| Abstract/Notes | Most of the specimens described herein have been in my collection for a long time, but lack of opportunity has prevented their being dealt with until now. Several species still require to be worked out and it is hoped to describe them later. Recently my friend, Mr. Stanley Westhead, of Clitheroe, allowed me the privilege of seeing certain specimens he had collected at Coplow Knoll, and one of these, a new Platycrinus, is described here. Some of the species, especially the Poteriocrinids, are assigned to genera whose validity at present is a matter of doubt. In recent years, American workers have made many changes in the nomenclature of the older Carboniferous genera, restricting some and giving new names to others and under the present disturbed conditions it has not been possible to see all these works some of which have a special bearing on the subject. Lack of reference to the majority of these must therefore be expected. In this connection I wish here to thank Mr. Harrell L. Strimple, of Bartlesville, Oklahoma, for much information and for copies of his papers up to date, as well as for other kindnesses. I have also to thank Dr. A. C. Stephen, of the Royal Scottish Museum, for ready access to specimens under his charge and the authorities of the Museum for permission to figure the specimen shown on PI. XI, figs. 5β8. Thanks are also due to Mr. Tot Lord, of Settle, Yorkshire, for the loan of the specimen shown on PI. IX, figs. 7β9. |
