Pustulopora zealandica Mantell, 1850, by original designation; Recent, New Zealand. GORDON AND TAYLOR Family ENTALOPHORIDAE Auctt. lAttinopora sp. Material. NHM BZ 4771^772. Fie. 5 Description. Colony erect, with narrow, cylindrical branches, mm in diameter, strongly curved in one specimen; bifurca- tions assumed to exist but not observed. Autozooids large, fixed-walled, frontal walls flat and minutely pseudoporous, about mm long; zooidal boundaries not prominent; autozooids dis- posed in annular to irregularly spiral patterns with about 7 zooids around the branch circumference; apertures subcircular or slightly elongate longitudinally, mm in diameter. Remarks. With only two small specimens available, it is impossi- ble to be certain of the generic identity of this species. There are several genera of vinculariiform tubuliporines to which it may potentially belong, , Diaperoecia,Mecynoecia, Entalophoroecia. However, the large size of the zooids and their arrangement on the colony surface, together with the biogeographical provenance, prompt a tentative identification as the cinctiporid genus Attinopora. Like other cinctiporids, gonozooids have never been observed in Attinopora, but a much larger suite of specimens would be needed for their absence to be reasonably established in the Red Bluff Tuif species.
