That this does not fit the animal, which Ehrenberg calls Rotifer 

 macrurus Schrank, should be evident to any one who has seen the 

 latter. Schrank added nothing to Hermann's description, which 

 may probably be considered sufficiently vague to be dropped.

 ser., vol. 5, 1893, pp. 205-209. As Western's description of Callidina 

 sordida appeared in the same number, No. 32, it is evident that his 

 name has priority over Janson's.
