Shell up to 72.2 mm, fusiform, stout, with broad spire angle, 9 or 10 convex, shouldered whorls with slight subsutural concavity. Suture wavy, following axial sculpture of preceding whorl on ribbed upper part of the spire, straight on lower whorls. Spire tip white, latter whorls flesh coloured, inside aperture light brownish or whitish.
Protoconch rather large, white, 1 to 1,25 whorls, smooth and glossy, sometimes with axial growth lines on final part, ending in a varix. 1.0 mm in diameter.
Strong, close-set axial ribs on upper teleoconch whorls, traversing from suture to suture. Interspaces narrow and deep. About 9-11 narrow and distinct ribs on upper whorls, suddenly becoming lower and broader, and fading away on penultimate whorl.
Teleoconch begins with 4 strong spiral cords. 2 additional cords appear on second whorl: one immediately below suture, the other just above lower suture. From third whorl on, a fine secondary spiral thread appears between each pair of primary cords, becoming soon as strong as primary ones. In addition very fine intercalated tertiary spirals appear. This fine spiral sculpture is crossed by strong close-set axial growth lines, giving the surface the texture of linen.
Aperture ovate, white or light brownish coloured. Outer lip thin, edge slightly crenulated, inside smooth or inconspicuously lirate. Parietal callus thin, smooth, columellar folds absent. Siphonal canal rather short, about as long as aperture, curved, slightly bending backwards.
Periostracum thin, greenish, well-adherent.
Operculum typically fusinid, reddish-brown, corneous, shape and size corresponding to aperture, with terminal nucleus.
Radula typically fusinid. Central tooth small, broad, top and both sides concave, base convex, tricuspid, cusps of about equal size, projecting below base. Lateral teeth curved, having 6 or 7 rather small, short, pointed cusps with incurved tips. Small denticle at inner end.

Comparison: F. chrysodomoides has a less constricted suture, a white to brownish shell, coarser and less numerous axial ribs on upper whorls, and a finer, more close-set spiral sculpture.
F. graciliformis has a more elegant shell with elongate spire, a larger adult size, less ventricose, less convex and longer whorls, and has a weaker spiral sculpture with a larger number of intercalated fine threads on body whorl.

Range and habitat: Philippines, Bohol, 200-540 m deep. One record from Indonesia, Tanimbar Islands, 271-273 m deep, and one record from New Caledonia, 435 m deep.
