A few collections taken from West and East Okoboji Lakes and Spirit lake in June, and from the sloughs of the Des Moines River in the fall of 1886, have added six more species to the list of Cladocera in the state, as given in the ''Proceedings" of the Academy for 1895. Five of the species are common to the country, and one is a hitherto undescribed species of Daphnia. A few individuals of a form of the difficult genus Bosmina were found which may be the young of Bosmina longirostris, O. F. Muller. If not the young of this species then seven instead of six species will be added to the list.
