42 POMPECKJ. JURASSIC FAUNA OF CAPE FLORA. [NORW. POL. EXP. 



Atnm. (Macrocephalites} Ishmce, Keys. var. arcticus of Newton, from 

 the locality of Windy Gully (300 feet, or according to Kcettlitz, more than 

 400 feet above the sea) is perhaps also found in situ. 



Judging from the occurrence of Am m. (Gadoceras) Tchefkini?, d'Orb. 

 and Amm. (Macrocephalites) macrocephalus, Schloth. Newton concluded that 

 the "Lower Oxfordian and probably the equivalent of the British Kella- 

 ways Rocks" is represented in the Jurassic strata underlying the basalt at 

 Gape Flora. He is of opinion that Amm. (Macrocephalites) Ishmce Keys, 

 var. arcticus of Newton may possibly correspond with the Cornbrash. 



As to the age of the fragments of Avicula and Belemnites found west 

 of Elmwood, Newton could draw no certain conclusions. 



Nor does he express any very certain opinion with regard to the age of 

 the plant-remains found on the north side of Cape Flora, and which Prof. 

 Nathorst declared to be probably Upper Jurassic (White Jura). 



The age of other strata containing plant-remains in the Franz Josef 

 Land Archipelago, Newton 1 also leaves undecided. West of Cape Flora, at 

 Cape Stephen, and between this place and Cape Grant (in the South of Alex- 

 andra Land), hard calcareous sandstone with carbonized plants, bituminous 

 paper-shales and lignite occur. The flora of this horizon, perhaps the lowest 

 of the Franz Josef Land Archipelago, according to Newton, most resembles 

 that of the lower Tunguska district described by Schmalhausen "as of 

 Oolitic age". According to later researches 2 the plants of the lower Tunguska 

 are perhaps however of Permian age. Thus the plant-bearing strata of Cape 

 Stephen are possibly also of Permian and not of Jurassic age, provided that 

 they correspond with those of the lower Tunguska. 



1898. Dr. Reginald Kcettlitz gave in 'a brief sketch of the Geology' 3 a 

 report of the results of the geological researches which he had made as a 

 member of the Jackson-Harmsworth Expedition. According to his observations, 

 sandstones and shales containing plant remains, "beds of lignite, and other 

 evidences of littoral and estuarine conditions" are among the lowest of the
