preserved. Four groups of reptiles are represented, viz. : Crocodiles, 

 Theropod, Sauropod and Arnidured dinosaurs. 



The Crocodilian remains, all attributable to Steneosaurus, are the most 

 plentiful. Next in point of numbers are those of the Theropod dinosaur 

 Megalosaiirus, which is represented by vertebrae, part of a mandible, a 

 sacrum, two coracoids, an ilium, an ischium, a femur and parts of the 

 scapula and humerus. The Sauropod remains, no doubt to be attributed 

 to Cetiosaurus, are less plentiful but include a caudal vertebra, two ribs, a 

 coracoid and two ischia. 



In some respects the most interesting find was two dermal plates of 

 Stegosaurus. 



Prof. 8. H. Reynolds. — A section of Rheetic and associated strata at 

 Chipping Sodbury, Glos. 



The section is seen in the big Carboniferous Limestone quarry north of 

 the village. 



The interest of the section lies in : 



(i) The fine development of the Rhaetic, particularly of the bone bed, 



which is in part of a coarsely conglomeratic character and resembles 



that of dust. 



(2) The nature of the Palaeozoic surface, which in the western part of 

 the quarry shows the uneven character due to sub-aerial erosion, 

 while in the eastern part it is planed down to a level platform, the 

 later stages at any rate of the levelling being doubtless the work of 

 the Rhaetic sea. 



(3) The fact that parts of the Carboniferous Limestone platform stand 

 at different levels, this being clearly the result of thrust faulting of 

 post-Rhastic date which followed the bedding planes.
