212 PROF. REYNOLDS AND MR. VAT7GHAN ON THE [May 1904, 



a limestone-band with vertebrate remains is recorded, but hardly 

 such a deposit as could strictly be termed a Bone-Bed. 

 . A consideration of the geographical position of the above 

 localities, shows that throughout Somerset, with the exception 

 of Emborough and Watchet, no true Bone-Bed has been recorded. 

 In the district to the immediate north of Bristol — Redland, Aust, 

 Patchway, Sodbury, but not Stoke Gifford — there is a single, well- 

 marked Bone-Bed at, or very slightly above, the base of the Black- 

 Shale Series ; while farther north, in the Gloucester district, the 

 principal Bone-Bed tends to lie at a greater distance from the base 

 of the Black Shales. 



The facts summarized above seem to render it clear that the 

 principal Bone-Beds of the various sections in the Bristol district 

 cannot be regarded as the homotaxial equivalents of one another ; 

 a conclusion to which, as already stated (p. 200), we have been 

 led by a comparison of the Sodbury section with that at Garden 

 Cliff. 



The following is a list of the principal localities in the Bristol 

 district where a section showing the base of the Rhaetic Series 

 occurs, with some references to the most recent, complete, or 

 accessible descriptions of the sections : —
