DESCRIPTION: Shell narrowly fusiform (b/l 0.26–0.29, a/l 0.46–0.49), with subulate, orthoconoid spire; siphonal canal long (longer than rest of aperture), narrow, slightly recurved, whorls weakly convex, suture very shallow; anal sinus moderately deep, narrow, parallel-sided.

Sculptured by narrow, angular spiral cords, without intermediary threads. Subsutural cord low, bearing a simple angular cord; sulcus deep, anteriorly forming a notch-like recess, bordered by a thin crenulated flange. Sinus cord angular on spire whorls, flattening behind lip, followed anteriorly by a relatively wide interval, containing a thin, wavy intermediary thread, base of spire whorls with 4 spiral cords, the upper one peripheral. Base with ca 8 angular spiral cords, becoming progressively weaker anteriorly, plus 9 coarse, more rounded ones on rostrum. Collabral threads coarse and lamellose, particularly on later part of last whorl.

Pale violet, crest of spiral cords with a reddish-brown line, protoconch and inner lip also violet.

Protoconch conical, of ca 3 whorls, last one with opisthocline axial riblets. Attains 49.4 mm.

DISTRIBUTION: Bohol Sea, Philippines, in ca 250– 300 m.

TYPES: Holotype MNCN 15.05/39978 (pl. 25, figs C–D) , paratypes in private hands .
