Type locality: BRAZIL. Rio Grande do Sul ; off Chui, ~ 34°30 ′ S, 51°43 ′ W, 800-1,000 m [o.t., boat Kinpo Maw 58 col, 01.iv.2003].

Etymology: The specific epithet is a junction of Greek name notos, meaning south, with Latin word mare, meaning sea. An allusion to the South Atlantic occurrence of the species.

Diagnosis: Shell ~ 40 mm. Spire angle of ~40-45°. Sculpture of relatively uniform, spiral aligned pins. Carinate whorls region with inferior side concave. First spire whorls with wide carina turned superiorly. Carina periphery with aligned series of crowded small spines strongly turned superiorly, relatively uneven in size. Spiral central cord in superior area of carina large; larger spiral cord in middle of last whorl weakly developed.

Description: Shell ( Fig. 2 View Figure 2 ) about 40 mm; ~3 times longer than wide; spire angle ~40-45°. Walls thick. Growth uniformly increasing.Spire ~48% of total length;suture deep marked. Protoconch unknown (eroded). Whorls strongly carinate, forming profile angulation of 35-40°. Carina periphery with single series of aligned small spines, strongly turned upwards since first whorls, ~ 60 in penultimate whorl;each spine closely located with its neighbor spines; spines size slightly irregular, sometimes even fused with each other ( Figs. 2E, H View Figure 2 ). Sculpture of outer half of area superior to carina and entire area inferior to carina as delicate, relatively uniform pins organized in spiral lines, with also certain axial alignment; 3-4 spiral lines flanking carina in its superior area ( Figs. 2A, I View Figure 2 ), ~15 spiral lines in inferior area, being gradually narrower towards inferior ( Figs.2B, F,H View Figure 2 ). Middle larger middle spiral cord both in superior and inferior areas form carina; superior spiral cord large, constituted of successive wounded scales with ~ ⅓ carina spines’ size ( Figs. 2D, I, J View Figure 2 ), located slightly close to periphery than to suture; inferior cord only seen in body whorl as weakly larger middle spiral cord ( Figs. 2C, E, F, I View Figure 2 ). Area superior to carina between middle larger cord and suture almost smooth, possessing successive anterior-directed concavities as growth lines of previous anal notches ( Figs. 2D, I, J View Figure 2 ). Body whorl sculpture similar to penultimate whorl, ~25 spiral cords formed of aligned pins, gradually diminishing up to interior region of body whorl; those on canal subtly larger, obliquely and divergently positioned ( Figs. 2C, H, I View Figure 2 ). Aperture triangular, angled by carina, slightly longer than wide; superior region with wide, rounded anal notch ( Fig. 2J View Figure 2 ); inferior region simply opened to canal, lacking folds; weak outer concavity preceding canal ( Figs. 2A View Figure 2 , E-G). Inner apertural surface smooth ( Figs. 2A View Figure 2 , E-G). Canal simple, straight, with ~60% of spire length, prolonging shell length ~30% forwards.
