This represents the first report of a benthic cerianthid from South African waters. The cnidom and anatomy of other known species of Ceriantheopsis Carlgren are compared with those of the new species, the distributions of the species are mapped and a key provided to their identification. <![CDATA[<b>Micromammals in the Northern Cape Province of South Africa, past and present</b>]]> This paper provides a basis for conservation work by detailing the micromammalian taxa occurring in the Northern Cape Province. It presents new evidence from 30 barn owl pellet collections, augmented by previously published material from trapping or observation (here called 'conventional' reports) and owl roosts, divided into pre-1930, 1930-1979 and 1980 and newer as an indication of continuity of occurrence. A historical perspective is added by the inclusion of material from two archaeological sites dating to the Pleistocene (before about 10 000 years ago) and || from the Holocene (after about 10 000 years ago). Northern Cape Province synonymies are provided as an aid to equating older records with modern taxonomy. In all, 77 currently recognized micromammalian species have been recorded from the province. These comprise five Afrosoricida (golden moles), six Macroscelidea (elephant shrews), eight Soricomorpha (forest shrews), 16 Chiroptera (bats), and 42 Rodentia (rodents). <![CDATA[<b><i>Hoplitoplacenticeras </i></b><b>(<i>H</i>.) <i>howarthi</i> Collignon, 1970 (Cephalopoda: Ammonoidea) from KwaZulu-Natal, South Africa and Madagascar; intraspecific variation, dimorphism and affinities</b>]]> Additional specimens of the Campanian ammonite Hoplitoplacenticeras (H.) howarthi Collignon, 1970, as well as examination of Collignon's (1970) Madagascar! specimens of Hoplitoplacenticeras allow us to discuss the intraspecific variation, probable dimorphism and affinities of the species. <![CDATA[<b>The Upper Cretaceous ammonite <i>Grandidiericeras</i> Collignon, 1961 (Puzosiinae), from the St Lucia Formation of KwaZulu-Natal, South Africa</b>]]> The ammonite genus Grandidiericeras Collignon, 1961 was previously known from two species, based on six described specimens, three of which, referred to Grandidiericeras grandidierorum Collignon, 1961, are from the Middle Campanian of Madagascar, and three, referred to Grandidiericeras nagaoi Matsumoto & Saito, 1987, from the Coniacian of Japan. A single specimen from the Upper Santonian to Lower Campanian of Lake St Lucia in KwaZulu-Natal represents a new species, Grandidiericeras corrugatum. <![CDATA[<b>Cretaceous faunas from Zululand and Natal, South Africa. The ammonite genus <i>Oxytropidoceras</i> Stieler, 1920</b>]]> Ten species of the distinctive oxycone ammonite Oxytropidoceras are described from the Middle and lower Upper Albian Mzinene Formation of northern KwaZulu-Natal. Oxytropidoceras (O.) alticarinatum (Spath, 1922) was originally described from western Europe. O. (Manuaniceras) manuanense (Spath, 1921), O. (M.) falcatum sp. nov. and O. (Venezoliceras) umsinenense (Van Hoepen, 1931) are only known from northern KwaZulu-Natal. The following species were previously recorded from Madagascar: O. (O.) basseae (Besairie, 1936), O. (O.) hoepeni Collignon, 1936, O. (Adkinsites) multituberculatus Collignon, 1936, O. (Mirapelia) hourcqi Collignon, 1936, and O. (M.) colcanapi Collignon, 1936. O. (Venezoliceras) madagascariense Collignon, 1949, was recorded from Madagascar, southern Mozambique and Venezuela.
