Adult shell of variable size in adult stage (70 to 135 mm), fusiform, solid and heavy. Surface glossy. Spire moderately high with strongly angled convex whorls. Protoconch with mean diameter of 10-12 mm, of 3.5 convex whorls, slightly flattened and incised by a deep suture, bearing at apex a short calcarella, and sculptured by numerous strong radial cords. First embryonic whorl smooth. Protoconch-teleoconch transition very gradual, radial cords becoming prominent broad axial rounded costae, close-set onto entire teleoconch, circa 30 on antepenultimate whorl. Suture very impressed. Teleoconch of 4 slightly convex whorls with deep, concave subsutural zone forming distinct shoulder. Aperture long, narrow, forming approx. 70% of total length of shell. Outer lip smooth and simple, solid and thickened. Columella straight with 4, rarely 5, thick plaits, the abapical more oblique. Siphonal notch deep. Fasciole present. Background colour cream overlain by indistinct orange zigzag axial stripes, forming a tent-like pattern and crossed by 4 spiral bands of large blotches. Calcarella and embryonic whorl orange, subse¬quent whorl white.

The prominent axial ribbing makes this species unmistakable. V. hargreavesi is entirely smooth with a relatively smaller and dome-shaped protoconch. The relationship with the other axially ribbed western species V. calcarelliformis is more problematical. The latter usually has a smaller, more elongate shell. The protoconch is more flattened. The axial ribs are finer and more numerous, tending to be attenuated on the last whorl. Its tentlike pattern is well-defined and dense. When fresh, its reddish coloration with a black embryonic whorl and calcarella is a specific character.
Though long considered subspecies of V. hargreavesi, V. daisyae must be raised to full species rank, as suggested by Weaver himself when describing this taxon, because there is no apparent intergradation in the North West Cape area where ranges of the two species overlap. A dead and worn small specimen has been trawled at 450 m on the Rowley Shoal. As it is a unique specimen, we cannot draw from this discovery whether it is an erratic shell or a true fossil displaying an ancient extension of the present range.
It remains a rare and poorly known species.

TYPE LOCALITY
Southwest of North West Cape, central Western Australia, 22°00'S/ 113°45'E.
RANGE
From Dongara north to North West Cape, central Western Australia.
HABITAT
One live specimen was brought up from 215 m (Weaver, 1967). Generally specimens are hermit-crabbed from craypots between 45 to 130 m.
