| Abstract: | From an examination of the original material of G. O. Sars and new material from Björnehodebukta, Oslofjord, Psammis longisetosa Sars is redescribed, noting in particular the presence of 2 inner setae on P2 endopod 2 and 1 inner seta on P4 exopod 1. A new species is described from the Celtic Sea, Paradanielssenia biclavata , characterized by the presence of club-shaped appendages on the mouthparts and differing from P. kunzi Soyer in mouthpart structure and limb setation. Specimens from the Gulf of Mexico have been assigned to a new subspecies, Thompsonula hyaenae elongata , after careful comparison with specimens of the nominate T. hyaenae (I. C. Thompson) from Europe and South Carolina. |
