The Systematics of the Crustacean Genus Callianassa.


  • Robert Gurney D.Sc., F.Z.S.


Beyond the somewhat obvious deduction that the present subdivision of the genus is ill-founded, it must be admitted that no clear conclusion can be drawn from the facts adduced. All that is claimed is that they justify an appeal to those to whom specimens are available of species not adequately described to re-examine them and provide the information upon which a revision of the genus may be founded.
