Cardium islandicum 

 Macoma calcaria 

 Mya truncata 

 Saxicava pholadis 

 Lepefa cceca 

 Balanus sp. 



On the east side of Moskusfjord, to the west of Havnefjord, the 

 following species were found in clay about 65 m. above sea level: 



Macoma calcaria 



Pecten islandicus 



Cardium islandicum 



Mya truncata var. uddevallensis 



Saxicava pholadis 



Balanus sp. 



Terraces of about the same maximum height as found by Schei in 

 Ellesmere Land are known to occur in other districts of the Arctic Archi- 

 pelago. In the report of A. P. Low on the cruise of the „Neptune",i 

 p. 235, is stated that along the eastern shores of Baffin Island, terraces 

 were constantly seen, which were estimated to rise from 500 to 700 feet 

 above the sea. The same height is given for terraces on the western 

 side of Hudson Bay, while at Cape Wolstenholme, on the south side of 

 Hudson Strait, the terraces rise to 800 feet. The highest terrace seen 

 (by Dr. Bell) on the north side of Hudson Strait had an elevation of 

 528 feet above the sea. Concerning the remarks in the paper cited as to 

 the theory of the greatest post-glacial land-uplift being found where the 

 accumulation of ice was greatest, the quaternary geology of Arctic 

 America does not, in the opinion of the present author, contradict it, since 

 the glaciation in Ellesmere Land seems, indeed, to have been at one time 

 much more intense than at present. 



As Schei in his „Summary of geological results" strongly emphasizes 

 the size of the glaciers has not been greater than at present, since the high 

 terraces were formed; that is, we have had no melting oft during this rise 

 of the land from about 180 m. to the present level — in other words in fairly 

 recent time. The high marine terraces are found so near present glaciers 

 that we must, on the contrary, assume that the latter must have advanced 

 in this youngest time. This is shown also by the fact that in the morainic 

 material formed at the margin of Leffert glacier at Rice Street, were 

 found molluscan shells [Mya truncata and Astarte arctica), evidently 

 moved from an original deposit farther inland, now covered by ice. 



As to the present glaciation of Ellesmere Land, what Schei in his 

 report, p. 8, writes on that subject, is cited below:
