618 E. ETHEE1DGE ON THE PALEONTOLOGY OF THE 



In addition to the foregoing, Dr. Toula describes amongst the 

 Actinozoa of his paper two species which I consider to be probably 

 Polyzoa ; they are : — 



17. J&hombopora (Ceriopom) bigemmis, Keyserling. 



18. Millepora (Pustulopora) oculata, Phillips. 



1876. Prof. A. E. Nordenskiold, in his < Sketch of the Geology of 

 Ice Sound and Bell Sound, Spitzbergen ' *, gives a note on the Car- 

 boniferous-Limestone fossils collected by Dr. Lindstrom during his 

 expedition of 1868, from which it appears that out of a total of 

 sixty-three species, seven were Polyzoa. Nordenskiold concludes 

 that the strata yielding the fossils are of Mountain-Limestone age, 

 but containing an admixture of species occurring in other countries 

 only in the Permian. 



1878. In concluding this bibliographical notice of hitherto de- 

 scribed Arctic Palaeozoic Polyzoa, so far as known to me, I have to 

 notice the species recorded by my friend Dr. J. J. Bigsby in his 

 recently issued ' Thesaurus Devonico-Carboniferus.' Within the 

 pages f of this remarkable epitome of the organic remains of the 

 Devonian and Carboniferous epochs is given a list of fossils from 

 Feilden Isthmus, lat. 82° 43' IN"., collected by Captain Feilden and 

 communicated by my father. They are : — 



Fenestella arctica, Salter. Polypora biarmica, Keyserling, 



cribrosa, Hall. grandis, Toula. 



intertexta, PortlocJc ? megastoma, Be Koninck. 



—— sp., near F. bicellulata, mihi. Ramipora Hochstetteri, Toula. 



Description of the Species. 



Genus Fenestella (Miller), Lonsdale, 1839. 



Fenestella, Murchison, Sil. System, p. 677; restricted by King, 

 Permian Foss. England, 1850, p. 35. 



Fenestella? aectica, Salter. 



Fenestella arctica, Salter, Belcher's Last of the Arctic Voyages, 

 vol. ii. 1855, p. 385, t. 36. f. 8. 



Sp. char. Polyzoarium flat, in one plane ; interstices thicker than 

 broad, zigzag, angular on the obverse face, rounded on the reverse 

 or non-celluliferous face ; dissepiments short, quite horizontal, of 

 equal breadth with the interstices, and similar in character ; fenes- 

 trules hexagonal, large, broad; here and there one maybe found 

 smaller and more irregular than the others, but, as a rule, they re- 

 tain their size and form with great regularity ; cells opening on 

 the angular faces of the zigzag dissepiments in two alternating 

 lines, one on each side ; reverse smooth to the naked eye, but finely 

 striated when magnified.
