The earliest reported trematode from a deep-sea fish, Distomum halosauri Bell 1887 collected by the H.M.S. Challenger expedition, is redescribed from fresh material taken from the type host in the northwest Atlantic. The species is assigned to Degeneria gen. et comb. n. Distinguishing characteristics are the combinaion of a pharynx, cirrus pouch with internal seminal vesicle, disposition of the uterus into the forebody, large eggs, and location in the excretory system of the host. The relationship of Degeneria to other gorgoderids is discussed.
最早报道的来自深海鱼类的吸虫是1887年由英国皇家海军挑战者号探险队采集的哈洛龙双盘吸虫（Distomum halosauri Bell），现根据从西北大西洋模式宿主获取的新鲜标本对其进行重新描述。该物种被归入新属Degeneria及新组合。其鉴别特征包括咽、具内部精囊的阴茎囊、子宫在前体的分布、大的虫卵以及在宿主排泄系统中的位置。文中还讨论了Degeneria与其他戈尔戈德科吸虫的关系。
