aminiferal Research, 2001, 31(4): 294-308 6 图版 .Two sections of Epiligurian sediments(Northern Apennines, Italy) covering thechronostratigraphic interval from the MiddleEocene to the Lower Miocene were analyzed fortheir foraminiferal content. Several specimensbelonging to 25 selected species of agglutinatedforaminifera were analyzed using the energydispersivex-ray spectrometry (EDS) method.The collected data show how these species areselective in composition, size, and shape of theagglutinated grains and cement composition.Test microstructures can be subdivided into fourgroups:– microstructure I: silica cement anddominant quartz and feldspar grains,– microstructureII: indistinct siliceous mass withoutagglutinated grains,– microstructure III: abundantcalcite cement, fine-grained texture, andgrains selected for size and composition,– microstructureIV: scarce calcite cement, a coarsegrainedtexture and non-selected grains. A relationshipbetween test microstructure and paleobathymetricconditions for the Monte Piano Marl,Ranzano Sandstone, and Antognola Marl Formationswas observed. An almost exclusive presenceof agglutinated taxa showing microstructuresI and II characterized the "facies varicolori"of the Monte Piano Marls (lower-middlebathyal depths, from 2000 m to 1000 m). Asharp increase in species showing microstructuresIII and, subordinately, IV characterized theoverlying lithostratigraphic units ("facies grigia"of the Monte Piano Marls, Ranzano Sandstonesand Antognola Marls) whose paleobathymetrydecreases upwards (middle-upper bathyal up toslope/shelf break from 1000 to 200m).2008040249来 自 于 特 提 斯 域 的 新 属 种 Charliella rossae—晚 二 叠 世 双 列 虫 演 化 的 评 述 = Charliella rossaen. gen.,sp., from the tethyan realm:remarkson the evolution of Late Permian Biseriamminids.( 英 文 ). Altiner D; Sevinç Özkan-Altiner.Journal of Foraminiferal Research, 2001, 31(4):309-314 1 图 版 .The name Charliella is proposed for a newbiseriamminid genus characterized by a fourlayeredwall that thickens along the anterior sideof the septa and partially occludes the chambercavity. Charliella rossae was derived from theGlobivalvulina graeca-Globivalvulina vonderschmittilineage which also constituted the rootstock of true Paraglobivalvulina (P. mira) in LatePermian time. The Globivalvulina decrouezae-Septoglobivalvulinagracilis-Paraglobivalvulinoides septulifer lineage is anothertrend in the evolution of biseriamminids.The recognition of such a lineage in the LatePermian necessitates taxonomic revision of thebiseriamminids to attribute globular and involuteforms with thin and undifferentiated walls toSeptoglobivalvulina, a genus which was synonymizedunder Paraglobivalvulina in previouswork.2008040250有 孔 虫 Rotorbinella Bandy, 1944 属 和 它 的 分类 = The genus Rotorbinella bandy, 1944 and itsclassification. ( 英 文 ). Revets S A. Journal ofForaminiferal Research, 2001, 31(4): 315-318 1图 版 .The study of the type series of Rotorbinellacolliculus Bandy, 1944, shows the presence ofcoverplates and thus confirms the rotaliaceannature of Rotorbinella. Notwithstanding preservationaldefects, Rotorbinella can now be distinguishedconsistently from the many genera withwhich it has been confused in the past.2008040251新 种 Cocoarota madrasensis Rajeshwara Raoand Revets n. sp.— 来 自 于 印 度 马 德 拉 斯Bengal 海 湾 内 陆 架 的 一 个 新 的 有 孔 虫 种 类 =Cocoarota madrasensis Rajeshwara Rao and Revetsn. sp.-a new foraminiferal taxon from theinner shelf of the bay of Bengal, off madras, India.( 英 文 ). Rao N R; Periakali P. Journal ofForaminiferal Research, 2001, 31(4): 319-323 1图 版 .Detailed examination of inner shelf sedimentsof the Bay of Bengal, off Karikkattukuppam,south-east coast of India near Madras, revealedquite a few rarely recorded or hitherto unidentifiedtaxa. Of these, one species is a living representativeof the genus Cocoarota Loeblich andTappan, considered to be extinct since the Eocene.The few existing records of this genusfrom the Upper Eocene, exclusively from theAmerican region, and lack of subsequent ones,raise questions with regard to its geographicaldistribution and possible migration since the Eocene.Cocoarota madrasensis n. sp. RajeshwaraRao and Revets is a calcareous, densely perforate(except for the apertural face and sutures),foraminifer characterized by the presence of aseries of irregularly shaped bosses clustered inthe depressed umbilical area, resembling spiralizedornamentation as a result of thickening offolia and inner ends of sutures of earlier whorls.The flaps or folia on the umbilical side hoverover the umbilical aperture that remains open inthe earlier parts of the test. It is one of the moreabundantly occurring species on the inner shelfoff Madras (now Chennai), associated with considerablenumbers of Asterorotalia trispinosa(Thalmann) and A. inflata (Millett), particularlyat depths between 38 and 55m, and on substrate80
