable aid he 

 has given me in making my list of Conchifera as complete as it now is ; the 

 specimens have all been determined with much care, and I believe every confi- 

 dence may be placed in the accuracy of our conclusions. The letters F. N. indi- 

 cate that the species has been found at Frocester or Nailsworth.
