Book Description
Excerpt from The Crinoidea Flexibilia: With an Atlas of A. B. C. And 76 Plates It is a fresh illustration of the growth of knowledge that the division of the Crinoidea which forms the subject of the present memoir was not known at all to the earlier systematic writers who treated of the Class; neither to J. S. Miller, with whose epoch-making monograph the systematic study of the crinoids as a group began nearly a century ago, nor to Johannes Muller, whose masterly researches upon the anatomy of the Echinoderms 20 years later laid the foundation for future investigations upon their structure. The magnitude of the group as now understood is shown by the size of this treatise; and the progress above alluded to is further exemplified by the manner in which the subject has expanded under my hands. When I began the study of the Flexibilia after the death of Wachsmuth in 1896, it was part of a more ambitious plan to work up the two groups remaining after the Camerata; and of these it was supposed that the present group would be relatively a minor undertaking. I estimated that 25 plates would contain all the necessary illustrations, and that these with the text would fall readily within the compass of a single volume. All the known material of this group in the museums of the world at that time did not occupy one-fourth of the space that is now required for the specimens of my own collection. Except for a few species, the Flexibilia are the rarest of all the fossil crinoids, some forms being represented by a single specimen, and most of them by only a few. It was my early perception of the inadequacy of material, of the necessity of making further collections, and of examining as far as possible the types and other specimens from all sources, that has in part caused the long delay in the preparation and publication of this work. Far the greater part of the delay, however, has been due to the desultory character of my studies, arising from causes not within my control. The insistent demands of an exacting profession, and the claims of business affairs which absorbed the major portion of my time, caused frequent and often long breaks in the prosecution of the work, the total of which must be measured by years.
