Besnard. Assim este trabalho representa, de certo modo, uma contribuição aos resultados da Expedição do navio 'Baependi', realizada em 1950, à Ilha da Trindade. <![CDATA[<b>Resultados científicos do cruzeiro do "Baependi" e do "Vega" à Ilha da Trindade</b>: <b>contribuição para o conhecimento da plataforma insular da Ilha da Trindade</b>]]> http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-42391951000200002&lng=pt&nrm=iso&tlng=pt The oceanographic work realized during 10 days in the surroundings of the eruptive island of Trindade, 20º30'36" lat. S - 29º19'26" long. W, had as principal aim the determination of the insular plateau, whose knowledge was very insufficient. Thus were established some oceanographic stations and sounding lines were realized by means of an echobathymeter whose responses were initially verified with mechanical soundings obtaneid by means of a Thomson sounder. The insular plateau is very narrow and exhibits a sudden fall between the 100 and 120 m. depth line at 740 m. - 2950 m. from the coast. Its greatest depth is of 108,30 m. and its mean inclination is of 8,12%. The plateau of the island of Trindade is separated from that of the neighbouring group of Martim Yaz by great depths. The bottoms are rocky near the coast, the blocks having been produced by the rupture of the magmatic mass of the island. Further away from the coast, the size of the rocks gradually diminishes up to the fine sand thickness. In the litoral zone there are abundant tufts of living Lithothamnion with a rich associated flora and fauna, which partly covers the rocks themselves. Further off at sea, the spheres of the dead alga with its commensals are cimented together by sedimentation. The spheres are further broken up and become an integrating part of the sand. The results of the physical and chemical analyses of the sand bottoms are shown in tables 2 and 3. The coast is either of abrupt rocky walls falling down to sea level, or of shores, made of pebbles or of sand. Anyhow, there are frequently Lithothamnion terraces slightly inclinated towards the bottom (chemical analysis table 1). <![CDATA[<b>Contribuciones a la ictiologia</b>: <b>V - VI sobre algunas especies de<i> Gobiidae</i> de la colección del Laboratorio Aragó (Banyuls-sur-mer, Francia) y descripción de un nuevo genero<i> (Austrogobius)</i> sudamericano</b>]]> http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-42391951000200003&lng=pt&nrm=iso&tlng=pt En el número V de "Contribuciones a la Ictiologia" se dán normas para el estudio sistemático de los organos ciatiformes, que proporcionaron a los Gobiidae de Europa un medio seguro de ordenación genérica y distinción específica. Se añade el estudio de la colección del Laboratorio Aragó, de Banyuls-sur-mer, Francia. En el número VI de "Contribuciones a la Ictiología" se aloja el Gobiosoma parri Ginsburg en el nuevo gênero Austrogobius De Buen, y se dán las características que lo distinguen, especialmente la distribución de tubos mucosos y geniporos.<hr/>No número V de "Contribuciones a la Ictiología", o autor faz referências a algumas espécies de peixes da família Gobiidae, da coleção do Laboratório Aragó (Banyuls-sur-mer), fornecendo normas para o estudo sistemático baseadas nos órgãos ciatiformes, ou terminações sensoriais. Dessa maneira efetuou o Autor a determinação genérica e específica de alguns Gobideos da Europa. No número VI de "Contribuciones a la Ictiología" faz-se a descrição de um novo gênero (Austrogobius) de Gobídeo sul-americano, no qual é colocado o Gobiosoma parri Ginsburg, fornecendo-se as características que o distinguem, especialmente a distribuição de tubos mucosos e geniporos. <![CDATA[<b>Resultados científicos do cruzeiro do "Baependi" e do "Vega" à Ilha da Trindade</b>: <b>o gênero<i> Firoloida, Prosobranchia Heteropoda</i></b>]]> http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-42391951000200004&lng=pt&nrm=iso&tlng=pt From the Jaseur Bank, off the Brazilian coast at 20º 30' S - 35º 50' W, were collected a few specimens of one of the less known species of the Heteropoda: Firoloida lesueuri (d'Orbigny). A detailed anatomical description follows aiming at the elucidation of some obscure points in the litterature on the subject and at showing the identity of most of the previously described "species" of the genus Firoloida. Special care was taken with the study of the nervous system of which most of the descriptions found were discordant. The author arrived at the conclusion that the pleural ganglia are either missing of fused to the cerebral ganglia, that the supraintestinal ganglion (left parietal ganglion) is present in the posterior region and is close to the subintestinal or right parietal ganglion, being both located near the rear end of the body. The innervations are described and discussed as well as the fusion of extensive tracts of the connectives. The present material is shown to be identical to F. kowalewskyi, well described by Vayssière and Tesch; F. desmaresti (Lesueur 1817) is shown to be undistinguishable from F. blainvilleana and F. gracilis. F. aculeata and F. gaimardi are here considered as "nomina nuda". F. liguriae Issel 1907 is admitted as separate species in spite of its insufficient description and, finally, F. vigilans (Troschel 1855), unsatisfactorily described from only one specimen is perhaps a valid species. A table is presented to show the slight differences between the 4 species which are undoubtedly very similar. F. desmaresti is found only in the Atlantic north of the line and a few points south and close to it as well as in dependent seas, while F. lesueuri is common to the south Atlantic, south Indie and south Pacific oceans, extending north only up to the Azores Islands. F. liguriae is from the south western Atlantic. ?F. vigilans would be an endemic species from Messina (Mediterranean). <![CDATA[<b>Resultados científicos do cruzeiro do Baependi e do Vega à Ilha da Trindade</b>: <b>oceanografia física - contribuição para o conhecimento das características físicas e químicas das águas</b>]]> http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-42391951000200005&lng=pt&nrm=iso&tlng=pt In May 1950 a trip was undertaken by the ships "Baependi" and "Vega" to the Trindade Island - 20º30'S and 29º20'W - Approximately 1200 km off the coast of Espirito Santo State. This scientific expedition was realized by the iniciative of the Minister J. A. Lins de Barros. In this expedition the supervisor of the oceanographic works was Prof. W. Besnard, the director of the São Paulo Oceanographic Institute. He brougth home 42 samples of water for study, collected upon the insular terrace of the island, referring to the 15 established stations - see table I - with depths varying between 0 m and 115 m. The physical and chemical properties of them are to be seen on table II. The results obtained were compared with those of the German Expedition to the South Atlantic, 1925/27 ("Meteor"), observed at the stations 157-158-159-163 of profile VI and 168-169-170 of profile VII. The mean results obtaneid by the boats "Baependi" and "Vega" are represented on table IV. We constructed vertical sections - I to VI - of each group of Stations, showing the slope of the insular shelves and, in a general manner, the distribution of salinity. We made also longitudinal section - E, M, I - involving the island and corresponding, respectively, to the groups of stations, the farthest, nearest and intermediary ones. As the number of samples received is reduced and consequently the data obtained are few, no conclusions could be deduced. We made only a commentary supposing that the predominating waters surrounding the island are the same as those coming from the mentioned stations on Profile VI, marked by the "Meteor". No indication authorizes the supposition that waters of the Brazil Current or those of Profile VII of the "Meteor" reach the Trindade Island. On the contrary, its waters must be warm and salted to which Albert Defant (Die Troposphaere, Wiss. Erg. D. Atl. Exp. "Meteor" Band VI, 1 Tel Lief. 3, Berlin, 1936) has referred, as the island is located very near to the limits of the perspective diagram of warm water circulation pointed out.

O autor examinou 5 exemplares (2e 3 ) provenientes de Ubatuba e 8 exemplares (4 e 4 ) oriundos da Ilha Vitória, situada no litoral norte do Estado de São Paulo, nas proximidades da Ilha de São Sebastião. A maioria dos especialistas que se ocupam do grupo parece não ter tomado em consideração o trabalho de Gill (1898), que subidividiu o gênero Scyllarus em dois: Scyllarus e Scyllarides, colocando, quase sempre, no primeiro gênero, espécies que devem figurar no segundo. Quase a totalidade dos indivíduos da família Scyllaridae que frequenta a costa brasileira, faz parte do gênero Scyllarides. Estabelecendo confronto entre as medidas dos exemplares do litoral bandeirante e os obtidos por Verrill e Rathbun, o autor passa em rápida revista os seus hábitos; referindo-se ao valor econômico por eles representado.<hr/>This paper mentions the presence of Scyllarides brasiliensis Rathbun, in the littoral zone of the State of S. Paulo. The author examined 5 specimens (2 and 3 ) from Ubatuba and 8 (4 and 4 ) from the Island of Vitória, along the northern coast of the State, in the surroudings of the island of S. Sebastião. Many of the specialists that studied the group overlooked the work of Gill (1898) that splitted the genus Scyllarus in Scyllarus and Scyllarides and thus several species that ougth to be placed in the latter mentioned genus are still described as belonging to Scyllarus. Most of the species that inhabit the brazilian coast must be referred to Scyllarides. The author compares the measurements of the present specimens with those studied by Verrill and Kathbun, and rapidly refers the species' habits and its economic value. <![CDATA[<b>Notas sobre alguns copépodos parasitos de peixes marítimos da costa do estado de São Paulo</b>]]> http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-42391951000200008&lng=pt&nrm=iso&tlng=pt A presente nota trata de alguns copépodos, parasitos de peixes marítimos, e baseia-se em uma coleção de ecto-parasitos pertencentes às Subordens Cyclopoida, Caligoida e Lernaeopodoida que se encontra no Instituto Paulista de Oceanografia e que foi acumulada entre os anos de 1940 e 1949. Uma parte dos espécimes aqui tratados foi obtida por doação; outra teve por origem as periódicas viagens de estudo efetuadas pelos funcionários do Instituto, ao longo do litoral do Estado de S. Paulo; finalmente, uma pequena parte devida à aquisição de exemplares parasitados, nas feiras e mercados de Santos e S. Paulo. Dessa maneira, conseguiu o autor manipular 117 espécimes pertencentes a 8 famílias, 11 gêneros e 13 espécies diferentes, uma das quais, do gênero Caligus, não pôde ser determinada, por falta de bibliografia. O material foi retirado de 22 espécimes marinhos, entre os quais figuraram apenas 5 fortemente parasitados, contendo 10, 14, 16, 18 e 37 hóspedes. Nenhum dos hóspedes, porém, apresentou qualquer indício de depauperamento orgânico evidente.<hr/>The present note represents the inventary of the parasitic copepods found on marine fishes between 1940-1949 and which are kept in the "Instituto Paulista de Oceanografia" (São Paulo Oceanographic Institute). They all belong to the Suborders Cyclopoida, Caligoida and Lernaeopodoida and were partly received as donations and partly collected by the staff of the Institute, during its periodic trips to the coast of the State of São Paulo (Brazil); finally, a small fraction was obtained from parasitized fishes purchased on the markets of Santos an São Paulo. The author, thus, gathered 117 specimens, distributed by 8 families, 11 genera and 13 different species, one of which belongs to the genus Caligus and could not be specifically determined due to the lack of bibliography. The Copepods were obtained from 22 fishes, among which only 5 were abundantly infected and exhibited respectively 10, 14, 16, 18, and 37 parasites. None of the hosts showed any sign of evident organic weakness. <![CDATA[<b>Livros e revistas</b>]]> http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-42391951000200009&lng=pt&nrm=iso&tlng=pt A presente nota trata de alguns copépodos, parasitos de peixes marítimos, e baseia-se em uma coleção de ecto-parasitos pertencentes às Subordens Cyclopoida, Caligoida e Lernaeopodoida que se encontra no Instituto Paulista de Oceanografia e que foi acumulada entre os anos de 1940 e 1949.
