“…On the other hand, acteonids also lack dedicated studies in the Western Atlantic, where few works have been published (Rehder 1939, Marcus 1972, Cunha 2011, Zelaya et al 2011. Interestingly, recent studies have revealed new genera (Bouchet 1975, Salvador andCunha 2016) and species (Smriglio and Mariottini 1996, Valdés 2008, Cunha and Simone 2018 from around the world.…”

ActeonsemicingulatusDall, 1927, previously known only by its original description is reassigned to the Pyramidellidae, inOndina, based on the collecting of several new specimens along the coast of Brazil, in the same bathymetry as the type locality. Its shell shape variation is discussed and Odostomia (Evalea) ryclea Dall, 1927 is considered a synonymy. Other Western Atlantic species, previously allocated to other genera are transferred toOndina:AclisstriataVerrill, 1880, Odostomia (Iolaea) hendersoni Bartsch, 1909,EvaleastockiDe Jong & Coomans, 1988 and Odostomia (Evalea) emeryi Bartsch, 1955 based on conchlogical comparison to the revison by Høisæter (2014), from Northeastern Atlantic. The genusEvaleais considered to be absent in the Atlantic Ocean.

“…Brasil-Petrobras started petroleum exploration in depths around 2,000 m. It is unknown how those exploratory activities affect the local fauna and the environment. Previous reports on the impact of commercial activities, mandatory under Brazilian laws, rarely deal with mollusks, and if they are included, mostly wide-ranged species are treated (e.g., Amaral et al 2003;Larrazábal & Oliveira 2003;Simone & Cunha 2003;Absalão et al 2005;Cunha 2011). As demonstrated here, the alleged presence of a wide-ranging fauna is challenged.…”

The Fissurellidae collected by the Marion-Dufresne Expedition, as well as other regional expeditions to SE Brazil are examined taxonomically, treating 21 species, of which 20 are new. The following new species are described (order according to depth range; species marked with * are from expeditions other than MD55): Cornisepta uirapa (790-940 m), Cornisepta arrepiata (295-1,050 m), Cornisepta aninga (295-1,050 m), Cranopsis hycavis (637 m), Cranopsis nymphalis (295 m), Cranopsis enigmatica (790-940 m), Cranopsis cearensis* (250 m), Cranopsis apostrema (110-940 m), Cranopsis alaris (250-450 m), Cranopsis canopa* (250 m), Cranopsis columbaris* (250 m), Emarginula suspira (54-940 m), Emarginula icosisculpta (10-12 m), Manganesepta atiaia (950-1,570 m), Profundisepta denudata* (3,000 m), Puncturella volcano (607-620 m), Rimula leptarcis (85-105 m), Zeidora pussa (607-940 m), Zeidora crepidula (790-940 m), Hemimarginula hemitoma (1-105 m). Diodora mirifica Métivier, 1972 (10-12 m), common in Brazilian oceanic islands, is the only fissurellid species previously known from that area. The genera Cornisepta, Cranopsis, Manganesepta, Profundisepta, Zeidora, and Hemimarginula are reported for the first time from Brazil. Emarginula suspira is named for material that has been misidentified as E. tuberculosa, a Miocene Mediterranean fossil.

“…This paper deals with samples from surveys conducted at Canopus Bank, off Ceará, northeastern Brazil. As a result of these surveys, numerous new gastropod species have been revealed (Cunha, 2005;Costa & Simone, 2005;Simone & Abbate, 2005;Simone, 2006;Cunha, 2011). The present paper aims to describe a new species of Nassarius from that locality.…”

Nassarius levis sp. nov. is described from Canopus Bank, off Ceará, Northeast Brazil, based on shell morphology. It differs from other Brazilian species of the genus in having a more elongate shell, with a weakly developed parietal shield and a notably smooth surface. This last trait has not yet been described among the Western Atlantic Nassarius, but it is common to other congeners from the Eastern Atlantic, such as Nassarius elatus (Gould, 1845) and the Indo-Pacific, such as Nassarius excellens (Kuroda & Habe, 1961).
