What are called the pulley, or screw stones, are merely the sharp impressions of encrinital stems, forming solid cylinders, marked with annular risings and depres- sions. The transition limestone (and the slate for- mation in England) are the grand repository of these remains, upward of 50 species, belonging to 25 gen- era, having been collected from these ancient de- posites. They are almost unknown in the upper secondary and tertiary formations ; a fact which, in the opinion of geologists, indicates some remarka- ble change in the physical condition of the waters during these later periods, inimical to the great de- velopment of the crinoidea, which existed in the oceans of the transition era.
