New Scissurellidae and Anatomidae from the geographic and political Americas are described, with many long-standing misidentifications being corrected, and some comparisons to described species complementing the contribution. Sinezona kayae n. sp., previously mis-identified as the South African Sin. insignis, and Sin. hawaiiensis n. sp. without a selenizone, are described from Hawaii. Sinezona carolarum n. sp. is added to the Panamic province with a more depressed shell than the more common Sin. rimuloides (Carpenter, 1865), and a proportionally shorter selenizone. Coronadoa demisispira n. sp. from the Panamic and northeastern Pacific provinces is the third species in the genus, living sympatrically in the southern range of C. simonsae Bartsch, 1946. The new species is characterized by a shell with lower profile and a wider umbilicus. Anatoma alternatisculpta n. sp. from the Caribbean is most similar to A. proxima (Dall, 1927), but has conspicuously different sculpture on shoulder and base. Anatoma plicatazona n. sp. from the Caribbean has markedly upturned keels of the selenizone. Anatoma disciformis (Golikov & Sirenko, 1980) is reported from Alaska and illustrated for the first time by SEM. Thieleella kelseyi (Dall, 1905) is resurrected for what has previously been misidentified as the European Anatoma crispata (Fleming, 1828) in the northeastern Pacific, with a neotype designated, as the holotype is missing. Thieleella peruviana n. sp. from Peru is similar to T. kelseyi but has a taller shell and differs in the morphology of lateral tooth 5 of the radula. Thieleella bathypacifica n. sp. from the Panamic province is a deep-water species (2500 m), and known from a single specimen only. The species shows a marked angulation on teleoconch I at the spiral cord in the position of the selenizone; additionally it has a radula with marginal teeth showing a distinct posterior food groove. The bodies of two species (T. kelseyi, T. peruviana) were examined by SEM. An accessory cephalic tentacle between the anterior most epipodial tentacle and the eye stalk was encountered. The epipodial sense organ is recognized for the first time in Anatomidae, and the presence of bursicles on the gill is confirmed.

The genus Opaliopsis from Brazil is revised based on three deep-water species. Opaliopsis atlantis (Clench & Turner, 1952) is confirmed as occurring in north-eastern and south-eastern localities. Opaliopsis opalina (Dall, 1927) is reported for the first time in the south-western Atlantic. A new species, Opaliopsis cearense, is described from the north-eastern Brazilian coast, and is distinguished by its large number of fine spiral cords per teleoconch whorl.

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.

A Small collection of fossils from the Bokkeveld Beds has recently been sent to me for identification by the South African Museum, and some of them have been generously presented to the Sedgwick Museum. Amongst this material it is interesting to find some genera not previously recorded from the Cape and some new species. The majority of the specimens are in the condition of internal casts, and hence present especial difficulties in their determination, so that in a few cases some uncertainty must remain as to the generic position of the fossils. However, I am able to record for the first time from these beds the occurrence of the well-known lamellibranchiate genus Buchiola, and of a shell which may be identified with Nyussa arguta, Hall, of the North American Devonian. The genus Buchiola occurs in argillaceous nodules from the Zwartberg Pass crowded with individuals of the species which I have named B. subpalmata and with a few examples of an undetermined species. No other associated fossils can be recognised in these nodules, but I am informed that an abundant fauna is found in the beds at this locality.

A New Species

The present study focuses on shrimps belonging to the genus Lysmata Risso, 1816, collected from Madagascar during the Atimo Vatae expedition carried out in 2010. Lysmata malagasy sp. nov. is a new species belonging to the clade named “long accessory ramous” or “cosmopolitan” in previous phylogenetic studies. The new species can be distinguished from the only two other representatives of this group in the Indo-west Pacific, L. ternatensis De Man, 1902, and L. trisetacea (Heller, 1861), by the accessory ramus of the lateral antennular flagellum consisting of four elongated articles. Lysmata lipkei Okuno & Fiedler, 2010 is reported here from Madagascar with a remarkable extension of its known range after its original description from Japan. This species has also been reported from Singapore and, as alien species, from Brazil. Lastly, L. kuekenthali De Man, 1902 known from numerous localities in the Indo-West Pacific biogeographic area, is reported for the first time from Madagascar. Results of the present morphological and molecular analyses suggest that L. hochi Baeza & Anker, 2008 from the Caribbean Sea is a synonym of the Indo-West Pacific L. kuekenthali, and thus the latter species is alien in the western Atlantic.

Three new species of fangblennies are described from Indonesia. Meiacanthus abruptus is described based on two specimens, 31.4–36.6 mm SL, from Komodo Island and color photographs of others from Bali. The combination of a white or yellow body color and a single dark mid-lateral stripe that is bluntly rounded at its terminus on the caudal-fin base distinguishes it from other single striped species. This new species closely resembles the allopatric M. vicinus, which has the mid-lateral stripe extending farther onto the caudal fin and tapering to a point. Meiacanthus erdmanni is described from the only known specimen, 35.8 mm SL, photographed and collected in 65–70 m in Cenderawasih Bay, western New Guinea. One of the deepest known species of Meiacanthus, it has two dark mid-lateral stripes and differs from other doublestriped species in having a series of dark blotches on the base of the dorsal fin and only 24 segmented dorsal-fin rays. Meiacanthus cyanopterus, another deep-water species, is described from seven specimens, 19.8–45.3 mm SL, collected in 40–65 m at three sites in Alor Strait. In life this species has a dorsal fin with a blue-violet stripe bordered above by a wide black stripe. An identification key is provided for all the striped species of Meiacanthus, including at least one additional undescribed species previously confused with M. abditus. Color photographs of other Meiacanthus species and some new distributional records are also given.

A new genus and species in the caridean shrimp family Palaemonidae is described based on three type specimens collected at a depth range of 208–385 m off Guadeloupe, French Antilles. Zoukaris festivus gen. et sp. nov. shares many characters with several western Atlantic deep-water species currently assigned to Periclimenes Costa, 1844, as well as with the monotypic western Atlantic genus Diapontonia Bruce, 1986 and the Indo-West Pacific genus Echinopericlimenes Marin & Chan, 2014. Zoukaris gen. nov. can be separated from all of them by a unique combination of morphological features, especially the configuration of the dactylus of the ambulatory pereiopods. In addition, Periclimenes milleri Bruce, 1986 is recorded from the French Antilles based on a single specimen, also from Guadeloupe; its colour pattern is illustrated for the first time.

Four deep-water species of stalked barnacles were collected by the manned submersibles Jiaolong and Shenhaiyongshi during recent expeditions. Trianguloscalpellum regium (Wyville-Thomson, 1873), collected from the Mariana Trench at a depth of 5,462 m, represents a new distribution record. Glyptelasma gigas (Annandale, 1916), Poecilasma litum Pilsbry, 1907 and Poecilasma obliqua Hoek, 1907, collected from the South China Sea, are recorded for the first time from a mud volcano environment. Detailed photographs of these four species are presented and their partial sequences of 16S rRNA and mt COI genes are provided.

Two new species of Brazilian Psychoda Latreille are described, and Psychoda alternata Say and P. zetoscota Quate are recorded for the first time from Brazil. Psychoda divaricata Duckhouse, already described from southern Brazil, was recorded in the northeastern part of that country, as well as in the eastern Amazon region. The supraspecific classification proposed for the species of Psychoda according to Quate (= Psychodini of Jeñek) are discussed. A new classification is suggested that considers only one genus, Psychoda, divided into 12 subgenera: subgenus Psychoda Latreille, subgenus Copropsychoda Vaillant, subgenus Falsologima Jeñek & Harten, subgenus Psychodula Jeñek, subgenus Psychomora Jeñek, subgenus Psychana Jeñek & Harten, subgenus Logima Eaton, subgenus Tinearia Schellenberg, subgenus Chodopsycha Jeñek, subgenus Ypsydocha Jeñek, subgenus Psychodocha Jeñek, and subgenus Psycha Jeñek. A list of the Psychoda species from Latin America and the Caribbean region is presented.

A new species of sponge-associated pontoniine shrimp from the Belizean Barrier Reef in the Caribbean Sea is described and illustrated, and its systematic position is discussed. The single specimen available is incomplete, lacking the major second pereiopod. A comb-like arrangement of the cutting edges on the first pereiopod fingers is unique within the genus. A very short carpocerite and a strongly reduced incisor process on the mandible are among other features which are rare in other Periclimenaeus species.
