Geographical distribution and bathymetry
In
New Caledonia
, most specimens were sampled in locations across Norfolk Ridge, but also on the Loyalty Ridge and in the
New Hebrides
Arc (Hunter Island), at depths ranging from
300 to 1000 m
and beyond, typically at between 500 and
900 m
(
Fig. 13
). Also present in Kermadec Ridge,
New Zealand
, where several specimens were dredged alive from
1030–1180 m
off Curtis Island, making this species one of the deepest-living ones among the known cone snails. Several empty shells matching
P. puillandrei
from Balut Island, Mindanao,
Philippines
, have been examined. The identity of these specimens from the
Philippines
could not be confirmed by radular or DNA studies, but the conchological features seem consistent with the identification of these specimens as
P. puillandrei
. This might represent a significant range extension to the southern
Philippines
(Tenorio & Castelin 2016).

Remarks
Shell moderately small to medium-sized (maximum length 57.0 mm). Protoconch multispiral, with 3–3.5 whorls, white to yellow-brown (
Fig. 12L
). The shell of
P. puillandrei
has a distinct shoulder ridge, usually smooth but sometimes nodulose. Nodulose specimens may resemble a small
Profundiconus teramachii
. However, this species attains a larger size, has a lower spire and usually exhibits a broadly carinate shoulder. Radular tooth (
Fig. 12M
) small. Anterior portion of tooth shorter than posterior section, bearing one barb and a pointed blade which covers 50–62% of anterior portion of tooth. External cusp present, laterally widened and serrated, with 4–5 small denticles. Fringe of closely spaced projections pointing towards apex immediately below waist. Shaft fold present. Slanted base with a large and prominent basal spur. The sequenced specimens of
P. puillandrei
, both smooth and nodulose at the shoulder, form a clade sister to
Profundiconus neotorquatus
(
da Motta, 1985
)
,
P. neocaledonicus
,
P. teramachii
and
P. smirnoides
(
Fig. 2
).
