Extract

The purpose of this note is to place on record two rare crinoids and a blastoid recently found at Coplow Knoll, Clitheroe. One of the crinoids belongs to a new species of Camerata now named Steganocrinus westheadi in honour of its finder, Mr. Stanley Westhead, of Clitheroe. The genus Steganocrinus has not hitherto been recorded from English Carboniferous rocks so that its occurrence at Coplow is noteworthy. The other crinoid, here temporarily assigned to “Pachylocrinus” conicus (Phillips), shows a considerable portion of the arms and was found by the author on a visit to Coplow last year. No other specimen of this species so complete has yet been recorded. On a later visit in the autumn of the same year a single finely preserved specimen of a blastoid was found. In its general characters this specimen does not appear to differ from Orophocrinus pentangularis (Miller), and in ordinary circumstances would call for no special comment here. Blastoids, however, are so rare at Coplow that the occurrence of this specimen, the only one ever found by the author at, or known to him from, this locality, is deemed worthy of record.
