Edwards tabulation system
From dinoflaj2
The tabulation system proposed by Edwards (1990) and resulting from the labelling of the latitudinal series of plates from the cingulum towards the poles. As well as the cingular C-series, there are three series on the episome and two on the hyposome. In a polar direction, on the episome, there are the E-series, M-series and D-series; on the hyposome, there are the H-series and T-series.
