map PI. XXX according to their value: # ^ sections; -|- = finds 

 of rocks and fossils in situ, and Q = finds of loose fossils or loose 

 stones. 



Sections have been made in 4 places, the most southern in two 

 spots on the outer part of Hekla Sound, and the most northern in 

 two places in the outer part of Ingolfs Fjord. The two southern- 

 most sections lie direct W. of Mallemukfjæld, at a distance from 

 each other of a couple of hundred metres ; the most western, on 

 the labels and in the diaries, has been called Koch's section, and 

 the most eastern, the Conglomerate section. They lie in the 

 immediate vicinity of Depot 80^09', and from them have been 

 obtained the greater part of the plant-fossils described by Nathorst 

 and the profile figure communicated by Jarner to Nathorst, and 

 which is reproduced here too, is referable just to these sections^ 

 perhaps Koch's chiefly (see below). 



On the north coast of Ingolfs Fjord, two profiles have been taken, 

 one, the most westerly, in the "Western river", and one at the 

 mouth of the fjord, about 3 miles W. of Cape Jungersen called the 

 Cape Jungersen section. In addition, the specimens collected 

 at the Eastern river are so related that conclusions can be drawn 

 from them respecting the sequence of the strata, and that, with a 

 tolerable amount of accuracy, they can be formed into a profile 

 connected with that from the eastern river. 



Fossils from the solid rock have also been collected ; at Malle- 

 mukfjæld, on the north coast of Ingolfs Fjord, on the Henrik Kröyer's 

 Islets and on the mainland behind these latter (depot 80°43'). 



Free-lying fossils and rock specimens have been collected: in 

 Hekla Sound, W, of Koch's profile; at Mallemukfjæld; at Eskimo 

 Naze; on the north shore of Ingolfs Fjord; on the Henrik Kröyer's 

 Islets; on the mainland behind these, and at Sophus Müller's 

 Naze, i.e., in addition to the find-localities for solid rock, collections 

 of free-lying material have been made at Eskimo Naze and at 

 Sophus Müller's Naze. 



As the sections that have been taken — incomplete although, it 

 is true, they are — contain fossils that can be referred to certain 

 geological levels, and also certain characteristic rocks, a comparison 

 between them can give a fairly collective view of the stratigraphy 

 of the district. In the following pages, therefore, a detailed description 

 of the various occurrences of the fossils will be given. 



It has not always been possible to make the petrological des- 

 cription of the various kinds of rock sufficiently positive, in conse- 

 quence of the often rather small supply of material available, so 

 that the comparison between the different rocks from the various.
