A polychaete from the Middle Devonian Arkona Shale at Hungry Hollow, Arkona, Ontario is preserved in three dimensions in pyrite. The prostomium bears a single median antenna, a pair of lateral antennae and a pair of ventral palps. It is assumed to be fused to a reduced peristomium. The anteriormost three pairs of trunk appendages are modified as tentacular cirri, the third long and biramous. Th...

Recently specimens of the polychaete Marphysa sanguinea (Montagu, 1813) (Annelida: Eunicida: Eunicidae) were reported as an introduction to the Eastern Scheldt in southwestern Netherlands. In order to confirm the species identity, material was examined with SEM and compared with material from Devon near the type locality in Cornwall, UK. These studies confirmed that this was a new record of M. ...

•A new subfamily of Poiynoidae, Eulagiscinae, is established for Eulagisca Mclntosh, to include the type species E. corrientis, E. gigantea Monro, E. puschkini Averincev, and two new species, E. uschakovi and E. macnabi, all from the Antarctic and Subantarctic regions, and the new genus Pareulagisca for P, panamensis (Hartman), new combination, from the central Pacific Panama region. Mclntosh (...

Background. Therapeutic properties of Teucrium species as antioxidant, antibacterial, analgesic, anticancer, diuretic, and tonic compounds have been proved earlier. Materials and Methods. In this study, the antinociceptive and anti-inflammatory effects of the aqueous extract of Teucrium persicum on chronic pain, sciatic nerve ligation as a model of neuropathic pain, and inflammatory models were...

Palaeoannelida Weigert and Bleidorn, 2016 is an old clade branching off at the base of Annelida radiation. It includes two morphologically ecological divergent groups sedentary burrowers tube-dwellers: Magelonidae Cunningham Ramage, 1888, Oweniidae Rioja, 1917. Magelonids are characterised by a flattened, shovel-shaped prostomium pair ventral papillated palps. Oweniids have simplified bodies la...
