PALXEO-GEOGRAPHICAL REMARKS. 



The Jura of Cape Flora will be of the greatest importance to the geo- 

 graphy of the Jurassic system. 



Here, in 80 N, Lat, we make acquaintance with the most northerly 

 Jura region of the earth 1 . 



One point of particular importance is the formation of marine Bajocian 

 at Cape Flora. Hence the existence of a Bajocian sea in the north of the 

 Eurasian Juracontinent is proved beyond all doubt. The occurrence of 

 true European species sueh as Lingula Beani Phill., Discina reflexa Sow. 

 sp. also of Belemnites sp. (cf. Beyrichi Opp.) at Cape Flora proves undeni- 

 ably the connection of this arctic Bajocian sea with the central and western 

 European sea of the Bajocian period, and especially a connection with the 

 Bajocian sea of Yorkshire, and England generally. A connection of this kind 

 is only possible in the west of the Eurasian continent, west of its Scandina- 

 vian part. Thus, as early as the Bajocian period, there existed a "Shet- 

 land Straits" (Neumayr), which separated the Eurasian continent existing 

 through the Lias period until the end of the Bathonian, from the nearctic 

 Juracontinent (Neumayr). 



The Shetland Straits of the Bajocian must have extended westwards from 

 the Lofoten island And0, for Lundgreen 2 recently proved with certainty that 

 the marine Jura fossils of Ando cannot be older than the Oxfordian. 



1 The Jura of Spitzbergen extends from about 77, 40' to 78, 20' N. Lat. During his 

 last polar expedition, at about 79 Prof. Nathorst discovered Jura on Kong Carl's Land. 

 The Jura of Kuhn Island lies in about 75 N. Lat., and the Jura of the arctic archi- 

 pelago of N. America in 76 77 9 N. Lat.
