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



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



Specimens without definite localities : — 



10. Spirifer cristatus, Schloth. 8. octopllcatus of the Mountain- 

 limestone is now regarded as the same species. 



11. Streptorhynchus crenistria, or an allied form. 



12. Zaphrentis Ovlbos, Salter (?). Probably an Arctic species. 



13. Stenopora ; a large branched species, like 8. Tasmaaiensis of 

 Lonsdale. This occurs at Bell Sound also. 



14. Syringopora, large fragments. 



15. A new genus, in all probability of the Fenestellidce, consisting 

 of thick stems branching regularly from opposite sides, the smaller 

 branches also opposite, and coalescing with their neighbours so as to 

 form a quadrangular network. But for this coalescence, it might be 

 a gigantic Thamniscus or IcMhyorhaehis. As the poriferous face is 

 not seen, it is better not to give a new generic name. 



From Black Point, in shaly beds, which seem to be associated with 

 the coal, slabs were obtained with numerous shells and some frag- 

 ments of plants. 



16. Nucula, abundant ; and amongst these is a small 



17. Aviculopecten, and a Spirifer with broad ribs. 



18. Aviculopecten. A large species (looking like the A. papyraceus 

 of our own coal-shales magnified), found in the gravel among the 

 Thousand Isles ; it probably came from these beds. 



A weathered block of white limestone, probably from the islands 

 on the south-eastern side of Spitzbergen*, contains the only truly 

 Permian species which I have seen among these specimens, viz., — 



19. Spirifer alatus, Schloth., a common fossil of the Zechstein. 



20. Productus, a small species. (P. horridus of De Koninck's list, 

 but apparently too deeply lobed.) 



21. Stenopora, a large foliaceous flattened species. 



Spirifer octoplicatus (cristatus), above mentioned, also occurs in 

 similar whitish limestone. These may possibly have all come from 

 the locality whence M. Robert's original specimens were found ; but 

 it would appear that they are not by any means the prevailing fossils 

 of the island. 



The general aspect of the fossils collected by Mr. Lamont is un- 

 questionably Carboniferous ; and some of the species have a wide 

 diffusion. Productus COStatus ranges from India to the Mississippi, 

 and P. semireticulatus (which T think is only a variety of the same 

 species) has even a wider rangef. P. Lfumboldtii is found in Russia 



* With regard to this specimen, the author, in reply to an inquiry on the sub- 

 ject, states — " The loose block of white limestone to which you refer as 'having a 

 Permian aspect ' was, it' I mistake nut. picked up mi one of the islands to the 8. K. 

 of Edge's Lai hI. || ^ unlike any rock I saw In situ; ami, a- it i- evidentlj a 

 travelled block, T think it not improbable thai it does nol belong i" Spiteberge i 

 at all, but may have been transported by the drift-ice from Comm aider I Kllies'a 

 Land or some other unknown country to the north-east."- ■April 21, I860.
