| 在整理中国科学院海洋生物标本馆收藏的玉螺科标本时, 经形态分类和齿舌解剖学研究,发现了属于玉螺科的2 个新种, 即：马氏玉螺Natica maxiutongi sp. nov.和南海窦螺Sinum nanhaiensis sp. nov.。两新种均分布于南中国海, 其中马氏玉螺采自海南岛陵水和黎安的潮间带至潮下带浅海砂质海底, 壳面褐色或栗色, 体螺层上有3—4 条深褐色的螺带; 南海窦螺分别采自广东近海和南沙群岛海域水深105m 和102m 的泥质沙海底, 贝壳小, 呈长卵圆形, 壳面白色或淡黄褐色, 表面螺肋和生长纹细密。

| Abstract: |
| Two new species of Naticidae (Mollusca, Gastropoda), distributed in South China Sea, were recognized and classified morphologically in this paper, and the internal anatomy on radula was described based on the mollusk collection of the Marine Biological Museum, Chinese Academy of Sciences. Natica maxiutongi sp. nov. was found in sandy bottom from intertidal zone to shallow water near Lingshui and Li’an, Hainan Island, with maroon or brown shell, white base, and 3—4 dark-brown or light color banded body whorl. Sinum nanhaiensis sp. nov. was collected in mud-sandy bottom of shallow waters about 100 m depth offcoast in Guangdong and Nansha Islands, with small and elliptical shell in color of yellow-brown or white. The new species are described and comparison with similar species are conducted and discussed.
