Orbiniella nuda, new species, is newly described from Washington. Naineris quadricuspida, Pygospio elegans, Pherusa negligens, Asclerocheilus beringianus, Euzonus williamsi, Barantolla americana, Decamastus gracilis, Mediomastus capensis, and Stygocapitella subterranea are newly recorded from Washington or from Washington and British Columbia. Most of these species have not previously been reported from the cold temperate northeastern Pacific Ocean. In addition, new descriptive information is provided for some species.

Palmaria hecatensis sp. nov. is described based on material from northern British Columbia. Male gametophytes and tetrasporophytes are thick, coriaceous, flattened blades, linear to lobed in habit and arise from an extensive encrusting basal holdfast. Putative female gametophytes are microscopic multicellular discs. Palmaria hecatensis grows on rocky shores in the midintertidal to lower intertidal zones and has a known geographical distribution from Nootka Island, Vancouver Island, B.C., to Shemya Island in the Aleutian Islands, Alaska. Palmaria hecatensis is compared with other species in the genus and, in addition, another distinctive (and possibly undescribed) Palmaria species from British Columbia and Alaska is discussed, bringing the total number of Palmaria species reported in the North Pacific Ocean to six.

Betapista dekkerae, new genus and new species, is described. The generic diagnoses for Laphania and Scionides are improved after inspection of the holotypes of the type species. Eupolymnia heterobranchia (syn., E. crescentis) is redescribed. Additions to the descriptions, based on study of type material, are made for Laphania boecki (new record, Northeast Pacific), Neoamphitrite robusta (syn., Scionides dux), Neoleprea californica and N. spiralis, Pista brevibrunchiata (new record, British Columbia [B.C.], Washington [WA], Japan) and P. fratrella, and Polycirrus californicus (new record, B.C., WA, syn., P. perplexus). Other additions to the descriptions are provided for Amaeana occidentalis (new record, B.C.) and Pista cristata. Two further Pista species (one from the Skagerrak) and five Polycirrus species are charcterized but not named. Other new records are Lanassa venusta venusta (B.C.), Lysilla loveni, and Neoleprea japonica (the two latter for Northeast Pacific). Lysilla pacifica, Pista fasciata, and P. fratrella are shown not to be members of the fauna of British Columbia and Washington. Presumably, neither is Polycirrus caliendrum. New observations on the types of the Antarctic Polycirrus kerguelensis and Ereutho kerguelensis are noted.Key words: Betapista n.g., Neoleprea, new records, Northeast Pacific, Pista, Polycirrus, Scionides, Terebellidae

To understand the interior of British Columbia the reader must realize that the white man's history there is short, for Alex Mackenzie was the first white man to make his way overland to the Bella Coola Valley in 1793. Three years later, on his journey to the Pacific Ocean, he followed the Mackenzie River to Mackenzie Bay on the Beaufert Sea.

Iron Concentrations

Total and "HCl reactive" iron has been determined for particulate and soluble forms in freshwater and seawater samples along a profile extending from Hope, British Columbia, 100 miles up the Fraser River, to a station in the Northeast Pacific Ocean, 60 miles west of Cape Flattery, Washington. Complementary data were taken on salinity, dissolved oxygen, pH, and temperature. Observations covered periods of high and low river runoff from June 1962 to June 1963.Total particulate iron concentrations in the Fraser River were highest during the maximum runoff period in summer, while total soluble iron concentrations did not significantly increase at this time. Admixture of saline water with fresh water at the river mouth caused the expected abrupt decrease in particulate iron below the upper 2 m.Both the total particulate and total soluble iron concentrations in seawater samples decreased from the Strait of Georgia seaward through Juan de Fuca Strait out into the Pacific Ocean. In summer, the total soluble iron was higher than in winter while the total particulate iron was lower. The seasonal fluctuations of the sum of the total particulate and total soluble iron were not significant.The high amounts of the soluble forms of iron and the concurrent low particulate iron concentrations in summer may be partially explained by the assimilation of particulate iron during periods of high phytoplankton productivity, mainly by diatoms, with release of soluble forms during lysis of these organisms.The mean annual total iron discharged by the Fraser River was 1.90 × 105 kg/day, the bulk of which was immediately laid down in the river delta.There was no evident correlation of the iron distribution with that of pH, oxygen, or density, excepting in the region immediately adjacent to the mouth of the Fraser River.
