Kuhn Island off the east coast of Greenland (see the map). The 

 material collected by Julius Payer and Ralph Copeland was exam- 

 ined by Franz Toula in Vienna. Toula's researches demonstrate 

 clearly that the development of the Jurassic beds in Kuhn 

 Island is of a two-fold nature. On the east coast are light-grey, 

 calcareous marls and fine-grained micaceous quartz-sandstones 

 of a yellow or grey colour; the petrological nature of these 

 rocks recalls somewhat that of the « Quadersandstein •>, but their 

 fossils, on the other hand, show the strongest affinities with 

 those of the Jurassic rocks of Russia. On the south side are fine- 

 grained, calcareous sandstones of a dark greyish-brown colour, 

 containing flakes of mica; also coarse-grained sandstones filled 

 with shells, and regular shell-breccias, in both of which coal- 

 seams occur. All these rocks belong probably to the middle 

 «Dogger», The Jurassic deposits of Kuhn Island rest directly 

 upon crystalline rocks, which stand out between the two types of 

 deposits, forming a lofty mountain ridge covered with glaciers. 



The following fossils are quoted as occurring on the 

 east coast: — 



Perisphinctes Payeri, nov. sp.
