The old statement that Artemia when bred through successive generations in water of diminishing salinity developed the characters of an allied genus " Branchipus," and that the latter developed into Artemia if the salinity were increased, was due to a confusion of taxonomic characters. The old " Branchipus," sensu lato, contained several diverse species. The true Branchipus, as nowadays defined, belongs to the family Branchipodidae. Thus in the experiments which gave rise to the above statement there w^as no change from one genus to another, but merely a variation of characters which are now regarded as not even specific.
