boulders {N:os 111, 120, 128 and 129) containing fossil remains, the 

 rocks in these cases presenting a nearer agreement with those from 

 the Mallemukfjæld and the Eskimo Naze, especially as regards the 

 finer-grained specimens, even if there also exists some connection 

 with the coarser-grained too. 



At a height of 60 metres above the sea there was found in gray, 

 fairly fine-grained limestone (N:o 129), a large trunk of a Syringo- 

 pora, and unimportant remains of other corals. 



At 165 metres above the sea were found the other three {N:os 

 111, 120 and 128), all containing brachiopods, and Dr. Wegener 

 considers them to derive their origin from the limestone at the 

 summit of the mountain. N:o 111 is the rock in closest agreement 

 with those from Mallemukfjæld — Eskimo Naze, and can hardly be 

 distinguished from them. It is a grayish-yellow, fairly finely cry- 

 stalline limestone, containing some few grains of a dark mineral, 

 and some fossil remains, especially silicified brachiopod shells. 

 There is also a fairly well preserved ventral valve of a Spirifer (n. 

 sp., ex. aff. Sp. duplicicostae Phill.). 



Each of the other two fragments {N:os 120 and 128) contains a 

 silicified specimen of the ventral valve of a large Prodiictus; N:o 

 120 of Pr. boliviensis d'ORB., and N:o 128 of Pr. inflatus M'Chesn. 

 Both rocks are somewhat more coarsely crystalline than N:o 111, 

 and do not seem to contain any dark constituent parts. 



As the strata here in Ingolfs fjord, like those at Hekla Sound, 

 dip to the east, we have here, in the Cape Jungersen section and 

 the River sections, too, parts of a continuous profile, where the 

 purer limestones at the top are superimposed on the alternating 

 sandstone and limestone strata in the lower parts of the profile. 



C. Sophus Müller's Naze and Henrik Kröyer's Islets. 



In addition to the collections that were made on the south coast 

 of Amdrup's Land in Ingolfs fjord, there are also some smaller ones 

 from the eastern part of Amdrup's Land, on the south side of Ant- 

 arctic Bay, viz., a) Wegener's collections from Henrik Kröyer's Islets 

 and the mainland behind them (27. 4. 1907), which places, in We- 

 gener's diaries, and on the labels, are given as "Observationsø ved 

 nordligste Teltplads" (Observation island; the most northern camp- 

 ing-place) and "nordligste Teltplads paa Fastlandet" (the northern- 

 most camping place on the mainland), and b) the collections that 

 Avere made (26.4) at Sophus Müller's Naze (on the labels marked 

 "Eskimoboplads 80°55'), and probably carried home to the vessel by
