A B S T R A C TThe drawings, detailed pictures, precise descriptions and measurements that characterize otoliths must be made available for studies in various areas, including taxonomy, phylogeny, ecology, fisheries, paleontology, diversity, predator-prey relationships and modeling. The Collection of Teleostei Fish Otoliths of Southeastern-Southern Brazil (COSS-Brasil) of IOUSP contains 45,000 pairs of otoliths from 210 species. This publication is the first in a series that will constitute an atlas of Teleostei otoliths for southeastern-southern Brazil and presents the results of the morphologic and morphometric analyses of 11 Gadiformes and 36 Perciformes species by means of the most commonly used features, measurements and indices. Three otoliths of each species were illustrated and photographed whenever possible. The frequency of occurrence was calculated for each characteristic by total length classes (TL), and the ontogenetic differences were analyzed (multiple χ2 test; significance 0.05). Morphometric analyses were conducted for each characteristic per total length (TL) class and for the whole sample, and the ontogenetic differences were analyzed. R E S U M OA disponibilidade de desenhos, fotos detalhadas, descrições precisas e medidas que caracterizem os otólitos são ferramentas imprescindíveis para diversas áreas: taxonomia, filogenia, ecologia, pesca, paleontologia, diversidade, relações presa/predador e modelagem. Da Coleção de Otólitos de Peixes Teleósteos da Região Sudeste-Sul do Brasil (COSS-Brasil), IOUSP, constam quarenta e cinco mil pares relativos a 210 espécies. Esta publicação é a primeira de uma série que constituirá um atlas de otólitos para Teleostei da região sudeste-sul brasileira e apresenta os resultados de análises morfológicas e morfométricas de 11 espécies de Gadiformes e 36 de Perciformes das medidas e índices usualmente realizados. Foram desenhados e fotografados três otólitos de cada espécie sempre que possível. A frequência de ocorrência foi calculada por classes de comprimento total (TL) e para toda a amostra, e diferenças ontogenéticas foram analisadas.

This publication is the second in a series that will together constitute an Atlas of Teleostei Otoliths for the Southeastern-Southern Brazilian area. Here we present results of morphologic and morphometric analyses of 12 Clupeiform species (3 Clupeidae, 7 Engraulidae and 2 Pristigasteridae) by means of the most commonly used features, measurements and indices. Three otoliths of each species have been illustrated and photographed whenever possible. The frequency of occurrence has been calculated for each characteristic by total length class (TL), and the ontogenetic differences have been analyzed (multiple χ² test; significance 0.05).

Nela são apresentados os resultados de análises morfológicas e morfomé-tricas de 12 espécies de Clupeiformes (3 Clupeidae, 7 Engraulidae e 2 Pristigasteridae) através de feições, medidas e índices usualmente utilizados. Três otólitos de cada espécie foram desenhados e fotografados, sempre que possível. A frequência de ocorrência foi calculada para cada característica por classes de comprimento total dos peixes (CT) e as diferenças ontogenéticas foram analisadas (Teste χ² múltiplo; significância 0,05).

This publication is part of a series prepared with the purpose to constitute an Atlas of Teleostei Otoliths for the Southeastern-Southern Brazilian area. Here we present the results of 15 morphological features and six shape indices for 33 Perciformes species of 20 families. Whenever available in out collection, three otoliths of each species were illustrated and photographed. The frequency of occurrence of each feature was calculated inside and among total length classes being the differences analyzed through multiple χ2 tests (significance level 0.05). Based on otoliths measurements, six shape indices values were obtained being the minimum, maximum, mean and standard deviations values presented.

In addition to the series of documents that we have been publishing on the "Atlas of Teleostei Otoliths for the Southeastern-Southern Brazilian region", in this volume we present the results of species of the orders Atheriniformes (1 species), Beloniformes (5), Beryciformes (2), Zeiformes (2), Syngnathiformes (2), Scorpaeniformes (9) and Tetraodontiformes (6). Features, measurements and indices were analyzed according to methodology used in anterior series. Three otoliths of each species have been illustrated and photographed whenever possible. The frequency of occurrence of each characteristic was calculated by total length classes (TL), and differences within and among classes have been analyzed applying the multiple χ2 test (significance 0.05).

To complement the series of manuscripts published as "Atlas of Teleostei Otoliths of the Southeastern-Southern Brazil", in this volume we present results for species of Siluriformes (two species) and Pleuronectiformes (thirteen species) orders. Considering that the sagittae of Siluriformes are very small we analyzed the left lapillus. Due to the asymmetry of the Pleuronectiformes otoliths, were analysed both left and right structures, being the circumsulcal depression the most important feature to diagnose these species. AbstrActDescriptors: Sagittae, Lapilli, Morphology, Morphometry, Siluriformes, Pleuronectiformes.Em complemento à série de manuscritos publicados como "Atlas de Otólitos para os Teleósteos da região Sudeste-Sul do Brasil", neste volume apresentamos os resultados obtidos para espécies das ordens Siluriformes (duas espécies) e Pleuronectiformes (treze espécies). Tendo em vista que os sagittae dos Siluriformes são muito pequenos, foram analisados os lapilli esquerdos. Devido a assimetria dos Pleuronectiformes, foram analisados tanto sagittae esquerdos quanto direitos, sendo a depressão circumsulcal a feição mais importante para diagnosticar as espécies desta ordem.

This publication is part of a series that will constitute an Atlas of Teleostei Otoliths for the Southeastern-Southern Brazilian area. It presents the results of the morphological and morphometric analyses of 31 Perciformes (two species of Centropomidae; two of Acropomatidae; two of Serranidae; two of Priacanthidae; two of Malacanthidae; one of Pomatomidae; six of Carangidae; three of Lutjanidae; five of Gerreidae and six of Haemulidae). Whenever available in the collection, otoliths from three distinct specimen sizes were illustrated and photographed in order to show their variation during development. For each characteristic the frequency of occurrence was calculated within each length class (TL) and among length classes (during development) and differences were analyzed by a multiple χ² test (significance 0.05).

This publication is part of a series that will constitute an Atlas of Teleostei Otoliths of the Southeastern-Southern Brazilian region. In this article, we present the results of sagittae's morphologic and morphometric analyses from fishes remaining to the orders: Albuliformes (one species), Anguiliformes (four), Osmeriformes (one), Stomiiformes (one), Aulopiformes (five), Myctophiformes (nine), Ophidiiformes (three), Polimixiiformes (one), Batrachoidiformes (one) and Lophiformes (three). Features, measurements and indices were analyzed according to methodology used in anterior series. Whenever possible three otoliths of each species have been illustrated and photographed. The frequency of occurrence of each characteristic was calculated by total length classes (TL) and differences within and among them have been analyzed applying multiple χ² test (significance 0.05).

Foram analisadas feições, medidas e índices usualmente empregados conforme metodologia apresentada nas séries anteriores. Três otólitos de cada espécie foram desenhados e fotografados, sempre que possível. A frequência de ocorrên-cia de cada característica por classe de comprimento total foi calculada (CT) e as diferenças dentro de cada classe e entre elas foram analisadas aplicando o Teste χ² múltiplo (significância 0,05).

Urophycis Gill 1864 is a genus of demersal fish composed by eight valid species with anti-tropical distributions in the western Atlantic. Only two species occur in the South Atlantic: U. brasiliensis (Kaup 1858) and U. mystacea Miranda Ribeiro 1903. These species have similar ranges from southeastern Brazil to northern Argentina, but U. brasiliensis occurs in more shallow waters than U. mystacea. Both species are important fishery resources in southern Brazil and Uruguay. Herein, we redescribe U. brasiliensis based on comparison of types and additional specimens, including the description of the Sagitta otolith, formerly place U. latus Miranda Ribeiro 1903 as a junior synonym of U. brasiliensis, and provide an updated map of distribution.
