扁螺科

**齒輪螺科**（學名：Tornidae），是玉黍螺目的一個科級海洋腹足綱軟體動物，其物種皆為體型非常細小的有螺厴海螺。此外，Iredale 認為本科亦應包括原來屬於**扁螺科**（Adeorbidae Monterosato, 1884）的物種。

根據 ITIS，現時屬於齒輪螺科的屬，除了齒輪螺屬以外，其他的全屬玻璃螺科（Vitrinellidae Bush, 1897）:61。玻璃螺科過往在 2005 年的分類曾被認為是齒輪螺科的異名，但在 2017 年的分類又再分別出來。

## 形態描述

本科物種皆為微小貝，無色，呈玻璃狀。螺殼扁平，有臍孔，耳狀。殼口傾斜；有螺厴，角質，有偏心核。螺殼有簡單的小螺柱，圓形，外唇尖。

本科物種的身體與鐘螺科的物種不同：其腹足沒有帶狀附肢。齒舌屬於紐舌型。

## 分類

### 2005 年分類

根據 2005 年《布歇特和洛克羅伊的腹足類分類》，本科可分為以下四個亞科：

* Circulinae Fretter & Graham, 1962
* Torninae Sacco, 1896 (1884)
* Teinostomatinae Cossmann, 1917
* 玻璃螺亞科（Vitrinellinae Bush, 1897）:61

不過後來這些亞科都被視為「另類表達形式」。

這四個亞科所包括的屬如下：
