草席钟螺属

草席钟螺属（学名：Monodonta），是原始腹足目钟螺科的一属。
拉马克于1801年将本属从林奈的钟螺属（Trochus）中分离出来，以草席钟螺（Monodonta labio）为模式种。
本属的学名直译就是「单齿螺」，而这名称也是来自中国大陆的文献最普遍使用的译名dzz2002。然而，「单齿螺」这个译名有歧义：还有另一个螺的属也可译作「单齿螺」；但本属的台湾译名「草席钟螺属」并不会引起歧义，所以本条采取了这个译名。

**特征**
本属通常拥有厚重的圆锥状螺旋形硬壳，壳表面光滑或有螺旋凸纹，开口外缘内面有褶皱。瓷质的短轴柱坚固、呈膨大圆柱状、近基部或多或少带锯齿状，齿与基底边缘之间有方形槽沟纹。壳洞高位开口而宽阔。

**分布**
从印度洋中西部、中印半岛、马来群岛至大洋洲，包括菲律宾、日本、澳洲（北领地、昆士兰州、西澳大利亚州）等都有本属的分布。
