Última Some fossil species of Babylonia seen in ultraviolet light, with description of a new species (Mollusca, Gastropoda) Naturalis Regteren, C.O. van; Gittenberger, E.. When preparing a revision of the genus Babylonia for "Indo-Pacific Mollusca", edited by Dr. R. Tucker Abbott, we tried ultraviolet light to see the outline of the colour-pattern of some fossil species. Later on we saw the same method described by Mrs. Katherine Krueger (1971). Dr. H. E. Coomans of the Institute for Taxonomic Zoology (Zoological Museum), Amsterdam, called our attention to this method. We used an ultraviolet lamp UVSL-15 of Ultra-Violet Products Inc., San Gabriel, California. Mr. Chr. Hoorn, photographer of our museum, found a method to photograph the normally invisible pattern. He used an orthochromatic film, Copex Ortho, Agfa-Gevaert, 120 din, in combination with a yellow filter. After having found a suitable specimen by previous...

In dieser Arbeit wird eine zusammenfassende Übersicht über die Spelaeodiscinae gegeben. Die bis jetzt bekannten Vertreter dieser Gruppe können in einer Gattung mit zwei Untergattungen untergebracht werden. Es handelt sich dabei um sechs Arten. Im Laufe meiner Untersuchungen sind noch sechs weitere, bisher unbeschriebene Arten bekannt geworden. Es wurde zugleich notwendig zwei neue Gattungen aufzustellen, davon eine mit zwei Untergattungen. Die Spelaeodiscinae werden zu den Pupillidae gestellt. Die Frage wie die Pupillacea in Familien und Unterfamilien aufgeteilt werden müssen wird im Rahmen einer folgenden Arbeit behandelt. Auf die Beziehungen zwischen Pupillidae und Valloniidae wird hier also nicht weiter eingegangen. Für die Sammlungen wo sich das... Tipo: Article / Letter to the editor Palavras-chave: 42.73.

The species of the Pyramidellidae collected during several expeditions in the south-eastern part of the North Atlantic Ocean are listed, with locality data, depth ranges, and notes on nomenclature, systematics and distribution. The samples classified with the genera Eulimella (partly), Anisocycla, Syrnola, Chrysallida and Odostomella are dealt with in this paper. In total 70 species are reported from the research area, 24 of which are described as new to science. A lectotype of Obeliscus gracillima Smith, 1872 (= Eulimella variabilis de Folin, 1870) and neotypes of Chrysallida multicostata (Jeffreys, 1884) and Jaminia obtusa Brown, 1827, are designated.

Vitrea trolli war bis jetzt nur von wenigen Fundorten nördlich und nordöstlich vom Garda See bekannt. Neufunde oder Bestätigungen der bei der Originalbeschreibung genannten Fundorte sind in der Literatur nicht gemeldet worden. Das Auffinden von V. trolli unweit Menton in den Alpes-Maritimes bedeutet eine Erweiterung des bekannten Verbreitungsgebietes um fast 400 km südwestwärts. Ruthenica filograna gilt rezent für eine ost- und mitteleuropäische Art. Im Pleistocän kam die Art nördlich und südlich der Alpen viel weiter westlich vor, wie die Fundorte in England und bei Menton, Frankreich, beweisen. Der neu entdeckte rezente Fundort in der Schlucht Gorge de Bergue, etwa 25 km nördlich von Menton, kann als Relikt angesehen werden. Dieses Vorkommen ist über 400...

(Mollusca: Gastropoda: Pulmonata) Naturalis Gittenberger, E.; Winter, A.J. de. Monacha (Metatheba) atacis spec. nov. is described from the French NE Pyrenees. The status of Metatheba, hitherto known from Caucasia and Asia Minor only, as well as that of other Monacha "subgenera" is discussed.

Because of its peculiar shell sculpture, with a periostracal spine on each of its many ribs, Schileykula aculeata spec, nov., described in the present paper, can easily be recognized. The species is classified with Schileykula after characters of the genitalia. Tipo: Article / Letter to the editor Palavras-chave: Orculidae; Schileykula; Taxonomy; New species; Turkey; 42.73.

Eine Chondrula der Untergattung Eubrephulus auf dem Peloponnes (Mollusca: Gastropoda: Enidae) Naturalis Gittenberger, E.. A new Chondrula species is described, most probably belonging to the subgenus Eubrephulus, viz. Chondrula (Eubrephulus) peloponnesica spec. nov. The species is known from a single locality only, situated on the SE. Peloponnesus, Greece. Shells of the other two Eubrephulus species known are figured for comparison. The distribution of the subgenus is indicated on a UTM 50 km grid map. Tipo: Article / Letter to the editor Palavras-chave: Mollusca; Enidae; Chondrula (Eubrephulus); Spec. nov.; Greece; 42.73. Ano: 1984 URL: http://www.repository.naturalis.nl/record/319353 On Cyprian Helicellinae (Mollusca: Gastropoda Pulmonata: Helicidae), making a new start Naturalis Gittenberger, E.. Our fragmentary knowledge concerning the Cyprian Helicellinae is revised and summarized, while new data are added. "Helicella (Xerotricha) conspurcata distinguenda" Haas, 1936, is a Helicopsis species that has to be called H. cypriola (Westerlund, 1889) as a consequence of the selection of a neotype for Westerlund's poorly described nominal taxon. "Helicella (Xerotricha) conspurcata arrouxi" sensu Haas, 1934 (not Bourguignat, 1863) is described as Helicella juglans spec. nov. This species stands apart among the Helicellinae by the lack of a separate penis. Neither material nor reliable records of Xerotricha conspurcata (Draparnaud, 1801) could be traced; only X. apicina (Lamarck, 1822) is known from Cyprus. The wide-spread "arrouxi" has also been found on... Tipo: Article / Letter to the editor Palavras-chave: Helicidae; Helicellinae; Taxonomy; Key; Cyprus; 42.73. Ano: 1991 URL: http://www.repository.naturalis.nl/record/318592 Wat is biodiversiteit? Naturalis Gittenberger, E.. Met de populaire term biodiversiteit wordt verwezen naar de enorme vormenrijkdom die het leven kenmerkt, van genen en eiwitmoleculen tot soorten van organismen en levensgemeenschappen. De huidige biodiversiteit is het resultaat van een zeer onregelmatig, principieel onvoorspelbaar evolutionair proces, gekarakteriseerd door tal van extreem asymmetrisch verlopende ontwikkelingen. Het toeval speelt bij de evolutie een belangrijkere rol dan regels en wetmatigheden. Naast het ontstaan van nieuwe vormen, is ook het verdwijnen, uitsterven, door geleidelijke verandering of letterlijk, min of meer incidenteel of catastrofaal, steeds een wezenlijke factor geweest. Dit kan en mag evenwel geen argument zijn om het actuele, massale uitsterven onder menselijke invloed...

The present knowledge concerning the SW European Zospeum species is summarized. Z. schaufussi Von Frauenfeld, 1862, is redescribed and compared with Z. bellesi Gittenberger, 1973, and Ζ. suaresi spec. nov. B. Gasulliella gen. nov. is introduced for Helix simplicula Morelet, 1845. A condensed synonymy list of G. simplicula is given, the shell and the genitalia of the species are described and data on its geographical distribution are presented. Helix inchoata Morelet, 1845, is made type-species of Portugala gen. nov. and dealt with in the same way as G. simplicula. A.

Ano: 1975 URL: http://www.repository.naturalis.nl/record/318664 The Genus Theba (Mollusca: Gastropoda: Helicidae), Systematics and Distribution Naturalis Gittenberger, E.; Ripken, Th. E.J.. Our knowledge concerning taxonomy and zoogeography of the fossil and recent species of the helicid genus Theba is summarized and enlarged. The fossil T. arinagae spec. nov. is described from Gran Canaria. The recent T. andalusica spec. nov. and T. sacchii spec. nov. are described from the southernmost part of the Iberian peninsula and the southernmost part of Morocco, respectively. This implies that four fossil and ten recent Theba species are recognized. Two of the fossil species are very insufficiently known. Some recent species are polytypic, which results in 17 (sub)specific taxa in total. Neotypes are selected for T. subdentata legionaria and T. solimae. The nominate subspecies of T. pisana is shown to be aberrant because of its very wide range; the...

Taxonomic and biogeographic data on Babylonia and Zemiropsis, published after the 1981 monograph on Babylonia by Altena & Gittenberger, are summarized and new data are added. Babylonia and Zemiropsis are characterized and considered most closely related genera. Babylonia lani spec. nov. and Babylonia umbilifusca spec. nov. are introduced as new to science. Babylonia leonis Altena & Gittenberger, 1972, described from pliocene-pleistocene deposits, is reported as an extant species. The enigmatic “Babylonia” rosadoi is considered a Zemiropsis species on the basis of both shell morphology and distribution.

In der Gattung Trissexodon Pilsbry gehören nach Pilsbry (1895: 288) und späteren Autoren die beiden rezenten Arten T. constrictus (Boubée) und T. quadrasi (Hidalgo). Wenz (1923: 457-458) wählte T. constrictus zur Typusart und stellte zugleich noch zwei fossile Arten, T. subconstrictus (Souverbie) und T. plioauriculatus (Sacco), in derselben Gattung. Germain (1929: 205) hat darauffolgend T. plioauriculatus zur Typusart einer neuen Gattung Protodrepanostoma gemacht. In dieser Gattung rechnete er auch P. planorbiformis (Sacco), ebenfalls eine fossile Art. Zilch (1960: 694) betrachtete schliesslich Protodrepanostoma als jüngeres Synonym von Trissexodon. Eine anatomische Untersuchung der beiden rezenten Arten hat ergeben, dass diese durchaus nicht nahe verwandt... Tipo: Article / Letter to the editor Palavras-chave: 42.75.
