At Coomb Hill, near Cheltenham, the Bone-Bed is difficult to 

 find, but I have succeeded in discovering a typical development. 

 From the writings of H. E. Strickland also, it is known that the 

 lithic and faunal characters of the stratum here are similar to those 

 which may be noted at that end of Wainlode Cliff which is farthest 

 from the Red Lion Hotel ; for. to quote that author, it 



'rarely exceeds an inch in thickness, and frequently thins out in short 

 distances to one-fourth of an inch or less. It consists chiefly of a dense mass 

 of scales, teeth, bones and small coprolites, cemented by pyrites, the golden 

 colour of which contrasts beaut if idly with the jet-black of the animal-remains.' x 



The fragments, Strickland noticed, ' have evidently been subjected 

 to a gentle mechanical action.' as they often present ' broken and 

 worn surfaces." 



In the shallow cutting through which the Tewkesburv-and- 

 Ledbury road passes at Sarn Hill, near Bushley, the Bone-Bed- 

 equivalent is a massive stratum of yellowish micaceous sandstone, 

 14 inches thick, and is separated by 2 feet 8 inches of Black 

 Shale from the ' Tea-Green Marls,' with a sharply-defined line 

 of junction. 



At Bourne Bank, near Defford ("Worcestershire), the Bone-Bed- 

 equivalent resembles that at Bushley, but is here 2 feet thick, 

 and is devoid of vertebrate-remains. In a ' Postscript to the 

 Memoir on the Occurrence of the " Bristol Bone-Bed " in the Neigh- 

 bourhood of Tewkesbury,* Strickland brought forward evidence to 

 show that an ossiferous development of this Bone-Bed-equivalent 

 was passed through by a shaft sunk on Defford Common, about 

 half-a-mile to the east of the escarpment. 2 Pieces of this bed 

 brought to the surface yielded to Strickland his ' Puttastra 

 arenicola.'' and teeth, scales, and coprolites of fishes. The actual 

 junction of the Keuper and Bhgetic Series cannot be seen at Bourne 

 Bank : but, in a road-cutting about 2~ miles to the north, the 

 deposit intervening between the Bone-Bed-equivalent and the 

 Keuper Marls is seen to be 2 feet 10 inches thick. The Bone-Bed- 

 equivalent here is similar to that at Bourne Bank, and is exposed 

 for a thickness of 13 inches, but that is not its total thickness ; the 

 section then becomes obscured, and the details are doubtful. 



The most important section now open in "Worcestershire is at 

 Crowle. Here, instead of the sequence, ' Tea-Greeu Marls," Black 

 Shale, Bone-Bed-equivalent, we have, in ascending order, ' Tea- 

 Green Marls,' Sandstone (with a little shaly matter intercalated 

 near the base), shales, and Bone-Bed-equivalent. The deposit of 

 sandstone above the ' Tea-Green Marls ' is therefore an addi- 

 tional deposit, and has come in between this locality and the 

 section near Croome D'Abitot. Indeed, it has come in between the 

 farm called Muckenhill and Croome D'Abitot, for in the farm- 

 yard it is seen resting upon the ' Tea-Green Marls,' and similar 

 phenomena are to be observed at Churchill Wood, near Spetchiey.
