R0CX8 OF SOUTH DEVON. 511 



Dr. Kayser identified the Clymenice as C. Icevigata and C. annu- 

 lata. 



The Goniatite-limestone of Lower Dunscombe, with overlying red 

 slates or shales, forms a very small patch, faulted against Culm- 

 measures on the east and west and overlying the massive limestones 

 on the north and south, in the form of similar compact, con- 

 cretionary, red limestones ; it also occurs in a triangular patch 

 bounded by faults at the westernmost termination of Ugbrooke Park, 

 near the pathroad to Lewell. The Chndleigh limestoiie is probably 

 folded or thrust over the greenish slates, which bound it on the 

 west, the latter being of Upper-Devonian aspect. In the middle 

 or lower part of the limestone Mr. Clement lieid * found Heliolites 

 joorosus ; the same coral in association with MhyncJionella cuhoides 

 was found by me in the Woolborough limestone in Lang's Copse ; 

 hence it becomes a question as to the relative importance of the 

 Coral or the Brachiopod in determining the Middle- or Upper- 

 Devonian age of the rocks. There is, however, no reason to object 

 to the Middle-Devonian age of the lower part of the Chudleigh 

 limestone. 



Dr. Kayser's list of fossils from the Groniatite-limestones in Lower- 

 Dunscombe Quarry consists of: — 



Goniatites intumescens. 



acutus. 



simplex. 



Cardiola retrostriata. 

 Myahna. 



Herr Erech identified in these beds, in addition to the above : — 



Groniatites complanatus (a variety of intumescens). 

 Cyrtoceras and Harpes. 



Add to these Goniatites midtilohatus (G. Sagittarius) found by 

 Mr. Lee f. 



In the disturbed districts between Ipplepen and Newton- Abbot, 

 Upper-Devonian beds have not been detected by their fossils, except 

 in the case of the Ramsleigh % limestone, and the presence of 

 volcanic materials appears to have irregularly interfered with the 

 accumulation of the limestones ; but it is probable that the red 

 slates between Woolborough and Abbotskerswell, and those 

 bounding the Lang's-Copse limestone, may be Upper Devonian, as 

 also the slates and tuffs south of East Ogwell. Even in this ex- 

 cessively faulted and complicated district, however, a patch of 

 Upper Devonian is proved to occur on the south of the faulted 

 termination of a mass of Culm-measures near Rydonball Cross, be- 

 tween Eydon Earm and Abbotskerswell Cross. Here a band of 

 grey and red, compact, nodular, concretionary limestone, with 

 irregular yellowish-brown kernels of decomposed limestone, occurs 

 in red, greenish, and grey slates resembling those of Livaton, Lewell 

 pathroad, and the Teign Bank opposite Combe-Cellars. These
