 Squamella limulina Bort de St. Vincent, Class. Anim. Micr., 1826, p. 90=Brach-

 That Miiller's Brachionus hractea was a Euchlanis is reasonably 

 certain from his figure and description, but it is impossible to identify 

 it definitely with any of the numerous species of this genus, and 

 Squamella Bory de St. Vincent must consequently be dropped.
