Madsen, if his determination of a Simbirskites is correct, 

 to belong to the youngest Jurassic or possibly the Lower 

 Cretaceous. 



Nothing is known as to the continuation of the formation 

 further north. Nathorst's observations at Antarctic Harbour 

 are characterized by himself as uncertain, no distinct fossils 

 having been noticed, but the pétrographie descriptions tally 

 with a continuation of both the monotonous Jurassic beds and 

 the motley Triassic series. However, the statement quoted 

 above shows that one must by no means exclude the assumption 

 that still more recent beds, of the cretaceous formation, may be 

 met with in this district on some future occasion. 



As to the petrographical character of the Jurassic bed 

 there is not much to add. At the shores of Hurry Inlet nu- 

 merous blocks of a Scolithus sandstone, already observed by 

 Bay, were seen. It may be mentioned that red formations are 

 not altogether lacking. So, in the interior of Jameson Land, 

 I found, for instance, a glaring brick-red sandstone alternating 

 with the normal or light-coloured. But the colour is very un- 

 like that found in the older formations and points rather to a 

 secondary colouring in later times. 



Finally I may mention that conglomerates do not seem 

 to be unusual, but that, in sharp contrast to the older for- 

 mations, the pebbles most usually — exceptions may occur — 

 are composed of quartz. This, too, most probably is connected 

 in some way with the obviously divergent conditions under which 

 these strata were formed, a knotty problem into which I cannot 

 enter here. 



The new plant fossils from Hurry Inlet district will be de- 

 scribed later by Hartz. 



6. The Cape Leslie sandstone. During the expedition of 1891, 

 in the most easterly part of Milne Land, i. e. opposite Jameson 

 Land, Bay came across a fairly large series of sandstone resting
