34: U. Green Sf C. D. Sherhorn — Silurian Fossils, Cormoall. 



In the Geological Magazine, July, 1904, p. 289, one of us had the 

 pleasure of recording the occurrence of Ludlow fossils at this spot 

 in the same beds, and that discoveiy renders the present one of 

 additional interest. The fossils, which have been handed over to 

 the Geological Survey, are as follows : — 



Ptilodiclija lanceolata, Lonsd. 



FenesteUa assimilis, Lonsd. 



FenesteUa cf. B.M., D 571, from Wenlockian of Dudley. 



FenesteUa sp. 



MiUepora cf. rejiens (L.). 



Monticnliporid, ramifying through the whole mass of the 

 lenticle. 



BhijncJioireta cuncata (Dalm.). 



AmpJiiccelin striata (Sow.). 



Ptcrincea sp. 

 In the Autumn of 1905 we again visited Porthalla, and after 

 working three days found another fossil in the " Slates with 

 inclusions " on the beach of Nare Cove. This was a pyritized 

 Orthoceras comparable with 0. hullatnm, Sow., and 0. vinjatus, Sow., 

 both of Ludlow age, and distinct from the forms found similarly 

 mineralized in the Devonian beds, by reason of the casts of its 

 siphuncular chambers being barrel-shaped instead of parallel-sided. 

 It is preserved in the British Museum and registered as B.M., 

 C 10529. 



Three days work at Polyne Quarry, in the Taunusian beds, 

 yielded thousands of fossils. The bulk of these are in so bad a state 

 that it is difficult to recognize even the genus, but careful collecting 

 and a knowledge of the better specimens to be obtained in Germany 

 render it a comparatively easy task to select sufficient identifiable 

 examples. The following list shows the fossils obtained, the more 

 interesting of which have been placed in the British Museum 

 (Nat. Hist.) :— 



FenesteUa. 



Fachypora. 



Petraia pauciradiata (Phillips). B.M., R 7502, 7503.

Petraia radiata, IMueuster. B.M., R 7496, 7561. 



Petraia puiu'tatocrennhita, Roemer. B.M., R 6978. 



Petraia gigas, McCoy. B.M., R 2833, 613. 



Plenrodicti/um prohlematicum, Goldfuss. B.M., R 6072, 6973. 



ZodaneUa mira, Kayser. B.M., P 7697. 



Neritopsis. A fine series, some showing a broad expanded 

 mouth. B.M., A 1158-1160. 



Phacops ferdinandi, Kayser. Six quite typical eyes, one of 

 which showed part of the head-shield. B.M., 1 7233, 7234. 



Strophodonta gigas, McCoy. 



Streptorhynchus. 



Athyris cf. nndata, Defr.
