. Bulletin of the Natural Histort Museum. Geology series. . Figs 22-25 Ceriopora rekohuensis sp. nov., thin sections, IGNS BZ 204-2. 22, partial transverse section, x 23, oblique longitudinal section showing long, curved zooidal tubes x 24, detail of longitudinal section, x 33. 25, overgrown gonozooids visible in the transverse section, x 33. Description. Colony encrusting, more-or-less circular, maxi- mum diameter mm, maximum height mm, completely adnate or the margin, slightly elevated above the substratum; mar- ginal basal lamina little apparent, mm wide where present; behind marginal lamina is a mm wide zone of autozooids and kenozooids. Autozooids without projecting peristomes, and not aligned in definite radii, although up to 3-4 non-connate apertures may occur in a radial row amongst kenozooids; apertures mm in diameter, the rim of even height all round. Kenozooid apertures 45-70% of the diameter of autozooidal peristomes, none closed by diaphragms. Brood cham- ber occupies most of colony centre, broken in the present colony; floor marked by thin layer of calcification over autozooids and kenozooids; almost none of the brood chamber roof remains ex- cept for a tiny area which indicates that thick-walled zooidal chambers may occur above the roof.
