| Microscopical investigations of the gut contents of six individuals of Dermochelys coriacea from southern England and the North Sea revealed the presence in all of these of numerous nematocysts, mainly scyphozoan. Only six species of Scyphozoa occur in British shallow waters and in the North Sea, viz., Pelagia noctiluca (Forskål), Chrysaora hysoscella (L.), Aurelia aurita (L.), Cyanea capillata (L.), C. lamarckii (L.) and Rhizostoma octopus (L.). For the purpose of comparison and identification an inventory was made of the cnidom of these six species (based on preserved material). Nematocysts of one or more of these species appeared to be present in each of the turtles, all six species being represented. One of the turtles in addition appeared to have... |

| 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... |

| The behavioural patterns of 26 species of Antho- and Leptomedusae (with or without medusa stage) were investigated by video recordings. The analysed activities were: answers to mechanical stimuli, prey capture and ingestion, digestion, egestion, and swimming. The quantity of behavioural patterns identified in the small number of hydrozoan diversity studied so far is sufficient to demonstrate that these supposedly "simple" animals have evolved a complex array of responses to both external and internal stimuli. |
