A new species of dendrochirote holothuroid from the northeast Pacific Ocean is described. Cucumaria pallida n.sp. is compared with two similar species, Cucumaria fallax Ludwig, 1874 and Cucumaria miniata (Brandt, 1835). Cucumaria pallida, previously thought to be a pale form of C. miniata, is a common subtidal species with a cream–white skin and delicate, translucent tentacles. Cucumaria pallida n.sp. is known from the Alaska–British Columbia border south to the Channel Islands, California, and from the intertidal zone to a depth of 91 m. The shape and size of the ossicles, number of stone canals, body colour, and reproductive characteristics distinguish C. pallida from other species of Cucumaria.

Five species of Pogonophora have been found in collections of benthos from depths of 200 to 2680 meters off the coast of British Columbia, Canada. They include two species already known from the Pacific, Polybrachia canadensis and Siboglinum pusillum; a new species of Lamellisabella, and a new species of Siboglinum. The fifth species is probably another new species of Siboglinum, but the specimens are not sufficiently complete for definite determination.

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

Carnivorous feeding among the Cladorhizidae (Porifera, Demospongiae, Poecilosclerida) was first documented in 1995. Since that time, 161 species have been described and are currently recognized in 9 genera. Cladorhiza is the most speciose genus with a global, deep-water distribution of 41 species. Here we describe three new Cladorhiza species of ‘crinorhiza’ form from the Northeast Pacific Ocean off California, USA, and the Gulf of California, Mexico, from depths of 2472–4100m. In total, 11 specimens were collected between 1969 and 2015. Video recordings from remotely operated vehicles yield additional information on habitat type, geographic distribution, and abundance for some of these species.

Taxonomic studies, based on biochemical and physical morphology, of the Sebastes aleutianus–S. melanostomus complex (family Scorpaenidae) resulted in the identification and description of new species, Sebastes caenaematicus, whose known range is Cape Flattery, Washington, to Cape Ommaney, Alaska. A synonymy and literature history for the complex is presented.

A New Species

A new species of sea cucumbers of the genus Lissothuria Verrill, 1867 is described. Lissothuria imbricata sp. nov. was found in the central-eastern Pacific Ocean, at 2–16 m depth living on top of rocky reefs, partially covered by algae and organic material. It is distinguished from other species of the genus by having body wall ossicles in form of short, broad towers with a slightly spiny apex, giving the dorsal area a granular appearance. The shape of the ossicles shows some similarities with L. nutriens (H.L. Clark, 1901).

The male of Metridia okhotensis (Copepoda: Calanoida) is described here for the first time. It can be separated from similar species, including M. longa, a morphologically similar species found in the Atlantic and Arctic oceans, on the basis of body size, the relative length of the first antennae, and the shape of the fifth leg. Here we describe both the fifth and sixth copepodite stages of male and female M. okhotensis, and present a tabular key to members of the genus reported from the northeast Pacific Ocean. In addition, we show that M. okhotensis is widely distributed in the protected waterways of the British Columbia coast, and at times and in some places it is numerically dominant. Particularly high numbers are found in Loughborough and Portland inlets and Douglas Channel. The size of the copepod and of its population suggest it plays an important role in the zooplankton dynamics of British Columbia nearshore waters.

A New Species

A new species of anglerfish, Chaunax nudiventer, is described on the basis of 35 specimens from the western South Pacific Ocean. It is characterized by large spots on the dorsal surface; a largely naked area on abdomen; a relatively short head and long tail, both reflected in the elongated body; slender and simple spines on body surface; numerous broad flaps on lateral side of body; and higher number of lateral line neuromasts: mainly 41–43 in lateral line proper, 4 in the upper peropercular series, and 16–17 in the pectoral series. Comments on a similar species, C. latipunctatus from the eastern South Pacific Ocean, is provided.
