List of fossils from the Lower Culm-shale of Waddon-Barton, near Chudleigh, 

 Devonshire, revised and augmented by Mr. R. Etheridge, junr., and Dr. H. 

 Woodward, from Mr. Lee's collection, and from other sources. 



Genera, Species, and Remarks. 



1. Orthoceras striolatum, Sandb. (chiefly as external casts). 



2. — sp. (there are probably more than two species of Orthoceras). 



3. Goniatites mixolobus, Phill. (as figured by Roemer). 



4. — sphcericus, Martin, sp. (as figured by Roemer). 



5. Posidonomya Becheri, Bronn. 



6. — corrugata, Eth. (? or young of P. Becheri). 



7. Pecten, sp. nov. ? (of a Carboniferous facies, but differing from any figured by 



von Koenen). 



8. Pteronites, sp. (form related to P. persulcatus, M'Coy). 



9. — sp. (form related to P. latus, M'Coy). 



10. Avicula lepida, Goldf. 



11. Ghonetes rectispina, von Koenen. 



12. — defiexa, von Koenen. 



13. Spirifera Urii, Fleming. 



14. Fenestella, sp. (in the condition known as Hemitrypa Ribemica, M'Coy). 



15. Phillipsia Leei, H. Woodw. (PI. X, figs. 1, 2, 3, 4). 



16. — minor, H. Woodw. (PI. X, figs. 5, 6 a, b, 7, and 8 a). 



17. _ Clifford^ H. Woodw. (PI. X, figs. 8 b, 9, 10, 11, 12). 



18. — articulosa, H. Woodw. (PI. X, figs. 6 c, d, and 13). 



19. ? Bernix Tatei, Jones (this form also occurs in the " Tuedian "). 



20. Casts of small corals (probably Monticuliporidce). 



21. Casts of small bodies (probably Sponge-Spicula). 



It is highly probable, when more of the shale shall have been carefully 

 examined, that many other small organisms will be added to our list, but the 

 intractable nature of the matrix has precluded our doing more at present. 



It may be interesting to record the fact here that in the " Tuedian " group or
