The specimen to which the following description applies was found by the Rev. G. Crewdson, F.G.S., of Kendal, at the base of the cliff at Huntcliff. The block in which it lay was separated from the parent rock, and had doubtless fallen from above. The occurrence in the same slab of a portion of an arm of Ophioderma Milleri and the general character of the stone leave no doubt that it is derived from the “Star-fish” bed of the Capricornus Zone.
