14. Syringopora, large fragments. 



15. A new genus, in all probability of the Fenestellidaz, con- 

 sisting of thick stems branching regularly from opposite sides, 

 the smaller branches also opposite, and coalescing also with 

 their neighbors so as to form a quadrangular net-work. But 

 for this coalescence it might be a gigantic Thamniscm or Ich- 

 thyorhachis. 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 associ- 

 ated with the coal, slabs were obtained with numerous shells 

 and some fragments of plants. 



16. ivMcwfa, abundant ; and among 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 southeastern 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 Zech- 

 stein. 



20. Productus, a small species. (P. Horridus of De Ko- 

 ninck's list, but apparently too deeply lobed.) 



21. Stenopora, a large foliaceous flattened species. 

 JSpirifer octoplicatus (cristatus), above mentioned, also oc- 



* With regard to this specimen, I stated, in reply to an inquiry on the 

 subject, "The loose block of white limestone to which you refer as 'having 

 a Permian aspect' was, if I mistake not, picked up on one of the islands to 

 the S.E. of Edge's Land. It is unlike any rock I saw in situ ; and, as it is 

 evidently a traveled block, I think it not improbable that it does not belong 

 to Spitzbergen at all, but may have been transported by the drift-ice from 

 Commander Gillies's Land, or some other unknown country to the north- 

 east."— April 21, I860.— J. L.
