ABSTRACT The present revision treats most species of the genera Gavelinella , Berthelina and Lingulogavelinella . The taxa are revised, redescribed and reillustrated on the basis of type specimens, or, failing these, through topotypical material or, in the absence of any specimens, through analysis of original descriptions and illustrations. Keys for the species retained in the three genera have been generated. Many taxa recovered from Australian Cretaceous deposits are new to science. Amongst these is the oldest known gavelinellid on record, Gavelinella compacta , found in abyssal deposits from Exmouth Plateau, of Upper Valanginian age and ranging into the Hauterivian. Other new taxa are Berthelina glabra , B. petaloidea , B. pluricostata , B. pustulata , B. robusta , Lingulogavelinella minuta , L. ornata and L. semistellata . A substantial number of taxa which have been attributed to the three genera in the past, either originally or subsequently, are after discussion removed to other families or left incertae sedis . The new name Orithostella kwazuluensis is proposed to accommodate the reclassification of Lingulogavelinella frankei africana Lambert & Scheibernová, 1974. The name Anomalinoides convexus is herein validated as the original proposal of Lingulogavelinella globosa var. convexa Carter & Hart, 1977 is not available. The state of preservation of the Albian gavelinellids of New Zealand described by Stoneley prevents the critical observation of the characters necessary for generic and specific attribution. They are therefore left incertae sedis . All specimens of the gavelinellids described by Bukalova from the Albian of the Cis-Caucasus were lost during the restructuring of the V.N.I.G.N.I. in 1971: the species she proposed are therefore discussed under the incertae sedis heading. Trochammina parvula Crespin, 1944 and Gavelinella bettenstaedti Dieni & Massari, 1966 are both removed from Gavelinella and tentatively assigned to Trochammina . Gavelinella pertusa maestrichtiensis Hofker, 1956, Gavelinella tormarpensis Brotzen, 1942, Gavelinella tumida Brotzen, 1942, and Berthelina incerta (Hofker, 1957) are lectotypified.

ABSTRACT The type species of the majority of biserial toothplate-bearing genera are restudied using the SEM to investigate the morphological details of the apertural complex. A rationalisation of the classification is proposed based on overall morphology complemented by toothplate type. The Bolivinitidae are herein recognised as a family of the Buliminacea. The family is subdivided into the Bolivinitinae, Fursenkoininae, and the newly proposed Parabrizalininae and Sagrininae. The Bolivinitinae include the genera Bolivinita, Afrobolivina, Bolivina, Bolivinoides, Brizalina, Coryphostoma, Loxostomoides, Lugdunum, Sagrinella, Saidovina , and Sigmavirgulina . A neotype is designated for Bolivina plicata to stabilise the position of Bolivina , as compared to Brizalina . The genera Latibolivina and Parabolivina are synonymised into Bolivina . The Fursenkoininae include the genera Fursenkoina, Galliherina and Hopkinsinella. Details are discussed of a proposal submitted to the ICZN in order to stabilise the position of Fursenkoina in the light of the difficulties surrounding Cassidella. The species Virgulina tegulata Reuss is deemed unrecognisable. To further stabilise the position of Fursenkoina, a neotype for Virgulina squammosa is designated. The Parabrizalininae are created for the genera Parabrizalina, Euloxostoma and Loxostomina. The Sagrininae are proposed to cover the genera Sagrina, the newly proposed Alectinella, Pseudobrizalina, Virgulinopsis, and Virgulopsis. The genera Eouvigerina and Tappanina are removed to the Eouvigerinidae, while Grimsdaleinella and Zeauvigerina are removed to the Loxostomatidae, Pavoninacea. The bilamellar nature of the toothplate-like structure in Stainforthia, in conjunction with the deviating internal architecture leaves the genus incertae sedis within the Rotaliina. The genus Francesita is removed from the Caucasininae and left incertae sedis as well. Structural similarities between Francesita and Stainforthia are shown, but the creation of a suprageneric taxon to accommodate them is judged to be premature. The genus Tortoplectella is shown to be an agglutinating taxon and it is consequently removed from the Rotaliina to the Textulariina. Because of the turmoil in the classification of agglutinating forms, Tortoplectella is considered incertae sedis within the Textulariina.

ABSTRACT The type species of various ‘anomalinid’ genera have been restudied, where possible on the basis of the original types. The concepts of these taxa are discussed in the light of the new observations herein reported. The Anomalinidae comprise the genera Anomalina, Anomalinoides, Cibicidoides with Rhodanopeza as a subjective synonym, Hanzawaia, Heterolepa, Loisthostomata, Orithostella, Parrelloides and Riminopsis. The Alabamininidae are restricted to Alabamina, with Eponidoides as a subjective synonym, Charltonina, Cribroparrella, Conorotalites, Goupillaudina, Oridorsalis and Osangularia. The Gavelinellidae include Gavelinella, with Pseudovalvulineria as a subjective synonym, Angulogavelinella, Berthelina, Boldia, Co-coarota, Hansenisca, Lingulogavelinella, Notoplanulina, and Pseudogavelinella. The Cancrisidae include Cancris, Brotzenella, Cibicorbis, Gyroidinoides, with Valvalabamina as a subjective synonym, Scheibnerova, Stensioeina and Valvulineria . Gyroidina , with Serovaina as a subjective synonym, as well as Globorotalites , possess features typical of eponidid taxa, posing difficulties for its classification. The genera Nummodiscorbis, Hollandina and Holmanella are considered incertae sedis , while Gavelinonion remains a nomen inquaerendum.
