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
).

L
. Protoconch of specimen I.
M
. Radular tooth of specimen from S Île des Pins, 302‒311 m depth, 26.1 mm. Scale bars = 10 mm, unless otherwise stated.
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.
