Three new bathyal species of Paraliparis (Liparidae) are described from Tinian and Anatahan Islands, and from Esmeralda Bank, in the Mariana Islands. All were collected in shrimp traps set at 903–1207 m. Although liparids have been found, described, and studied at hadal depths in the Mariana Trench, Paraliparis echongpachot sp. nov., Paraliparis kadadakaleguak sp. nov., and Paraliparis marianae sp. nov. are the first species of the family described from bathyal depths of the Mariana Islands. The existence of three species from collections at three locations in the same archipelago, and their distinctiveness from liparids known from other areas in the western Pacific to the north and south of the Mariana Archipelago, is in accordance with the high degree of endemism in species of Paraliparis. Biogeographic and liparid life-history factors that influence bathyal fish distributions in the Mariana Archipelago and enhance endemism in Paraliparis are discussed.

三个新的半深海物种Paraliparis（Liparidae）从天宁岛和Anatahan群岛，并从埃斯梅拉达银行描述的那样，在马里亚纳群岛。全部收集在设在903-1207 m的虾圈中。尽管已经在马里亚纳海沟的海底深度发现，描述和研究了类脂动物，但Paraliparis echongpachot sp。十一月，Paraliparis kadadakaleguak sp。十一月和Paraliparis marianaesp。十一月 是从马里亚纳群岛的海床深处描述的该家族的第一个物种。同一群岛中三个地点的集合中存在三种物种，它们与西太平洋其他地区到马里亚纳群岛南北北部的脂类动物的区别在于，该物种的高度特有性副唇肌。在生物地理和liparid生活史因素影响半深海鱼分布在马里亚纳群岛和增强特有Paraliparis进行了讨论。
