The present study analyses ostracods from sedimentary samples collected in the São Pedro-São Paulo Archipelago, a small set of remote rock islands located Northeastern to the Brazilian coast. Thirteen species were identified, and their zoogeographical distribution was studied. An emendation for Keijcyoidea praecipua (Bold, 1963) is proposed in this paper. The distribution of the species which occur in the archipelago varies significantly: Triebelina sertata Triebel, 1948, is a cosmopolitan species; Loxoconcha (Loxocorniculum) tricornata is assumed to occur from the Caribbean Sea to the tropical portion of the Brazilian coast and Western Africa. Keijcyoidea praecipua is recorded through the Pacific and Atlantic coasts of Central America and Northeastern Brazil. Xestoleberis toni? Wouters, 2003 and Triebelina cf. intermedia Witte, 1993 are known from the African coast. Neonesidea tenera? (Brady, 1886) emend. Maddocks, 1969 is found along the Indian and Pacific oceans. The species Pontocypris (Ekpontocypris) pirifera? (Müller, 1894) is also present in the western European coast and the Mediterranean Sea. Six species are probably new and have not been observed elsewhere: Aurila sp. 1, Paradoxostoma sp. 1, Paradoxostoma sp. 2, Xestoleberis sp. 1, Xestoleberis sp. 2 and Xestoleberis? sp. 3.

Three New Species

A consultation of the original descriptions of the genera of Scissurellidae led the author to conclude that the valid names for the genera of this family are: Scissurella d'Orbigny, 1823 (redescription by Sowerby, 1824), Anatoma Woodward, 1859, Inoisura Hedley, 1904, Scissurona Iredale, 1924, Sinezona Finlay, 1927. Scissurella and Anatoma are cosmopolites, the first generally living in shallow waters, associated to sea-weeds, while the second is found in deep waters. The three last genera are restricted to Australasia. Three new species are described from the Brazilian coast: Soissu rella alexandrei, Scissurella eleotilis and Scissurella morretesi. The internal anatomy of S. alexandrei is described. These three new species have been found in littoral shallow waters, the two first on the northeast Brazilian coast, the third on the coast of the State of São Paulo. The fourth known species of Scissurellidae from Brazil, Anatoma aedonia (Watson, 1886), was dredged by H.M.S, "Challenger", in 1873, off Pernambuco, 350 fm (640 m).

In February-March 1963, during the Equalant Operation for the ICITA program, 476 drift-bottles were released at the equatorial waters off the northern Brazilian coast (01ºS to 09ºN and 043ºW to 053ºW). Thirty-five, bottles were recovered (7,4%). Those were classed in five groups according to their different velocity ranges and areas of recovery (Trinidad Island; Lesser Antilles; Caribbean and Florida area; north Brazil; northeastern Brazil). The recoveries of bottles released within 300 nm off the northern and northeastern coast of Brazil confirmed a strong current along the north and northeast coast in northwestern direction (South Equatorial Current and branches). In late February-early March the bottles showed maximum velocities of this current (3,6 knots). The region off the northern coast of Brazil, between 05ºN and 09ºN up to 050ºW seems to have been under the influence of an eastward component of the surface current in this same period, while at late March this influence appears to have been weaker. In the region from Trinidad Island to Yucatan Peninsula the current seems to be stronger on the northeastern side of the Caribbean Sea.

Specimens of Bentharca asperula (Dall, 1881) were obtained from deep waters of the coasts of the Rio de Janeiro and São Paulo States, and their shells described, illustrated and compared with descriptions and illustrations obtained from the literature. This species has a small strongly inequilateral shell, trapezoidal in outline and expanded ventro-posteriorly; their umbos are placed at about 1/3 of the anterior length of their straight hinge line. The external sculpture consists of irregular spaced concentric ridges, intercepted by fine radiating striae; the periostracum is hairy, forming a cover as a thatch. Hinge teeth are small, disposed in two series interrupted by the ligament. With this finding of living specimens from the Bacia de Campos, the distribution of B. asperula can now be extended in the Brazilian coast, confirming its wide spread in the Atlantic Ocean.

ResumoO presente artigo aborda a trajetória científica da arqueóloga Niède Guidon, brasileira nascida no interior de São Paulo e Doutora em Pré-História pela Université Paris I Pantheon-Sorbonne. Chegou na cidade de São Raimundo Nonato (Piauí) em 1970 em busca de vestígios arqueológicos provenientes daquela região. Ao deparar-se com resultados de análises enviadas à laboratórios franceses, no qual datavam através da técnica com Carbono-14 artefatos e vestígios arqueológicos com mais de 18 mil anos BP[1], Niède ampliou suas pesquisas e reuniu esforços pela preservação do local que hoje é conhecido como Parque Nacional da Serra da Capivara, patrimônio cultural da humanidade pela Unesco. Em 1986, publicou suas descobertas na prestigiada revista científica britânica Nature, dando destaque internacional para os sítios arqueológicos do nordeste brasileiro. A partir daí Guidon continuou seu trabalho e suas descobertas arqueológicas constataram artefatos com datações de 100 mil anos BP, desenvolvendo novas teorias para a origem do homem americano, refutando assim a teoria mais aceita do Estreito de Bering. Isto causou a indignação de diversos arqueólogos internacionais e nacionais que questionavam a veracidade de suas pesquisas. Mesmo com todas essas polêmicas, Niède Guidon e demais pesquisadores seguem com seus estudos nos mais de 1300 sítios arqueológicos da região do Piauí, sugerindo que mais resultados ainda estão por vir.Palavras-chave: Niède Guidon; Arqueologia; Pré-história brasileira.AbstractThis article deals with the scientific accomplishments of the archaeologist Niède Guidon, a Brazilian born in the interior of São Paulo who earned a Ph.D. in Prehistory from the Université Paris I Pantheon-Sorbonne. He arrived in the city of São Raimundo Nonato (Piauí) in 1970 in search of archaeological remains from that region. When he first received the results from French laboratories of Carbon-14 analyses, a method capable of dating artifacts that are at least eighteen thousand years old, Niède expanded his research and joined efforts to preserve the location now known such as Serra da Capivara National Park, a UNESCO World Heritage Center. In 1986, he published his findings in the prestigious British scientific journal Nature, gaining international prominence for the archeological sites of northeastern Brazil. From there Guidon continued his work and his archaeological discoveries, finding artifacts dating to 100,000 years before the present (BP), developed new theories for the origin of American humankind, thus refuting the more accepted theory of the humankind’s migration across the land bridge between Asia and North America. This caused indignation among several international and national archaeologists who questioned the veracity of his research. Even with controversies, Niède Guidon and other researchers have continued their studies in more than 1300 archaeological sites in the Piauí region, which suggests that more findings can be expected.Keywords: Niède Guidon; Archeology, Brazilian Prehistory.[1] Before the Present – Antes do Presente – escala utilizada pelas disciplinas científicas na datação de eventos do passado em relação à data presente.

The Status

Porcellana paivacarvalhoi Rodrigues da Costa, 1968, described from southeastern Brazil (São Sebastião, São Paulo), is morphologically similar to the eastern Atlantic P. platycheles (Pennant, 1777), and also to the west African P. africana Chace, 1956. The synonymy between P. paivacarvalhoi and P. platycheles was proposed by previous authors without examination of any specimens of P. platycheles, nor did they considered the morphological similarities between P. paivacarvalhoi and P. africana. This synonymy has been implicitly accepted without further analysis. The recent discovery of one male and two females syntypes of P. paivacarvalhoi has prompted new investigations into the status of P. paivacarvalhoi as a junior synonym either of P. platycheles or P. africana. Porcellana paivacarvalhoi is redescribed and illustrated based upon its lectotype herein designated. It is confirmed to be a junior synonym of P. platycheles; all evidence suggests that P. africana is a distinct, separate species. All previous records of P. platycheles from the Brazilian coast are reviewed. Its presence in southeastern Brazil in the late 1960’s most probably represents an historical case of human-mediated introduction by shipping activities. Porcellana platycheles did not manage to establish itself in São Sebastião, nor has it been recorded subsequently elsewhere in Brazil.

The discussion in this article is associated with the experience of field researches in four Brazilian cities, Brasília, São Paulo, Rio de Janeiro and Manaus, between 2011 and 2015, having as guideline the negotiations for belongingness performed by contemporary immigrant communities in Brazil. From questions made by Stuart Hall in “Thinking the diaspora”, mainly the question of the Caribbean diaspora, we discuss the new belongingness negotiation and the imaginary desire to the return to the land left. Exploring this tension is the objective of this article, bringing the debate to the new immigrant communities in Brazil.

The regional dialects or regiolects of the Rufous-collared Sparrow Zonotrichia capensis were compared between Campinas (47º06'W-22º90'S) and Botucatu (48º44'W-22º88'S), São Paulo State, Southeastern Brazil. Songs of 88 individuals from thirteen localities were recorded. Sonograms showed that two areas presented more homogeneous songs, forming two regiolects. In 11 localities most individuals shared the same song type. At the other two localities, they sang up to 5 different song types. This occurs at the boundaries of the regiolects, and was also where individuals singing more than one song type were found. Similarities between song types were not related to geographic distance between the respective singers. A comparative analysis showed similarities in these regiolects with song of populations from Northeastern Brazil.
