Six of these species have not previously been recorded from the British Isles and one species, Micraster (Gibbaster) norfolkensis, is new. New plating diagrams are provided for these species. In addition a cassiduloid, Arichiacia sp., and a new holasteroid, Pseudananchys speetonensis sp, nov., are described.
