ABSTRACT

A new cyclodorippid crab, Berglundus bretoni n. gen., n. sp. (Cyclodorippidae Ortmann, 1892) from the Astoria Formation (early to middle Miocene) of Washington State is herein described. It represents the fourth genus of cyclodorippids in North America, keeping the stratigraphic range and the palaeogeographic distribution of the Cyclodorippidae unchanged.
