ABSTRACT

Foraminifera were examined from the top centimeter of 378 gravity core bottom samples (with samples from a few additional depths in some of the cores), and bottom grab and dredge samples. The samples were collected from numerous traverses made in the Timor Sea in 1960 and 1961, from Australia across the Sahul Shelf and Timor Trough to Timor and the adjacent islands of Roti and Leti, and from depths of 20 to nearly 3,500 meters.

A total of 946 species are described and illustrated, representing 127 foraminiferal families (two new), 118 subfamilies, 428 genera (12 new), and 944 species (101 new). In addition, two new genera and species of incertae sedis are described. New taxa are the agglutinated Placopsilina bifurca, Barbourinella teretis, Liebusella improcera, Textulariella parvacycla, Karreriella pseudowrighti, Bigenerina aspratilis, Plotnikovina timorea, the porcelaneous Glomulina rotiensis, Nubeculinita ramosa, Spirophthalmidium prolixum, S. scabrum, Kalosha aluta, new genus Mikrobelodontos, type Spiroloculina bradyi Barker, Spiroloculina abatholopa, Ammomassilina clypeoarenula, new genus Falsagglutinella, type F. byrsa, F. angularis, Pseudoflintina laculata, Massilina timorensis, Quinqueloculina adiazeta, Q. ectypha, Q. latidentella, Q. vandiemeniensis, Miliolinella heligmateira, M. obstipacella, M. quinquangula, Triloculina triquetrella, Triloculinella chiastocytis, T. parisa, Sigmoilopsis revetocollaris, new genus Euthymonacha, type Monalysidium politum Chapman, E. leura, the Lagenida Dentalina ruidarostrata, D. semiinornata, Enantiodentalina timorensis, Grigelis orectus, Nodosaria timorensis, Saracenaria stolidota, Siphomarginula angulosa, Spincterules compressus, Amphicoryna leurodeira, A. meringella, Astacolus paucacostatus, Marginulina paeminosa, Vaginulinopsis gnamptina, Cerebrina serangodella, Conolagena polystroterina, Lagena annellatrachia, L. kermatoina, Pygmaeoseistron annulatacollare, P. cyrillion, P. treptoinum, Reussoolina stellula, R. strangeri, R. trachiella, Globulina acocebathra, Sigmomorphina beaglensis, Ramulina angusta, R. confossa, R. vanandeli, Exsculptina glaphyraheda, E. athyrmata, Favulina colubrosacosta, Galwayella trixopteryx, Oolina baukalionilla, O. kleithria, O.parisoina, O. stiktosa, Duplella trinalimarginata, Fissurina deuterolegna, F. infimabrocha, Lagenosolenia duplicimarginata, L. laciniosa, L. peltatusella, L. physamorphina, L. strigimarginata, Pseudofissurina konara, Nanosylvanella pattersoni, Pytine lemniscata, the Robertinida Saintclairoides toreutus, the planktonic Tenuitella kyrtomina, Globigerinoidesella bollii, and Globoturborotalita decorata, the Buliminida new genus Aphelophragmina, type Textularia variabilis var. spathulata Williamson, new family Cheilochanidae, new genus Cheilochanus, type C. minutus, Heterocassidulina saidovae, Cassidelina sgarrellae, Loxostomina costatapertusa, Rectobolivina akainophera, new genus Alassoida, type Sagrina virgula Brady, Bulimina acaenapeza, the Rotaliida new family Neoeponididae, Rosalina cosymbosella, Glabratellina traphera, Siphoninoides diphes, new genus Facetocochlea, type Pulvinulinella pulchra Cushman, new genus Poroepistominella, type P. sahulensis, Pseudoparrella zhengae, new genus Prionotolegna, type P. paeminosa, Planulinoides polymitarius, Discorbinella serangodes, new genus Orbiculoris, type O. tubulorictus, Carpenteria polythylakina, new genus Patagiatella, type Epistomariella milletti Collins, Nonion grossepertusum, Resigia quadrata, Alabamina achanes, Anomalinoides rotiensis, and new genus Cristatavultus, type Elphidium pacificum Collins.
