212 THE ZOOLOGIST. 



very convex oral end could be made out while the Eotifer was 

 performing these rapid movements. Its distinctive pair of 

 anterior tufted projections and its large pendent and richly 

 ciliated auricles were, however, very clearly seen after it had 

 been narcotized. Two specimens were obtained by dredging 

 from the end of the plank and beneath the ice which covered 

 the pool on January 27th, 1914. Both were very rapid in their 

 movements, and one of them went through evolutions precisely 

 like those described above ; the other, however, went round and 

 round for some seconds in a flat spiral, and then swam in the 

 same manner as the other, repeatedly doubling on itself. These 

 and other specimens obtained during the winter did not seem 

 to be as brilliantly white and transparent as the specimens 

 obtained in the spring. 



Quite recently, on April 11th, 1914, I obtained several speci- 

 mens of S. pcctinata by dredging in the clear water of Bedmond 

 Pool, which is situated in a deep excavation at the northern end 

 of the village. These specimens and those from Chipperfield 

 Common Pool are the only ones so far obtained.
