本文描述在台灣基隆北方海域始新世地層中發現的甲藻類缺網紋化石藻科（Areoligeraceae）。Areoligera屬共計一種：台灣缺網紋藻（Areoligera taiwaniana C. L. Shaw），Cyclonephelium屬共計二種：彭佳嶼雜紋架藻（Cyclonephelium pengchiahsum C. L. Shaw sp. nov.）以及台灣雜紋架藻（Cyclonephelium taiwanianum C. L. Shaw sp. nov.），Glaphyrocysta屬共計一種：小窗紋聯刺胞囊藻（Glaphyrocysta microfenestrata(Bujak) Stover & Evitt）。

Three genera Areoligera, Cyclonephelium and Glaphyrocysta, the fossil dinoflagellate cysts of Areoligeraceae, obtained from Eocene sediments offshore of Keelung area in northern Taiwan are reported. One species of the genus Areoligera (Areoligera taiwaniana C. L. Shaw), two species of the genus Cyclonephelium (Cyclonephelium pengchiahsum C. L. Shaw sp. nov. and Cyclonephelium taiwanianum C. L. Shaw sp. nov.) and One species of the genus Glaphyrocysta (Glaphyrocysta microfenestrata (Bujak) Stover & Evitt) are described.
