The tabulation system proposed by Taylor (1979, 1980) and modified by Evitt (1985). There is a prepolar plate (P) and five latitudinal series of plates which, from anterior to posterior, are: polar series (A-C), preequatorial series (1-6), equatorial series (a-f), postequatorial series (I-VI), and antipolar series (X-Z). Subdivision of a primary plate may be longitudinal, from anterior to posterior [ vorne (v), medialis (m), or hinten (h)], or latitudinal, from left to right [ initialis (i), medialis (m), or ulter (u)]. The Taylor-Evitt tabulation system has been applied almost exclusively to gonyaulacaleans. Refer to Text-Figures 17-19.
