The author describes an anomalous specimen in diatom Coscinodiscus oculus-iridis Ehr., 1839, caught from Guanabara Bat, (22º 51' 8" Lat. S. - 43º 14' 3" Long. W. G.); its dorsal face (fig. 1), is different from the ventral one, (fig. 2).

A description of Physa cubensis Pfeiffer, 1839, based on 15 speciments collected in Havana, Cuba, is presented. The shell, measuring 9.0 x 4,8mm to 12.3 x 6.4mm, is ovate-oblong, thin, diaphanous, horncolored, shining. Spire elevated, broadly conical; protoconch distinct, roundish, reddish-brown. About five moderately shouldered, roundly convex whorls, penultimate whorl expanded; spiral striation subobsolete; growth line faint on the intermediate whorls, clearly visible on the body whorl, crowded here and there. Suture well impressed. Aperture elongated 2.05 - 2.67 (mean 2.27) times as long as the remaining length of the shell, narrow obovulate-lunate; upper half acute-angled, lower half oval, narrowly rounded at the base; outer lip sharp, inner lip completely closing the umbilical region; a thick callus on the parietal wall; columellar plait well marked. Ratios: shell width/shell length - 0.52-0.61 (mean 0.55); spire length/shell length = 0.27 - 0.33 (mean 0.31); aperture length/shell length = 0.67 - 0.73 (mean 0.69). Oral lappets laterally mucronate; foot spatulate with acuminate tail. Mantle relection with 6 - 8 short triangular dentations in the right lobe (columellar side) and 4 - 6 in the left lobe (near the pneumostome). Renal tube tightly folded into a zigzag course. Ovotestis, ovispermiduct, seminal vesicle, oviduct, nidamental gland, uterus and vagina as in Physa marmorata (see Paraense, 1986, Mem. Inst. Oswaldo Cruz, 81: 459-469). Spermathecal body egg-shaped or pear-shaped; spermathecal ducta uniformly narrow with expanded base, a little longer than the body. Spermiduct, prostate and vas deferens as in P. marmorata (Paraense, loc. cit.). Penis wide proximally, narrowing gradually apicad; penial canal with subterminal outlet. Penial sheath following the width of the penis and ending up by a bulbous expansion somewhat narrower than the proximal portion. Penaial sheath/prepuce ration = 1,25 - 1,83 (mean 1.49). Prepuce much wider than the bulb of the penial shealth, moderately shouldered owing to the intromission of the bulb, and with a large gland in one side of its proximal half occupating about a third of its length. Extrinsic muscles of the penial complex as in P. marmorata. Jaw a simple obtusely V-shaped plate. Radula to be described separetely.

Neohilgertia gen. n. proposed for Oxyuridae nematodes from Thylamys venustus cinderellus (Marsupialia: Didelphidae) is described. The hypothesis about the possibility of a secondary parasitism for marsupials and the origin of the genus in the African Sciuridae parasite ancestors is discussed.

(Résumé de l'ouvrage) Die RGG4 bietet in 15 665 Artikeln und Teilartikeln einen fundierten Überblick über Religion und Religionen, wie sie gelebt und gedacht wurden und werden. Sie bietet den neuesten Forschungsstand, dargestellt von 3 972 ausgewiesenen Kennern der jeweiligen Materie aus 74 Ländern. Die RGG4 führt die Tradition der ersten drei Auflagen fort: Aus der Mitte des evangelischen Glaubens ist weit mehr als die Theologie im Blick, nach deren Kriterien wird aber gewichtet.Die RGG4 erschließt die Themen in Form von biographischen Artikeln, Länder-, Orts-, Begriffs- und Ereignisartikeln sowie Artikeln über Gruppierungen und Institutionen. Knappe Definitionsartikel und Querverweise erleichtern die schnelle Information. Ausführliche Reihenartikel behandeln Stichworte wie "Abendmahl" oder "Christentum" aus vielerlei Perspektiven. Die RGG4 ist durch die Artikelvielfalt und die detailgenaue Darstellung ein Nachschlagewerk; zugleich ist sie eine Lehr- und Repetitionsbibliothek. Sie bringt mit einem ausgesucht lesbaren Schriftbild ein Maximum an Information auf einer Seite. Die acht Bände der RGG4 decken jeweils ganze Buchstaben ab. Der das Werk abschließende Registerband ermöglicht den Zugang zu dem in der RGG4 enthaltenen Wissen nach noch spezielleren Fragestellungen wie beispielsweise Namen und Stichworten, die keinen Haupteintrag haben. Selbstverständlich ist die RGG4 auf alterungsbeständigem Papier gedruckt, solide fadengeheftet und in Buckramleinen gebunden. Die RGG4 erhielt von der Stiftung Buchkunst die Auszeichnung "Eines der schönsten Bücher 1998. Vorbildlich gestaltet in Satz, Druck, Bild und Einband."

We report the generation and analysis of functional data from multiple, diverse experiments performed on a targeted 1% of the human genome as part of the pilot phase of the ENCODE Project. These data have been further integrated and augmented by a number of evolutionary and computational analyses. Together, our results advance the collective knowledge about human genome function in several major areas. First, our studies provide convincing evidence that the genome is pervasively transcribed, such that the majority of its bases can be found in primary transcripts, including non-protein-coding transcripts, and those that extensively overlap one another. Second, systematic examination of transcriptional regulation has yielded new understanding about transcription start sites, including their relationship to specific regulatory sequences and features of chromatin accessibility and histone modification. Third, a more sophisticated view of chromatin structure has emerged, including its inter-relationship with DNA replication and transcriptional regulation. Finally, integration of these new sources of information, in particular with respect to mammalian evolution based on inter- and intra-species sequence comparisons, has yielded new mechanistic and evolutionary insights concerning the functional landscape of the human genome. Together, these studies are defining a path for pursuit of a more comprehensive characterization of human genome function.
