204 BuUetin of Zoological Nomenclature PROPOSED ADDITION TO THE "OFFICIAL UST OF GENERIC NAMES IN ZOOLOGY " OF THE NAMES OF ONE HUNDRED AND TWO GENERA OF CARIDEA (CLASS CRUSTACEA, ORDER DECAPODA), INCLUDING PROPOSALS FOR THE USE OF THE PLENARY POWERS (a) TO VALIDATE THE EMENDATION TO " GNATHOPHYLLUM " OF THE GENERIC NAME « GNATO-PHYLLUM" LATREILLE, 1814, AND (b) TO VAUDATE THE FAMILY-GROUP NAMES " HIPPOLYTIDAE " BATE, 1888 AND " EUGONATONOTIDAE " CHACE, 1937 By L. B. HOLTHUIS {RijksTmiseum van Natuurlijke Historie, Leiden, The Netherlands) (Commission's Reference : Z.N.(S.) 622) I submit herewith to the International Commission on Zoological Nomen-clature a hst of the names of one hundred and two genera of Caridean Crustacea for addition to the Official List of Generic Names in Zoology. Each of these names is an available name in the sense that it is not a homonym of any generic name pre\'iously pubUshed for a genus in the Animal Kingdom. All of these names are currently used in carcinological Iiteratiu"e. The vaUdity of only one among them has been questioned. This one case is dealt with in paragraph 2(1) below. The species indicated here as tj'pe species of the genera enumerated in the list have been duly determined as such under the Regies Internationales de la Nomenclature Zoologique. The gender of each generic name is indicated in brackets immediately after the name concerned. 2. A few cases call for some special comments, which are given here in a separate paragraph before the actual list. These cases are set out below : — (1) Argis Kroyer, 1842 : The name Argis Kroyer, 1842, is rejected by some authors on account of Arges de Haan, 1833. According to the Ragles the difference between the two names is sufficient to let Argis Kroyer st^nd as a valid name (1953, Copenhagen Decisions Zool. Nomencl. : 78, Decision 152). The authors who reject Argis Kroyer, use in its place the generic name Nectocrangon Brandt, 1851 (Middendorff's Reise Sibir. 2(1) : 114) (tj-pe species, by monotypy : Crangon lar Owen, 1839, Zool. Beechey's Voy. Blossom : 88). Argis Kroyer and Nectocrangon Brandt are objective synonjins since they have the same tj'pe species. The name Nectocrangon Brandt, 1851, being an BvU. zool. Nomencl. Vol. 11, Part 7. July 1955.
Proposed addition to the "Official List of Generic Names in Zoology" of the names of one hundred and two genera of Caridea (Class Crustacea, Order Decapoda), including proposals for the use of the plenary powers (a) to validate the emendation to "Gnathophyllum" of the generic name "Gnatophyllum" Latreille, 1814, and (b) to validate the family-group names "Hippolytidae" Bate, 1888 and "Eugonatonotidae" Chace, 1937
