ZELINKIELLA SYNAPT.S: (Zelinka). 



Discopus synaptse Zelinka, Zool. Anz., vol. 10, 1887, p. 465. 



Janson (Uebers. Rot.-Fam. Philodinaen, 1893, p. 50) drops the 

 name Rotifer parasiticus, which he credits to Lankester (Quart. Journ. 

 Micr. Sci., n. ser., vol. 8, 1868), as a synonym for Discopus synaptse 

 Zelinka. I have not been able to locate this name; it was not used 

 by Lankester in the article referred to, and nowhere else, as far as I 

 have been able to ascertain.
