Material examined 1 spm, MBM300236 , Nansha Islands , 104º 52´E, 7º 24´N, CN SSVIIIB 8­16, 44 m depth, muddy sand, AT, Jun. 9, 1990 .

Diagnosis Shell of medium size, 55.5 mm in height, elongated and narrowly fusiform, very slim, with a long and straight siphonal canal. Teleoconch of 11–12 whorls, protoconch broken; spire slightly taller than the height of the aperture plus canal; sculpture of the spire whorls consisting of a subsutural sharp spiral cord, followed by a deeply excavated area between the subsutural cord and the terraced sinus cord, with 3–4 fine spiral threads in the concave area. Next comes the sharply terraced sinus cord and the prominent sharply peripheral carina. Below this is a relatively strong spiral cord and a deeply concave area with two additional spiral threads in it. The prominent peripheral carina is at the middle of the whorl. Shell also with dense axial lamellate threads. Aperture shorter than the spire, outer lip thin; siphonal canal long and straight. Colour cream white, finely speckled with light brown, but the brown speckles not connected vertically, on the subsutural cord the brown speckles are regularly spaced while those on the body whorl are sparse, inner part of outer lip white.

Habitat Muddy sand, 44 m depth.

Range Nansha Islands; Philippines.

Remarks This species usually was mistaken as Turris grandis ( Gray, 1834) in most of the published papers until Vera­Pelez J.L., et al (2000) clearly distinguished the two species.
