The quarries near Clitheroe and Chatburn supply specimens quite as abundantly as those of Longridge. Innumerable terebratulæ, the beautiful broad-hinged and deeply-striated spirifers, and the euomphalos, reward a very slight amount of labour. Here, too, are countless specimens of the petrified relics of the lovely creatures called, from their resemblance to an expanded lily-blossom and its long peduncle, the crinoidea, a race now nearly extinct. A very curious circumstance connected with these at Clitheroe is that of some of the species, as of the _Platycrinus triacontadactylos_, or the "thirty-rayed," there are myriads of fossilised _heads_ but no bodies. The presumed explanation of this singular fact is, that at the time when the creatures were in the quiet enjoyment of their innocent lives, great floods swept the shores upon which they were seated, breaking off, washing away, and piling up the tender and flowerlike upper portions, just as at the present day the petals of the pear-tree exposed to the tempest are torn down and heaped like a snowdrift by the wayside, the pillar-like stems remaining fast to the ground. There is no need to conjecture where the _bodies_ of the creatures may be. At Castleton, in Derbyshire, where the encrinital limestone is also well exhibited, there are innumerable specimens of these, and few or no examples of heads. The bodies of other species are plentiful at Clitheroe, where the actinocrinus is also extremely abundant, and may be detected, like the generality of these beautiful fossils, in nearly every one of the great flat stones set up edgeways in place of stiles between the fields that lie adjacent to the quarries.
