Description of Two New Species of the Genus Eulimnadia and Notes on the Other Phyllopoda of Illinois

Abstract

The Phyllopod crustacea of Illinois, particularly of the Order Conchostraca, have been given but little attention. The Order Anostraca has been studied and reviewed by Forbes (1876) and Van Cleave (1928). Van Cleave listed three species of Anostracans for tho state, Eubranchipus serratus, E. vernalls, and Striptocephalus seali (S. Coloradensis). The occurrence of Pristicephalus (Eubranchipus) bundyi has not been definitely established, so will be omitted in the list and key for the species found in Illinois. Since a complete list, and discussion, has been given for this group the writer will include these forms only as a part of a key for the Phyllopoda of the State of Illinois;-the bulk of the paper will be devoted to a discussion of the Order Conchostraca. The Order Notostraca has not bIen recorded in Illinois.
