Shell rather large (up to 77.2 mm), relatively heavy in weight. Background colour whitish to yellowish with pale reddish coloured spiral sculpture. 9 or 10 convex whorls, latter whorls distinctly keeled, shoulder slope clearly concave. Axial and spiral sculpture rather weak. Aperture relatively large, siphonal canal short and distinctly curved. Protoconch broken in all known specimens. Suture appressed to the preceding whorl, wavy on upper whorls, straight on penultimate and body whorl.
Upper postnuclear whorls slightly convex, sculptured with 9 or 10 narrow and rather weak axial ribs, reaching from suture to suture; interspaces between them narrow and only weakly impressed. Beginning at the appearance of the peripheral keel (usually on fourth or fifth teleoconch whorl) the inter-spaces between the axial ribs become wider; the ribs terminate below the upper suture and are reduced to broad, rounded knobs which are most promi¬nent at the periphery. On the penultimate whorl they become weaker and irregular, fading out suddenly. About 9-13 axial knobs on latter whorls, but usually obsolete on body whorl and sometimes also on penultimate whorl.
Four strong spiral cords on the first teleoconch whorl, 5 or 6 on the following whorls. On latter whorls, beginning with the peripheral keel, several rather fine additional spiral threads appear on shoulder. Starting with third or fourth postnuclear whorl a fine spiral thread appears between each pair of stronger cords. The number of fine threads increases by intercalation; up to 8 fine intercalated threads of unequal strength on body whorl. Central spiral cord and the 2 cords below it somewhat stronger than all others. Spiral sculpture crossed by conspicuously strong growth lines, well-visible on all whorls.
Aperture rather large, narrowly ovate, acute at posterior end, yellowish or white in colour. Outer lip simple and sharp, without or with only weak internal lirae. Inner lip appressed to parietal wall, smooth. Columellar folds absent. Siphonal canal rather short for genus, shorter than aperture length, slightly curved, widely open. Outer side ornamented with fine spiral cords and numerous intercalated threads.
Operculum rather thin, colour pale reddish brown, corneous. Shape and size corresponding to aperture, typical of genus, with terminal nucleus.
Radula typical of the genus, consisting of an elongated central tooth with a tricuspid base. Median cusp clearly longest. Rounded base broader than notched top. Lateral teeth conspicuously broad, strongly curved with 7-8 rather short, strong and pointed cusps; 2 outermost cusps broader and stronger.

Rediscovered by HADORN AND FRAUSSEN (1999), the typically fusinid radula was figured for the first time. A specimen from off the Somalian coast figured as F. subangulatus "broad form" is now referred to F. jurgeni Hadorn and Fraussen, 2002.
F. jurgeni has a larger adult size and has a broader shell, a longer siphonal canal, a larger number of spiral cords which arc clearly finer and denser.
F. chrysodomoides is most similar to F. subangulatus and can be distinguished by having a somewhat larger adult size, uncoloured spiral cords, a larger number of weaker spiral cords, often broader and somewhat stronger axial ribs, a more ventricose body whorl, stronger axial growth lines, usually a more curved siphonal canal and finally some minor differences in radula morphology.

Range and habitat: East Africa, from Djibouti, Gulf of Aden to the Pemba Channel, Tanzania, 400-1134 m deep on blue silt and pteropod ooze.
