This paper provides descriptions of Calcigorgia gorgonians collected from the Sea of Okhotsk and shores of the Kurile Islands between 3 Aug. 1984 and 20 Aug. 1987. New species described are the deep-water gorgonians Calcigorgia matua sp. nov. and C. simushiri sp. nov., belonging to the temperate fauna of the North Pacific hemisphere. Specimens belonging to all species of the genus were examined and the distinctive characters for each one are provided and summarized in a table. A modified diagnosis of the genus is proposed. The finding of a previously undescribed species emphasizes the need of further surveys, particularly in shelf and deeper waters, in order to improve our knowledge of this neglected fauna in Far East seas.

Two new species of Cumella (Cumacea: Nannastacidae), C. oculata and C. alaskensis are described from shallow Alaskan rocky shores. The new species C. oculata can be distinguished from other North Pacific Cumella by the combination of a large eye lobe, no spines dorsally on the carapace, and carapace without large tubercles. The new species C. alaskensis can be distinguished from the other North Pacific Cumella by the 5 spines distributed unequally on the dorsal crest.

Two new species, Anonyx dalli and A. shoemakeri, closely allied to Anonyx validus Gurjanova are described. This group of three species is unique within the genus Anonyx in having short, broad, and poorly armed second uropods and an angular lower posterior margin on the side plate of peraeopod 4. These species are medium sized and confined to the North Pacific Ocean.

Thirteen species of the Anonyx nugax group (uropod 2 partially constricted) are listed for the North Pacific and adjacent Arctic ocean. Two new species, Anonyx beringi and Anonyx barrowensis are described; A. pacificus Gurjanova, A. anivae Gurjanova, A. comecrudus Barnard, and A. epistomicus Kudrjaschov are redescribed; and the status of the other species is reconsidered and commented upon. Only four of these species, nugax, sarsi, lilljeborgi, and debruyni, have circumpolar distributions, with the other nine confined to the North Pacific region or to it and adjacent seas.

Two new species of Chondrocladia are described from the deep Pacific, off New Zealand and South Australia. These presumably carnivorous sponges are characterized by the presence of a sheath of special spicules along the stalk, for which the new term ‘trochirhabd’ is coined. Similar spicules were known from fossil strata of the Early Jurassic, suggesting that Cladorhizidae were already present in the Mesozoic. The arrangement of the trochirhabds along the stalk is similar to that described in the genus Meliiderma, which has been synonymized with Chondrocladia. We propose here the revival of Meliiderma as a subgenus of Chondrocladia, for Chondrocladia stipitata Ridley & Dendy, 1887, from the subantarctic Indian Ocean, C. occulta (Lehnert et al., 2006), described from the North Pacific as a species of Latrunculia, and for C. turbiformis sp.nov. and C. tasmaniensis sp.nov. from New Zealand’s Chatham Rise and several Tasmanian seamounts, respectively, described herein.

This paper provides descriptions of two new species of Calcigorgia gorgonians collected from the Sea of Okhotsk between 1973 and 2008. The new species are Calcigorgia herba sp. nov. and С. lukini sp. nov., belonging to the deep-water coral fauna of the temperate Northern Pacific. The taxonomy structure of the genus is reviewed and a comparative table is provided for all known species of Calcigorgia. The following taxonomic changes are made: the diagnosis of the genus was corrected from that given in Matsumoto et al. (2019); synonymization of C. simushiri Dautova, 2018 with C. spiculifera Broch, 1935 and inclusion of additional specimens in C. japonica Dautova, 2007 (both performed by Matsumoto et al. 2019) are assumed erroneous. The finding of previously undescribed species emphasizes the need for further surveys, particularly in deeper waters, to improve knowledge of the Octocorallia fauna in Far East seas. The distribution of Calcigorgia (Octocorallia, Acanthogorgiidae) is reviewed and presented based on field and collection studies published since 1935 as well as miscellaneous data from previous literature.
