Begins: "The small collection of fish leeches (Rhynchobdellae: Piscicolidae) reported in this study was taken by the Galathea Expedition 1950-1952. The collection is of special interest for two reasons: the depths from which the specimens came and the large size of one of the species. Three of the lots were made at depths of 3570 to 4400 m, two others at 290 and 610 m. The greatest reported depths of which we zre aware for marine and freshwater leeches are, respectively 582 m (MOORE & MEYER 1, 951 : 23) and 1000 m (DOGIEL & BOGOLEPOVA, 1957: 447). The length of Galatheabdella bruuni n. sp. described below, qualifies it along with Carcinobdella kanibir Oka, 1910 (which Soos [1965: 4411 has synonymized with Notostomobdella cyclostoma [Johansson, 1898]), N. laeve (Levinsen, 1882), and some species of Pontobdella as the largest of Piscicolidae leeches. Only two of the leeches in the collection were accompanied by host data. Evidently the other specimens left their hosts during ascent to the surface in the trawl or after the mass of animals and debris was emptied on the ship's deck and awaiting examination, as usually happens. We are grateful for the kindness of Dr. TORBEN WOLFF for referring the material to us. The material is kept in the Zoological Museum, Copenhagen."
