Biology Type of larval development: direct (non-planktotrophic), inferred from paucispiral protoconch. [details] Diagnosis Shell up to 72 mm, elongate fusiform, moderately solid. Protoconch 1 1/4 slightly convex whorls, with globose nucleus and subsequent whorl constricted, with maximum convexity near the suture; the later part with delicate axial folds. Teleoconch of 7-8 whorls. Spire whorls convex, slightly shouldered, with 10 strong, widely spaced axial folds overrun by spiral cords. Three major spiral cords throughout teleoconch whorls, forming elongate knobs at intersection with straight, slightly prosocline axial folds; smaller subsutural and suprasutural cords added from penultimate whorl onwards. Body whorl with rounded periphery and a long, straight, tapering siphonal canal, with ca. 20 spiral cords, somewhat unequal in size but not alternating, less prominent towards the tip of the canal. Aperture oval, merging abapically into the quite open siphonal canal. Parietal edge bearing anteriorly a very weak knob, very close to the attachment of the outer lip. Columellar edge smooth, appressed. Outer lip with a thin edge, smooth inside, weakly notched at the termination of the spiral cords. Inside of the aperture with very faint spiral grooves in the deeper visible part. Colour of protoconch whitish; teleoconch also whitish, grading to a very faint tan colour between the axial folds.
The closest relationship as can be inferred from morphology is with F. bocagei (P. Fischer, 1882), mainly distinguished by being smaller (large specimens on the seamounts reach 30 mm) and having a multispiral protoconch [details] Distribution Endemic of the upper part of Great Meteor seamount (330-470 m), Hyères seamount (310-480 m), and Irving seamount (260-460 m).
