Treatment

Havelockia Pearson, 1903 View in CoL View at ENA

Havelockia Pearson, 1903: 198 View in CoL .— Panning, 1949: 466, 468.— Rowe (in Rowe & Gates), 1995: 310.

Pentathyone Clark, H. L., 1938: 458–459 View in CoL .—1946: 386, 396.— Panning, 1949: 459.

Diagnosis (after Thandar 1989). Calcareous ring short, stout, only anterior projections of radial and inter-radial plates free; posterior paired process of radial plates divided into several pieces. Body wall ossicles tables with squarish to oval discs, usually perforated by four large central and four smaller peripheral perforations, that are sometimes reduced or absent; spire of two pillars joined at apex and terminating in a few blunt teeth.

Remarks. Thandar (1989) has discussed the above generic synonymy by Panning (1949), and the replacement of the type species Havelockia herdmani Pearson, 1903 by the senior synonym Havelockia versicolor ( Semper, 1867) .
