Since that time many new genera and higher cate¬ gories were described within the Caridea and Stenopodidea, and the original paper, out of print for a considerable time, also became badly out of date. Therefore, it was decided to issue this second edition with the list of genera updated, with the infor¬ mation overlooked in the first edition added, and the errors corrected. The original project was started in 1953 with the primary object of producing a key to the genera of the infraorders Caridea and Stenopodidea of the suborder Natantia Boas, 1880, a group consisting of animals commonly known as shrimps and prawns, which forms part of the order Decapoda Latreille, 1802. Later it was felt that the paper would be of more use to zoologists, if also the synonymies and other parti¬ culars of the genera were given. So gradually the paper has become mainly a list of the genera of the Caridea and Stenopodidea, while the keys to these genera are of secondary importance. Fossil genera are not included in the present list. Nomina nuda also are omitted if they could not definitely be assigned to known genera. A list of the dubious genera is given on p. 304. The Amphionididae, treated in the first edition as Caridea of uncer¬ tain status, in 1973 were elevated by Williamson (1973, Crustaceana, 25: 35-50) to the rank of a separate order, Amphionidacea, next to the order Decapoda. Williamson's views are accepted here, and the Amphionidacea are removed from the Caridea, and treated separately in an Appendix. In the previous edition the Decapoda were considered to consist of three subor¬ ders (Macrura, Anomura and Brachyura), following the classification adopted by Bouvier (1917, Resultats Campagnes scientifiques Monaco, 50). The suborder Macrura was then divided into two groups: the Natantia and the Macrura Reptantia. In the present account the Natantia and Macrura Reptantia are considered full suborders of equal rank with the Anomura and Brachyura. I know that this classification will gen¬ erally be considered old-fashioned: in several modern handbooks the suborder Natantia has been abandoned altogether; a small part of it, namely the Penaeoidea is elevated to the rank of a separate suborder Dendrobranchiata, while the rest of the Natantia plus the Macrura Reptantia, plus the Anomura, plus the Brachyura, are placed in a single suborder Pleocyemata. This to me seems a very artificial and unsat¬ isfactory arrangement, and I therefore still keep to the old classification. For the pur¬ poses of the present publication this makes little difference, as the infraorders Caridea and Stenopodidea are recognized in both systems. In the following text all genera of Caridea and Stenopodidea known to me are enumerated. Of each the valid name and its synonyms are listed. Emendations of these names (i. e., demonstrably intentional spelling changes; the intent of the change RECENT GENERA OF CARIDEAN AND STENOPODIDEAN SHRIMPS 7 must be clearly stated in the original publication), being available names (Inter¬ national Code of Zoological Nomenclature, Art. 19), are treated as synonyms. On the other hand, incorrect spellings (see International Code, Art. 19 and Glossary) are unavailable names and have no status nomenclaturally. They are printed here in small type and listed (with their original reference) immediately following the correctly spelled name. These erroneous spellings are mentioned in the present publication to show their unavailable status, as some have been used over long periods (e.g., Hoplo- phorus for Oplophorus). I do have to admit that this collecting of erroneous spellings became something like a hobby. A hobby, however, which shockingly shows how careless some authors are in the use of scientific names. It is true, however, that not all errors can be blamed on the authors, as shown by the following peculiar example: in the case the erroneous spelling Peltesamonae for Palaemonetes, it seems likely that someone without access to the manuscript (type setter's help, errand boy?) dropped the type (which at that time was hand-set from separate letters) and put the letters back in a haphazard way, without mentioning this mishap and evidently without being caught in time. Of all generic names the original publication is cited. Of each genus is mentioned the type species, the method in which the type is fixed, and the gender of the name. If relevant, the nomenclatural status of the name is discussed, e.g., when the names are suppressed under the plenary power of the International Commission on Zoological Nomenclature, or placed by the Commission on the Official List of Generic Names in Zoology, or on the Official Index of Rejected and Invalid Generic Names in Zoology. The number of the Opinion (or Direction) in which these decisions by the Commis¬ sion were made known is indicated with the year in which the Opinion or Direction was published. More details about these Opinions and Directions can be found in the bibliography (p. 318, under Opinion, or Direction) as well as in "Official Lists and Indexes of Names and Works in Zoology" edited by R.V. Melville and J.D.D. Smith and published in 1987 by the International Trust for Zoological Nomenclature (c/o The Natural History Museum, Cromwell Road, London SW7 5BD, U.K.). Etymology. An attempt has been made to provide the etymological derivation of each generic name. This, of course, is easy when such an explanation of the name is given by the original author in the original, or a subsequent publication (such cases are marked here with "(e)" after the word Etymology), or in a personal communica¬ tion (marked "(e')" here). In the other cases (marked "(i)") the meaning of the name is inferred. The abbreviations Gr. and L. are used to indicate whether a word is Greek or Latin. Where appropriate, the derivation given in the original publication is quot¬ ed verbatim from the original description. In quotations from later sources, a refer¬ ence to these sources is given. In studying the meaning of the scientific names, the work by Ronald W. Brown (1956) "Composition of Scientific Words"(second edition) proved invaluable, actually without it I would never have set out on this task. As an aid to the identification of the genera, a figure of each, preferably of the type species, is provided. Most figures are taken from existing publications; the few originals are always indicated as such. The schematic figure of the external shape of a shrimp (fig. 1) and that of the structure of a leg (fig. 2) will explain most, though not all, of the technical terms used in the keys. For the explanation of the other terms, like those dealing with mouth- 8 L.B. HOLTHUIS: Fig. 1.

Subgenera, whether or not valid, are treated as synonyms of the genera to which they belong; the subgenera considered valid here are entered into the keys. Of each family dealt with here, it has been tried to provide a complete synonymy, including incorrect spellings. The International Code of Zoological Nomenclature specifies (Art. Ilf) that the valid name of a family-group taxon is the oldest latinized name that was based on an available generic name and was clearly used to denote a suprageneric taxon, regardless of the latin ending used for that name, and regardless of the rank assigned to the suprageneric category to which the name was given. De Haan's family name Atyadea and Rafinesque's subfamily name Alphidia are available family names, the endings of which have to be emended (to Atyidae and Alpheidae respectively). Also the name Palaemones given by Van der Hoeven (1827, Handboek der Dierkunde, (first edition) 1: 434) to a "phalanx" (a category equivalent to the pre¬ sent suborder Natantia), could have been used for a family name (Palaemonidae), were it not that it has older synonyms (and homonyms). According to Article 36 a of the International Code, the oldest available family-group name has to be used with the original author (but with the appropriate ending) for any family-group taxon, at whatever rank, that contains the type genus on which the name is based. Therefore the family name Palaemonidae, the subfamily name Palaemoninae and the superfam¬ ily name Palaemonoidea, all have as author Rafinesque, 1815. RECENT GENERA OF CARIDEAN AND STENOPODIDEAN SHRIMPS 9 Fig. 2. Schematic drawing of a thoracic leg. The names of taxa higher than the family group are not regulated by the Code. In the present paper there are only four such names: Natantia (suborder), Caridea and Stenopodidea (both infraorders), and Amphionidacea (class). The well known name Natantia Boas, 1880, is used here in preference to the oldest name for the suborder, Carides Latreille, 1817, which in the last century has never been used for it. This also prevents a confusion with the name Caridea Dana, 1852, which is the oldest name of an infraorder of the suborder Natantia. Replacement names for Caridea Dana, like Eucyphotes (and Eukyphotes) Boas, 1880, Eucyphidea Ortmann, 1890, and Eukyphida Burkenroad, 1963, are not required by the International Code and moreover have not generally been accepted. The two other names above those of the family group, Stenopodidea and Amphionidacea, are both based on family names. One could, in keeping with the rules for the family names, consider the authors of the family name to be at the same time the author of the name of these higher categories, but it seemed more logical to cite as their author the first zoologist who used such a name for a cate¬ gory above the family group level. 10 L.B. HOLTHUIS: The endings -idae and -inae, for family and subfamily names respectively, are prescribed by Art. 29 (a) of the International Code of Zoological Nomenclature, while the ending -oidea for superfamily names is recommended in Recommendation 29 A of that Article. The ending -idea, which was used in the first edition of the pre¬ sent paper for superfamilies, is used here for infraorders. Acknowledgements A special word of thanks is due to Dr Fenner A. Chace, Jr., Emeritus Zoologist, Department of Invertebrate Zoology, National Museum of Natural History, Smithsonian Institution, Washington, D.C., who, with his usual unselfishness, placed valuable manuscript notes and information at my disposal (both for the first and the second edi¬ tion) and made several corrections in the text of my manuscript; the present form of the key to the caridean families is practically literally taken from his recent paper on the subject (Chace, 1992, Crustaceana, 63 (1): 70 - 80). I am also very much indebted to Mr Charles H.J.M. Fransen, who succeeded me as curator of Crustacea of the National Museum of Natural History at Leiden. Mr Fransen put the entire first edition on a disk, convinced me that I should use a word processor, taught me its principles and always was ready to help in the many cases that I got stuck. He also gave excellent advice and helped greatly with the illustra¬ tions, several of which are originals from his hand. Mr G.R. Heerebout (Kloetinge) kindly permitted the use of some of his excellent unpublished illustrations of North Atlantic species. For the explanation of the etymology of a number of names I had the greatly appreciated cooperation from many persons, who in several cases that I could not solve, came with solutions or probable solutions, which greatly diminished the num¬ ber of complete enigmas. Prof. Dr Corrie C. Bakels (Leiden), Dr Frederick M. Bayer (Washington, D.C.), Mr G.N. Cherry (Eastbourne, U.K.), Prof. Jacques Forest (Paris), Mr J.C. den Hartog (Leiden), Dr Raymond W. Ingle (Robertsbridge, East Sussex, U K.), Dr Gerhard Pretzmann (Vienna), and Dr C. Smeenk (Leiden) greatly helped me with their knowledge of mythology, classical languages and history, to find solu¬ tions which often had completely escaped me. Dr Fenner A. Chace, Jr. (Washington, D. C.), in reading an early version of the manuscript, corrected many of my errors in Latin and Greek, and suggested a great number of possible derivations of puzzling names, for which I am deeply indebted to him. It is inevitable that there are errors and omissions in this paper; the author will be grateful for any corrections and additions.

The species of the present suborder, like all other Decapoda, were placed by Lin¬ naeus (1758, Syst. Nat., (ed. 10) 1: 625-634) in the genus Cancer. Fabricius (1775, Syst. Ent.: 413-18) erected a new genus Astacus, which contained all of the Natantia, in addi¬ tion to the Astacidea, Palinuridae, Hippidea, Squillidae, Euphausiacea and some Am- phipoda. In 1798 the Natantia were placed by Fabricius (Suppl. Ent. Syst.: 402-410) in the genera Palaemon, Alpheus, Penaeus, and Crangon. The order Decapoda was first erected by Latreille (1802, Hist. nat. Crust. Ins., 3: 20), who subdivided this order into two "sections": the "Brachyures" and the "Macroures". The genera of Natantia of course were included in the latter group; they were placed, together with the astaci- dean genera, in the family "Homardiens; Astacini". Leach (1814, Edinburgh Encycl., 7: 398-402) also included in this family, which he named // Astacini ,, / the Mysidacea and the Thalassinidea. Latreille (1816, Cuvier's Regne anim., (first edition) 3: 35-38) was the first to treat the Natantia as a unit, to which he gave the vernacular name "Salicoques", and which he made a section of his family "Decapodes macroures". In 1817 the same author (Latreille, Nouv. Diet. Hist, nat., 18: 358) gave this section the Latin name "Cari¬ des". In the German edition of Cuvier's Regne animal, Schinz (1823, Cuvier's Thier- reich, 3: 51) gave the group the latinized name "Salicoqui", while Van der Hoeven (1828, Handboek Dierkunde (ed.l), 1: 434) named it "Palaemones" or "Carides". A great variety of other names has been given to the group by later authors. H. Milne Edwards (1837, Hist. nat. Crust., 2: 338-431) divided the family "Salico¬ ques" into four tribes, the "Crangoniens", "Alpheens", "Palemoniens" and "Peneens". Though McLeay (1838, Illustr. Annul. South Africa: 54) gave very few details of his tribe Caridea, it evidently is identical with Latreille's Carides. De Haan (1849, Fauna Japon., Crust., (6): 167) in general followed H. Milne Edwards, the group "Salicoques" is called by him "Macroura Carides", and is divided into five families: Palemonidea, Alpheidea, Crangonidea, Atyadea and Penaeidea. Dana (1852, U. S. Explor. Exped., 13: 501) was the first to make a sharp distinction between the penaeids and stenopodids (grouped by him in the subtribe Penaeidea) on the one hand, and the Caridea on the other. Dana also was the first to use the term Caridea in the sense in which it is now generally adopted. It is interesting to note that the same author (Dana, 1852, Proc. Acad. nat. Sci. Philadelphia, 6: 15) in an earlier publication used the term Caridea for the entire group of the Natantia, and that he divided his "subtribus" Caridea into three "legiones": Palaemoninea, Pasiphaeinea and Penaeinea. Huxley (1879, Proc. zool. Soc. London, 1878: 785) divided the Decapoda in two large groups according to the structure of their gills: the carideans were placed in his Phyllobranchiata, while the penaeids and stenopodids were ranged under his Trichobranchiata. Like Huxley, Bate (1888, Rep. Voy. 12 L.B. HOLTHUIS: Challenger, Zool., 24: xi-xiii, 6) attached much value to the structure of the gills for the classification of the Decapoda, and he divided the suborder Macrura into four tribes: the Trichobranchiata, in which he placed the stenopodids, the Dendrobranchiata to which the peneids were assigned, the Phyllobranchiata consisting of the carideans and some larval forms, and the Anomobranchiata, containing the Stomatopoda. Boas (1880, K. Danske Vidensk. Selsk. Skr., (6) 1 (2): 28,155,164) grouped the Decapoda in two sub¬ orders: the Natantia and the Reptantia. He is the original author of the term Natantia which he used in the sense adopted here. Practically all subsequent authors, e.g., Ortmann (1890, Zool. Jb. Syst., 5: 437), Alcock (1901, Descr. Catal. Indian Deep Sea Crust. Decapoda Macrura Anomala: 9), Borradaile (1907, Ann. Mag. nat. Hist., (7) 19: 467), Caiman (1909, Lankester's Treatise Zool., 7: 310), Bouvier (1917, Res. Camp. sci. Monaco, 50: 8), Balss (1927, Kiikenthal & Krumbach's Handbuch Zool., 3 (1): 998), fol¬ low Boas in considering the group Natantia a unit, though they give it different names and place it at different levels in the system of the Decapoda. Cams (1885, Prodr. Faunae Mediterraneae, 1:470) recognised the Sergestidae as a distinct family and placed all the other Natantia in the family Carididae. Beurlen & Glaessner (1930, Zool. Jb. Syst., 60: 49-84) in a revolutionary new classification of the Decapoda, broke up the Natantia. They placed the tribes Penaeidea and Stenopodidea in the section Nectochelida of their suborder Trichelida, while the Caridea under the name of Eucyphidea form a tribe of the section Anomocarida of the suborder Heterochelida; all of their suborders and sec¬ tions are proposed as new by Beurlen & Glaessner. Their classification, however, was rejected by most authors and in the authoritative accounts by Balss (1957, Bronn's Klassen und Ordnungen des Tierreichs, (second edition) 5 (1) (7) (12): 1514-1672), and Waterman & Chace (1960, in Waterman, Physiology of Crustacea, 1: 23-26), the Deca¬ poda are divided into two suborders Natantia and Reptantia, and the Natantia into three tribus or sections (the present infraorders) Penaeidea, Caridea, and Stenopodidea. This concept is also adopted in the present publication. A revolutionary change in the Decapod classification was proposed in 1963 by Burkenroad (1963, Tulane Studies in Geology, 2 (1): 1-17). Burkenroad divided the order Decapoda into two suborders: Dendrobranchiata consisting of Waterman & Chace's Section Penaeidea, and Pleo- cyemata containing all other Decapoda. The Pleocyemata were divided by Burkenroad into the two "supersections" Natantia and Reptantia; the Natantia were subdivided into the "sections" Eukyphida [ = Caridea] and Stenopodida. Glaessner (1969, in R.C. Moore, Treatise on Invertebrate Paleontology, (R4) 2: 446-533) accepted Burkenroad's suborders Dendrobranchiata and Pleocyemata. He replaced the term section with infraorder and recognized in the Pleocyemata the following infraorders: Stenopodidea, Caridea, Astacidea, Palinura, Anomura, and Brachyura, eliminating the groups "Natantia" and "Reptantia". In 1981 Burkenroad (Trans. San Diego Soc. nat. Hist., 19 (17): 251-268) revised his 1963 classification and now recognized 4 suborders in the Order Decapoda, viz., Dendrobranchiata (= Penaeidea), Euzygida (= Stenopodidea), Eukyphida (= Caridea), and Reptantia (= the old suborder Reptantia of Boas, 1880). Bowman & Abele (1982, in Bliss, Biology of Crustacea, 1: 21-25) largely followed Glaessner (1969): in the order Decapoda they distinguished two suborders, the Dendrobranchiata Bate, 1888 (= Penaeidea) and the Pleocyemata Burkenroad, 1963 (which Burkenroad himself had abandoned the year before). In the Pleocyemata they recognized the same infraorders as did Glaessner (1969), with the only difference that they considered the Thalassinidea to be a separate infraorder, distinct from the Anomura. The last word certainly has not RECENT GENERA OF CARIDEAN AND STENOPODIDEAN SHRIMPS 13 been spoken about decapod taxonomy. The classification adopted in the present paper is one of convenience and makes no pretention of being based on phylogenetic con¬ cepts. The definition of the Natantia as given by Caiman (1909, Lankester's Treatise Zool., 7: 310) is as follows: "Body almost always laterally compressed; rostrum usually compressed and ser¬ rated; first abdominal somite not much smaller than the rest; antennules generally with stylocerite; antennal scale generally large and lamellar; legs usually slender, ex¬ cept sometimes a stout chelate limb or pair, which may be any one of the first three pairs, with basipodite [= basis] and ischiopodite [= ischium] very rarely coalesced and with only one fixed point in the carpo-propodal articulation (with some doubt¬ ful exceptions), sometimes with exopodites [= exopods], podobranchiae hardly ever present on the first three and never on the last two pairs; male genital apertures in articular membrane; pleopods always present in full number, well developed, used for swimming." The suborder Natantia is divided into three infraorders: Caridea, Stenopodidea and Penaeidea. In previous publications the terms tribe and section have often been used for infraorder. During the 14th International Congress of Zoology held in 1953 in Copenhagen, however, it was decided that the term tribe is to be used only for cate¬ gories below the subfamily level; therefore the term tribe was replaced by that of sec¬ tion in the first edition of the present publication. However, in the latest, third, edition of the International Code the term section is considered to be that of a subdivision of a genus or subgenus. Glaessner (1969) thus was quite correct in introducing the name infraorder for this category; he was followed in this by Bowman & Abele (1982). Key to infraorders of Natantia. 1.

Eukyphida Burkenroad, 1963, Tulane Studies in Geology, 2 (1): 2,4,10,11,13. As has been pointed out above, Dana (1852) was the first to regard the present group as a distinct unit and he gave it the name Caridea. I can find no good reason not to use the name proposed by Dana, the more so since there are no definite rules for the nomenclature of groups above family level. Dana's name is the first ever used to denote this group, it is short, euphonious and is not in use at present for any other group in the Animal Kingdom. Boas's (1880: 163, footnote) rejection of Dana's name and his substitution of the name Eukyphotes for it because "le nom Carides donne par M. Dana a cette division est employe par d'autres auteurs pour tous les Sali- coques (y compris les Penees)" is not based on any definite rule or common practice, and therefore is not followed here. If Boas's reasons for rejecting the name Caridea were considered valid, then also the name Penaeidea has to be rejected: when origi¬ nally proposed by Dana, that taxon also contained the genus Stenopus, which at pre¬ sent is placed in a separate infraorder Stenopodidea. Dana (1852) divided his subtribe Caridea into four families: Crangonidae (with the subfamilies Crangoninae, Lysmatinae and Gnathophyllinae), Atyidae (with the Atyi- nae and Ephyrinae), Palaemonidae (with the Alpheinae, Pandalinae, Palaemoninae, and Oplophorinae), and Pasiphaeidae. Dana's subfamilies agree well with the families of our present system; he included, however, the genus Regulus (= Thalassocaris) in the Oplophorinae, and the genus Nika (= Processa) in the Lysmatinae, while the hippolytids are placed partly in the subfamily Lysmatinae and partly in that of the Alpheinae. Bate (1888, Rep. Voy. Challenger, Zool., 24: 480,481) divided his Phyllobranchiata Normalia, which coincide exactly with Dana's Caridea, into four "tribes". These tribes are the Crangonidea (containing the family Crangonidae), the Polycarpidea (consisting of the families Nikidae, Alpheidae, Hippolytidae, and Pandalidae), the Monocarpidea (with the families Thalassocaridae, Atyidae, Pontoniidae, Caricyphidae, Acanthephyridae, Palaemonidae, Nematocarcinidae, Tropiocaridae, Stylodactylidae, Pasiphaeidae, and Oodeopidae; the last named family at present is placed in the Thalassinidea), and the Haplopodea (containing only the family Hectarthropidae). The family Nikidae differs from our present Processidae by containing, in addition to the genus Nika (= Processa) that of Glyphocrangon. The families Caricyphidae, Oodeopidae, and Hectarthropidae consist entirely of larval forms, while also several genera based on larvae are (correctly or incorrectly) inserted in other families. The families Acanthephyridae and Tropioca¬ ridae at present are combined and bear the name Oplophoridae, while the Pontoniidae at present are considered to be only a subfamily of the Palaemonidae. Ortmann (1890) divided the Caridea, which he named Eucyphidea, into 13 families: Pasiphaeidae, Atyidae, Alpheidae, Thalassocaridae, Pandalidae, Hippolytidae, Rhynchocinetidae, Pontoniidae, Hymenoceridae, Palaemonidae, Nikidae, Crangonidae, and Gnathophyl- lidae. His family Atyidae consisted of two subfamilies, Ephyrinae and Atyinae. Later Ortmann (1896, Zool. Jb. Syst., 9: 421-425) revised his classification somewhat. He sepa¬ rated the Acanthephyridae as a distinct family from the Atyidae (the Nematocarcini¬ dae were considered by him only a subfamily of the Acanthephyridae). The Thalasso- RECENT GENERA OF CARIDEAN AND STENOPODIDEAN SHRIMPS 15 caridae were assigned to the Pandalidae as a subfamily, Thalassocarinae. A new family Latreutidae was erected for the Hippolytidae with a simple mandible. Finally the name Nikidae was changed to Processidae, and the name Gnathophyllidae to Drimo- idae. In 1898 Ortmann (Bronn's Klassen und Ordnungen des Thierreichs, (first edition) 5 (2): 1122-1133) recognised a third subfamily, Notostominae, in the Acanthephyridae and furthermore listed the families Stylodactylidae and Psalidopodidae. The Drimo- idae are again named Gnathophyllidae. Borradaile (1907) divided the Caridea (named Carides by him) into seven superfamilies: Pasiphaeoida (containing the Bresiliidae and Pasiphaeidae), the Hoplophoroida (with the Hoplophoridae, Nematocarcinidae, and Atyidae), the Stylodactyloida (containing only the Stylodactylidae), the Psalido- podoida (with only the Psalidopodidae), the Pandaloida (with the Pandalidae), the Palaemonoida (with the Alpheidae, Hippolytidae, Rhynchocinetidae, and Palaemoni- dae), and the Crangonoida (with the Gnathophyllidae, Processidae, Glyphocrangoni- dae, and Crangonidae). Borradaile divided the family Pandalidae into two subfamilies: the Pandalinae and the Thalassocarinae, as Ortmann (1896) had already done before him. The family Palaemonidae was divided into three subfamilies: Palaemoninae, Pontoniinae, and Hymenocerinae. Borradaile did not include in his classification the family Disciadidae erected in 1902 by Rathbun (Proc. Washington Acad. Sci., 4: 289) for her new genus Discias. In 1913 Sollaud (Bull. Mus. Hist. nat. Paris, 19: 184) founded a new family Campylonotidae for the genus Campylonotus Bate, while in 1915 Borradaile erected the family Anchistioididae for Anchistioides Paulson. Balss (1927, Kiikenthal & Krumbach's Handbuch Zoologie, 3 (1): 1000-1003) gave a classification of the Caridea (named Eucyphidea by him) which is largely based on Borradaile's system, to which the three families just mentioned were added. The family Ogyridae of Hay & Shore (1918, Bull. U. S. Bur. Fish., 35: 388) was not accepted by Balss as distinct from the Alpheidae. Balss placed the Disciadidae and the Campylonotidae in the superfamily Hoplophoroida, while the Anchistioididae were assigned to the Crangonoida. The Thalassocaridae were again given the full rank of a family, the Hymenocerinae were combined with the Gnathophyllidae, while the family Palaemonidae was divided into four subfamilies Desmocaridinae, Palaemoninae, Typhlocaridinae, and Pontoniinae. The first of these four subfamilies was established by Borradaile (1915, Ann. Mag. nat. Hist., (8) 15: 206), the third by Annandale & Kemp (1913, Journ. Proc. Asiatic Soc. Bengal, (n. ser.) 9 (6): 245). Later, Chace (1936, Journ. Washington Acad. Sci., 26: 25) established the family Eugonatonotidae under the name Gomphonotidae, and the family Physetocaridae was proposed by Chace in 1940 (Zoologica, New York, 25:196). The classification of the Caridea adopted in the first edition of the present paper (Holthuis, 1955, Zoologische Verhandelingen Leiden, 26: 7-142) was admittedly not a natural one, and many improvements have later been suggested for it. In this first edi¬ tion the Caridea were divided into 9 superfamilies: Oplophoroida (with the families Oplophoridae, Nematocarcinidae and Atyidae), Stylodactyloida (fam. Stylodactylidae), Pasiphaeoida (fam. Pasiphaeidae), Bresilioida (fam. Bresiliidae, Disciadidae, Eugona¬ tonotidae, Rhynchocinetidae), Palaemonoida (fam. Campylonotidae, Palaemonidae, Gnathophyllidae), Psalidopodoida (fam. Psalidopodidae), Alpheoida (fam. Alpheidae, Ogyrididae, Hippolytidae, Processidae), Pandaloida (fam. Pandalidae, Thalassocaridi- dae, Physetocarididae), and Crangonoida (fam. Glyphocrangonidae, Crangonidae). Balss (1957, Bronn's Klassen und Ordnungen des Tierreichs, (second edition) 5 (1) (7) (12): 1522-1558), who used the name Eucyphidea for the present group, adapted 16 L.B. HOLTHUIS: Borradaile's (1907) system to the increased knowledge of the Caridea. He recognized 8 superfamilies: Amphionelloida (with family Amphionellidae), Pasiphaeoida (with Pasiphaeidae and Bresiliidae), Hoplophoroida (with Atyidae, Hoplophoridae, Nema¬ tocarcinidae, Disciadidae, Campylonotidae and Rhynchocinetidae), Stylodactyloida (monotypic), Pandaloida (with Eugonatonotidae, Pandalidae and Physetocarididae), Psalidopodoida (monotypic), Palaemonoida (with Alpheidae, Hippolytidae, Palae- monidae), Crangonoida (with Processidae, Gnathophyllidae, Glyphocrangonidae, Crangonidae). Yaldwyn (1960, Bull. New Zealand Dept. sci. industr. Research, 139 (1): 16) united the Eugonatonotidae and Rhynchocinetidae to a single family, Rhynchocinetidae. Thompson (1967, Proc. Symposium Crustacea Emakulam, India, 1: 314-326) revised the arrangement proposed by Holthuis (1955) by removing the Nematocarcinidae from the Oplophoroidea and by placing them in the Bresilioidea together with the Bresiliidae and the Disciadidae. The Eugonatonotidae, on the other hand were placed by him in the Oplophoroidea. A new superfamily Heterocarpodoidea [recte: Heterocarpoidea] was established by him for the families Heterocarpodidae [recte: Heterocarpidae], the Campylonotidae (removed from the Palaemonoidea) and the Rhynchocinetidae (removed from the Bresilioidea). In 1971 a most aberrant Caridean was discovered in an anchialine habitat in the mid-Atlantic island of Ascension. It was described by Chace & Manning (1972, Smithsonian Contrib. Zool., 131: 6-12) as a new species belonging to a new genus Procaris, which represents a new family Procarididae and a new superfamily Procari- doidea. Two more species of the genus were found shortly afterwards (1973 and 1986), while in 1986 a new genus Vetericaris Kensley & Williams was added to the family. Forest (1977, Bull. Mus. Nat. Hist. nat. Paris, (3) 475 (= Zool. 332): 869-888) dis¬ cussed the status of the superfamily Bresiloidea and came to the conclusion that it should be abandoned. He placed the Disciadidae (in which family the genus Lucaya, removed from the Bresiliidae, was incorporated by him), the Bresiliidae and the Nematocarcinidae in the superfamily Oplophoroidea, while the Eugonatonotidae and Rhynchocinetidae were assigned to the Palaemonoidea. Bowman & Abele (1982, in Bliss, Biology of Crustacea, 1: 22) divided the infraorder Caridea into 11 superfamilies (Procaridoidea, Atyoidea, Stylodactyloidea, Pasiphae- oidea, Rhynchocinetoidea, Palaemonoidea, Psalidopodoidea, Alpheoidea, Pandaloi- dea, Physetocaridoidea, and Crangonoidea), thus two more than recognized in the first edition of the present paper, which was followed in most instances. The differences are that the superfamilies Procaridoidea and Physetocaridoidea are added, the last split off from the Pandaloidea; the family Disciadidae is not recognized, and for the superfami¬ lies Oplophoroidea Dana, 1852 and Bresilioidea Holthuis, 1955, correctly the older names Atyoidea De Haan, 1849, and Rhynchocinetoidea Ortmann, 1890, have been substituted. Hart & Manning (1986, Journ. Crustacean Biol., 6 (3): 411) established the family Agostocarididae for their new genus Agostocaris, which was later placed by Chace (1992, Crustaceana, 63 (1): 72) in the Bresiliidae. In various papers published between 1987 and 1990, Christoffersen studied with cladistic methods various groupings within the Caridea with most unexpected results. In 1987 (Cladistics, 3 (4): 348-363) the superfamilies Crangonoidea and Alpheoidea RECENT GENERA OF CARIDEAN AND STENOPODIDEAN SHRIMPS 17 were examined. In the former the families Barbouridae (corrected to Barbouriidae in 1990), Lysmatidae, Processidae and Crangonidae were recognized, while to the Alpheoidea were assigned the families Nauticarididae, Alopidae, Bythocarididae, Thoridae, Hippolytidae (with the subfamilies Latreutinae and Hippolytinae), and Alpheidae. In 1988 (Revista Nordestina de Biologia, 6 (1): 43-59) the family Crango¬ nidae was subdivided into the subfamilies Pontocaridinae, Philocherinae [ recte: Philocheradinae ], Pontophilinae, Paracrangoninae, and Crangoninae. The superfamily Pandaloidea was revised by Christoffersen in 1989 (Cladistics, 5: 259-274); the follow¬ ing families were recognized within this superfamily: Pandalidae (with subfamilies Pantominae and Pandalinae, the latter divided into two tribus Austropandalini and Pandalini), Plesionikidae, Heterocarpidae, Heterocarpoididae, Dorodoteidae [ recte: Dorodotidae], Thalassocarididae, and Physetocarididae. In the same year Christof¬ fersen (1989, Boletim Zoologia Univ. Sao Paulo, 10: 273-281) revised the superfamily Atyoidea and recognized in it the following families: Oplophoridae, Atyidae (with subfamilies Atyinae and Xiphocaridinae), Pasiphaeidae, Alvinocarididae, Bresiliidae, Psalidopodidae, and Disciadidae. Finally, in 1990 (Christoffersen, 1990, Zeitschr. zool. Systematik Evolutionsforschung, 28: 94-106) the above conclusions were brought together in a complete review of the superfamilies and families of the Caridea. Here, the family Agostocarididae was added to the Atyoidea, in which superfamily also the genus Kirnasin Burukovsky, 1988, was placed as Atyoidea incertae sedis . The super¬ family Stylodactyloidea contained the two families Stylodactylidae and Campylono- tidae. The Palaemonoidea consisted of the families Palaemonidae and Rhynchocineti- dae only. The Eugonatonotidae and the Nematocarcinidae were both elevated to the rank of a monotypic superfamily, Eugonatonotoidea and Nematocarcinoidea, respec¬ tively. The arrangement of the Pandaloidea was as in 1989, but to the Crangonoidea the families Merguiidae and Glyphocrangonidae were added. The arrangement of the Alpheoidea differed from that proposed by Christoffersen in 1987 by the addition of the families Merhippolytidae, Pterocarididae and Ogyrididae, while the genus Yagero- caris was considered to belong to the "Alpheoidea incertae sedis . The great diversity of opinion among authors about the place and composition of the various families and superfamilies within the Caridea and the juggling around of the various taxa, led to considerable confusion. It was felt as a relief therefore, when very recently an up to date classification of the Caridean families was published by Chace (1992, Crustaceana, 63 (1): 70-80). This classification is conservative compared to some of the previously published schemes, but it is sensible and well reasoned. Chace's arrangement has been adopted in the present paper. The last tens of years saw a sharp increase in the known number of species, gen¬ era, and even families of Caridea. This is mostly due to a more intensive exploration of numerous habitats all over the world, while more sophisticated collecting equip¬ ment made many niches accessible that formerly could not be reached. It seems like¬ ly that this trend will continue and that many more facts will come to light. It can be expected therefore that the conclusions concerning the classification of the Caridea that are reached today, will become obsolete by the evidence that will be found tomorrow. The following key to the subfamilies, families and superfamilies of Caridea is largely based on the one published by Chace (1992, Crustaceana, 63 (1): 74-80), large 18 L.B. HOLTHUIS: parts of which are quoted verbatim. Chace's key is far more elaborate than the pre¬ sent one; it, and Chace's text should be consulted by anyone interested in the classifi¬ cation of the higher taxa of Caridea.

Record (Crust., for 1984), 121 (10): 372 In the first edition of this paper 8 genera of Pasiphaeidae were recognized. Since that time the genus Sympasiphaea has been synonymized with Ghjphus. After Crosnier & Forest (1973, Faune Tropicale, 19: 149) suggested the possibility of this synonymy, it was definitely established by Takeda & Masahito (1982, Mem. Nat. Sci. Mus. Tokyo, 15:181-185). Another doubtful genus is Dantecia Caullery, 1896, which since its description has not been reported again. The only actual difference with Parapasiphae mentioned by Caullery (1896, Ann. Univ. Lyon, 26: 372) is the fact that the mandibular palp in Dantecia is one-segmented, while in Parapasiphae it consists of two segments. Kemp (1910, Sci. Invest. Fisher. Branch Ireland, 1908 (1): 53, pi. 5 fig. 21) already pointed out that in Parapasiphae sulcatifrons S.I. Smith, 1884, the number of segments in the mandibular palp is rather variable: although in adults almost always two segments are present, sometimes, like in younger specimens, the palp is one-segmented, e.g., in an Irish specimen of 38 mm. Unfortunately, Caullery gave no exact measurements of his single specimen, but judging by his figures, of which he gives the enlargement, it is about 35 mm in total length. The great importance for Pasiphaeid taxonomy that in Caullery’s times was attached to the number of segments of the mandibular palp later proved to be misplaced. As I have been unable to find any other reliable differ¬ ence between Dantecia and Parapasiphae, I am compelled here to synonymize the two. In 1976, Chace (Smithsonian Contrib. Zool., 222:1-48) in his revision of Leptochela, divided that genus into two subgenera, Leptochela s.s. and the new Proboloura. The six genera and two subgenera of Pasiphaeidae known at present can be dis¬ tinguished with the help of the following key. 1. Mandible without a palp. Rostrum formed by an erect postfrontal spine. . Pasiphaea 24 L.B. HOLTHUIS: 2 . Mandibular palp present. Rostrum a normal forwards directed prolongation of the carapace . 2 Fourth pereiopod distinctly shorter than either third or fifth leg.3 Fourth pereiopod longer than fifth leg, though sometimes shorter than third .5 3.

In accordance with Art. 27 of the International Code of Zoological Nomenclature which forbids the use of diacritic marks in scientific names, the spelling of the pre¬ sent name should be changed to Eupasiphae; the first correct use of this name known to me is by Tirmizi (1969, Crustaceana, 16 (2): 213-217).

In the 1955 edition of this paper the family Atyidae was placed in the superfami¬ ly Oplophoroidea Dana, 1852, together with the families Oplophoridae Dana, 1852, and Nematocarcinidae S.I. Smith, 1884. Bowman & Abele (1982) accepted that arrangement, but correctly used the superfamily name Atyoidea for it as Atyidae De Haan, 1849, has priority over Oplophoridae Dana, 1852. Chace (1992, Crustaceana, 63 (1): 70-76) assigned the Atyidae and Oplophoridae each to their own monotypic superfamily. Chace's arrangement is followed here.

Serie caridinienne Bouvier, 1925, Encycl. entomol., (A) 4: 42,122. The genera of the Atyinae can be distinguished with the help of the following key, which is partly based on that by Chace (1983, Smithsonian Contr. Zool., 384: 2-4). 1. Carpus of first and second pereiopods similar, both deeply excavate and little, if at all, longer than wide .2 - Carpus of second pereiopod different, usually strongly so, from that of first pereiopod, not deeply excavate and distinctly longer than wide .6 2. Third maxilliped with terminal spine. Endopod of first pleopod of male tapering from base to tip .•••..3 - Third maxilliped ending in numerous stout setae, but lacking a single terminal spine. Endopod of first pleopod of male expanded into a broad lamina.5 3. Pterygostomian margin of carapace broadly rounded. Chelae not heteromorphic, adapted for filter feeding. Appendix interna of second male pleopod not reach¬ ing the distal spinose part of the appendix masculina. Epipods on third and fourth pereiopods strongly reduced; no mastigobranchs present . Australatya Pterygostomian margin narrowly rounded to sharply acute. Chelae heteromor¬ phic, adapted for filter or substrate feeding. Appendix interna of second male pleopod reaching beyond the base of the spinose area of the appendix masculina. Epipods on first to fourth pereiopods well developed; mastigobranchs on all pereiopods .........4 4. Pterygostomian margin rounded. First pereiopod without arthrobranch . . Archeatya - Pterygostomian margin dentate or angular. First pereiopod with arthrobranch. . Atyoida 5. Telson with posterolateral angles not overreaching the posterior margin. Third pereiopod of large males without massive spur on merus. Epipods on third and fourth pereiopods well developed. Mastigobranchs on all pereiopods. Atya - Telson with posterolateral angles produced backward beyond the posterior margin of the telson. A massive spur on the merus of the third leg in large males. Epipods on third and fourth pereiopods vestigial. Mastigobranchs absent . . Atyopsis 6. Palmar portion of chelae distinct; dactylus of these chelae much shorter than propodus. Rostrum generally laterally compressed and with teeth on both upper and lower margin, seldom unarmed on one or both margins. Carpus of second chelipeds hardly if at all excavate anteriorly. Africa, Indo-West Pacific region .... 7 - Palmar portion of chelae very small; dactylus of these chelae almost as long as the propodus. Rostrum short, in the basal part dorsoventrally depressed and without dorsal, though with ventral teeth. Carpus of second chelipeds generally distinctly excavate anteriorly. America.8 7.

Mus., 6:160 (a junior sub¬ jective synonym of Atya pilipes Newport, 1849, Ann. Mag. nat Hist., 19: 160). Gender: feminine. Etymology (i): evidently named after William Kissam Vanderbilt (1878-1944), owner and commander of the yacht "Alva", in which in 1931 a world cruise was made during which the type material of the type species was collected. It is possible, as suggested by Dr Fenner A. Chace (in litt.), that the name was intended to honour William K. Vanderbilt's second wife, Mrs. Rosamund Lancaster Warburton, for whom certainly the type species, be it incorrectly spelled rosamon¬ dae, was named.

Name suppressed for the purposes of the Principle of Priority but not for those of the Principle of Homony¬ my under the plenary power of the International Commission on Zoological Nomenclature, and placed on the Official Index of Rejected and Invalid Generic Names in Zoology in Opinion 522, in 1958. Etymology (i): from Symethus or Symaethus fluvius, the ancient Latin name for the river which at present is named Simeto, and which is found in eastern Sicily, Italy; it empties into the Bay of 60 L.B. HOLTHUIS: Catania somewhat south of the town of Catania. Most likely the Simeto is the type locality of Symethus fluviatilis. According to Agassiz (1846, Nomenclator Zoolo- gicus. Index Universalis: 357, footnote a), the name is derived from Symaithos (Gr.), a "nomen proprium". Erroneous spelling of Symethus Rafinesque, 1814: Symathus Rafinesque, 1815, Analyse Nature: 98, 221.

Etymology (i): according to Agassiz (1842-1846, Nomen¬ clator Zoologicus, Coleoptera: 2) the name Acilius is derived from Acilia, a "nomen proprium". Dr R.W. Ingle pointed out to me (in litt.) that the name might have been derived from the name of the Roman historian Acilius Glabrio. Symaethus Agassiz, 1846, Nomencl. Zool., Index Univ.: 357. Invalid emendation of Symethus Rafinesque, 1814, Precis de Decouvertes somiologiques: 23. Type species therefore: Symethus fluviatilis Rafinesque, 1814, Precis Decouvertes somiologiques: 23. Gender: masculine. The generic name Symaethus Agassiz, 1846, is an available name and is older than the name Atyaephyra de Brito Capello, 1867. It should therefore have to replace the latter, were it not that itself is a homonym of another Symaethus Agassiz, 1846, which Agassiz proposed as an emendation for Symethis Fabricius(1798, Suppl. Entomol. Syst.: 371; Crustacea, Decapoda, Brachyura, Raninoidea). Thus there are two generic names Symaethus Agassiz, established on the same date in the same work on the same page. According to Art. 24(a) of the International Code of Zoological Nomenclature, the relative precedence of these two homonyms is determined by the action of the first reviser. So far as is known Fig. 46. Atyaephyra desmarestii (Millet, 1831). After Holthuis, in H. Boschma (ed.). Fauna van Nederland, 15: 24, fig. 7. RECENT GENERA OF CARIDEAN AND STENOPODIDEAN SHRIMPS 61 to me no action in this respect has ever been taken, and therefore, acting here as the first reviser, I give the name Symaethus Agassiz, 1846, proposed as an emenda¬ tion for Symethis Fabricius, 1798, precedence over Symaethus Agassiz, 1846, pro¬ posed as an emendation of Symethus Rafinesque, 1814. The last named of these two Symaethus now has to be treated as an invalid junior homonym and thus can¬ not replace the currently used name Atyaephyra de Brito Capello, which remains the valid name for the present genus.

In the classification of the superfamily Palaemonoidea the arrangement suggest¬ ed by Chace (1992, Crustaceana, 63 (1): 73-83) has been adopted here. This arrange¬ ment differs in several points from that used by me in 1955 in the first edition of this paper. The family Campylonotidae is removed from the Palaemonoidea and given a separate superfamily. Each of the genera Anchistioides, Desmocaris, Hymenocera and Typhlocaris is placed in a family of its own, and the subfamily Euryrhynchinae is assigned, with the Typhlocaridinae, to the family Typhlocarididae.

For a long time the hymenocerids have been placed in the family Gnathophyllidae, but recently Chace (1992, Crustaceana, 63 (1): 73, 78) showed that two distinct families are involved. The Hymenoceridae contain two genera Hymenocera and Phyllognathia, which can be distinguished as follows: 1. Outer antennular flagellum normal in shape, thread-like. Chelae of second legs broad and flat, but not leaf-shaped. Last two segments of the third maxilliped, although broad, not broader than the antepenultimate segment... Phyllognathia - Outer antennular flagellum deformed by the extreme broadening of the larger part of its segments to a broad, flat, leaf-shaped appendage. Chelae of second legs also leaf-shaped, because the lower border is produced to a large, thin flap. Last two segments of the third maxilliped distinctly broader than the antepenul¬ timate segment .

In the first edition of this list the number of Pontoniine genera was cited as being considerable. At that time the exact number was 32. Since that time the genus Anchistioides has been removed to a separate family Anchistioididae. Intensive inves¬ tigations in the subfamily Pontoniinae, especially by Dr A.J. Bruce of Darwin, Australia, more than doubled the number of known genera of this subfamily, which now is 71. In a few cases the splitting may have been too fine, but in the present list all new genera are accepted at their face value. In the following key it is tried to dis¬ tinguish all 71. Due to the great number of monotypic genera, the characters used in the key may be more of a specific than of a generic nature. The key thereby is rather one to the type species of the genera than to the actual genera themselves. Therefore, it should be used with a great deal of reserve. 1 . 2 . 3 .

Miami, 16 (3): 595, 596, 597. Gender: feminine. Etymology (e‘): from ana (Gr.), = up, back, again, and the generic name Pontonia (p. 168); to indicate the genus as belonging to the Pontoniinae, with the prefix chosen for euphony.

Name placed on the Official List of Generic Names in Zoology in Opinion 470, in 1957. Etymology (i): possibly from the generic name Anchistia (p. 163) with the suffix -ia changed to -us. In the same paper the generic name Anchistia Dana, 1852, was synonymized with Periclimenes Costa, 1844, and thus disappeared as an invalid junior synonym. Another explanation might be that Anchistus is a latinization of anchistos (Gr.), = nearest; perhaps in reference to its being close to other pontoniine genera, like Harpilius.

Dr Gerhard Pretzmann of the Vienna Museum (in litt.) suggested that Pesta may have named the genus for Mary Jane Rathbun, who in 1906 had fin¬ ished her impressive monograph of the freshwater crabs, a group in which Pesta was much interested. Pesta had a good contact with Miss Rathbun, who after World War I helped the Pesta family with food packages. Ensiger Borradaile, 1915, Ann. Mag. nat. Hist., (8) 15: 207.

Etymology (e): "dal greco tujctoo pulso, percuoto: cosi detto a cagione dello scroscio" (Costa, 1846, Fauna del Regno di Napoli (Crostacei,Tiptone): 1), meaning: from typto (Gr.), = to beat, to strike; in reference to the cracking or snapping sounds that it is supposed to produce; also Nardo (1869, Mem. 1st. Veneto Sci. Lett. Art., 14: 323) mentioned the fact that the species with its large cheliped did strike the bottom of the jar in which it was kept and RECENT GENERA OF CARIDEAN AND STENOPODIDEAN SHRIMPS 179 that for that reason it had been given the specific names pulsator and pulsatrix.

Crustacea, Ernakulam, India: 5. The superfamily Alpheoidea was first recognized as a distinct taxon in the first RECENT GENERA OF CARIDE AN AND STENOPODIDEAN SHRIMPS 187 edition of the present paper. The families Alpheidae, Ogyrididae and Hippolytidae, which until then were placed in the superfamily Palaemonoidea, were considered enough distinct to form their own superfamily. The family Processidae, until then considered as belonging to the superfamily Crangonoidea, was also included in the Alpheoidea. Chace (1992: 71, 73, 79) accepted this arrangement except for the posi¬ tion of the Processidae, which were assigned by him to a superfamily of their own, the Processoidea. In the present paper Chace's classification is followed. Family Alpheidae Rafinesque, 1815 Alphidia Rafinesque, 1815, Analyse Nature: 98.

Halopsyche is an incorrect origi¬ nal spelling of Halopsyche, as according to Art. 27 of the International Code of Zoological Nomenclature no diacritic mark is to be used in a scientific name, and the incorrect spelling has to be automatically corrected.

Etymology (i): from the Anglo-Saxon word thunor for thunder, an equivalent of the old norse word thor; as the genera Thunor and Thor (p. 250) belong to different families (Alpheidae and Hippolytidae respectively) and also otherwise have little in com¬ mon, it is unlikely that the choice of the name Thunor was meant to indicate a rela¬ tionship with Thor; it is possible, however, that the name Thunor was selected to indicate the noise that this snapping shrimp can produce with its chelae.

Etymology (i): Although Dana did not give the derivation of this name, I cannot escape the feeling that it is the subject of a little joke by Dana, who fabricated it by replacing the "Alpha" in Alph[a]eus by the Greek letter "Beta". It is not advis¬ able for other zoologists to continue this little game, as the name Gammaeus too closely resembles that of Gammarus and could cause confusion.

The name Jousseaumea Coutiere, 1897, is placed on the Official Index of Rejected and Invalid Generic Names in Zoology in Opinion 673, in 1963. Etymology (i): named after Dr Felix-Pierre Jousseaume (1835- 1921), French physician and well known malacologist, who between 1889 and 1900 214 L.B. HOLTHUIS: undertook several collecting trips to the Red Sea, during which he obtained the type material of the two species that Coutiere (1897) brought to his new genus Jousseaumea.

Etymology (i): from the generic name Homarus (Crustacea Decapoda, Nephropoidea), and that of Alpheus (p. 190); possibly because in this alpheid the "brephalos" (i.e., the just hatched ani¬ mal) is a megalopa, like in the Trichobranchiata (and thus in Homarus), while Bate thought that it consistently was a zoea in Alpheus.

According to Brown (1956, Compo¬ sition of scientific words (second edition): 463, 699, 802) latreutes is a (hired) ser¬ vant, and cultor a husbandman, planter or tiller, or an inhabitant or dweller; nei¬ ther word makes much sense for the present genus, unless, as Dr R.B. Manning suggested (in litt.), it is a reference to the fact that the type species is an inhabitant of the floating Sargassum weed. It would be more logical if cultor stood for knife- bearer, culter (L.) being knife; this would fit nicely with the specific name ensiferus, which also means knife-bearer; the word knife would then refer to the shape of the rostrum of the type species.

After Hart & Manning, 1981, Journ. Crustacean Biol., 1 (3): 443, fig. 1. Names in Zoology in Opinion 588, in 1961. Etymology (i): named after James Sowerby (1757-1822), a well known British naturalist and artist, who in all proba¬ bility described the type species of this genus. Spirontocaris Bate, 1888, Rep. Voy. Challenger, Zool., 24: 576, 595. Type species, by monotypy: Cancer Spinus Sowerby, 1805, British Miscellany, (4): 47. Gender: femi¬ nine. Name placed on the Official List of Generic Names in Zoology in Opinion 588, in 1961. Etymology (e): "From G7tetp(DV , a sower", and karis (Gr., latinized to caris), = a shrimp; there are strong indications that Bate at first wanted to name the genus Sowerbyus, but finally refrained from it because of the existence of a genus named Sowerbya d'Orbigny, 1850; it is possible that by translating Sower of Sowerby to speiron. Bate tried to stay close to his first choice of name. He may have considered speironto the genitive of speiron. In the Greek dictionaries con¬ sulted by Dr Frederick M. Bayer (Washington, D.C.) and myself the Greek word for sower is given as sporeus, not speiron; the latter word is said to mean cloth; but the verb speiro (Gr.) indeed does mean to sow. Was Bate mistaken in his choice of a Greek word? There can hardly be any doubt, however, that he meant the generic name to mean Sower shrimp or perhaps Sowerby's shrimp.

Name placed on the Official List of Generic Names in Zoology in Opinion 470, in 1957. Etymology (e): "Thor, a Scandinavian deity", in Norse mythology Thor, the god of thunder, was one of the most important deities; Thursday is named after him. See also Thunor in the synonymy of Alpheus (p. 194). Erroneous spelling of Thor Kingsley, 1878: Tor Balss, 1915, Denkschr. Akad. Wiss. Wien, 91: 25. Paschocaris Nobili, 1905, Bull. Mus. Hist. nat. Paris, 11: 395. Type species, by original designation and monotypy: Hippolyte paschalis Heller, 1862, S.B. Akad. Wiss. Wien, 44 (1): 276. Gender: feminine. Etymology (i): the first half of the generic name Paschocaris is probably inspired by the specific name paschalis of its type species. In latin paschalis is the equivalent of the English term "paschal",, meaning "of or belonging to the Pesach (= Passover, = Jewish Easter)", the Jewish celebration of the exodus of the Israelites from Egypt and their passage through the Red Sea. As the type materia] of Hippolyte paschalis was collected in the Red Sea, the possibility exists that Heller (1862) chose the name on this account. Unfortunately Heller gave no indication where the species was collected other than that it came from the RECENT GENERA OF CARIDE AN AND STENOPODIDEAN SHRIMPS 251 Fig. 249. Thor paschalis (Heller, 1862). After Kemp, 1914, Rec. Indian Mus., 10: pi. 1 fig. 6. Red Sea, neither did he say who collected it and when. In his introduction Heller only stated that part of his material was collected by G. Ritter von Frauenfeld, who visited the Red Sea in the spring (around Easter?) of 1855. If von Frauenfeld indeed collected the material around Easter, the name paschalis may be derived from that fact. It is less likely that the name paschalis was given in honour of an official help¬ ful in collecting the material; pascha is the German spelling of pasha, a title in the Ottoman Empire given to high government officials like military commanders or governors of provinces. In the introduction of his short narrative of the collecting trip to the Red Sea, von Frauenfeld (1855, Sitzungsber. Akad. Wissensch. Wien, mathem.-naturwiss. Classe, 18 (1): 66, 67) devoted almost a whole page to the mer¬ its of the vice-roy Abbas Pasha, under whose government many roads were con¬ structed and improved, greatly facilitating travel in the area. The new Hippolyte might possibly have been dedicated to him. The suffix -caris (L.), = shrimp. How careful one has to be in drawing conclusions on the origin of scientific names is shown by the fact that the locality in which von Frauenfeld collected most of his material is called by him Tor or Thor (at present named A1 Tur or Et Tur), where he collected during three weeks. This possible type locality of Thor paschalis has noth¬ ing to do with the generic name Thor for the genus, as Kingsley (1878), when coin¬ ing the name, definitely explained its derivation from the name Thor of the Norse deity, and he even did not include Heller's species in his genus.

Etymology (e): "Tti^eupa, telum". Most dictionaries give the meaning of the Greek word toxeuma as arrow, and that of the latin word telum as spear. The name evidently is given for the elongate body with the long triangularly spear-shaped rostrum of the type species. As the correct translitera¬ tion of the Greek word cited by Stimpson (1860) is Toxeuma rather than Tozeuma, Henderson (1893, Trans. Linnean Soc. London, (2) (Zool.) 5 (10): 437), thought Toxeuma Stimpson,1860 the correct name and rejected it as a junior homonym of Toxeuma Walker (1833, Entomol. Mag., 1 (4): 378) (Insecta Hymenoptera); he used the oldest synonym Angasia for the present genus. However, Art. 32c(ii) of the International Code of Zoological Nomenclature makes clear that an incorrect transliteration is not to be considered an inadvertent error and should not be cor¬ rected. The spelling Tozeuma thus is correct and should be used. Erroneous spellings of Tozeuma Stimpson, 1860: Toxeuma Henderson, 1893, Trans. Linnean Soc. London,(2) (Zool.) 5 (10): 437.

Name placed on the Official List of Generic Names in Zoology in Opinion 104 (in 1928) and in Direction 47 (in 1956). Etymology (i): the derivation of the name Pandalus forms an intriguing problem, like the derivation of so many of Leach's nice and well sounding generic names. Agassiz (1842-1846, Nomenclator Zoologicus, (Crust.): 21) suggests "pandalitos [Gr.], omnia laedens", laedens then referring to laedo (L.), = to injure, which seems not to make much sense. According to Mr G.N. Cherry, from whom I received much help in such questions, pandalitos means laurel-crowned, which might refer to the teeth on rostrum and carapace. He also drew my attention RECENT GENERA OF CARIDEAN AND STENOPODIDEAN SHRIMPS 273 Fig. 272. Pandalus montagui Leach, 1814. a, animal in lateral view; b, left second pereiopod. After Holthuis, 1950, in H. Boschma (ed.). Fauna van Nederland, 15: 30, fig. 8. to the explanation by K.A. Andersson (1942, Fiskar och Fiske i Norden, 1: 296), who considered pandalus a diminutive form of pandus (L.) for curve or bump, which might refer to the third abdominal somite which Leach (1814: 432) described as "gibbous above", a feature which inspired the British name Aesop-prawn for the type species. Another theory is that Pandalus is a, possibly intentional, misspelling of Pandarus, in Greek mythology, the name of a fighter in the Trojan war. It also might be a variant spelling of the Greek word pandelos, meaning visible to all. As so often, Leach keeps us guessing.

In the first edition it was pointed out that our knowledge of the Crangonid gen¬ era, and especially that of the Crangon-Notocrangon-Sclerocrangon and Pontophilus- Pontocaris groups, was quite imperfect. In the mean time several authors have occu¬ pied themselves with these groups. Zarenkov (1965, Zool. Journ. Moscow, 44) took the courageous step to tackle the Crangon group of genera, and established several new genera, all of which are recognized here, even though not all of Zarenkov's conclu¬ sions are accepted. His actions set in motion a closer study of the various genera by later authors, who added to them and remodeled several. Due to our imperfect knowledge of the important characters of many of the species, the situation still is not quite satisfactory, although considerably improved. The Pontocaris group was studied by Chace (1984, Smithsonian Contrib. Zool., 397), who resurrected Parcipontocaris. Recent studies by de Saint Laurent and Chan shed more light on the group. Kemp (1910, Sci. Invest. Fisher. Branch Ireland, 1908 (1): 143-166), basing himself on North Atlantic material, originally had the idea that Pontophilus and Philocheras are two dis¬ tinct genera. But when he went to India and studied the Crangonidae there the sharp lines between the two genera became obscured by the many new species that he found. This resulted in his action to synonymize the two genera (Kemp, 1911, Rec. Indian Mus., 11: 5-12). However, still later the idea that Pontophilus and Philocheras are distinct genera again gained gradual acceptance, especially among European authors. Pontophilus as seen by Kemp (1910) and others is a well defined genus, although Christoffersen (1988, Revista Nordestina Biologia, 6 (1): 46) split the genus in two, by erecting the new genus Parapontophilus. Philocheras, however, has received less atten¬ tion than Pontophilus and still is a mishmash, which eventually may fall apart into several genera. In the key to the genera given here it has been tried to include all the genera established since 1955. Whether the characters used are always the correct ones is up to future workers to prove or disprove. It is hoped that the key may form a challenge to them; if they tear it apart so much the better. 1. Second pereiopods wanting. Paracrangon Second pereiopods present .2 2.

Etymology (i): in Greek mythology Aegaeon (also spelled Egeon, Aegeon and Aigaion) is a hundred-armed giant, son of Uranos and Gaia, and was nicknamed by the gods Briareos, i.e. the terri¬ ble; he was one of the three Hekatoncheirs (those with hundred hands) and in this group represented the enormous natural force of the waves. Risso (1826, Hist. nat. Europe meridionale, 5: 58) explained Egeon as "Dieu marin". Aegaeon Agassiz, 1846, Nomencl. Zool. Index Univ.: 8, 134. Emendation of Egeon Bose, 1813, Nouv. Bull. Sci. Soc. philom. Paris, 3 (66): 233. Type species therefore: Cancer cataphractus Olivi, 1792, Zool. Adriatica: 50. Gender: masculine. Aegaeon is an avail¬ able name, and can therefore be used to replace the invalid Egeon. However, it is a homonym of Aegaeon Agassiz, 1846, Nomencl. Zool. Index Univ.: 8, 134, which is an emendation by Agassiz of the generic name Egeon de Montfort, 1808. As the two homonyms were published simultaneously by Agassiz, it is up to the first reviser to select one and treat the other as a junior homonym. So far as I know this has not happened before, and therefore, acting as the first reviser, I now select Aegaeon Agassiz, the replacement name for Egeon Bose, 1813 (cited as Egeon Risso, 1816) to have precedence over Aegaeon Agassiz, the replacement name for Egeon de Montfort, 1808. In this way the name Aegaeon can be used, be it in a slightly differ¬ ent spelling for the genus that for more than 100 years has been indicated with that name. This is the more justifiable as recent investigations by Mme M. de Saint Laurent and Dr Tin-Yam Chan have shown that Aegaeon and Pontocaris are distinct 286 L.B. HOLTHUIS: genera.

Tidsskr., 4: 256, footnote) remarked that before he decided that his material of the type species of Argis belonged to Cancer lar Owen, 1839, he thought it to be new and intended to give it the specific name argilicola, as his material was found on a muddy bottom ("Leerbund"). One wonders whether the name Argis is also inspired on the Latin word argilla for clay and that it is some sort of contraction (e.g., of argillicaris, for mud shrimp, to give a far-fetched guess).

Etymology (i): in Greek mythology Mesapus, or its better known variants Mes- sapus or Messapos, is the name of a prince from Boeotia (modern name: Voiotia, a province NW of Athens), for whom the mountain Messapion in that province, and possibly the district of Messapia in S Italy (where Messapos went when leav¬ ing Boeotia), are named.

Tidsskr., 4: 231 (a junior subjective synonym of Pontophilus bispinosus Hailstone, 1835, Mag. nat. Hist., 8: 271). Gender: masculine. Etymology (i): from philos (Gr.), = friendship, esteem, and cheras (Gr.), = silt, mud; this might indi¬ cate that the species are mud dwellers, but more likely the name Philocheras is formed by interchanging the two parts of the generic name Cheraphilus Kinahan, 1862 (p. 298, under Pontophilus), which incorrectly was used for species of the present genus.

(Assigned by Bate, 1888, to the Hippolytidae, but Caiman, 1906, Ann. Mag. nat. Hist., (7) 17: 34, doubts this and is inclined to consider the genus more closely related to Nematocarcinus). Etymology (e): from "apcpurArjKTOQ, compressed on both sides"; possibly in reference to the compressed shape of the body, although this character is not mentioned in the description.

(Pandalidae; based on a larval stage). Etymology (i): possibly from copia (L.), = abundance, and caris (L.), = shrimp; this might refer to the number of specimens in the type lot of the type species, Thiele mentioned several, but did not indicate the exact number. Dr F.A.Chace drew my attention to the fact that the Greek word kopion means "small oar"; none of the legs of Thieles type species ends in a flattened top like seen in species of E retmocaris, and from the description it is not clear what struc¬ ture could be meant with the term oar. The derivation of the name for the time being remains a problem. Coronocaris Ortmann, 1893, Ergebn. Plankton-Exped., 2 (Gb): 73, 81. Type species, des¬ ignated by Holthuis (1955, Zool. Verh.

Type species, by monotypy: Oligocaris bispinosa Ortmann, 1893, Ergebn. Plankton-Exped., 2 (Gb): 85. Gender: feminine. (Pandalidae; based on a larval stage). Etymology (i): from oligos (Gr.), = few, or (sometimes) little, and karis (Gr., latinized to caris), = shrimp; the word few may refer to the number of specimens, but this was at least two as the species was obtained at two stations, no exact numbers are given; also Ortmann's specimens are not particularly small (up to 27 mm) compared with his other larval species; therefore the derivation of the name remains uncertain.

Euzygida Burkenroad, 1981, Trans. San Diego Soc. nat. Hist., 19: 253. Stenopididea Abele, 1991, Mem. Queensland Mus., 31: 102. Until 1878 the Stenopodidea were generally placed in the family Penaeidae. In 1872 Claus considered the Stenopinae a subfamily in the family Carididae. Huxley (1878) raised the group to the rank of a separate family, and Bate (1888) made them a 308 L.B. HOLTHUIS: separate "tribe" in his Trichobranchiata. Though the various authors differed about the place of the Stenopodidea in the classification of the Decapoda (see introduction Natantia), until 1986 there was no difference of opinion about the systematics within the infraorder itself, as all authors then were unanimous in assigning only one family to the Stenopodidea. In 1986 Schram (1986) split off the Spongicolidae as a separate family The two families can be distinguished by the following key. 1. Body compressed. Telson elongate lance-shaped, ending in two strong spines, sometimes with a much smaller spine in between. Endopod of uropod with two longitudinal dorsal ridges. Third maxilliped always with a distinct exopod. ..Stenopodidae Body depressed. Telson broadly lance-shaped or subquadrangular, ending in three to five subequal spines.

Name of genus and of its type species sup¬ pressed for the purposes of the Principle of Priority but not for those of the Principle of Homonymy, under the plenary power of the International Commission on Zoological Nomenclature and placed on the Official Index of Rejected and Invalid Generic (resp. Specific) Names in Zoology in Opinion 522, in 1958. Etymology (i): unknown to me. Agassiz (1842-1846, Nomenclator Zoologicus, (Crust.): 5) gave the derivation 'hyzen [Gr.], densus"; as byzen means dense or close-pressed, it is possi¬ ble that this name refers to the dense spinulation of the body. To suppose that Byzenus was meant as a contraction of Byzantius (= inhabitant of Byzantium, = Istanbul) is too far fetched even taking into account Rafinesque’s special liking for contractions and the fact that Istanbul at that time named Constantinople) was his native town.

Appendix Order Amphionidacea Williamson, 1973 Amphionidea Dana, 1852, U.S.Exploring Exped., 13: 614,1435. Amphionelloidea Balss, 1957, Bronn’s Klassen Ordnungen Tierreichs, (ed. 2) 5 (1) (7) (12): 1525. Amphionidacea Williamson, 1973, Crustaceana, 25 (1): 47. Until recently the Amphionididae were considered a group of uncertain status RECENT GENERA OF CARIDEAN AND STENOPODIDEAN SHRIMPS 317 usually assigned to the Caridea, e.g., by Gurney (1942, Ray Soc., London, 129: 223- 225). For that reason they were listed in the first edition of the present paper under the 'Genera dubia Carideorum". Williamson (1973) elevated the group to the rank of an order next to the Decapoda. Accepting Williamson's views, the information on the Amphionidacea has now been removed from the Caridean text and it was thought best to treat it here separately as an appendix, rather than to eliminate it altogether. The order consists of one known family with a single genus. Family Amphionididae Holthuis, 1955 Amphionidea de Haan, 1849, Fauna Japonica, Crust., (7): 242. Type genus: Amphion H. Milne Edwards, 1833. Amphionidae Dana, 1852, U.S. Exploring Exped., 13:1435. Amphionididae Holthuis, 1955, Zool. Verh. Leiden, 26:139.Type genus: Amphionides Zimmer, 1904. Amphionellidae Balss, 1957, Bronn's Klassen Ordnungen Tierreichs, (ed. 2) 5 (1) (7) (12): 1525. Type genus: Amphionella Balss, 1957. Amphionides Zimmer, 1904 (fig. 312) Amphion H. Milne Edwards, 1833, Ann. Soc. entom. France, 1: 336. Type species, by monotypy: Amphion Reynaudii (correction of the incorrect original spelling Amphion Reinaudii) H. Milne Edwards, 1833, Ann. Soc. entom. France, 1: pi. 12. Gender: mas¬ culine. Invalid junior homonym of Amphion Huebner, 1819, Verz. bekannt. Schmett., (9): 135 (Lepidoptera), and of Amphion Pander, 1830, Beitr. Geogn. Russ.: 139 (Trilobita). Etymology (i): in Greek mythology Amphion is the son of Zeus and Antiope, and husband of Niobe; he was famous for his singing and his lyre music. According to the International Code of Zoological Nomenclature (Art. 32c(ii) and Examples) the original spelling Amphion Reinaudii is an incorrect original spelling as in the text of the paper in which the species is established, H. Milne Edwards (1833: 339) speaks off "mon ami M. Reynaud, a qui je l'ai dediee". Art. 32(d) prescribes the automatic correction of Reinaudii to reynaudii. Amphionides Zimmer, 1904, Zool. Anz., 28: 225. Type species, by monotypy: Amphioni¬ des valdiviae Zimmer, 1904, Zool. Anz., 28: 225. Gender: masculine. Gurney, 1942, Ray Soc., London, 129: 223-225, pointed out that Amphion H. Milne Edwards is the larva of Amphionides Zimmer. Etymology (i): from the generic name Amphion (see previous paragraph) and -ides (Gr.), = suffix meaning son of; in reference to the close relationship of the two genera.

Type species therefore Amphion reynaudii H. Milne Edwards, 1833, Ann. Soc. entomol. France, 1: pi. 12. Etymology (i): from the generic name Amphion (p. 317, under Amphionides), and the diminutive suffix -ella (L.); in order to let the new name resemble the replaced name. 318 L.B. HOLTHUIS: Fig. 312.
