SYNCH.STA TREMULA (Muller). 



Vorticella tremula MiJLLER, Anim. Infus., 1786, p. 289, pi. 41, figs. 4-7.

 cella tremula renamed . 



Fitrcularia tremula Blainville, Diet. Sci. Nat., vol. 60, 1830, p. 152. 



Synchseta tremula Ehrenberg, Abh. Akad. Wiss. Berlin (for 1831), 1832, p. 135. 



Synchxta truncata v. Hofsten, Arch. Zool., Stockholm, vol. 6, No. 1, 1909, p. 36= 

 Synchseta tremula renamed. 



V. Hofsten considers Vorticella tremula Muller different from 

 Synchseta tremula of Ehrenberg, and renames the latter. This 

 seems unnecessary. In the case of these old names we must accept 

 the assertions of successive authors, that they have recognized the 

 older species, unless we are in a position to prove their identification 

 erroneous. If we did not, we would have to make a fresh start 

 about every 25 years, and it is not evident that we would be any 

 better off.
