280 APPENDIX. 



found there which occurred at Bear Island. And, inasmuch as 

 the Producti are the common British species P. giga?tieus and 

 P. Cora, there can be no doubt whatever of the formation to 

 which Spirifer Keilhavii belongs. Count Keyserling de- 

 scribed a variety of it from Petschora Land under another 

 name ; and in the Appendix to Belcher's " Last of the Arctic 

 Voyages" I have figured and described this shell from the Car- 

 boniferous rocks of North Albert Land — Captain Belcher's 

 farthest point. Numerous Producti occurred with it, two of 

 which, if not more, are identical with the Spitzbergen species. 

 I notice this more particularly, because in two communications 

 to the Royal Academy of Brussels (Bulletin, vols. xiii. and 

 xiv.) Prof, de Koninck has described the Bell Sound fossils as 

 Permian, and not Carboniferous species, and has given figures 

 of several of them. In a short resume of the Arctic Geology 

 read by myself to the British Association, 1855, 1 have used 

 this fact as illustrative of the regularity of the great Arctic 

 basin of Palaeozoic rocks (Trans. Sect., p. 211). 



One species only which appears to me of Permian date oc- 

 curs in a loose block (without definite locality), and will be 

 presently noticed. It would be somewhat remarkable if all 

 the specimens brought home by M. Robert should prove to be 

 Permian, while those from the same locality before us are mostly 

 of Carboniferous type. The larger and more conspicuous shells 

 do not seem to have been met with by M. Robert in his voyage. 



8. Fenestella, two species, one with very large meshes. 



9. Sponges (?) ; large, stem-like and cake-like in shape. 



Specimens without definite localities : 



1 0. Spirifer cristatus, Schloth. S. octoplieatus of the mount- 

 ain limestone is now regarded as the same species. 



11. Streptorhynchus crenistria, or an allied form. 



12. Zaphrentis Ovibos, Salter (?). Probably an Arctic spe- 

 cies. 



13. Stenopora ; a large branched species, like JS. Tasman- 

 iensis of Lonsdale. This occurs at Bell Sound also.
