boniferous limestone at Petit Tor, which is bounded by the conglo- 

 merate, and partially overlaid by it. 



The conglomerate of Tor-Moham, connected with that of St. Mary 

 Church by an isthmus, is of similar composition, and rests upon car- 

 boniferous limestone and old red-sandstone. 



Near Paington, the conglomerate abuts against the old red-sand- 

 stone ; and having fallen from the cliff in considerable quantity, near 

 Livermeed and Preston Sands, has the appearance of underlying the 

 latter. 



2. Carboniferous Limestone. — The rocks of this formation in the 

 neighbourhood of Torquay, have hitherto been regarded as belonging 

 to the transition series ; but the author supposes them to be identified 

 with the carboniferous or mountain limestone, by their mineralogical 

 characters and organic remains. The limestone is of a gray colour, 

 traversed by numerous veins of carbonate of lime, is occasionally in- 

 terstratified with marl, and generally reposes upon argillaceous shale, 

 — the lower limestone shale of the carboniferous series. In the vici- 

 nity of trap, however, it assumes a semi -crystalline structure, and 

 thus affords the numerous varieties of the well-known Babbacombe 

 marble. 



Very remarkable curves and contortions in the limestone strata 

 are visible near Torquay ; the disturbed beds in general dipping away 

 from the old red-sandstone. And on the west of Babbacombe, the 

 coast exhibits the limestone and shale in great confusion ; particularly 

 where it is in contact with the trap of the promontory called Black 

 Head. 



At Saltern-Cove, near Goodrington, the limestone is intermixed 

 with, and disturbed by, trap, — which appears to have assumed the 

 character of serpentine, and to have so altered the calcareous rock 

 that it does not effervesce with acids. 



The author gives a general list of the organic remains in this de- 

 posit : including trilobites, encrinites, corals, nautili, orthocerse, and 

 several species of testaceous mollusca characteristic of the carboni- 

 ferous limestone. A very singular fossil also is figured, which appears 

 to have been attached in the manner of the Alcyonia ; but whether 

 it is to be classed with the corals, or considered as intermediate be- 

 tween thecrinoidea and echinodermata, has not yet been determined. 



The cavern called Kent's Hole, near Torquay on the N.E., lately- 

 celebrated from its containing Ihe remains of various antediluvian 

 animals, is in this carboniferous limestone. 



3. Old Red-sandstone. — This formation, which occupies a con- 

 siderable space in this country, is well exposed at Cockington, where 

 the sandstone is compact, micaceous and siliceous, and associated 

 with a slaty rock. Near Ockham, and N.N.W. of Paington, the 

 lowest beds lose their red colour, becoming more schistose ; and 

 these, as well as the grit and slate of Meedfoot Sands, seem to pass 

 into grauwacke. The old red-sandstone is extensively overlaid by 

 unconformable beds of the new red conglomerate at Chelston near 

 Cockington, and in other places.
