Crenella faba, O. F. Miuer. 
(Fig. 1.) 
Locality: 
July 29. 1898. Egedesminde. 
Aug. 5. y Upernivik, 8—26 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 Cressin crenella faba attains a size of 12 mm., though 
PossELt on the other hand gives its size as 18mm. Three of the Fram 
Expedition’s specimens measured: 
Upernivik Long. 8.5 mm. — Lat. 7) mm. Crass. 4.5 mm. 
Egedesminde 10.2. 85 , 5.0, 
Stordalen 13. x 10.2 , 6 yy 
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 Cressin 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, 0O—470 m., and at Cumberland Sound, Baffin Land (Prerrer, 
Daut). It is also said to have been found at Iceland, though accord- 
ing to Possett this is doubtful.
