W. Patagonia, 125 fms. [228.6 m] depth (Chile). Description. Shell medium sized, up to 22 mm in height, fusiform, of six convex whorls; protoconch (Fig. 4 F) of 2 ½ convex whorls, translucent, smooth, transition to teleoconch well defined; suture impressed, aperture oval, labrum expanded, sharp, with a small, curved subsutural slit; siphonal canal short; parietal callus very thin; axial ornamentation of about 10 to 12 varices, complete in all whorls but the last, where they vanish below middle whorl; some specimens, only with weak varices on the early whorls; spiral ornamentation of about 15 characteristic, regularly spaced striae per whorl, 30 on the last; periostracum absent (?); color typically pinkish, reddish or dark purple, inside creamy white; operculum (Fig. 4 G) brown, ovate, nucleus subterminal. Radula (Figs 4 A–C) rachiglossate, very similar to P. fuscata , but the cusps of the lateral teeth are more closely spaced in P. atrata, particularly in the juvenile specimens. Linse (2002) mentioned that the radula is also shorter. Penis (Figs 4 D, E) large, long, subrectangular, flat, generally similar to that of P. f u s c at a . Some minor differences are likely due to the reproductive stage and the reaction to critical point drying method. Material examined .

Distribution. Off Buenos Aires province to Ushuaia, Tierra del Fuego, Malvinas and Staten Is., Argentina in the Atlantic; Southern Chile, Punta Arenas, to Calbuco (41°S) in the Pacific Ocean. Remarks. This is a very variable species with a large geographic range. The main variations are in the size and number of axial varices. Also the spiral striae are sometimes worn, rendering an almost smooth pattern as seen on some of the syntypes. Cernohorsky (1977) considered Fusus scalaris Watson as a synonym of his Pareuthria powelli (new name for Fusus roseus Hombron & Jacquinot, 1854 non Anton, 1838) so he proposed no substitute name for this species despite the homonym with F. scalaris Lamarck, 1816. The type material of Watson’s species is housed at the NHMUK and is illustrated here in figures 3P– R. It was collected by the HMS CHALLENGER expedition at Station 305A (47°48'30"S, 70°47'W), which is obviously incorrect as this point lies in the center of Santa Cruz province, Argentina. It could probably be 74°W instead of 70°W, which is north of Wellington Is., Golfo de Penas, Chile. The material reported by Watson presented some differences such as its white colour, which is usual in dead specimens. Nevertheless, the shell morphology falls within the variation range of P. atrata . : Published as part of Pastorino, Guido, 2016, Revision of the genera Pareuthria Strebel, 1905, Glypteuthria Strebel, 1905 and Meteuthria Thiele, 1912 (Gastropoda: Buccinulidae) with the description of three new genera and two new species from Southwestern Atlantic waters, pp. 301-344 in Zootaxa 4179 (3) on pages 308-312, DOI: 10.11646/zootaxa.4179.3.1, http://zenodo.org/record/256431 : {"references": ["Smith, E.

Shell medium sized, up to 22 mm in height, fusiform, of six convex whorls; protoconch (Fig. 4 F) of 2 ½ convex whorls, translucent, smooth, transition to teleoconch well defined; suture impressed, aperture oval, labrum expanded, sharp, with a small, curved subsutural slit; siphonal canal short; parietal callus very thin; axial ornamentation of about 10 to 12 varices, complete in all whorls but the last, where they vanish below middle whorl; some specimens, only with weak varices on the early whorls; spiral ornamentation of about 15 characteristic, regularly spaced striae per whorl, 30 on the last; periostracum absent (?); color typically pinkish, reddish or dark purple, inside creamy white; operculum (Fig. 4 G) brown, ovate, nucleus subterminal. Radula (Figs 4 A–C) rachiglossate, very similar to P. fuscata , but the cusps of the lateral teeth are more closely spaced in P. atrata, particularly in the juvenile specimens. Linse (2002) mentioned that the radula is also shorter. Penis (Figs 4 D, E) large, long, subrectangular, flat, generally similar to that of P. f u s c at a . Some minor differences are likely due to the reproductive stage and the reaction to critical point drying method. Material examined .

Distribution. Off Buenos Aires province to Ushuaia, Tierra del Fuego, Malvinas and Staten Is., Argentina in the Atlantic; Southern Chile, Punta Arenas, to Calbuco (41°S) in the Pacific Ocean. Remarks. This is a very variable species with a large geographic range. The main variations are in the size and number of axial varices. Also the spiral striae are sometimes worn, rendering an almost smooth pattern as seen on some of the syntypes. Cernohorsky (1977) considered Fusus scalaris Watson as a synonym of his Pareuthria powelli (new name for Fusus roseus Hombron & Jacquinot, 1854 non Anton, 1838) so he proposed no substitute name for this species despite the homonym with F. scalaris Lamarck, 1816. The type material of Watson’s species is housed at the NHMUK and is illustrated here in figures 3P– R. It was collected by the HMS CHALLENGER expedition at Station 305A (47°48'30"S, 70°47'W), which is obviously incorrect as this point lies in the center of Santa Cruz province, Argentina. It could probably be 74°W instead of 70°W, which is north of Wellington Is., Golfo de Penas, Chile. The material reported by Watson presented some differences such as its white colour, which is usual in dead specimens. Nevertheless, the shell morphology falls within the variation range of P. atrata . : Published as part of Pastorino, Guido, 2016, Revision of the genera Pareuthria Strebel, 1905, Glypteuthria Strebel, 1905 and Meteuthria Thiele, 1912 (Gastropoda: Buccinulidae) with the description of three new genera and two new species from Southwestern Atlantic waters, pp. 301-344 in Zootaxa 4179 (3) on pages 308-312, DOI: 10.11646/zootaxa.4179.3.1, http://zenodo.org/record/256431 : {"references": ["Smith, E.
