Having so recently discussed the fuller synonymy of this group, I may here limit 

 myself to repeating that the family in Hansen's acceptation includes the Anilocridae, 

 Saophridae, and Cymothoidae of the Monographia Cymothoarum by Schiiidte and 

 Meinert.

Other references are supplied in the last cited memoir. Canolira has what is 

 called page precedence over Anilocra, from which Leach distinguished it by the single 

 feature that the rami of the uropods are almost equal, of moderate length, with the 

 inner ramus slightly the longer, while in Anilocru the rami are unequal, elongate, the 

 outer the longer. This difference being untenable as a generic character, the two genera 

 coalesce, and Canolira as standing hrst would naturally have become the generic name, 

 but the only species which Leach assigns to it, Canolira rissoniana, of unknown habitat, 

 seemingly has not been identified, so that the name Anilocra, with wiiidi Leach con- 

 nected some well-tuscertained species, has properly been adopted.
