This study is a revision of the poorly known genus Pseudochitinopoma Zibrowius, 1969 (Annelida, Serpulidae), erected for Hyalopomatopsis occidentalis Bush, 1905 from the West Coast of North America. Subsequently, an unnamed Pseudochitinopoma sp. nov. from the Seychelles (ten Hove 1994) (described herein as P. amirantensis sp. nov.) and P. pavimentata Nishi, 1999 were added to the genus. Ficopomatus capensis Day, 1961 is herein referred to Pseudochitinopoma, based on examination of the type material. Finally, Pseudochitinopoma beneliahuae sp. nov. was described from Western Australia and the Red Sea. Reproductive patterns and phylogenetic affinities of Pseudochitinopoma spp. are discussed.

Occigamasus n. gen., O. lindquisti n. sp. and O. makarovae n. sp. from Vancouver Island (Canada) and Oregon (U.S.A.) are described. Five other new species and their sites are noted but not enough specimens were available for adequate descriptions. Cycetogamasus californicus (Banks) sensu Hennessey and Farrier, 1988 is transferred to Occigamasus as a new combination.

The native and naturalized species of Silene L. in southern Africa are reviewed, with full synonomy and the description of two new species from the West Coast of Western Cape. Eight native species and three naturalized species are recognized, including the first identification in southern Africa of the Mediterranean S. nocturna L. The identity of S. aethiopica Burm., which has remained unknown since its description, is established and is found to be the oldest name for S. clandestina Jacq. Patterns of morphological variation within each species are discussed and subspecies are recognized for geographically segregated groups of populations that are ± morphologically diagnosable. The following new names or combinations are made among the southern African taxa: S. aethiopica subsp. longiflora; S. burchellii subsp. modesta, subsp. multiflora, and subsp. pilosellifolia; S. crassifolia subsp. primuliflora; S. saldanhensis; S. rigens; and S. undulata subsp. polyantha. Each taxon is described, with information on ecology and distribution, and most species are illustrated, including SEM micrographs of the seeds.

Two new deep-living species of the genus Bargmannia (Siphonophorae, Physonectae, Pyrostephidae) are described based, almost exclusively, on the nectophores of single specimens collected by ROVs off the west coast of California. The nectophores of B. stenotes sp. nov. were relatively small, up to 11.4 mm in length and, in the preserved condition had very narrow nectosacs. There was a marked bend in the distal part of the preserved nectophore, resulting in the ostium opening upwards. The mature nectophores of B. profunda sp. nov. were almost twice as long as those of B. stenotes and were characterised by the fact that the lower lateral ridges did not join, distally, with the meso-lateral ones. This feature also was present in smaller nectophores of B. amoena but those of B. stenotes, at that stage, did not have a mouth-plate.

The Hanford Brook Formation, one of the classic Cambrian units of Avalonian North America, contains at least eight species of endemic trilobites, including Berabichia milleri Westrop n. sp., that are assigned to seven genera. The vertical succession of faunas is far more complex than has been recognized previously, with each member containing a lithofacies-specific assemblage. These are, in ascending order: a bradoriid-linguloid Association without trilobites in the nearshore St. Martin's Member, a Protolenus Association in dysaerobic siltstones and sandstones of the Somerset Street Member, and a Kingaspidoides-Berabichia Association in hummocky cross-stratified sandstones of the Long Island Member that overlie a parasequence boundary at Hanford Brook. Due to the breakdown of biogeographic barriers in the late Early Cambrian, two new species-based zones, the Protolenus elegans and Kingaspidoides cf. obliquoculatus zones, share trilobite genera with the Tissafinian Stage of Morocco. This generic similarity has been the basis for correlation of this upper Lower Cambrian interval on the Avalon continent with the West Gondwanan lowest Middle Cambrian. However, the clear facies control on the occurrence of genera in the Hanford Brook Formation and the presence of an abrupt faunal break and unconformity at the base of the Tissafinian in Morocco makes this correlation questionable. The Hanford Brook Formation may represent a late Early Cambrian interval unknown in Gondwana. Sequence-stratigraphic criteria even raise the possibility that the Protolenus Association is the biofacies equivalent of Callavia broeggeri Zone faunas of the Brigus Formation of Newfoundland, Nova Scotia and Massachusetts.

Peniculus asinus, a new species of copepod parasitic on Sebastes (Pisces: Teleostei) off the Pacific coast of Canada is described and illustrated. The copepod is an unique member of its genus in that it possesses cephalothoracic holdfast processes. The discovery of a Peniculus with these processes is taken as evidence confirming the place of this genus in the family Pennellidae.

Six nephtyid species were identified from samples collected off the west coast of Saudi Arabia. Two of these species had been previously reported for the Red Sea (Inermonephtys aff. inermis, Nephtys palatii), three are new records (Aglaophamus lobatus, A. cf. verrilli, Micronephthys stammeri) and one is new to science (Inermonephtys aramco). Inermonephtys aramco was collected in the southern region of the Red Sea at depths between 60 and 83 m. It is characterized by the presence of branchiae from chaetiger 15 or 16, well-developed parapodial prechaetal lamellae, broadly rounded notopodial postchaetal lamellae and rudimentary neuropodial postchaetal lamellae. The species Nephtys palatii is transferred to the genus Micronephthys. Based on the current finding, the previously known bathymetric range of Micronephthys stammeri is extended from 4–7 to 17 m, and occurrence depths for N. palatii are given for the first time (4–90 m). Full descriptions are included for all species except M. stammeri. An identification key for all the species known to occur in the Red Sea is provided.

My last general paper on Florida Coleoptera was prepared in the autumn of 1924, and appeared in the Canadian Entomologist for July, 1925. Since that was written my time has been largely devoted to the final preparation and publication of the “Heteroptera of Eastern North America.” During the three years which have elapsed I have spent the winters at Dunedin on the west coast of Florida, but have made three additional collecting trips, of three or four weeks each, to Royal Palm Park. One of these was in December, the other two in March and April. This park comprises an area of 4,000 acres lying in extreme southern Florida, about 40 miles northeast of Cape Sable.

New portunoid fossils from southern Argentina and from the west coast of North America permit the reevaluation of the generic and family relationships within the Portunoidea Rafinesque, 1815. It has previously been suggested that the Portunidae and the Geryonidae Colosi, 1923, are closely related families (Manning and Holthuis, 1989). The new fossils suggest that the Geryonidae may in fact be derived from a portunid progenitor,ProterocarcinusFeldmann, Casadío, Chirino-Gálvez, and Aguirre Urreta, 1995, through a process of peramorphosis in which juveniles of the geryonid speciesChaceon peruvianus(d'Orbigny, 1842) resemble adults ofProterocarcinus latus(Glaessner, 1933). Examination of several genera within the portunid subfamily Polybiinae Ortmann, 1893, includingImaizumilaKarasawa, 1993;Megokkosnew genus;MinohellenusKarasawa, 1990;PororariaGlaessner, 1980;PortunitesBell, 1858; andProterocarcinus,suggests that the subfamily had an amphitropical distribution early in its history. New taxa reported here includeMegokkosnew genus andPortunites nodosusnew species. New combinations includeChaceon peruvianus(d'Orbigny, 1842),Imaizumila araucana(Philippi, 1887),Megokkos alaskensis(Rathbun, 1926),Megokkos hexagonalis(Nagao, 1932),Megokkos macrospinus(Schweitzer, Feldmann, Tucker, and Berglund, 2000),Minohellenus triangulum(Rathbun, 1926), andProterocarcinus latus(Glaessner, 1933).
