I. — Devonian Fossils from the Parish of St. Minver, North 



Cornwall. 



By Howard Fox, F.G.S. 



I CONTRIBUTED a paper to the April number of the Geo- 

 logical Magazine for 1900 on the geology and fossils of the 

 Devonian rocks on the north coast of Cornwall, south of the River 

 Camel. In the present communication I propose to notice a series 

 of fossils which I have lately obtained from the slaty rocks of 

 Devonian age in the parish of St. Minver on the north of the Camel, 

 which, from Trewornan, one mile north of Wadebridge, for the 

 lower five miles of its course as river and estuary, forms the 

 southern and south-western boundary of this parish. The open 

 sea-coast forms its northern and north-western boundary, extending 

 from the easterly limit at the Cove of Port Quin, the site of an old 

 but now forsaken fishing village, about eight miles south-west of 

 King Arthur's Castle, Tintagel, westwards round the basaltic clifis 

 of Pentire Head, and thence in a southerly direction to the estuary 

 of the Camel. 



The fossils generally occur partially weathered out on the surface 

 of the slates of the low clifis and beaches along the coastline and 

 estuary. We propose first to refer to the principal localities where 

 they have been obtained, beginning at Port Quin and following the 

 northern and western coastline to the estuary, and then eastward, 

 along the southern boundary to Trewornan. The names of the 

 places mentioned will be found on the 6 inch maps of the Ordnance 

 Survey. 



The first locality west of Port Quin where fossils have been found 

 is at the small cove of Epphaven, about a mile distant. In bluish 

 slates at this place a fragmentary Ophiurid (Brittle-star) was 

 obtained by Miss Barbara Legg in 1902. The specimen has been 

 described and figured by Dr. Bather under the name of Sympterura 

 Minveri, n. g. et sp., in the accompanying paper. The same slates 

 also contain detached crinoidal stem-joints and minute spine-like 

 bodies referred to Styliola.
