Geographical distribution and bathymetry
Solomon Islands, Australia (Queensland) and New Caledonia, typically between 100 and 400 m deep. Isolated specimens have been sampled at depths beyond 800 m. Also present in Fiji at depths between 292–311 m (Moolenbeek et al. 2008). It has been cited from Tuamotu Archipelago, French Polynesia, at depths between 490 and 835 m (Rabiller & Richard 2014).
Remarks
Shell small to moderately small (maximum shell length 35 mm), conical with a moderate to high concave spire. Protoconch multispiral with 3 or more whorls (Fig. 30L). Radular tooth (Fig. 30M) with an indistinct barb and a pointed blade covering about one third of the anterior section, which is much shorter than the posterior section. Shaft fold present. Basal spur is present on top of the slanted base. This is an abundant species around New Caledonia, and it has been sampled in multiple locations. Although fairly constant in shell shape, it may be variably patterned, and pustulose specimens (Fig. 30J) ocassionally occur. The species has often been confused with Conasprella wakayamaensis (Kuroda, 1956) and C. eugrammata (Bartsch & Rehder, 1943), but these two species are not present in New Caledonia. In the phylogeny (Fig. 2), all specimens assigned to the taxon C. baileyi appear deeply nested within the Conasprella clade.
