V. MELVILLE (Assistant Secretary, International Commission on Zoological Nomenclature) Professor J. Chester Bradley's draft English text of the Rules, Article 24, deals with the question of homonymy between names in the same group, that is with homonymy between specific and subspecific names within a single nominal genus, between generic and subgeneric names, and between names within the Family-group, or within the Order/Class-group or within the Phylum- group as the case may be. Brief reference is also made, in Section 7 of the Article, to the question of homonymy between names at different levels, as when, for example, a generic name and a name in the Order/Class-group are found to consist of identical words. 2. The question of homonymy between names at different taxonomic levels was considered by the Thirteenth International Congress of Zoology at Paris in 1948 (Bull. zool. Nomencl. 4 : 164) in connection with Opinion 102 and with special reference to the ordinal name Siphonophora Eschscholtz, 1829 and the generic name Siphonophora Koch, 1855. The Congress then ruled " that words should be inserted in the Ragles to make it clear that the Law of Homonymy does not apply as between generic or trivial names on the one hand and the names of units belonging to categories above the family level on the other, and therefore, that, where such a name consists of a word which has already been used as the name of a unit of sub-ordinal or higher category that name is not to be rejected as an invalid homonym ". The purport of this ruling is incorporated in Article 24, section 7 of the draft English text. The Paris Congress added a Recommendation " deprecating the selection as generic uuu Original from and digitized by National University of Singapore Libraries 1094 Bulletin of Zoological Nomenclature or trivial names of words previously published as the names of units of sub- ordinal or higher category ". This Recommendation is incorporated in Article 10, Recommendation 9(/3) (for generic names) and 15 (for specific names) of the draft English text (Bull, 14 : 81-82). 3. No mention was made by the Paris Congress, nor is any to be found in Professor Bradley's draft, of possible homonymy between names in the Pamily-group on the one hand and names at lower levels on the other except in so far as the use of names terminating in -idae and -inae was prohibited in all groups except in families and sub-famihes respectively. This is the only provision at present in the Regies (although omitted from Professor Bradley's draft) which prescribes standard terminations for taxa of particular categories while prohibiting the use of those terminations for any other category. This provision must certainly be re-examined by the London Colloquium in the light of the Copenhagen Decision to include subtribes, tribes and superfamilies1 in the Family-group of taxa, for since there is no scheme of prescribed terminations for these categories, so there is no provision dealing with homonymy between the names of taxa in these categories and generic and specific names. 4. Instances of homonymy between names in the Family-group and generic names were brought to the notice of the Commission by Mr. D. E. Kimmins (British Museum (Natural History), London) in two letters dated 12th May 1954 and 11th July 1956. In the first of these letters Mr. Kimmins raised the question of the use of unchanged generic names to designate " Sections " of the Family ebhemebidae by Eaton in 1883-1888 (Trans. Linn. Soc. [2] Zool. (3)). According to Mr. Kimmins, the Family ephemebidae as understood by Eaton was equivalent to the modern Order Ephemeroptera, and his " Sections " had acquired general acceptance as subfamilies or families, with correctly formed names and with authorship and date as from Eaton's use of the unchanged generic names to designate " Sections ". The Copenhagen Congress decided (Copenhagen Decisions : 36, Decision 33(1)) that " a Family- group name was to be accepted as acquiring availability and as ranking for priority from the date of its original publication, irrespective of whether it was then published with one of the terminations now prescribed or currently accepted, provided that it is clear that the term concerned was used to denote a suprageneric category and was not employed merely as a plural noun or adjective ". Mr. Kimmins asked whether this rule would cover cases of Family group names published with no termination added to the stem of the name of the type-genus, as with Eaton's name for " Sections ". While it seems unlikely that this contingency was envisaged by the Copenhagen Collouium, it seems clear that such a conclusion is not expressly excluded, and that a case can be made out for the establishment of current practice in the order Ephemeroptera in the interests of stability of nomenclature. 1 The question of the transfer of the superfamily category frcm the family-group to the Order/Class-group is discussed in Document 59/1 see p. 1035 above. Original from and digitized by National University of Singapore Libraries Bulletin of Zoological Nomenclature 1095 5. In his second letter, Mr. Kimmins drew attention to the homonymy existing between the generic name Lestoidea Tillyard, 1913, and a superfamily name based on the generic name Lestes, Leach, 1815, which, if formed in accordance with the practice prevailing

E-Mail: [email protected] Zusammenfassung Die Kenntnis der Brachiopoden der Préalpes romandes in der Südwestschweiz (Kantone Bern, Freiburg und Waadt), des fränzösi- schen Chablais und der Klippenregion der Zentralschweiz beruht zum grossen Teil auf den klassischen Arbeiten früherer Autoren. Die Brachiopoden kommen fast ausschliesslich in der Klippendecke (Préalpes médianes) vor. Die Klippendecke besteht aus einer nahezu lückenlosen Abfolge von mesozoischen Sedimenten. In fast allen stratigraphischen Stufen kommen Brachiopoden vor, doch mit unter- schiedlicher Häufigkeit und Frequenz. In der vorliegenden Arbeit werden über 60 Arten der Ordnungen Rhynchonellida, Spiriferinida und Terebratulida diskutiert. Zwei neue Arten (Septaliphoria felberi nov. sp., Aulacothyris maendlii nov. sp.) aus dem Dogger der My- then werden beschrieben. Obwohl die von älteren Autoren aufgestellten Arten neu untersucht und teilweise revidiert werden müssen, ist der besondere Charakter dieser Brachiopoden offensichtlich. In der Trias lassen sich die Brachiopoden mit Vorkommen in ganz Europa vergleichen. Im späten Dogger und Malm zeigen sich deutliche Analogien zu Formen der Ost- und Südalpen. Die Brachiopoden der Mytilus-Schichten sind eher endemisch. Im frühen und mittleren Lias erscheint eine gemischte Fauna mit Arten aus Jura und Alpen. Diese Affinitäten passen recht gut in den gegebenen tektonischen Rahmen: nach der Trennung des Kontinents Pangaea in einen euro- päischen Nord- und afrikanischen Südteil am Ende der Trias entstanden in der Bruchzone Mikrokontinente (Ostalpen, Briançonnais).

  • Binomial Nomenclature and Classification
    FACULTY OF AGRICULTURAL SCIENCES AND ALLIED INDUSTRIES INTRODUCTORY BIOLOGY UGR-121 Binomial nomenclature and Classification LECTURE- 03 NOMENCLATURE Nomenclature is giving distinct scientific names to various structures including living organisms for their identification. The names are of two types - vernacular (common name) and scientific names. The vernacular names are based on some peculiarity of the organisms, e.g., Kandali (a plant having spines). Scientific names are distinct and specific, they have particular spellings which are not changed. TYPES OF NOMENCLATURE Three types of nomenclature are polynomial, binomial and trinomial. POLYNOMIAL SYSTEM According to this system, name of any plant consists of many words. For e.g., Caryophyllum saxatilis folis gramineus umbellatus corymbia which means Caryophyllum growing on rocks, having grass like leaves and umbellate corymb flowers. BINOMIAL SYSTEM Carolus Linnaeus used this nomenclature system for the first time and proposed scientific name of all the plants and animals. He is the founder of binomial system. Linnaeus proposed scientific name of plants in his book "Species plantarum". In binomial nomenclature, each scientific name has 2 components - generic name (genus) and specific name (species). E.g., Solanum tuberosum (potato), Mangifera indica (mango) The name indicates relationship of a species with others present in the same genus. TRINOMIAL SYSTEM This system was proposed by Huxley and Stricklandt. According to this system, name of any plant or species is composed of three names- Subspecific name (Name of variety) When members of any species have large variations then trinomial system is used. On the basis of Generic name Specific name dissimilarities, this species is classified into sub-species.

  • Diversity Dynamics of Early–Middle Jurassic Brachiopods of Caucasus, and the Pliensbachian–Toarcian Mass Extinction
    Diversity dynamics of Early–Middle Jurassic brachiopods of Caucasus, and the Pliensbachian–Toarcian mass extinction DMITRY A. RUBAN Ruban, D.A. 2004. Diversity dynamics of Early–Middle Jurassic brachiopods of Caucasus, and the Pliensbachian– Toarcian mass extinction. Acta Palaeontologica Polonica 49 (2): 275–282. Taxonomic diversity of NW Caucasus brachiopods changed cyclically in the Early–Middle Jurassic. Diversifications took place in the Late Sinemurian–Early Pliensbachian, Middle–Late Toarcian and Late Aalenian–Early Bajocian, while diversity decreases occured in Late Pliensbachian–Early Toarcian, Early Aalenian and Late Bajocian. Outstanding diver− sity decline in the Late Pliensbachian–Early Toarcian corresponds to a global mass extinction interval, whose peak has been documented in the Early Toarcian. Similar diversity changes of brachiopods are observed in other Tethyan regions, including the well−studied Bakony Mountains, although in NW Caucasus the recovery after demise have begun earlier. The causes of Pl−To mass extinction in the studied region are enigmatic. Probably, it could be linked to anoxia, but its cor− respondence to the beginning of transgression is not coincident with the global record, so eustatic causes seem to be doubtful for this region. Key words: Brachiopoda, taxonomic diversity, mass extinction, Jurassic, Caucasus, Russia. Dmitry A. Ruban [ruban−[email protected]], Geology−Geography Faculty, Rostov State University, Zorge st., 40, Rostov−na− Donu, 344090, Russia; correspondence address: Tchistopolskaja st., 3, App. 10, Rostov−na−Donu, 344032, Russia.

  • Unit: II 2.1. Taxonomic Ranks and Categories a Given Rank Subsumes Under It Less General Categories, That Is, More Specific Descriptions of Life Forms
    P a g e | 1 M.Sc.1st Semester; Course Code: Zoo-01-CR; Unit: II 2.1. Taxonomic ranks and categories A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of traits or features from common ancestors. The rank of any species and the description of its genus is basic; which means that to identify a particular organism, it is usually not necessary to specify ranks other than these first two. Consider a particular species, the red fox Vulpes vulpes: its next rank, the genus Vulpes, comprises all the 'true foxes'. Their closest relatives are in the immediately higher rank, the family Canidae, which includes dogs, wolves, jackals, all foxes, and other caniforms such as bears, badgers and seals; the next higher rank, the order Carnivora, includes feliforms and caniforms (lions, tigers, hyenas, wolverines, and all those mentioned above), plus other carnivorous mammals. As one group of the class Mammalia, all of the above are classified among those with backbones in the Chordata phylum rank, and with them among all the animals in the Animalia kingdom rank. Finally, all of the above will find their earliest relatives somewhere in their domain rank Eukarya. The International Code of Zoological Nomenclature defines rank as: The level, for nomenclatural purposes, of a taxon in a taxonomic hierarchy (e.g. all families are for nomenclatural purposes at the same rank, which lies between superfamily and subfamily) Main Ranks `In his landmark publications, such as the Systema Naturae, Carolus Linnaeus used a ranking scale limited to: kingdom, class, order, genus, species, and one rank below species.

  • Evidence for a Stratigraphic Basis for the Anthropocene
    Evidence for a Stratigraphic Basis for the Anthropocene Colin N. Waters, Jan Zalasiewicz, Mark Williams, Simon J. Price, Jon R. Ford and Anthony H. Cooper Abstract The Anthropocene was proposed as a term (Crutzen and Stoermer 2000) before consideration was given to the nature of the key signatures, contrasting with standard procedures for defining such units. The term is being widely used in both popular and scientific publications before a decision is made as to whether it warrants formalisation and definition of a Global Stratigraphic Section and Point (GSSP). The deliberate human modification of the landscape and its subsurface, and the creation of human-generated novel sedimentary deposits, minerals, and landforms, are characteristic features of the development of Earth’s surface and near surface, which has accelerated in the past two centuries. The large-scale intentional excavation, transportation, and deposition of mixtures of rock and soil to form anthropogenic deposits and landforms represent a new geological process that could be used as a diagnostic signature of the Anthropocene. Keywords Anthropocene Á Stratigraphy Á Anthropogenic deposits Stratigraphic Issues Related to Anthropogenic Deposits The ground surface and deposits immediately beneath are an open system prone to modification through urban redevelopment, agricultural ploughing, and soil for- mation. This system may be the product of several phases of ongoing evolution and therefore dating this interval is problematic. The history of excavation in C. N. Waters (&) Á S. J. Price Á J. R. Ford Á A.

In the areas studied, that is between Salar de Pedernales (26°S) and El Tránsito (29°S), the depositional system is interpreted as a h:>moclinal ramp, on which fourerwironmentaJ subdivisions can be distinguished: shallow siliciclastic ramp, mixed siliciclastic-carbonate ramp, midd/e carbona:e ramp, and deep carbonate rampo In an offshore direction, they reflect a general decrease in terrigenous sediment input, anergy level, grain-size, and oxygen supply, and a relative increase in carbonate production. More than 200 bulk collections of benthic macroinvertebrates, dominated by bivalves and brachiopods, were grouped into 27 associations (1-27) and 3 assemblages (E,F,G) by means of a O-mode cluster-analysis. Most associations are restricted to a single environmental subdivision and therefore proved to be useful indicators of generalenvironmental conditions and bathymetry. This is also true for guild-assemblages. Higher numbers of dominant guilds and a relatively broad guild-spectrum within highly-diverse associations are found in the more onshore settings. Due to a stable and consolidated substraie, on!he middle carbonate ramp only pedunculate brachiopods and epifaunal bivalves could gain high abundances in associations of moderate diversity. An even higher dominance of only a few guilds is found on the oxygen-controlled deep rampoTypical representatives of low-diversity associations were deposit-feeding nuculid bivalves in the upper dysaerobi:: biofacies zone and small, flat-'valved pectinacean bivalves in the lower dysaerobic zone.
