Klaas Billen Bay : a long fjord at the head of Isfjord in 

 West Spitsbergen. Here also are mountains, and between them 

 and the sea a strip of raised beach forms comparatively low, 

 flat ground. The mosses were taken from a location in the 

 neighbourhood of the small collection of huts known as " Bruce 

 City," at the head of the bay. 



Mosses collected early August, 1921.

The mosses from Klaas Billen Bay furnished nearly all the 

 species of Rotifera which are included in the present report. 



From L 1 and 2 were obtained dead specimens of several 

 species of ordinary pool-dwelling rotifers which were recognised 

 from the more or less empty but distinctive loricae.
