rtfrt* tSdte liegmde of Germany. And the fragments of porphyry 

 included in it, are supposed to be the remains of pre-existing trap- 

 Tocks ; both from their rounded form, and their admixture with the 

 detritus of other formations inferior to the new red-sandstone. 



This red conglomerate occupies three small districts : — 1. That of 

 St. Mary Church and Watcombe. 2. Tor-Moham. 3. Paington. — 

 The first extending along the coast from the Ness Point (Teignmouth) 

 to Oddicombe Sands ; with the exception of an insulated mass of car- 

 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 cur\'es and contortions in the limestone strata 

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

 from the old red sandstone. And jyi 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 imparted to it 

 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, anri 

 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 (he Alcyonia ; but whether 

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

 tween thecrinoidea and echinodermata, has not yet been determin«.'d. 



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

 celebrated from its containing the remains of various antediluvian 

 animals, is in this carboniferous limestone.

 siderable space in this country, is well txj)0sed at Cockington, v here
