BRYOZOANS FROM CHATHAM ISLAND 19 obscuring interzooidal boundaries; in the poorly-preserved material at hand these appear to be elongate-oval, with a single central foramen surrounded by a concentric granular cryptocyst. Ovicell endozooidal, immersed under the succeeding cryptocyst, the more- or-less semicircular opening occurring immediately distal to the opesia-orifice. Remarks. The single tiny specimen, imperfectly preserved, com- prises only three complete zooids, all fertile, with parts of adjacent broken zooids. Most of the diagnostic characters are present but the generic attribution is uncertain. Aechmella Canu & Bassler, 1917 seems ruled out, as the interzooidal avicularia of the type species are relatively large and distinct with acute rostra Hoplitaechmella species have numerous small avicularia, occasional vicarious avicularia, and endozooidal ovicells as in the present material but distinct oral-spine bases occur in the type and other species (see Voigt 1949; Berthelsen 1962). Known species include: H. antecedens (Brydone, 1914), Upper Senonian, England H. deshayesi (von Hagenow, 1851), Upper Senonian, The Nether- lands H. nitescens (Brydone, 1914), Upper Senonian, England H. nonna (von Hagenow, 1839), Upper Senonian, Germany H. smitti (Hennig, 1892), Danian. Sweden and Denmark H. vespertilio (von Hagenow, 1839), Upper Senonian, Germany H. vespertilioides Berthelsen, 1962, Upper Danian, Denmark. If the present material is Hoplitaechmella, then it represents the first known occurrence of the genus outside Europe, and the young- est stratigraphical record. Microporid sp. Material. IGNS BZ 209, Chatham Island. Figs 43, 44 a unique specimen from Pukekio, Description. Specimen erect, apparently slightly worn, compris- ing part of a narrow bilamellar branch, mm long and up to mm wide. Zooids sub-elongate, widest in the middle, tapering distally and proximally, length = mm, width
