508 MR. W. A. E. USSHER ON THE DEVONIAN 



Buckley- Wood quarry, on the opposite side of the valley, yielded 

 Strornatopora FJiqjscJw, Barg., and Actinostroma clathratmn (?), 

 Nich., kindly identified by Professor Nicholson. 



The Ramsleigh limestone contains small Erachiopods at a short 

 distance north of the quarries, amongst them the llev. G. F. 

 Whidborne identified Spirifer Uneatus, Martin, and Waldhemia 

 Whidhornei^ Da v. 



A similar Brachiopod-horizon occurs in a patch of limestone at 

 Daggers-Mellons Copse between the Broadridge-AVood and Bradley- 

 Manor limestone masses. Amongst these small Brachiopods may 

 be, as Dr. Kayser kindly informs me, Nucleospira lens, Schnur, 

 perhaps Spirifer Urei, Fleming. Mr. Whidborne identified Merista 

 plebeia. 



The fibro-crystalline calcite veins termed " Strom atactis " by 

 Dupont abound in the limestones of Petitor and Ramsleigh (or 

 Eansley), and have also been detected by Prof. H. A. Nicholson in 

 specimens from Bickley Wood, near Whiteway Farm, and from Upper 

 Bradley, near Newton-Abbot. 



2. The Goniatite-heds. 



Some months ago I visited Elbury Cove to test the boundary of 

 the Brixham limestones and the slates which there apparently 

 underlie them. 



These slates exhibit Upper-Devonian characteristics. After a 

 fruitless search for fossils in them, I proceeded along the coast to 

 Silver Cove, where more or less massive limestones are apparently 

 underlain by tolerably thin, plicated limestone, passing down into 

 red slates and mudstones, through red slates intercalated with thin 

 bands and plaques of limestones. The whole was so suggestive of 

 the Saltern-Cove Goniatite-mudstones that I searched diligently, 

 and was rewarded by the discovery of the Saltern-Cove fauna. 

 The Goniatites are much crushed ; but well-preserved examples of 

 Cardiola retrostnata and numerous Bactrites were obtained. 

 Further investigation proved the junction to be inverted, the thin 

 beds of limestone occurring in their natural position in the low 

 cliff's of Galmpton Point. 



The Galmpton-Point limestones are full of Alveolites, and they 

 resemble the llamsleigh limestone in colour and texture. The 

 Silver- Cove and Elbury slates extend as far west as the borders of the 

 Talberton volcanic series ; and they also occur in Fishcombe Cove, 

 near Brixham. 



The Upper-Devonian slates of Saltern and Silver Coves are 

 chocolate-red, weathering to a lilac-red hue, which is distinct from 

 the colour of the red Lower-Devonian slates, against which they are 

 faulted at Saltern Cove. 



The Silver-Cove and Galmpton-Point limestones seem to be repre- 

 sented by the limestone bands and coralline masses which occur 

 in Saltern-Cove railwa5'-cutting, on the beach, and at the point on 

 the south of the large Cove, in which places, as Mr. Champernowne
