Hedley (1922):
The genus Eucithara seems to be a constant associate of reef corals. Typically it is a rather solid turrited-fusiform shell, sculptured by bold longitudinal ribs, over-run by dense spiral threads, and decussated by an even finer radial striation. The aperture is as long, or longer, than the spire, fortified externally by a stout varix which ascends the previous whorl, includes a semi-circular sinus, and extends a free edge over the mouth. Within the lip are a series of short entering ridges, and the columella bears a corresponding series of deeply entering horizontal bars.
Powell (1966):
Shell fusiform to ovate-biconical, solid, of moderate size, up to 22 mm., but mostly within the size range of 5-12 mm. Protoconch small, erect, narrowly conical of 2 ½ whorls, first 1 ½ whorls smooth with an inrolled tip, the last whorl with numerous concavely arcuate thin axials, ending abruptly at the commencement of the post-embryonic sculpture. Adult sculpture of bold lyrate axial ribs, overridden by spiral cords and threads. Aperture long and narrow, as long as, to even longer than the spire, and terminating in a short, often undifferentiated, distinctly notched anterior canal. Outer lip strengthened by a heavy external varix, which is excavated or channelled subsuturally by a moderately deep rounded sinus. Both the inside of the outer lip and the columellar lip with numerous plicae or denticles. Colour usually white, with or without intermittent brown bands, sometimes blotched in brown on the dorsal surface of the body-whorl and the anterior end.
