In the course of working through the large collection of Coal-measure fossils in the Manchester Museum I have recently discovered a number of interesting, and hitherto unrecorded, forms from the well-known ‘Marine Band’ in the Middle Coal-measures of Ashton-under-Lyne. The most interesting of these additions is undoubtedly Archæocidaris, a genus which is not at all common in the Coal-measures of this country, though fairly abundant in North America. Hitherto it has only been recorded from the North and South Staffordshire Coal-fields; its discovery, therefore, at Ashton constitutes the third record for the British Isles.
