1898-1902. No. 32.] FOSSIL FAUNAS FROM SERIES B. 39 



Primitia arctica nov. sp. 

 PI. VIII, fig. 16. 



Some small pieces of black fine-grained limestone are rich in 

 minute ostracods, most of which cannot be nearer determined as they 

 are too incomplete. 



Also of the species named above I have only a single right valve, 

 The greatest length is 0.9 mm., greatest height 0,6 mm. The posterior 

 part is very globose, the sulcus not strongly defined, as the anterior 

 portion of the valve is only slightly elevated. Quite near the upper 

 margin and in front of the sulcus a strong nodule is situated. A broad 

 rim runs round the valve. 



Occurrence: B, upper part, near the fragment-limestone, Valley 

 south of Borgen.
