Bulletin of Zoological Nomenclature 67 PROPOSED USE OF THE PLENARY POWERS (a) TO VALIDATE THE GENERIC NAME " LEPIDURUS " LEACH, 1819, AND TO DESIGNATE A TYPE SPECIES FOR, AND TO DETERMINE THE GENDER OF, " TRIOPS " SCHRANK, 1803 (CLASS CRUSTACEA, ORDER PHYLLOPODA) AND (b) TO VALIDATE THE FAMILY NAME "APODIDAE " HARTERT, 1897 (CLASS AVES) By L. B. HOLTHUIS (Rijksmuseum van Natuurlijke Historie, Leiden, The Netherlands) and FRANCIS HEMMING, C.M.G., C.B.E. (Lond<m) (Commission Reference : Z.N.(S.) 1020) Introductory The controversy existing amongst carcinologists as to the correct names that have to be applied to the two Phyllopod genera that by different authors have been indicated as Apos, Apus, Binoculus, Lepidurus or Triaps, has caused a considerable instabiUty in the nomenclature of this group. Furthermore this question not only concerns carcinological, but also involves ornithological nomenclature. Therefore a final decision on this problem by the International Commission on Zoological Nomenclature is highly desirable. 2. The following are the references to Crustacean genera dealt with in this proposal : Apiis Schaeffer, 1756, Krebsart. Kiejeyifuss : 131 (type species, by selection by E. Desmarest (1858, Chenu's Ency. Hist. nat. (Crust.) : 59) : Apu^ cancri-formis Bosc [1801-1802] Hist. nat. Crust. 2 : 244) (gender : masculine) Binoculus Geoffroy, 1764, Hist. dbrg. Ins. Env. Paris 2 : 658 (type species, by selection by Fowler (1912, Ann. Rep. New Jersey State Mus. 1911 : 466) : Monoculus apus Linnaeus, 1758, Syst. Nat. (ed. 10) 1 : 635) (gender : masculine) Binoculus Miiller (O.F.), 1776, Zool. dan. Prodr. : 200 (type species, by selection by Fowler (1912, Ann. Rep. New Jersey State Mus. 1911 : 466) : Binoculus palustris Miiller (O.F.), 1776, Zool. dan. Prodr. : 200 (a junior objective synonym of Monoculus apus Linnaeus, 1758) (gender : masculine) BuU. zool.

Proposed use of the plenary powers (a) to validate the generic name "Lepidurus" Leach, 1819, and to designate a type species for, and to determine the gender of, "Triops" Schrank, 1803 (Class Crustacea, Order Phyllopoda) and (b) to validate the family name "Apodidae" Hartert, 1897 (Class Aves)
