 It is singular that throughout the able paper from which these extracts

Mr. Lubbock's paper, on the Freshwater Entomostraca of South 

 America, contains characters of ten described and four new species: 

 the previously known species were described by Baird, Dana and 

 Gay ; the new ones are Cypris australis, C. brasiliensis, Diaptomus
