SUMMARY Interglacial Cladocera (Crustacea) from Iceland by Ámi Einarsson Institute of Biology, University of Iceland, Grensásvegur 12, 108 Reykjavík, Iceland An investigation of peat in the Elliðavogur interglacial strata revealed a number of Cladocera fragments. The species composi- tion (Table I) indicates low arctic or sub- arctic conditions. This conforms well with pollen analyses and an analysis of Coleop- tera remains ntade by previous investigators from the same deposits (Thorkelsson 1935, Pflug 1959). The age of the strata is still uncertain, but they are of late Pleistocene age (less than 700.000 years old) and older than the Holsteinian interglacial (Einarsson 1968; Hjartarson 1980).
