<§r. Mr. Muller has alio described and figured it 
in his excellent work on the Animalcula Infusoria. 
It is numbered among the rarer animalcules, and is 
chiefly to be found in the months of February and 
March. 
In February 1798 I divided several of these ani¬ 
malcules in the manner above described; the re¬ 
spective fragments of each of which, in less than an 
hour’s space, assumed their complete form. One 
specimen, before dilaceration, had enclosed a Mo- 
noculus, which was no sooner liberated than it swam 
about, apparently uninjured by its captor.
