Diagnosis. Shell large (up to 63.5 mm, largest of the genus), subquadrangular, solid; protoconch always visible, never covered by callus; anterior columellar callus very thick; shell dirty pinkish, with axial irregular clear or dark lines, spire and fasciolar band brown-ocher; live animals with foot and siphon dark-pink.
Description. Shell large, subquadrangular, thick, smooth, polished (thickness ~ 1 mm); protoconch of 1 3/4 translucent whorls, transition to teleoconch indistinct; suture channeled with 5 1/4 whorls; columellar callus very thick, uniform, covering the suture and part of the spire in large specimens; aperture elongated, wide, slightly less than 5/6 of total shell length; outer lip smooth, thin, straight; posterior part of columella slightly convex and smooth with 6–11 anterior oblique folds, externally to those folds, 2 or 3 pronounced folds parallel to columellar edge; fasciolar band well defined, brown-ocher with axial bands; posterior groove deep; siphonal channel deep (Figure 4). Shell ultrastructure composed of three layers: more than half of the thickness is in the middle layer (of crossedlamellar crystals of aragonite), and outer layer (of amorphous calcite) and innermost layer (of prismatic crystals of aragonite) are thinner (Figure 5 E).
Radula rachiglossate (Figure 5 A), rachidian teeth tricuspid with the central cusp smaller, a small denticle usually present on each side of the lateral rachidian cusps (Figure 5 B). Lateral teeth C shape, with quadrangular base.
Living specimens with pink color around and on the sole of the foot and siphon. Penis muscular, elongated (Figure 5 C), tapering with a tip slightly sharpened, laterally flattened with a straight spermatic groove open all along. Siphon large, the distal tip with numerous branched papillae of two orders (Figure 5 D).
Geographic distribution. From Sumbauma (12°15’S; 37°47’W), Bahia state, Brazil to Puerto Lobos (42° 00’S; 65°04’W), San Matías Gulf, Chubut province, Argentina in 0–53 m depth.
Type material. [Porphyria urceus] was not found (see remarks); [Voluta pinguis] two probable syntypes, NHMUK 506 from the collection of the Reverend Mordaunt Cracherode (Figure 4 I), who is known to have exchanged shells with Joseph Banks, Captain Cook and the Duchess of Portland, among others (K. Way pers comm.); [Oliva brasiliensis] material is apparently lost. One specimen from the Zoological Institution (Saint Petersburg, Russia) matches the illustrated in fig. 1368, pl. 147 of Chemnitz (1788) (Figures 4 E–F) however there is no clear indication on this specimen to assure the status (Sirenko, pers. comm.).
Type locality. Voluta pinguis, Oliva brasiliensis, and Porphyria urceus all described from “ Brazil ”.

Remarks. The type material of Porphyria urceus Röding, 1789 was not found despite the cited existence of five specimens. Nevertheless it was described referring to Chemnitz’s Oliva brasiliensis (1788 pl. 147, figs. 1367– 8, rejected work according to Direction 1 ICZN, 1961). According to the ICZN art. 72.4.1 Chemnitz’ illustration is part of the syntypes of P. urceus leaving no doubts about the synonymy. Röding (1798) also cited Gmelin’s Voluta oliva (1791), which is in fact, the type species of the genus Oliva, according to Olsson & Dance (1966). Finally, he mentioned figures 1 and 2 of the plate 4 of Kammerer (1786). Plate 4 of this work represents only one figure, a bivalve, moreover none of the other plates of this book illustrates Olivancillaria species.
The syntypes of Voluta pinguis Solander, 1786 housed at NHMUK are clearly conspecific as reported by Dillwyn (1817). However, Rehder (1967) ruled out this name from the valid species of the Portland Catalogue. This was already commented by Burch & Burch (1964).
