摘要
采集中国沿海不同区域的方斑东风螺、泥东风螺标本,从这2种螺4个群体中每个群体抽样解剖30个个体,进行齿舌结构的对比.结果表明,东风螺属种间齿舌的区别主要体现在中央齿的中间突起,方斑东风螺种内不同群体间差别较小,但泥东风螺种内存在较大的中央齿第三突起基部角的差异.种间的差异要明显大于种内的差别,通过对结果的分析提出了一些通过齿舌鉴别东风螺属内各种的方法.
The radula of Babylonia areoluta and B. lutosa were morphologically compared in this article. The samples of each species had two populations from different coastal of China and each population has 30 individuals. The result comes that different species in the Babylonia genus has little disparity, and the discrepancy between species is obviously larger than that in the same specie. Some approaches to identify species in the Babylonea genus by radula have been broached.
