Show 394 PROF. F. JEFFREY BELL ON THE [May 1, fixity of tenure in zoology, no certainty that the doctrines accepted to-day will not be derided to-morrow ; most m e n of science see this and act accordingly ; the systematic specialist is apt to forget it, and to bear himself as though the motto of his science were " Quod semper, quod ubique, quod ab omnibus." I cannot but hope that the description I have given of the very remarkable Ophiuroid which I have called Ophiocrene cenigma will result in the search for more, and perhaps more fully matured, specimens ; it is a matter of regret that the material is not sufficient to allow of a complete judgment as to the systematic position of what all will allow to be a very remarkable form.
