 the Macquarie; pink clay from the cataract below Wellington 

 Valley; porphyry from Mount Harris; hard, granular, quartz rock

A paper was next read, entitled " An Account of Land and 

 Freshwater Shells found associated with the Bones of Land Quad- 

 rupeds beneath diluvial Gravel, at Cropthorn in Worcestershire," 

 by Hugh Edwin Strickland, Esq., F.G.S. 



On two former occasions Mr. Striekland laid before the Society 

 brief notices of the discovery, near Cropthorn, of the bones of extinct 

 quadrupeds associated with shells of existing species, and the pre- 

 sent paper contains the result of his continued researches. The 

 deposit in which they were found is situated on the main road from 

 Evesham to Pershore, and on the east side of the small rivulet which 

 flows from Bredon Hill towards the Avon. In May 1834 the deposit 

 presented a section about 70 yards in length and 8 feet 6 inches high 

 in the middle. The lower part of it consisted of lias clay, on which 

 rested a layer of fine sand, containing 23 species of land and fresh- 

 water shells, with detached fragments, more or less rolled, of bones 

 of the Hippopotamus, Bos, Cervus, Ursus, and Canis. The sand pas- 

 ses upwards gradually into the gravel, which extends to the surface, 

 and differs in no respect from the other diluvial beds in the neigh- 

 bourhood. The gravel is composed principally of pebbles of brown 

 quartz, but occasionally contains chalk flints, and fragments of lias 

 Ammonites and Gryphites. The bones, though most abundant in the 

 sand, are interspersed through the gravel ; but the shells are entirely 

 confined to the sand. Lists are given of the bones and of the species 

 of the shells, two of which are considered to be extinct. The au- 

 thor from these phaenomena assigns the deposit to the newer plio- 

 cene era ; and from the fluviatile habits of some of the shells, he con- 

 siders that it occupies the site of an ancient river bed, and not of a 

 lake. In the course of his paper he points out the inferences which 

 may be drawn from the deposits respecting the greater change 

 which has taken place in the mammifers of this island than in the 

 molluscs, since the era when the gravel was accumulated ; and the 

 little change which the climate appears to have undergone since the 

 same epoch. In conclusion he notices the published accounts of 

 similar deposits at North Cliff, near Market Weighton, and at Cop- 

 ford, near Colchester, and his having been informed when at Bath, 

 that freshwater shells had been discovered under gravel in sinking 

 for foundations in the lower part of the city. 



A notice was afterwards read, " On the Bones of certain Animals 

 which have been recently discovered in the calcareo-magnesian Con- 

 glomerate on Durdham Down, near Bristol," by the Rev. David 

 Williams, F.G.S. 



The author commences by observing, that the calcareo-magne- 

 sian conglomerate of the neighbourhood of Bristol has hitherto been
