草蓆鐘螺屬（學名：_Monodonta_），是原始腹足目鐘螺科的一屬。

拉馬克於 1801 年將本屬從林奈的鐘螺屬（_Trochus_）中分離出來，以草蓆鐘螺（_Monodonta labio_）為模式種。

本屬的學名直譯就是「單齒螺」，而這名稱也是來自中國大陸的文獻最普遍使用的譯名。然而，「單齒螺」這個譯名有歧義：還有另一個螺的屬也可譯作「單齒螺」；但本屬的台灣譯名「草蓆鐘螺屬」並不會引起歧義，所以本條採取了這個譯名。



特徵

本屬通常擁有厚重的圓錐狀螺旋形硬殼，殼表面光滑或有螺旋凸紋，開口外緣內面有褶皺。瓷質的短軸柱堅固、呈膨大圓柱狀、近基部或多或少帶鋸齒狀，齒與基底邊緣之間有方形槽溝紋。殼洞高位開口而寬闊。



分布

從印度洋中西部、中印半島、馬來群島至大洋洲，包括菲律賓、日本、澳洲（北領地、昆士蘭州、西澳大利亞州）等都有本屬的分布。
