332 DAVID BEYCE ON SOME ROTIFEKA FROM SPITSBERGEN. 



the mosses brouglit from Spitsbergen by Dr. J. W. Gregory in 

 1896. In the individual which. I compared with Scourfield's 

 (10) figure and description, the posterior processes were distinctly 

 more developed. Murray (7) has recorded this species from Loch 

 Morar in Scotland.
