Lundgren considers that the Cape Stewart beds should be 

 identified with the Middle Jurassic («Dogger») deposits of Kuhn 

 Island. «The four European species found at Cape Stewart 

 all occur in the Callovian deposits of Europe and the general 

 character of the fauna is in close agreement with that of the 

 Callovian. Plicatula cf. spinosa, alone, seems to point rather 

 to the Lias, but too much importance should not be attached 

 to this fact. The Jurassic deposits of Cape Stewart should 

 then, in my [Lundgrens] opinion, be referred to the Callovian 

 and they certainly have a Middle-European character, as far as 

 the Lamellibranchs and Brachiopods are concerned. As regards 

 the Cephalopods, these are not well enough preserved for any 

 conclusions as to the age of the beds to be definitely based 

 upon them». 



The observations upon the Jurassic deposits of Jameson's 

 Land were further supplemented in 1899, by the Swedish expe- 

 dition under the leadership of A. G. Nathorst ^). 



On this expedition Nathorst discovered a sandstone crop- 

 ping out on the western shore of Hurry's Inlet, near Point 

 Constable. This sandstone is mottled red and white and rather 

 coarse-grained; but higher up, at a height of 71 metres, it is 

 white, shaly and contains kaolin; higher still, it is of a brown- 

 ish colour. At a height of 120 metres a basalt-sheet protrudes. 

 Above this, blocks of a greenish sandstone were found, which 

 is probably in place there, the same blocks occurring up to 

 a height of 231 metres. Still higher up, a rock was seen, 

 similar to the plant-bearing Rhaetic beds of Cape Stewart; and
