Canda alsia Winston, Vieira & Woollacott, 2014: 164, figs. 15, 16 (cum syn.); Almeida et al. 2015b: 3.
Material examined. UFBA 1192, UFBA 2361–62, Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (on sponge Bubaris sp.); UFBA 1663, UFBA 2363–64, Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (on sponge Haliclona (Soestella) melana); UFBA 1670, UFBA 2365–67 Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (on sponge Tedania ignis).
Remarks. Canda alsia has erect rooted colonies with branches connected by transverse tubular kenozooids, autozooids with one inner distal spine and a narrow mushroom-shaped scutum, short curving vibracula and ooecia with single and large fenestra (Fig. 29) (Winston et al. 2014). Despite the other records of Canda from the Brazilian coast— Canda philippinensis Canu & Bassler, 1929; Canda retiformis Pourtalès, 1867 and Canda simplex Busk, 1884 (Vieira et al. 2008) —Winston et al. (2014) suggested they belong to C. alsia (see Winston et al. 2014 for more information). Some specimens of C. alsia from Brazil were found attached on cable (Winston et al. 2014). Caribbean species of Canda are commonly found in coral reefs (e.g., Winston 1984, 1986; Hughes & Jackson 1992). Here we present the first record of a Canda species associated with sponges.
Distribution. Atlantic: endemic to Brazil (Bahia, Espírito Santo and Rio de Janeiro) (Winston et al. 2014; present study).

Poricella frigorosa Winston, Vieira & Wollaccott, 2014: 186, fig. 30. Poricella mucronata: Almeida et al. 2015b: 4.
Material examined. UFBA 1585, Todos os Santos Bay, 13°00’S, 38°32’W, 3–8 m, coll. 2013 (on sponge Callyspongia sp.); UFBA 2066, UFBA 2388, Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (on sponge Myrmekioderma sp.).
Remarks. Poricella frigorosa has encrusting colonies (Fig. 34), autozooids with 3–4 orificial spines, an anchor-shaped frontal mucro, a central cluster of two or three round to oval pores, large interzooecial avicularia with a typically straight and pinched distal margin, and with a densely calcified ooecia opening above the operculum (Fig. 35) (Winston et al. 2014). Poricella frigorosa is part of the Poricella mucronata (Smitt, 1873) species complex (Winston et al. 2014). Until the description of P. frigorosa, P. mucronata and Poricella sp. were the only species recorded from the Brazilian coast (Vieira et al. 2008; Almeida et al. 2015b). Part of these specimens may also belong to P. frigorosa. No information about the substrata of the specimens reported from Brazil was given. Species of Poricella are known to encrust other bryozoans, coral skeletons, red algae, lava boulders and serpulid tubes (Tilbrook et al. 2001; Berning 2006; Dick et al. 2006; Moissette et al. 2007).
Distribution. Atlantic: endemic to Brazil (Bahia and Rio de Janeiro) (Winston et al. 2014).

Reptadeonella leilae Almeida, Souza, Sanner & Vieira, 2015c: 362, figs. 33–36, 42 (cum syn.).
Material examined. UFBA 1174, Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (on sponge Halichondria sp.).
Remarks. Reptadeonella leilae is characterized by unilaminar encrusting colonies (Fig. 36), autozooids with a tubular peristome, a circular spiramen and no avicularia (Fig. 37) (Almeida et al. 2015c). The species grows on small substrata such as calcareous nodules (Almeida et al. 2015c). Other Reptadeonella species are frequently found encrusting rocks, other bryozoans, calcareous nodules and algae, corals and shells (e.g., Marcus 1939; Soule 1961; Winston 1982b; Hayward & Ryland 1999; Tilbrook et al. 2001; Tilbrook 2006; Winston & Vieira 2013; Almeida et al. 2015c). Reptadeonella leilae was found attached to the smooth-textured sponge Halichondria sp., representing the first record of an association with sponges in the genus.
Distribution. Atlantic: endemic to Brazil (Bahia) (Almeida et al. 2015c).

Celleporaria atlantica: Winston et al. 2014: 191, figs. 33A-D, 34, 35 (cum syn.); Almeida et al. 2015b: 4.
Material examined. UFBA 1180, Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (on sponge Topsentia ophiraphidites); UFBA 1181, UFBA 2389–90, Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (on sponge Haliclona (Soestella) melana); UFBA 1188, UFBA 2391–92, Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (on sponge Bubaris sp.).
Remarks. Celleporaria atlantica was recently redescribed by Winston et al. (2014), who studied original specimens from Busk (1884). Although Busk (1884) described C. atlantica from Brazil (Bahia state) and Australia (Possession Island), Winston et al. (2014) elucidated that specimens from Possession Island truly belong to Celleporaria fusca (Busk, 1854) and thus C. atlantica is restricted to Brazilian waters. Busk (1884) found C. atlantica on seafloors composed of gravel and shells. Other species of Celleporaria are commonly found associated with corals and rocks (e.g., Winston 1986; Winston 2005).
Celleporaria atlantica has encrusting colonies, autozooids with almost rounded orifice with a shallow and wide sinus, suboral avicularium placed on a pointed umbo (Fig. 40), small leaf-shaped avicularia associated with marginal areolar pores and spatulate avicularia occurring between zooids (Fig. 41) (Winston et al. 2014). Celleporaria atlantica is often found at Bahia state forming nodular colonies attached to hard substrata such as rocks and calcareous nodules. Colonies of C. atlantica here studied are unilaminar and were encrusting the rugose sponge Bubaris sp. (Fig. 8) as well as the smooth-textured sponges Haliclona (Soestella) melana and Topsentia ophiraphidites.
Distribution. Atlantic: endemic to Brazil (Bahia and Espírito Santo) (Winston et al. 2014).

Material examined. UFBA 1587, UFBA 2394, Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (on sponge Haliclona (Soestella) melana); UFBA 1182, Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (one colony on sponge Ircinia felix).
Remarks. Stylopoma aurantiacum has encrusting colonies (Fig. 54), a keyhole-shaped orifice with distinct condyles, frontal avicularia rounded proximally and subtriangular distally (Fig. 56), large shoe-shaped interzooidal avicularia (Fig. 58) and large ooecia with crab claw-like extensions from either side of the base of the opening (Fig. 59) (Canu & Bassler 1928a; Winston et al. 2014). Winston et al. (2014) first reported S. aurantiacum since its original description, but here we first figure ooecia of S. auratiacum (Fig. 59). We found two colonies attached to the sponges Haliclona (Soestella) melana and Ircinia felix. The widely known Stylopoma spongites (Pallas, 1766) received its name owing to its association with a sponge (Tilbrook 2001), suggesting Stylopoma species might be common on that substratum.
Distribution. Atlantic: endemic to Brazil (Pernambuco and Bahia) (Winston et al. 2014).

Hippaliosina imperfecta: Winston et al. 2014: 209, fig. 44 (cum syn.); Almeida et al. 2015b: 5.
Material examined. UFBA 2065, UFBA 2395, Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (on sponge Myrmekioderma sp.).
Remarks. Hippaliosina imperfecta is characterized by having encrusting colonies (Fig. 60), more or less hexagonal zooids, oblong autozooidal orifices, and small down-curved and elongate avicularia (frequently paired) placed laterally to the orifice (Fig. 61) (Winston et al. 2014). Hippaliosina imperfecta is the only species of the genus recorded from Brazil and is also considered endemic to the area (Winston et al. 2014). Other species of Hippaliosina were already documented in association with organisms such as other bryozoans, molluscs and algae (Osburn 1952; Shier 1961; Hayward 1974; Winston 1982b, 1986). This is the first record, however, of a Hippaliosina species associated with the smooth-textured sponges Myrmekioderma sp. and Desmapsamma anchorata.
Distribution. Atlantic: endemic to Brazil (Bahia, Espírito Santo and Rio de Janeiro) (Winston et al. 2014).

Material examined. UFBA 1183, Camamu Bay, 13°53’S, 38°59’W, 18–20 m, coll. October 2012 (on sponge Spongosorites sp.).
Remarks. Calyptooecia conuma is characterized by small spot-like colonies (Fig. 72), brooding zooids without perioral tubercles, and non-brooding zooids surrounded by 4–5 conical tubercles and a single, asymmetrically placed, suboral avicularium on almost all zooids (Fig. 73) (Almeida & Souza 2014). Only two species of Calyptooecia are known worldwide (Bock 2016). Calyptooecia insidiosa Winston, 1984 is found in the Caribbean where colonies are associated with coral undersurfaces and reef caves (Winston 1984). Calyptooecia conuma commonly encrusts calcareous nodules, shells, coralline algae and sponges (Almeida & Souza 2014). We examined a small colony attached to recesses of the rugose-textured sponge Spongosorites sp. (Fig. 11).

Remarks. Triphyllozoon arcuatum has erect robust, thickly calcified, lace-like colonies (Fig. 81), autozooids with low peristome and peristomial avicularia, frontal avicularia either small and round and/or large and oval (Fig. 82), large columnar avicularia, and a globose ovicell with sutures varying from arcuate to trifoliate with a short distal limb (Fig. 83) (Almeida et al. 2015a). Triphyllozoon arcuatum was recently recorded in the Western Atlantic for the first time, being recognized as a non-indigenous species to the area (Almeida et al. 2015a). Specimens of T. arcuatum here examined were found associated with the rugose-textured sponges Tedania ignis (Fig. 12). Triphyllozoon species are frequently found associated with other invertebrates, including the demosponges Tedania ignis and Dysidea etheria, and the calcareous sponge Clathrina sp. in Bahia State (for more information see Almeida et al. 2015a).
Distribution. Indo-Pacific: South Australia, Northern Territory and Singapore. (Hayward 1999; Tilbrook & Gordon 2015). Atlantic: Brazil (Pernambuco and Bahia) (Almeida et al. 2015a).

Diagnosis. Titanoecidae are cribellate araneomorph spiders lacking tarsal trichobothria, with only a single metatarsal trichobothrium, the MAP spigots of the ALS set partially surrounded by the Pi spigot field and possessing a complex dorsal apophysis (DTA) which can be devided into a retrolateral (RLT), a median (MLT) and a prolateral (PLT) lobe on the male palpal tibia. They are distinguished from both Megadictynidae and Phyxelididae by a complex, three-lobed (not simple) DTA and in lacking paracribellar spigots on the PMS, and are further distinguished from Megadictynidae in having a divided (not entire) cribellum and from Phyxelididae in lacking any clasping modifications of the first male metatarsus (See Griswold et al. 1999; Dimitrov et al. 2017).

Glypteuthria

description: Genus Glypteuthria Strebel, 1905
Type species. Euthria meridionalis E.A. Smith, 1881 by subsequent designation of Tomlin, 1932.
This genus was also cited by Harasewych & Kantor (2004) from South Africa with three species included, G. capensis Thiele, 1925, G. solidissima Tomlin, 1932, and G. sculpturata Tomlin, 1945 (new name for G. capensis Tomlin, 1932 non Thiele, 1925).
The holotype of Glypteuthria (?) capensis Thiele, 1925 is housed at the Museum für Naturkunde, Berlin (ZMB 101552) and illustrated by Weaver & DuPont (1970: 183, pl. 78C, D). The morphology of the shell is similar to G. meridionalis, however no soft parts are known and the protoconch appears to be smooth (according to these authors) instead of showing the typical spiral pattern of this species. Weaver & DuPont (1970) included G. capensis Thiele in Fusivoluta and mentioned the confusion of Barnard (1957: 210) and later Rehder (1969: 205), who stated that G. capensis Thiele and G. sculpturata Tomlin are synonyms and they belong in Fusivoluta. In 1970, Rehder after studying a photograph of Thiele’s types, reported both species as different but again as belonging in Fusivoluta. This is true only for G. sculpturata. Kilburn et al. (2010) cited G. c a p e n s i s Thiele as part of the South African living fauna. Until the radula of this species is studied, its inclusion in Glypteuthria should be with caution. The remaining name G. solidissima with a shell with inner apertural denticles does not belong in Glypteuthria. This species was regarded as a junior synonym of Afrocominella capensis simoniana (Petit de la Saussaye, 1852) by Kilburn et al. (2010).

Meteuthria

description: Genus Meteuthria Thiele, 1912
Type species. Euthria martensi Strebel, 1905 by original designation.
Several species were included by different authors in the genus Meteuthria. Dell (1990) included “ Anomacme ” multituberculata Castellanos et al., 1987 in Meteuthria because of some similarity of the radula of his new subspecies of Meteuthria (i.e. M. multituberculata rossiana). The radula of “ A.” multituberculata is illustrated here (Figs 10 H–I) and it is very different from the types of both genera: Meteuthria (i.e. M. martensi) and Anomacme (i.e. A. smithi, Figs 10B, C).
The distinctive protoconch and the presence of a very small rachidian (not illustrated by Dell 1990: 169 fig. 296) indicate that neither “ Anomacme ” multituberculata nor the subspecies M. multituberculata rossiana are referable to either Meteuthria or Anomacme. Only two species (M. martensi and M. batialis n. sp.) are here considered as belonging to Meteuthria.

Falsimacme

description: Falsimacme new genus
Type species. Euthria Glypteuthria kobelti Strebel, 1905.
Diagnosis. Shell fusiform, small, protoconch small, 1½ whorls, smooth, spiral ornamentation of rounded threads crossed by axial varices; operculum subelliptical, nucleus subterminal; radula prosiphiine, rachidian teeth absent; laterals with 5 to 8 cusps, the cusps point posteriorly within the animal, slightly decreasing in size from the center to the sides of the radula.
Etymology. The name acknowledges the (falsa = false in Spanish) resemblance to the radulae and shell of the species Anomacme smithi Strebel. The genus is masculine.
Included species. Only F. kobelti (Strebel, 1905).
Distribution. As the type species.
Remarks. Crenatosipho Linse, 2002 resembles Falsimacme n. gen. However, the radula has a small rachidian and large curved lateral teeth, both characters absent in Falsimacme n. gen.

Meteuthria martensi Strebel. Castellanos, 1992: 20, pl. 1, fig. 7 only.
Type material. 3 syntypes from Shallow Bay, Lively Island are deposited at the Manchester Museum. One of these specimens, EE.7750, illustrated here in Figs 21 A–C, is designated as lectotype in order to preserve stability of nomenclature in agreement with ICZN article 74; and 2 others are paralectotypes, EE.7751 (Figs 21 D–F, G–I).
Description. Shell small, less than 10 mm in height, fusiform, red, brownish, bright, outside and inside, of 6 slightly convex, distinct whorls; protoconch of 2 1/2 convex whorls (Figs 21 O, P), translucent, entirely smooth, transition to teleoconch only signalled by onset of spiral ornamentation; suture impressed, somewhat channelled; aperture oval, siphonal canal deep, oblique and short; parietal callus very thin; spiral ornamentation of thick threads, 3 in the second and third whorls, 4 in the others; axial sculpture of 12 to 13 varices that develop into nodes when crossing the spiral threads.
Operculum (Fig. 22 D) thick, elliptical in shape, nucleus subterminal, attachment area with a thick rim. Radula (Figs 22 A–C) as in A. paessleri; lateral teeth have 3 cusps but the innermost less developed. Penis (Fig. 22 E) as in the other species of the genus.
Material examined. 29 spms., Ushuaia, (MACN-In 40507).
Distribution. Known from Ushuaia, Beagle Canal, Tierra del Fuego and Lively Is.
Remarks. This species was included in Argeneuthria basically because of the close similarity with radula and penis of A. paessleri despite some minor proportional variations. The shell morphology most closely resembles that of F. kobelti; however, the protoconch in F. kobelti is smaller (1.5 whorls in F. kobelti vs. 2.5 whorls in A. euthrioides). Also, in A. euthrioides the ornamentation begins with axial varices and then the spiral cords appear, while in F. kobelti three cords develop initially on the first whorls over a smooth surface and then the axial varices rise (see figures 15I –K). In addition, A. euthrioides has a shorter siphonal canal, lower spire and the nodes are more globose and rounded that those of F. kobelti.

2015 Acmaeidae gen. et sp. indet.; Hryniewicz et al. 2015a, table 1.
Diagnosis: Surface covered with thick commarginal ribs. Aperture elongated, oval. Apex slightly subcentral. Holotype: PMO 217.516, H = 1.8 mm, L = 4.1 mm, W = 3.3 mm.
Type locality and age: Seep #9, Sassenfjorden, Svalbard; late Berriasian, Early Cretaceous. Other material: Two additional specimens (one illustrated PMO 224.752) from the type locality. Description. Protoconch not preserved. Shell patelliform, elongate, oval; width is 81% of length. Apex moderately high, heavily eroded, situated slightly subcentrally; height is 43% of length. Shell exterior covered with thick concentric ribs. Radial ornament very weak, consisting of straight and faint radial riblets. Apertural margin straight in lateral view. Muscle scars not visible.
Remarks. The concept of genera in Pectinodontidae is based mainly on radular characters (Sasaki et al. 2003). A slight difference in the apex position delimits, though tenuously, the shells of Pectinodonta and Bathyacmaea. The Sassenfjorden limpet has a slightly subcentral apex, so we decided to place it, though with hesitation, in Pectinodonta. The most similar species to? Pectinodonta borealis sp. nov. is Pectinodonta waitemata Marshall, 1985, from Miocene flysch deposits with plant and wood material from New Zealand. Pectinodonta waitemata also has strong concentric ridges and faint radial ornament; however, its apex is positioned much more eccentrically. The Oligocene Pectinodonta palaeoxylodia Lindberg & Hedegaard, 1996 from a wood-fall in Washington State, USA differs in having a stronger radial ornament than commarginal (Lindberg & Hedegaard 1996).
Distribution. Type locality only.
Etymology. Northern in Latin.

Remarks. The taxon Eucycloidea was described by Huddleston (1888) as a subgenus of Purpurina (family Purpurinidae) and subsequently transferred by Gründel (1973) to the mathildids. Subsequently Gründel (1997) investigated d’Orbigny’s (1850) type species material and re-interpreted the genus as an eucyclid. This attribution has been accepted by subsequent authors (e.g. Bandel 2010).

description: Hokkaidoconcha sp.
(Fig. 5I –M)
2015 Hokkaidoconchidae gen. et sp. indet.; Hryniewicz et al. 2015a, table 1.
Description. Cerithioid shell with opisthocline to slightly opisthocyrt axial ribs and fine numerous spiral riblets. Whorl flanks are weakly inflated and the suture weakly incised. Protoconch and aperture not preserved.
Material and occurrence: Three specimens from seep #12, Sassenfjorden, Svalbard; late Berriasian (Early Cretaceous). All illustrated: PMO 217.507, PMO 217.509, PMO 217.511b.
Remarks. Hokkaidoconcha sp. is represented by three incompletely preserved juvenile specimens, so several pertinent shell characters could not be observed, and this is the reason why we decided to leave this species in open nomenclature. Our Hokkaidoconcha sp. from Svalbard is most similar to juveniles of the Cenomanian H. tanabei from Japan (Kaim et al. 2008b). The latter species, however, grows to a relatively large size and its ornament changes with ontogeny. Changes in ontogeny could not be observed in Hokkaidoconcha sp. from Svalbard due to the fragmentary preservation. Another similar species is H. occidentalis (Stanton, 1895) from the Late Jurassic– Early Cretaceous of California (Kiel et al. 2008; Kaim et al. 2014) which seems, however, to have a much weaker developed spiral ornamentation and stronger axial ribs. Hokkaidoconcha hignalli Kaim & Kelly, 2009 from the Tithonian (Late Jurassic) Gateway Pass seep on Alexander Island, Antarctica, loses the ornamentation during ontogeny and may thus actually belong to the genus Hudlestoniella (see below). Superficially, Hokkaidoconcha sp. is similar to juvenile specimens of Hudlestoniella hammeri (see below), but it differs in having stronger and persistent spiral ornament (which at the size of Hokkaidonconcha sp. already fades away in H. hammeri) and opistocline to weakly opistocyrt axial ribs, rather than strongly opistocyrt ribs as observed in H. hammeri.

description: ? Hokkaidoconcha sp.

Description. Abyssochrysoid shells ornamented with strong orthocline axial ribs which do not reach the suture adapically and with numerous spiral riblets which cross over the axial ribs. Growth lines prosocline. Whorl flanks are weakly inflated and the suture moderately incised. Protoconch and aperture not preserved.
Material and occurrence: Three specimens preserved as external moulds from seep #3 (all illustrated: PMO 224.759–761); Sassenfjorden, Svalbard; late Tithonian, Late Jurassic.
Remarks.? Hokkaidoconcha sp. is represented only by shell fragments and several features (e.g. protoconch, aperture) could not be observed in the available specimens. This is why we decided to leave this species in open nomenclature. Similar shells have been described by Sohl (1960) from the Late Cretaceous of the USA as species of Melanatria: Melanatria? cretacea Wade, 1926 and Melanatria? sp. The genus Melanatria Bowdich, 1822 is considered to be an objective synonym of Pirena Lamarck, 1822, which in turn is a synonym of Faunus Montfort, 1810 (for details see Köhler & Glaubrecht 2010). In the past, the type species of Melanatria was repeatedly wrongly cited as Buccinum flumineum Gmelin, 1791 (e.g. Sohl 1960), which is now interpreted as nomen dubium (Köhler & Glaubrecht 2010) but previously synonymized with the modern freshwater pachychilid cerithioidean Madagasikara spinosa (Lamarck, 1822). The latter species (and the entire genus Madagasikara) is endemic to Madagascar (Köhler & Glaubrecht 2010). It is therefore rather unlikely that this genus is present in the marine deposits either in the Late Jurassic of Spitsbergen or Late Cretaceous of the USA. Instead, we think that all these shells may represent an as yet undescribed genus of abyssochrysoids similar to Hokkaidoconcha. We do not attempt to describe a new genus here because of the poor preservation of the available material and we temporarily place it in Hokkaidoconcha, pending better material becoming available.
