A further report on the Ostracoda of the United States National Museum

Abstract

In a previous paper bearing 2 similar title" a number of species of fresh-water Ostracoda belonging to the U. S. National Museum were briefly discussed, and two presumably new species described.Most of these forms were from scattered localities in the United States and Mexico, and represented the known ostracod fauna of these countries but meagerly.Since that paper was published, a number of marine as well as fresh-water forms have come to my hands for study.The marine forms were mostly collected by the U. S. Fisheries steamer A/batross.It therefore remains for me to give an account of these forms, and the present paper offers some results.Four species, apparently new to science, are here figured and described.
