460 NEW LAND. 



Among these are lamellibranchiata, Dechenella sp., remains of Holo- 

 ptychius, etc. 



This argillaceous sandstone is simultaneously the last link in 

 Series D, and the first in Series E. This is a huge collection of quartz- 

 sandstone strata building up the mountains on both sides of the inner 

 part of Gaasefjord. The lowest part, which is 900 to 1200 feet in 

 thickness, consists almost exclusively of quartz-sandstone. On the north 

 side of Skrabdalen, in the sandstone profile, occur conglomerate strata, 

 half an inch to an inch in thickness. In these were found considerable 

 remains of Coccosteus sp., Holoptychius sp., and Modiola angusta. In the 

 same strata with these were also seen indeterminable plant-fossils. 

 Slightly higher up in the profile, however, in a black shale which 

 occurred in two lentiform masses, eighteen inches and six feet in 

 thickness, were found numerous plant-fossils. 



Professor Nathorst, of Stockholm, who has kindly undertaken the 

 examination of these, says that among others are Arclmopteris ftssilis 

 Schmalh. and Arch, archetypus Schmalh., both characteristic of Upper 

 Devonian. In examining the material collected, Professor Xathorst 

 also found with the plant remains some remains of fishes. 



CARBONIFEROUS. 



Store Bjornekap at its lowest part consists of beds of brownish- 

 grey, hard, fossiliferous limestone ; higher up of a white pure lime- 

 stone, flinty limestone, and pure flint-strata, richly fossiliferous, among 

 the fossils being Lithostrotion sp., FenesteUa sp., Streptorhynchus crenistria, 

 Rhynchonella (P-ugnax) sp., Spirifer cfr. ovaUs,cwspidatus, mosquensis (?), 

 Product us cfr. semireticulatus, costatus, punctatus, com, etc. 



MESOZOIC FORMATIONS. 



The coasts on both sides of Heureka Sound consist chiefly of 

 quartz-sandstones with subordinate schists and limestones. Fossils are 

 only found in a few specimens collected from in all five places. Thus 

 from Ammonitberget on the northern point of Bjornekaplandet was 

 taken an ammonite and some lamellibranchs, among which perhaps is 

 DaoneUa LommelU. Likewise an ammonite and lamellibranchiata from 

 the marly sandstone on Hatden, in Bay Fjord, and from the black shale 

 of Blaafjeld, Daonella sp. 



TERTIARY. 



In the depressions between the mountains of Mesozoic sandstones 

 abutting on Heureka Sound, are in many places thick deposits of light
