| 摘要: |
| 利用光学显微镜对 8 种蛾螺科种类、3 种织纹螺科种类和 1 种细带螺科种类的齿舌形态进行了观察和比较。结果表明, 3 科 12 个种的齿舌均由 2 列侧齿和 1 列中央齿构成, 无缘齿, 齿式为0·1·1·1·0。蛾螺科种类(方斑东风螺、泥东风螺、台湾东风螺、深沟东风螺、缝合海因螺、香螺、甲虫螺和 Antillophos sp.)的侧齿具小齿 2—3 枚, 中央齿具小齿 3—7 枚。织纹螺科种类(半褶织纹螺、秀长织纹螺和红带织纹螺)的侧齿具小齿 2 枚, 中央齿具小齿 9—13 枚, 其基板的两端常延伸至下一齿排附近。半褶织纹螺具侧齿附板, 秀长织纹螺和红带织纹螺无侧齿附板。塔形纺锤螺的侧齿呈长形的梳子状, 具小齿 9—12 枚, 中央齿极小, 具小齿 3 枚。与其他学者的研究结果不同, 本研究未发现东风螺属种类的齿舌具有种特异性。侧齿附板不存在于所有织纹螺科的种类中, 其有无也不能作为同属或同亚属种类的共性。

| Abstract: |
| The radular teeth of 12 gastropods, including eight buccinids, three nassariids and one fasciolariid, were observed and compared using light microscope. The radulae of these species have 3 teeth per row, consisting of a central tooth (rachidian tooth) and two lateral teeth. The buccinid species (Babylonia areolata, Babylonia lutosa, Babylonia formosae, Babylonia spirata, Hindsia suturalis, Cantharus cecillei, Neptunea cumingi and Antillophos sp.) have two and/or three main cusps on the lateral teeth and 3—7 cusps on the central teeth. The nassariid species (Nassarius (Zeuxis) semiplicatus, Nassarius (Zeuxis) foveolatus and Nassarius (Zeuxis) succinctus) have 2 main cusps on the lateral teeth, but 9—13 cusps on the central teeth. N. (Z.) semiplicatus has accessory lateral plates, while N. (Z.) foveolatus and N. (Z.) succinctus do not. Fusinus forceps has small central teeth with three cusps and elongated multicuspid lateral teeth on either side. The results indicate that the radular teeth of Babylonia species are not species-specific, which disagrees with previous reports. The accessory lateral plates are not found in all nassariid species, and the existence or absence of the plates cannot be regarded as the common characteristics of nassariid species in the same genera or subgenera.
