The Mollusea of East-fireenland. 



I , 



Lamellibranchiata. 



The first information regarding the mollusc-fauna of East- 

 Greenland was procured by «Die zweite Deutsche Nordpolar- 

 fahrt». In the account of the results of this the so-called 

 Germania-Expedition Prof. K. Möbius has worked out the 

 molluscs ^). Of Lamellibranchiata 9 species are mentioned which 

 were all collected at Jackson-, Clavering-, Sabine- and Shannon 

 Isles: Modiolaria laevigata Gray («Ж discors L.»), Cardium 

 groenlandicum Chemn., Ästarte borealis Chemn., Astarte elliptiea 

 Brown («A. sulcata d. C»), Astarte Banksii Leach («^. com- 

 pressa Mont.»), Astarte crenata Gray («^1. crebricostata Forb.»), 

 Venus fluctuosa Gould (<^ V. astartoides Beck»), Mya truncata L. 

 and Saxicava arctica L. («Ä. rugosa L.»). 



Then a quantity of molluscs was collected by the zoologist 

 E. Bay during the Danish East-Greenland expedition, 1891—92. 

 The working of these molluscs was left to H. J. Posselt 

 who in the «Riks Museum» in Stockholm also investigated the 

 material collected by Nordenskiold's expedition in 1883 at 

 the south-eastern Greenland. Thus Posselt's list^) over the 

 Lamellibranchiata came to include 23 species, viz.: Fecten groen-
