抽象的。根据1998年2月和2000年2月在特拉诺瓦湾采集的两个标本，最近描述的深龙类，Acanthodracodewitti Skora，1995年的成年人首次在罗斯海被记录。提供了分生组织计数和形态测量，并与Skora报告的结果进行了比较。标本为处于性腺成熟发育阶段的雌雄个体。与格鲁吉亚南部特有的近缘种短头裸龙（Psilodraco breviceps）相似，提出了短头裸龙的环南极分布。Dewitti讨论。
Abstract. On the basis of two specimens collected in Terra Nova Bay in February 1998 and 2000, adults of the recently described bathydraconid, Acanthodraco dewitti Skora, 1995 are documented for the first time in the Ross Sea. Meristic counts and morphometric measurements are provided and compared with those reported by Skora. The specimens were male and female in a developing stage of gonad maturity. Differently from the related species Psilodraco breviceps, which is endemic to South Georgia, a probable circumantarctic distribution of A. dewitti is discussed.
