of the material brought back by Hartz in 1900. The most 

 striking feature is that the LamelUbranch-fauna of the <• brown 

 Jura» and also to some extent that of the «white Jura» show 

 a Middle-European character, whereas the Ammonites distinctly 

 have afflnities with those of Russia ^). Nor should the scarcity 

 of the Gastropods in the Jurassic beds of East-Greenland pass 

 unnoticed. It appears that, throughout the Arctic Jurassic, the 

 number of Gastropod species is remarkably small and this is 

 the case also in East-Greenland. 



The researches of Toula and Lundgren have already proved 

 that the East- Greenland Jurassic deposits are developed in a 

 similar manner to those of King Karl's Land and Franz Josef's 

 Land. The present work supplies further evidence in support 

 of this fact. 



Deposits occur in East-Greenland which must be referred to 

 the Bajocian or the Bathonian, to the Lower Callovian and to the 

 Lower Volgian (Middle-Portlandian) stages respectively. In King 

 Karl's Land^), beds occur, which have been referred to the 

 Bathonian, the Lower, Middle and Upper Callovian, to the Upper 

 Oxfordian, to the Kimeridgian and to the Lower and Upper 

 Volgian. In Franz Josef's Land^) are deposits, which have 

 been referred to the Bajocian, to the Lower, Middle and Upper 



M The plant-remains of the Rhætic-Liassic deposits of the west-side of 

 Hurry's Jnlet (see p. 164—5) have the closest affinity -with the Rhætic- 

 Liassic plant-remains of Scania and with the Rhætic ones of Franconia.
