previously described from the Carboniferous Limestone of Bolland, 

 Yorkshire. 



Prom Beacon Quarry, Codden Hill, near Barnstaple, and from 

 "Westleigh. It also occurs in the Carboniferous Limestone of Vise, 

 Belgium. 



4. Goniatites [Pericyclus], sp. 



A small goniatite, although specifically indeterminable, belongs 

 to the section Pericyclus, a section which, so far as is known, is 

 confined to the Lower Carboniferous. It appears to be near 

 either G. [Pericyclus] virgatus, de Koninck, or G. [Pericyclus] 

 Hauchecornei, Holzapfel, both figured by the latter author from the 

 Lower Carboniferous of Erdbach-Breitscheid. 



From the Overton Quarry, Codden Hill, near Barnstaple (coll. 

 J. G. Hamling). 



Table II. (p. 655) has in part been drawn up from the List of 

 Fossils determined by Dr. Henry Woodward and Mr. B. Etheridge, 

 Jun., 1 from the Lower Culm shales of Waddon Barton, near Chudleigh, 

 to which have been added the fossils from the limestones and shales 

 of Canonsleigh and Westleigh, North-east Devon, obtained by the 

 late Bev. W. Downes, 2 which appear to have been determined 

 with some care. The cephalopoda in this list have been revised by 

 Mr. G. C. Crick, and we are indebted to Mr. A. Smith Woodward s 

 for the information respecting the two species of fishes from Instow. 



We have omitted references to fossil plants in the above-mentioned 

 list, for the reason that none are known to occur in the Badiolarian 

 Beds, and it is doubtful whether any have been determined from the 

 Lower Culm Measures as distinct from those in the Culm itself and 

 shales immediately associated therewith, which may be said to belong 

 to the Upper Culm Measures, with which we are not concerned in 

 the present paper. Mr. B. Kidston, F.G.S. (quoted by Dr. Henry 

 Woodward), 4 gives & list of 8 species of plants from the Culm, 

 which have a Calciferous Sandstone facies and are equivalent to 

 the Culm in Germany, but the precise horizon and locality whence 

 these plants came are not stated, and it appears that one of the 

 forms (and possibly others also) is from the Marwood Beds at 

 Sloly quarry, near Barnstaple, which are regarded 5 as of Upper 

 Devonian age. Prof. Phillips 6 has stated that plants occur in beds 

 corresponding to the Codden Hill Series at Lew Trenchard and 

 Truscott in the Launceston district, but it is doubtful whether these 

 plant-bearing beds are really the equivalents of the Badiolarian 

 rocks.
