Section IV. — Birdlip Hill. 



The road from Birdlip to Gloucester exposes a section of the 

 Lower Trigonia-bed. which rests upon thick-bedded oolitic lime- 

 stone, and is overlain by the lower portion of the Gryphite-grit. 

 The upper portion of that oyster-bank has been here denuded; but 

 the lower portion is Been m situ in a quarry about 150 yards from 

 the turnpike on the road to Cheltenham. It rests on the Trigonia- 

 bed, which consists of a coarse, light-coloured, fragmentary oolitic 

 limestone, containing many Conchifers, Braehiopods, and Ecliino- 

 derms, and separated from the freestone below by a hand of clay. 

 The lower Trigonia-bed here assumes the character which it presents 

 in so many other points of the southern and eastern Cotteswolds, 



where it has hem called •■ dypeus-grit," from its containing many 

 specimens of Olypeus Plotii. It must be remarked, however, that 

 this Glypeus-gril is not, as it has been figured and described by some 

 authors, a bed superior to On "/>/>< r Trigonia-grit of Leckhampton ; 

 hut is. in fact, the equivalent of the Lower Trigonia-bed in the pre- 

 ceding sections. Where it forms the appermosi stratum of the 

 [nferior Oolite, immediately underlying the Puller's-earth, either 

 the Upper Trigonia-gril and Gryphite-gril have been denuded, and 

 are absent, or, through the thinning oul or absence of the < hrj phite- 

 grit, the two Trigonia-beds have come into juxtaposition and formed 

 one Tri''onia-^rit .
