Crenella faba, 0. F. MULLER. 



(Fig. 1.) 

 Locality: 



July 29. 1898. Egedesminde. 



Aug. 5. Upernivik, 826 m. 



Aug. 18. Camp Clay, Cape Sabine, 4 10 m. 



July 30. 1900. The entrance to Stordalen, Havnefjord. 



At Upernivik this characteristic West Greenland species was quite 

 common, whereas from each of the other localities only one or two 

 specimens were obtained. 



According to CLESSIN crenella faba attains a size of 12 mm., though 

 POSSELT on the other hand gives its size as 18 mm. Three of the Fram 

 Expedition's specimens measured: 



Upernivik Long. 8.5 mm. Lat. 7 mm. Crass. 4.5 mm. 



Egedesminde 10.2 8.5 5.5 



Stordalen 13 10.2 6 



In quite young specimens the radiating ribs are seen also on the 

 inner side of the shell, whereas in older individuels they only appear as 

 a narrow band at the edge. Otherwise the inner side is smooth. 

 According to CLESSIN the inner side of the shell is light-brown, but in 

 the specimens which I examined it was of a lustrous bluish-white, and 

 only at the edge of the shell was there a brown rim. 



Crenella faba has not previously been met with in the waters 

 north and west of Baffin Bay. Formerly it was only known to occur 

 on the west coast of Greenland, where it is distributed from Ivigtut to 

 Melville Bay, 0470 m., and at Cumberland Sound, Baffin Land (PFEFFER, 

 DALL). It is also said to have been found at Iceland, though accord- 

 ing to POSSELT this is doubtful.
