and of having been subjected to slight mechanical action. The ex- 

 istence of gentle currents is further proved, he says, by the presence 

 of small rounded pebbles of white quartz, a substance of very rare 

 occurrence in the liassic series. The only shell found in the bed at 

 Coomb Hill is a smooth bivalve, but too imperfect to be generically 

 determined. 



2. Wainlode Cliff, three miles west -south-west from Coomb Hill. — 

 The section exposed at this locality has been laid open by the action 

 of the Severn, and consists of the following beds : — 



Ft. in. 



1 . Black laminated clay, inclosing, near the top, a 



band of lias limestone with Ostrese 22 



2. Slaty calcareous sandstone, with a peculiar 



small species of Pecten 4 



3. Black laminated clay 9 



4. Bone-bed, passing into white sandstone 3 



5. Black laminated clay 2 



6. Light green angular marl 23 



7. Red marls, with zones of a greenish colour . . 42 



Dip very slight to the south. 98 7 



The bone-bed is far less rich in organic remains, accumulations of 

 fragments of bones and coprolites occurring at rare intervals ; and 

 its prevailing character is that of a fissile, white, micaceous sand- 

 stone, sometimes acquiring a flinty hardness. The upper surface of 

 the bed is ripple-marked, and in some cases presents impressions 

 considered by Mr. Strickland to have been probably made by the 

 claws of Crustacea. A small bivalve is also the only shell found in 

 the bed. The stratum No. 2, the author says, is evidently a con- 

 tinuation of No. 6. of the Coomb Hill section. 



3. Bushley, two miles and a half west of Tewkesbury. — The inter- 

 section of the lias escarpment by the Ledbury road near Bushley 

 afforded Mr. Strickland the following section : — Ft. in. 



1 . Black laminated clay, about 10 



2. Lias limestone 4 



3. Black laminated clay ! 6 



4. Compact slaty bed with numerous small bi- 



valves, and the Pecten of Wainlode and 

 Coomb Hill 3 



5. Black laminated clay 9 



6. White micaceous sandstone, with impressions 



of two species of bivalve shells 1 



7. Black laminated clay 2 6 



8. Greenish marl, about 20 



9. Red marl '. — - 



Dip about 8° east. 49 1 



The sandstone bed, No. 6, agreeing precisely with that at Wain- 

 lode Cliff, Mr. Strickland does not hesitate to consider it the repre- 

 sentative of the bone-bed, though organic remains are wanting ; and 

 he points out the identity of the stratum No. 4. with the beds Nos.
