本科物種在型態學上與其他科物種的分野並不明顯，而且其螺殼的型態與分子生物學的數據並不一致。各屬所屬的物種很可能還要再調整
本科物種主要由原來捲管螺科東港捲管螺亞科（Cochlespirinae），再加入新的屬升格而成。升格後的東港捲管螺科不設亞科級分類單元。
型態描述
本科物種的體型一般都在20到30 mm左右；Nihonia maxima的體型比較大，最長可達128 mm，Aforia magnifica的螺殼甚至可達150 mm長。螺殼呈捲管狀，紡錘形，有長而尖的殼尖。 Axial sculpture is absent or feebly developed. The aperture is ovate. The columellar margin is smoot. The outer lip has a narrow profound anal sinus on the subsutural ramp。與大多數芋螺總科物種不同的是：本科物種的虹管溝通常非常直、窄和狹長。The螺厣has a terminal nucleus.
The foot of the animal is truncated anteriorly, obtuse posteriorly. The eyes are located externally near the base of cylindrical tentacles. 齒舌的齒式是1-0-R-0-1[1]。 The duplex radular teeth are nonhypodermic.
