Paralomis makarovi n. sp. (Figs 3, 4) Material examined. Bering Sea: Bowers Bank, 54 ° 30 ’N, 179 ° 17 ’E, Albatross station 4772, 4.06. 1906, 629 m: male holotype, CL 23.8 mm; 3 male paratypes, CL 15–25 mm; 3 female paratypes. CL 12–23 mm (all USNM 1122582). Etymology. This new species is named after V.V. Makarov, the author of an influential 1938 monograph on lithodid biogeography. Description of the holotype. Carapace pear-shaped; rounded posteriorly, and longer than wide. Dorsal surface covered uniformly by conical spines, each with band of long setae half-way along length (Fig. 4 c) No spines dorsally or laterally notably longer than any other — no prominent spine at apex of gastric or branchial regions. Gastric region rounded and more prominent than branchial and cardiac regions, which are relatively sunken. Grooves only partially delimiting regions. Median spine of rostrum strongly curved upward, and without secondary spinules or tubercles on ventral surface; one pair of dorsal spines, and one pair of spinules at their base. Rostrum not pedunculated, such that dorsal spines do not surpass cornea in dorsal view (Figs 3 f, 4 f). Spines on the lateral margins of carapace of similar size to those on dorsal surface; spines on frontal margin subequal, much shorter than eyestalk; 10–13 spines on each side of anterolateral margin; hepatic spines barely enlarged relative to others. Ocular peduncles with long spine above cornea, and a few smaller spines along its length. Several setae above cornea (Fig. 3 c). Second peduncular segment of antenna with moderately-sized spine on outer angle, and small spine on inner angle. Antennal acicle longer than ocular peduncle, consisting of one central spine, with 2 or 3 long outer spines and 2 or 3 smaller inner spines; all spines with several setae (Fig. 3 g). Cheliped carpus with several spinules on medial face, without crest of large spines. Chelae with few spinules on dorsal border of palm, and several clusters of brush-like setae. Merus of pereiopods 2–4 with 4 or 5 ...
