A New Species

We resolve taxonomic confusion regarding brooding sea anemones in the genusEpiactisVerrill 1869a in the North Pacific Ocean based on newly collected material from Hokkaido (Japan), Haida Gwaii (British Columbia, Canada), and Kodiak and Adak Islands (Alaska, USA), and museum specimens collected from the Kurile Islands (Russia), Alaska, British Columbia, Oregon (USA), and California (USA). We find that the internally brooding individuals identified by Hand & Dunn (1974) asCnidopus ritteri(Torrey, 1902) and placed in the genusEpiactisby Fautin & Chia (1986) belong to a new species which we describe and nameEpiactis handisp. nov.Epiactis handiandE. ritterican be differentiated by morphological and behavioural features including ornamentation and structure of the column and mode of brooding offspring. To highlight and clarify these differences, we redescribeE. ritteribased on specimens from Alaska. We provide the first account of external brooding inE. ritteri, which necessitates a clarification of the differences betweenE. ritteriand another externally brooding species from the North Pacific,E. japonicaVerrill, 1869b.Epiactis ritteriandE. japonicadiffer in sex allocation, ornamentation of the column and details of external brooding: members ofE. ritteriare gonochoric with a smooth column and brood groove which tightly closes, whereas those ofE. japonicaare hermaphroditic and have mid-column spherules.

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.

A New Species

A new species of Geodia is described from the North Pacific, collected in the summer of 2012 in the western Aleutian Islands. Geodia starki sp. nov. differs from all known species of Geodia by the possession of two categories of sterrasters and exceptionally large megascleres. The new species is compared with congeners of the North Pacific Ocean, Bering Sea, Arctic and the North Atlantic Oceans.

Annual mean body lengths of adult sockeye salmon (Oncorhynchus nerka) covary systematically from year to year in major northern and central British Columbia stocks (Nass River, Skeena River, and Rivers Inlet). These positive correlations are greatest between sexes within rivers, followed by age-classes among rivers. A common factor or factors affecting sockeye length in the North Pacific Ocean is suggested. The mean length of age 1.3 sockeye salmon but not age 1.2 sockeye caught annually in these B.C. fisheries was negatively correlated with the magnitude of Bristol Bay (western Alaska) sockeye catches. During the spring of maturation, age 1.3 sockeye from these B.C. stocks were further from their natal streams, and likely subject to more intense competition with Bristol Bay sockeye than age 1.2 sockeye. The pattern of annual marine growth measured from Skeena River sockeye scales collected during the 1960s provides additional evidence that the length of age 1.3 sockeye was related to Bristol Bay sockeye abundance in the year of maturation. No such correlation was evident in scales collected from age 1.2 sockeye. These results suggest that sockeye populations have more systematic distributions in the North Pacific Ocean than has been previously reported.

Unusual Type

Descriptions are given of two specimens of an unusual type of gonatid squid taken from the North Pacific Ocean. A discussion is made of their relationship to two existing genera, Gonatus and Berryteuthis, of the family Gonatidae, and a note is included on a North Pacific gonatid larva that may be a related earlier stage of these two specimens. Because of their size and condition, neither a new genus nor a new species is declared; however, on the basis of these records, it is suggested that there is a need for a redefinition of the genera of the family Gonatidae.

A New Species

A new species of the rare caridean genus Bresilia Calman, 1896, B. gibbosa, is described and illustrated on the basis of one ovigerous female and one male specimens collected from a shallow water marine cave in Okinawa Island, Ryukyu Islands, Japan. The new species is morphologically similar to B. antipodarum Bruce, 1990, B. briankensleyi Bruce, 2005, B. plumifera Bruce, 1990 and B. saldanhai Calado, Chevaldonné & dos Santos, 2004 in the strongly produced third abdominal tergite, the presence of a long epistomal process, and the presence of an exopodal flagellum on the first maxilliped, but is easily distinguished from all these allied species by the possession of movable spines in the dorsal rostral series and the angular, instead of spinose, pterygostomial margin of the carapace. This new species is the first representative of Bresiliidae from the North Pacific Ocean.
