...Barry O'Connor Abstract Thirteen new radiolarian species, two new genera and one new combination from the Oligocene and early Miocene of Northland, New Zealand, are formally described. The species are: Heliodiscus tekopua (Plagiacanthidae), Valkyria pukapuka (Sethoconidae), Cyrtocapsa osculum...

... entactinarians, eight spumellarians and thirty-five nassellarians (including seventeen Plagiacanthidae). Here, we add to this total, twenty-five new forms: six spumellarians and nineteen nassellarians (including no less than sixteen Plagiacanthidae). The remaining forms will be published in a final paper...

... would be that L .? datureacornis is indeed a lophophaenid. Lamprocyrtis ? datureacornis differs from Lampromitra sinuosa Popofsky, 1913 , in its elongated cephalis, its apical opening, its lateral lobes and the shape of its upper thorax. Family Plagiacanthidae Hertwig, 1879 emend...

... are not sure if Petrushevskaya’s specimens are conspecific with ours, as the photographs are of poor quality. The number of segments and development of external wings, however, appear to differ from our material. Petrushevskaya’s material is of Paleocene age. Family Plagiacanthidae Hertwig, 1879 , emend...

... ). The highest number of species is found in the family Plagiacanthidae, with 39 taxa, of which the subfamily Lophophaeninae has 33 identified species. This includes Lophophaena buetschlii ( Pl. 4, fig. 6 ) and L. hispida ( Pl. 4, fig. 12 ), both regarded as circumtropical representatives. The subfamily...

In all, Haeckel introduced 1275 generic names (plus numerous subgeneric names), nearly an order of magnitude more than any other author in the history of radiolarian research (Radworld gives the next highest as Kozur...
