Shell small sized, moderately thick, trochoid, turrated and with 7 valutions of teleoconch. Protoconch small, white, round and with 2 volutions. Spire high and suture deep. Whorl light yellowish brown and carries angulated shoulder. Four spiral ridges of whorl sharp. Varix relatively thick with 4 spines which are expanded distally; uppermost one on whorl largest of them, long, gently curved and distinctly projected upward. The other 3 spines very small, short compared with the uppermost large Spine just mentioned. Two long and a very short spines visible on penultimate and its preceeding whorls. Varices run oblique to suture. Aperture suboval with thin outer lip. Columella very narrow and white. Siphonal canal extremely narrow and siphonal tube narrow, projected antero-leftward.
Holotype: Shell 28.1mm high and 26.5mm in maximum width, stored in the writer's collection, presented by MARTIN NANG in Cebu via NAKAYASU.
Locality: Off Cebu Island, Philippines.
Remarks: This species is near damicornis HEDLEY but is distinct by eminently curved siphonal tube, higher spire and more distinct varices. Species axicornis LAMARCK or longicornis DUNKER may be near in long spines but are clearly distinct by lower spire, straight siphonal tube and by weaker varix of last whorl, etc.
