1900. Northern part of Hurry-Inlet, Liverpool-Coast. Numerous valves, of a 



more or less elongated shape, a few var. uddevaïlensis. 



1900. Northern part of Hurry-Inlet, from different banks, Ryders-Elv at the 



main river. Several valves, of a rather elongated var. uddevaïlensis. 



1900. Northern part of Hurry-Inlet, quite down at the tributary, 20 — 30 feet 



above the sea-level. 6 valves, of var. uddevaïlensis and of a little 



more elongated shape. 



1900. Polhem-Dal in Forsblad-Fjord. Numerous valves, of var. uddevaïlensis 



and of a little more elongated shape, partly very thick valves. 



The Nathorst-Expedition of 1899 also found it fossil in 

 several localities, namely: at the mouth of Sophia-Sound (partly 

 in the variety ovata); at the south-side of Franz Joseph-Fjord; 

 at Scott Keltie-Island, and on the continent south of this locahty; 

 in Dusén-Fjord in the inner part of Forsblad-Fjord M. 



Saxicavidae. 



Cyrtodaria Kurriana Dunker. 



1901—02. Tasiusak '/a- 5 fms. 4 specimens. 



1900. Jameson-Land .... On shore 1 valve. 



1900. Sabine-Island Laminarians 4 specimens (3 empty). 



The specimens are small. The largest specimen from 

 Sabine-Island measures only 39 mm., the largest from Tasiusak 

 125 mm. 



To the distinguishing features between this species and 

 Cyrtodaria siliqua Spengler set forth by Dunker ^j I shall add 

 that the shell in С Kurriana is proportionately elongated. 

 While the height of a 51 mm. long specimen of C. siliqua 

 makes 40 ^/o of the length, is the proportion in a 39 mm. long 

 specimen of С Kurriana only 36 °/o, though the elongation is 

 evenly increasing with the augmenting size.
