Knudsen-Gorsline 1953–1955

Section Responsible for Processing



Worms from Baja California.


Jens Knudsen, a graduate student studying crabs under Dr. John Garth at the Allan Hancock Foundation, University of Southern California, made several trips to Baja California. On at least one trip he was accompanied by Donn Gorsline, a grad student in the Department of Geology, USC. Specimens they collected were brought back for the Allan Hancock Foundation collections. The Polychaete Section has field records of 70 sites where Knudsen collected worms in September 1953 and January-February 1955. Dr. Olga Hartman first identified them to family, genus, or species level. Later, Dr. Kristian Fauchald re-identified them to species. The publications resulting from his thesis concentrated on families with jaws (Onuphidae, Eunicidae, Lumbrineridae, Iphitimidae, Arabellidae, Lysaretidae, Dorvilleidae) and deep water species. Most of the Knudsen-Gorsline specimens have not been cited.
