This section was taken in a ravine opening into the centre of 

 Kome Bay. The finest impressions of Plants, however, occur in 

 the neighbourhood of the house-sites, not far from the limit of the 

 gneiss, which here forms a high mountain, immediately east of 

 the river (Kook), which on that side seems to mark the limit of 

 the Lower Cretaceous beds of Greenland. 



Thick as the Lower Cretaceous strata are, they are now visible 

 only over a small area, as they merely fill the valleys between the 

 gneiss hills near the coast. The strata at Kome are separated by 

 gneiss hills from the strata at Pattorvik, and these again in the 

 same manner from those of Karsok, Angiarsuit, Avkrusak, and 

 Ekkorfat. The main mass of the formation, which evidently once 

 extended over Omenak Fjord, has been washed away. Whether or 

 not it extended inward, into Noursoak peninsula, under the basalt, 

 it is impossible to say with certainty, as several of the deeper 

 valleys are filled with ice. I think, however, that this is ex- 

 tremely probable, although the real Kome strata seem to be want- 

 ing at Atanekerdluk. They may possibly reappear between the 

 last-mentioned place, and the gneiss formation at Takkak. Calca- 

 reous strata are entirely absent in the Greenland Cretaceous, and 

 it is useless to look for marine fossils there : everything shows 

 that what we here have before us is a fresh- water deposit. 



The fossils are most numerous and best preserved in the lowest 

 strata, and consist principally of Ferns and Coniferas, Leaves of 

 Coniferae and other Plant-remains are also met with, although 

 rarely, in the upper strata ; but these, in consequence of their 

 friability, can hardly be preserved. As regards these fossils, 

 Prof. Oswald Heer has made the following communication : — 



"All the places where these remains have been discovered 

 (Kome, Avkrusak, Angiarsuit, Karsok, Ekkorfat, Pattorfik) have
