| Jäderholm's type of Schizotricha antarctica, collected by the Swedish Antarctic Expedition 1901-1903, is redescribed from a syntype in the collections of the Swedish National Museum, Stockholm. The type lot of that species proved to be composite, the material best resembling Jäderholm's (1904, 1905) descriptions and figures has been designated as the syntype. There are two more species in the type lot, that have also been described, but are too poorly represented to be either recognized as one of the described species of Oswaldella or to merit a new specific name; they have been indicated as Oswaldella spec. 1 and spec. 2. Resumen: Se ha revisado y redescrito el material tipo de Schizotricha antarctica Jäderholm, 1904, recogido durante la Swedish Antarctic... |

| The newly liberated, immature medusae of H. scandens, Hebella furax, H. muscensis, and the liberable eumedusoid of H. dyssymetra are described. The taxonomy of the medusa-producing Hebellinae is revised in the light of life cycle features. Due to inconsistencies between skeletal and medusan features, Hebellopsis is merged into Hebella. The new genus Anthohebella is proposed for the hebellids with swimming gonophores. All the nominal species referred to Hebella and Hebellopsis are discussed; out of the 45 nominal species referred at least once to Hebella and Hebellopsis, 15 are retained as valid: 11 are referred to Hebella and four to Anthohebella gen. nov.; 12 nominal species are considered conspecific with currently recognized species referred to the... |

| Hydroid distribution patterns along a horizontal ecocline in the Rio Formoso/Rio Ariquindá/Rio Porto Alegre system, a small and seasonally poikilohaline estuary on the tropical northeast coast of Brazil, were investigated. Collecting was undertaken during the dry season, in November 1993, by diving (with and without SCUBA). Nine stations were sampled on a transect extending from a reef outside the river mouth to a mangrove system at the upper end of the estuary. Four major regions were distinguished along the ecocline based on numerical analyses of hydroid species/station location data: (1) nearshore reef — a sandstone ledge outside the entrance of the estuary; (2) river mouth — a sandy and shelly flood-tidal delta area inside the entrance of the Rio... |

| Este grupo en Cuba permanece aún muy poco estudiado, pues aunque para el Golfo de México y el Mar Caribe se conocen 13 familias y 19 especies de cubozoos y escifozoos (Cairns, et al., 2002 y Segura-Puertas et al., 2009), hasta el momento solo se conocen cuatro familias y nueve especies de estos organismos para el Archipiélago cubano (Lalana et al., 2001 y Varela, 2006). |

| RESUMO O registro fóssil do Devoniano do estado de Goiás (Sub-bacia Alto Garças, Bacia do Paraná) é ocorrente nos arredores de diversas cidades como Amorinópolis, Iporá, Caiapônia, Rio Verde e Doverlândia. Contudo, os fósseis encontrados em Goiás são, em sua maioria, representados por braquiópodes, comumente pertencentes aos gêneros Derbyina, Australocoelia, Australospirifer, Schuchertella, Orbiculoidea e Lingula. Embora também haja ocorrências, em menor número, de outros grupos como trilobitas, moluscos, tentaculitoideos, anelídeos, equinodermas, lycopsidas e cnidários, além dos microfósseis de quitinozoários, representados pelos gêneros Ramochitina, Ancyrochitina, Sphaerochitina, Angochitina, Conochitina, Lagenochitina e Cyathochitina. No entanto, os... |

| Associations between jellyfish and other organisms are frequently reported. Neverhteless, few of those records include crabs inhabiting medusae. Lychnorhiza lucerna Haeckel, 1888 were sampled (n = 1988) on the coast of the State of Paraná (25º20'-25º55'S, 48º10'-48º35'W), southern Brazil, from December 1997 to December 2004. Eight percent (166 individuals) of the medusae had one spider crab Libinia ferreirae Brito Capello, 1871 living within its subgenital porticus or on the oral arms. Megalopal stages of the same crab were also found on three jellyfish. All crabs associated with L. lucerna were young and smaller (< 3 cm) than solitary crabs caught on the bottom. Thus, L. ferreirae probably colonizes the jellyfish as a late larva and uses it as a... |

| The holotype of Malvinoconularia cahuanotensis (Brania and Vanek) (Devonian, Bolivia), the type species of the monospecific genus Malvinoconularia Babcock et al., is redescribed and refigured. M. cahuanotensis exhibits several gross morphological features that together are uniquely shared with Reticulaconularia baini (Babcock and Feldmann). In both taxa, the transverse ribs are nodose, the interspaces bear longitudinal ridges (bars or crests) that are collinear (line up) across the transverse ribs, and the longitudinal centerline (midline) of the faces is marked by a subdued ridge. Additionally, the two species may also be similar in the anatomy and external ornament of the corner sulcus. The slightly undulose geometry of the transverse ribs of M.... |

| Renewed interest in conulariids has resulted in clarification of problems in the paleobiology of this group. Discoveries of skeletal structures and specimens preserved in situ, coupled with cladistic analyses, have led to a revival of Kiderlen's (1937) hypothesis that conulariids were polypoid scyphozoans or a sister taxon of this class. Until 1979, research on conulariids centered on the description of new species and on the erection of subgroups using phenetic approaches. Few papers addressed the paleobiology and phylogenetic affinities of conulariids, and none employed cladistics. In contrast, the 1980's saw the publication of major papers on the paleoecology of conulariids, and during this decade the hypothesis that conulariids were benthic organisms... |

| Seabather's eruption is a papulo-pruritic dermatitis caused by the nematocysts of the larvae of the jellyfish Linuche unguiculata retained in the clothing fibers. Previously reported in Brazil, this work describes fourteen cases that occurred in the State of Santa Catarina, in southern Brazil. The new cases observed over a short period of time (the first half of January, 2012), at the height of the summer season, should alert health teams to possible epidemics on the coast of the state of Santa Catarina. |
