Three new sponge species in the demosponge families Chalinidae Gray and Suberitidae Schmidt are described from the Calypso hydrothermal vent field in the Bay of Plenty, and one species from seep sites along the Hikurangi Margin, to the east of the North Island, New Zealand. The Calypso hydrothermal vent field is dominated by the chalinid sponge Haliclona (Soestella) battershilli sp. nov., a large, cream-coloured, finely branched species, and the less common H. (Halichoclona) sonnae sp. nov., an encrusting, translucent white, cushion-shaped species. The third species, the suberitid sponge Protosuberites novaezelandiae sp. nov., forms encrustations with digitate projections. Haliclona (Halichoclona) sonnae sp. nov. and Protosuberites novaezelandiae sp. nov. represent new subgenus and genus records, respectively, for New Zealand waters. The methanotrophic suberitid sponge, Pseudosuberites thurberi sp. nov., is found at many of the cold seep sites on the Hikurangi Margin where it forms extensive, encrusting to digitate mats. The description of these species provides a basis for the future study of the ecology of sponges that are apparently endemic to vent and seep habitats off New Zealand.

Early in 1963 much of the land occupied by the Roman building at Fishbourne was purchased by Mr. I. D. Margary, M.A., F.S.A., and was given to the Sussex Archaeological Trust. The Fishbourne Committee of the trust was set up to administer the future of the site. The third season's excavation, carried out at the desire of this committee, was again organized by the Chichester Civic Society.1 About fifty volunteers a day were employed from 24th July to 3rd September. Excavation concentrated upon three main areas; the orchard south of the east wing excavated in 1962, the west end of the north wing, and the west wing. In addition, trial trenches were dug at the north-east and north-west extremities of the building and in the area to the north of the north wing. The work of supervision was carried out by Miss F. Pierce, M.A., Mr. B. Morley, Mr. A. B. Norton, B.A., and Mr. J. P. Wild, B.A. Photography was organized by Mr. D. B. Baker and Mrs. F. A. Cunliffe took charge of the pottery and finds.

Two new species of alvinocaridid shrimps are described from a hydrothermal vent field off northeastern Taiwan at depths of 252–300 m. Alvinocaris chelys n. sp. is morphologically very similar to A. williamsi Shank & Martin, 2003 from the Mid-Atlantic Ridge, and A. alexander Ahyong, 2009 from the southern Kermadec Ridge. These three species can be differentiated by the shape of the postrostral ridge, telson, the second segment of the antennular peduncle and the armature of the meri and ischia of the third pereopod. The second new species, although rather similar to Alvinocaris niwa Webber, 2004 from the Kermadec-Arc, is assigned to a new genus Alvinocaridinides gen. nov., which appears to be intermediate between Shinkaicaris Komai & Segonzac, 2005 and other derived genera including Opaepele Williams & Dobbs, 1995, Chorocaris Martin & Hessler, 1990 and Rimicaris Williams & Rona, 1986. Alvinocaridinides formosa n. sp. differs from Alvinocaris niwa by completely lacking any armature on the ischia of the third to fifth pereopods and by bearing two movable spines at the posterolateral angle of the uropodal exopod. These records constitute the first discovery of the family Alvinocarididae in Taiwanese waters and represent the shallowest occurrence for alvinocaridid shrimps.

The formation of the future tense is often mentioned in discussions on the classification of the modern Indo-Aryan languages. An -s- type of future occurs in Gujarati, Lahnda, and Jaipuri, an -h- type of future exists side by side with participial formations in Marwari, Hindi (Braj), and Bundeli, and in Bhojpuri and Awadhi (in the third persons only), as well as in Kashmiri, where it has assumed the meaning of a past conditional. Despite this Marwari belongs to the -s- group, forms with -h- being found in those dialects of Marwari that regularly have voiceless -h- < -s-. The explanation of the Kashmiri forms is similar (ś > h and -ṣy- > -śś- > -h- in Kashmiri). Thus -s- forms in principle are found over a large part of the North-West and West of India. Attempts have been made to trace back the modern conditions to earlier stages, and S. Sen claims that the two types of future go back to different Indo-European originals: “From early times there were dialectal forms with the base-affix -ha-, which became quite dominant in Apabhraṃśa.” (This is incorrect.) “The origin seems to have been the I.E. stem affix *-so-, OIA. -sa-, occurring in the desiderative, the aorist, and as a root-determinative.” The accepted opinion is that the two types of future have the same origin, the OIA. future suffix -i-ṣya-, and that differentiation did not take place till the Middle Indo-Aryan period. As has been shown conclusively by Turner and by Bloch, the future suffix of Sanskrit could have in MIA. a special development into -h- instead of -ss- which is phonetically regular, because it was in a weak position, being a terminational element.

This article recounts the story of how the Circassians have been able to raise awareness of their deportation in the 1860s during the Caucasian Wars. After a brief methodology the authors provide an overview of the Circassian history. The second section analyses the period when the Circassian population came under Russian rule after the 1860s. The third part focuses on three broad approaches or strategies used by several Circassian groups to increase the awareness of the Circassian subjugation in the 1860s. The last two sections discuss some of the changes that have occurred as a direct result of the work undertaken by Circassian organisations. The authours argue that the Circassians have created lieux de mémoire, especially since the beginning of the 1990s, what does not always overlap with the dominant Russian perception of history in the North Caucasus. The analysis demonstrates how the Circassians have (re)discovered their story and the impact of this new information on their actions.

The article discusses the future of mobility in the light of energy resources. Fossil fuel will not be available for a long time - not to mention its growing environmental and political conflicts. In analysing the potential of biofuel it is argued that the high demands of modern mobility can hardly be fulfilled in the future. Furthermore, the change into using biofuel will probably lead to increasing conflicts between the fuel market and the food market, as well as to conflicts with regional agricultural networks in the third world. Petrol imperialism might be replaced by bio imperialism. Therefore, mobility on a solar base pursues a double strategy of raising efficiency on the one hand and strongly reducing mobility itself on the other.

En este artículo examinaremos algunas de las principales estrategias discursivas empleadas en dos artículos publicados por U. Eco en L’Espresso, una revista semanal muy conocida en Italia de carácter político, social, cultural y económico, en el marco de una página personal titulada “La Bustina di Minerva”, es decir, “El Sobrecito de Minerva”. El título es una referencia a la comunicación breve, a las observaciones de cualquier tipo, pero igualmente, de forma simultánea. Los sobrecitos reflexionan sobre el mundo contemporáneo, la sociedad italiana, los medios de comunicación de masas; tratan de la actualidad y la relacionan con la historia y la filosofía, con Internet y el futuro del Tercer Milenio, y nos proponen los pensamientos de U. Eco con más viveza que una conferencia o un tratado.La ironía, la sátira y la parodia son las bases argumentativas de muchos “Sobrecitos”. Generalmente, el humor transmite dos sentidos a la vez. Detrás de una serie de textos tan variados temáticamente aparece a menudo una misma estructura binaria, un cuerpo dual. Con frecuencia, un mismo artículo obedece a una doble orientación tematica, ya que suelen mezclar dos motivos que pertenecen a áreas diferentes, alternando simultáneamente dos sujetos. A esta doble orientación temática del “Sobrecito” corresponde la doble orientación semántica de la palabra irónica que, junto con la parodia es un discurso dialógico o bi-direccional en el que se mezclan dos voces.In this article some of the main discursive strategies used in two articles published by U. Eco are examined. These articles have been published in L'Espresso, a weekly review very widespread in Italy, of political, social, cultural and economic character, within the framework of a column titled “La Bustina di Minerva”, that is to say, “The little bag/envelope of Minerva”. This title refers to a brief communication, to observations of any type, but also, immediate. The “bustine” reflects on the contemporary world, the Italian society, the mass media; they deal with present time and relate it to history and philosophy, Internet and the future of the Third Millennium, and they propose us Eco’s thoughts with more vividness than a conference or an essay.Irony, satire and parody are the argumentative bases of many “bustine”. Generally, humour transmits two senses simultaneously. Behind a series of texts so thematically varied there is often a same binary structure, a dual body. Frequently, a same article obeys to a double thematic direction, since usually they mix two arguments that belong to different areas, alternating two subjects simultaneously. To this double thematic direction of the “bustina” corresponds the double semantic direction of the ironic word that, along with parody, is a dialogic or bidirectional speech in which two voices are mixed.

Riccia marginata Lindb. was described by S. O. Lindberg (1877) from the outskirts of the town of Sortavala near the north shore of Lake Ladoga, Republic of Karelia, Russia. The species has been forgotten in most recent liverwort accounts of Europe, including Russia. Lectotypification of R. marginata is provided. R. marginata shares most characters with R. beyrichiana Hampe ex Lehm. It differs from “typical” plants of R. beyrichiana in having smaller spores, with ± distinctly finely areolate to roughly papillose proximal surfaces and a narrower and shorter thallus, as well as in scarcity or absence of marginal hairs. It may represent continental populations of the suboceanic-submediterranean R. beyrichiana, known in Russia from the Leningrad Region and Karelia only. The variability of spore surfaces in R. beyrichiana is discussed and illustrated by SEM images. A comparison with the spores of R. bifurca Hoffm. is provided. The question how distinct R. marginata is from R. beyrichiana needs to be clarified by molecular studies in the future, when adequate material is available. R. marginata is for the time being, provisionally, included in R. beyrichiana.
