Conus
haughtoni (King, 1953)
Description:
Shell
about 35 mm. in height, with spire low or of medium height. Body whorl not
inflated, contracting regularly to the anterior end, outline smooth. Shoulder
broadly rounded, whorls convex, distinct. Sculpture on the anterior half of the
body whorl, of well-spaced grooves, alternately broad and narrow, otherwise
smooth. Anterior end truncate, sinus very weak. Posterior sinus also weak or
absent. Columella with a very slight twist, low down. Juvenile specimens have a
proportionately higher spire and an ornamentation of spiral grooves, one-third
as wide as the flat intervening, spiral ridges extending from the anterior end
to just beneath the rounded shoulder. Juveniles are also proportionately more
slender than adult shells.
The nearest relative is probably C. avaensis Noetling,
from Burma. The species is named for Dr. S. H. Haughton, in recognition of his
many years of palaeontological research in South Africa, and especially of his
studies upon the Tertiary marine palaeontology of the Oape Province and
South-West Africa. After Aequipecten uloa, C. haughtoni and C. proliferatus
are the most abundant species at the Uloa locality (Sudafrica) (1).
In my opinion, a correlation with Conus martini (Shuto, 1969) = Conus
dingleanus (Beets, 1984) cannot be excluded, a species described after 1953
and therefore King could not know.
