sufficiently perfect to indicate genuine or specific characters, we are only able to- 

 enumerate the following : — 



Species of Onchus Murchisoni, Agass. SiL Syst. pi. 4, f. 10. 



Teeth of Thelodus parvidens, Agass. SiL Syst. pL 4, f . 34—36. 



Teeth resembling tkose figured in SiL Syst. pi. 4, f. 37, but serrated at the 

 margin. 



Ganoid scales. 



The only molluscous remains in the fish-bed are the Orbicula rugata, Sil. 

 Syst. pL 5, fig. 11, and an Orthis. 



In some places fragments of coaly matter similar to that in bed No. 8, 

 are mixed up with those osseous remains. One of these carbonaceous pellets 

 seems to be the seed of some terrestial plant. It is globular, about a quarter of 

 an inch in diameter, and being broken across exhibits a central cavity, the 

 parieties of which are about one-tenth of an inch thick, and composed of fibres 

 radiating to the external surface. 



The bed No. 10 corresponds in character with the uppermost strata of the 

 Ludlow Bocks, wherever they are visible in the neighbourhood. It is a fine 

 grained sandy shale of a greenish or greyish colour, abounding with small par- 

 ticles of Mica, and effervesces with acids, although not sufficiently calcareous to 

 deserve the name of a limestone. 



The following organic remains occur in it at the Hagley Park quarry : — 



Favosites ■polymorpha, Goldf., SiL Syst. pi. 15, f. 2. 



Cophinus dubius, Konig., SiL Syst. pL 20, f. 12. 



Cyathophyllum, E. 



Crinoidal stems, pentagonaL 



Cyathocrinites macrostylum, Phillips's Manual Geol. Survey, ii , p. 384. 



Scrpulites longissimus, Murch, Sil. Syst. pi. 5, f. 1. 



Homalonotus Kuightii, Konig., Sil. Syst. pi. 7, f. 1—2. 



Calymene Blumenbachii, Bronga, Sil. Syst. pi. 7, f. 5. 



Rhynchonella semisulcata, Dalm (under the name of Terebratula lacunota, 

 Sil. Syst. pL 5, f. 19). 



R. Wilsoni, and R. nucula, Sow. Sil. Syst. pi. 6, f . 7 ; and pi. 5, f. 20. 



Orthis orbicularis, and O. lunata, Sow. Sil. Syst. pi. 5, f. 15 — 16. 



Stroplwmena filosa, Sow. Sil. Syst. pi. 13, f. 12. 



Leptcena sarciculata, Schlott (L. lata) SiL Syst. pi. 5, f. 13. 



Orbicula striata, and 0. rugata, Sow. Sil. Syst. pi. 5, f. 11—12. 



Lingula minima, Sow. SiL Syst. pi. 5, f. 23. 



Orthonota amygdalina, and O. retusa, Sow. SiL Syst. pi. 5, f. 2 and 5. 



Avicula ampliata, Phillips, Man. Geol. Survey, ii., pi. 3, f. 1. 



Orthoceras bullatum, and O. ibex, Sow. Sft Syst. pi. 5, f. 29 — 30. 



O. perelegans, Salter, Man. Geol. Survey, ii., pL 13, f. 2 ; and 



O. gregarium, Sow. SiL Syst. pi. 8, f. 16. 



Many of these fossils, especially the Orthocerata, are penetrated with 

 sulphuret of iron, which gives them a bright metallic gloss.
