Agulhas Bank, from Algoa Bay to Cape St Blaize;
100–210 m
(living

Notes.
The
type
material of this species is composite. The specimen from off Cape St Blaize (
SAM
A
9296
), which was the one figured by both
Barnard (
1963
a)
and Kensley (
1973
), even though it is in very poor condition, is without doubt a juvenile of the species that I subsequently described under the name
Herbertina hayesi
(
Herbert
1995
)
. The second specimen (
SAM
A
9297
) from off Cape Morgan [Kei Mouth], which is in much better condition, is also a juvenile species of the same genus, but as noted by Barnard, it lacks the coarse ‘goose-skin’ sculpture of the illustrated specimen. It is in fact almost certainly a juvenile specimen of
Bruceina eos
. Since Barnard’s name predates both of the other names, one of the junior names must be relegated to synonymy. That Barnard drew attention to the sharp upstanding points on the spiral cords of the second and third whorls of his Cape St Blaize specimen and that this was the one he chose to illustrate, despite it being broken and flaking, indicates that this was the one he considered best typified the characters of his species and from which he derived the specific epithet
chenoderma
[=goose-skin]. I therefore select this specimen as the
lectotype
(
SAM
A
9296
) and place
Herbertina hayesi
in synonymy with
Calliotropis chenoderma
, at the same time transferring the latter to
Bruceina
. Barnard was prone to base new taxa on poor quality material, and the descriptions and figures of the species are often compromised as a result—an unfortunate aspect of his otherwise valuable legacy.
