This is very similar to the species proper, except for its large i- 

 nuclei. Its cilia, better preserved than in the specimens of the species 

 proper, are seen to be of considerable length.

 dividing nuclei in the material may depend upon the time of year or 

 the method of preservation or the conditions under which the speci-
