A new species of deep waterEpimeriais described based on material collected in 1526–1586 m depth during the TALUD X expedition in the central Gulf of California, Mexico. It is the sixth species of this genus reported for the East Pacific.Epimeria morroneisp. nov. is morphologically similar toE. norfanziLörz, 2011 (New Zealand, 1268 m depth) andE. coraJ.L. Barnard, 1971 (off Oregon, USA, 2086 m depth).Epimeria morroneisp. nov., however, differs from these two species by a combination of several characters, including: vestigial eyes; multidentate mandibular lacinia mobilis; a distinct setae arrangement in palm and dactylus of gnathopods 1–2; the shape and relative size of coxae 1–5; and the shape of the telson.

Among the Brachyura from the Kermadec Islands in the invertebrate collection of the National Institute of Water and Atmospheric Research, Wellington, New Zealand (NIWA), are two specimens representing two deep-water species previously not known from the region. Both specimens were collected at the same station, together with the paratypes of the parthenopid crab, Garthambrus tani Ahyong, 2008. The new records are reported below to formally document their occurrence at the Kermadec Islands, New Zealand; both also represent the first records of their respective genera from New Zealand waters.  Measurements of specimens, in millimetres, refer to carapace length (cl) and carapace width (cw).

Natatolana rekohu sp. nov. from the Chatham Rise, off southeastern New Zealand is described and figured. Natatolana rekohu was collected at a depth of 2799 metres, close to the greatest recorded depth for this genus. The species is a scavenger, and was feeding on dead fish in a sediment trap. Natatolana rekohu is characterised by: reduced eyes; strongly indented anterior margin of the head; pentagonal frontal lamina, with weakly convex lateral margins; pleonites 1 and 2 not produced, 3 weakly and pleonite 4 rounded; pereopods 1 and 2 usually with 5 or 6 setae on the propodal palm. In males the large flat and widely separated penes and the strongly curved, wide and terminally toothed appendix masculina are additional diagnostic characters. As in most Natatolana the numbers of robust setae on the margins of the uropodal rami and pleotelson are also important in making a correct identification.

Two species of Serolidae, Caecoserolis carinata sp. nov. and Caecoserolis bicolor sp. nov. are described from northern New Zealand waters, the first record of the genus from New Zealand. A third species, a juvenile is recorded as Caecoserolis sp. All are deep-water species. C. carinata can be identified by the median row of prominent tubercles, and was collected from the southern New Caledonia Trough, Tasman Sea at depths of 2930–3184 m; C. bicolor has paired nodules on the head linked by a V-shaped ridge, a broad body, widest at pereonites 3 and 4, and occurs off Hawkes Bay, off eastern North Island, at depths of 2119–2337 m.

Abstract The Infraorder Astacidea comprises four superfamilies of decapod crustaceans: the freshwater Astacoidea and Parastacoidea and the marine Enoplometopoidea and Nephropoidea. The gill morphology of four species of crayfishes belonging to Astacoidea and Parastacoidea, two coral reef species of Enoplometopoidea, and 2 deep-water species of Nephropoidea are described and illustrated for comparisons and to determine characters characteristic to members of the family Parastacidae (Parastacoidea) from New Guinea. Morphology of the arthrobranchs and pleurobranchs were similar among all species, having a single stem with filament, but podobranchs of the parastacoideans differed from those of Astacoidea, being corrugated and tubular and having filaments. The astacoidean P. virginalis had a plate-like lamella with filament. The two nephropoid and two enoplometopoid species were similar to each other; their podobranch had a flat blade-like lamella without a filament and a shaft with a filament. The gill formulae of the New Guinea species of Cherax were the same as those of the Australian congeners, but the formula of the New Zealand Paranephrops planifronsWhite, 1842 was the same as those of the South American parastacids.

Bougainvillia aberrans n.sp. is described from Bermuda in the western North Atlantic Ocean. Specimens were collected at a depth of 150 fathoms (274 m) from the polypropylene buoy line of a crab trap. The hydroid colony of B. aberrans is erect, with a polysiphonic hydrocaulus, a smooth to somewhat wrinkled perisarc, hydranths having a maximum of about 16 tentacles, and medusa buds arising only from hydranth pedicels. Medusae liberated in the laboratory from these hydroids differ from all other known species of the genus in having a long, spindle-shaped manubrium, lacking oral tentacles, having marginal tentacles reduced to mere stubs, and being very short-lived (surviving for a few hours at most). Gonads develop in medusa buds while they are still attached to the hydroids, and gametes are shed either prior to liberation of the medusae or shortly thereafter. The eggs are surrounded by an envelope bearing nematocysts (heterotrichous microbasic euryteles). The cnidome of both hydroid and medusa stages consists of desmonemes and heterotrichous microbasic euryteles. The diagnosis of the genus Bougainvillia is modified to accommodate this new deep-water species.
