or fringe, and were thought by Archer to be pseudo- 

 podia or prolongations of the ectoplasm ; chiefly for 

 this reason he placed D. mobile in a separate genus. 

 The cils, however, are of a rigid nature very similar 

 to those of Nebela barbata and Lecythium bathybioticmn ; 

 there is therefore no more reason for separating this 

 species from the genus Pseud odiffhtgia than for remov- 

 ing the above species from their respective genera.
