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



under the basalt at Cape Flora, there is a soft gray-blue day of 500600 

 feet in thickness, in which numerous large and small nodules of reddish- 

 brown day sandstone are imbedded. Nansen noticed solitary thin strata 

 of basalt in the clay. The occurrence of thin strata of lignite is also men- 

 tioned as having been observed by Koettlitz in several places 1 . Judging 

 from the fossils, mostly included in the sandstone-nodules, but also lying 

 free in the clay, Prof. Nansen characterises the age of the day, underlying 

 the basalt of Cape Flora, as approximately identical with that of the Ox- 

 ford Clay*. 



In December 1897 Messrs. E. T. Newton and I. I. H. Teall 3 published 

 their investigations of the new material sent to England by the Jackson-Harms- 

 worth Expedition; and this paper is of great importance to our knowledge of 

 the geology of Franz Josef Land. By help of this collection, and statements 

 by Dr. Koettlitz, Newton ascertained that in the neighbourhood of Cape Flora 

 on Northbrook Island, Jurassic deposits "chiefly clay interstratified with shales 

 and bands of ironstone, lignite etc." of a considerable thickness (about 600 

 feet) underlie a cap of basalt extending over the whole district. Enormous 

 heaps of talus debris and gravel almost entirely cover the strata underlying 

 the basalt, and very seldom allow of an examination of the outcrop of these 

 strata in situ. 



Newton describes Jurassic fossils from different localities in the neigh- 

 bourhood of Cape Flora.

1 This statement may refer specially to the district round Cape Gertrude, east of Cape 



Flora. At Cape Flora lignite is found only in the lowest horizon 1 (b) south 



of Elmwood ; cf. the geological sketch by Prof. Nansen, p. 12 and 28.

 4 I quote here the names used by Newton. From the remarks in the descriptive part 



of this paper, it may be seen how far the determination of the fossils, published by 



Newton, is to be changed or accepted.
