STUBBLEFIELD REGARDING "PELTURA" MILNE EDWARDS, 1840 (CLASS TRILOBITA) By CHRISTIAN POULSEN {Univeraitetets Mineralogiak-Oeologiake Inatitut, Copenhagen) (Commission Reference : Z.N.(S.) 1034) (For tlie proposals in this case see Btdl. zool.

Henningsmoen regarding designation of a type species for Protopeltura Brogger, 1882 (Class Trilobita), and I highly recommend the procedure proposed in connection with this application. (b) (Letter dated 30th October 1956) This letter is written in order to inform the ICZN that I fully support Dr. C. J. Stubblefield's request for the validation under the Plenary Powers of the emendation to Peltura of Peltoura Milne Edwards (H.), 1840 (Class Trilobita) and that I highly recommend the other actions proposed in connection with this matter. SUPPORT FOR THE PROPOSAL BY J. WRIGHT ON "ACTINOCRINUS GILBERTSONI " PHILLIPS, 1836 (CLASS CRINOIDEA) By RAYMOND E. PECK (University of Missouri, Colombia, U.S.A.) (Commission Reference : Z.N.(S.) 1057) (For the proposal in this case see Btdl. zool. Nom&ncl. 12 : 156-158) (Letter dated 15th October 1956) This is to recommend approval of the request of Mr. J. Wright of Edinburgh that the species of Actinocrinus gilbertsoni Phillips be interpreted by reference to the neotype designated by him. Mr. Wright has made a very conscientious search for the holotype and has determined that there is slight possibility that it will ever be found. In these circumstances designation of a neotype by a specialist like Mr. Wright will be of great value to systematists working with Crinoidea.
Support for the proposal by G. Henningsmoen on Protopeltura Brogger, 1822, and for the supplementary proposal by C. J. Stubblefield regarding Peltura Milne Edwards, 1840 (Class Trilobita)
