Two new species of Eirene i.e. E. macrogonia Huang, Sun et Liu , sp. nov. and E. zhanjiangensis Huang, Zhang et Zao sp. nov. are decribed. All type specimens are deposited in College of Ocean and Earth Sciences, Xiamen University. The specific diagnoses of two new species are as follow: Eirene macrogonia Huang, Sun et Liu sp. nov. Unbrella nearly hemispherical; gastric peduncle long, exceeding beyond the velar opening, the base pyramidal shaped; with 4 radial canals and a ring canal; with 4 large sinuous gonads, from near the base of the peduncle to beyond the umbrella margin along the four radial canals with 19−24 marginal tentacles of the same size, its bulbs without excretory papillae, with 5−8 rudumentary bulbs. Eirene zhanjiangensis Huang, Zhang et Zao, sp. nov.Umbrella hemispherical, jelly think; the base of gastric peduncle pyramidal and the end narrow; lenth of manubrium near equal to the one of oral lips; 4 gonads banding shaped, extending from the base of peduncle to near umbrella margin along the 4 radial canals; with 4 radial canals and a ring canal; with 70−125 marginal tentacles of the same size, its bulbs with excretory papillae; the number of statocysts about 1/2 of one of tentacles.
