Conus
crenospiratus (Anderson, 1929)
Shell small, height of holotype 17
mm., width 10 mm., with graceful outline, low spire and somewhat rounded sides;
in size, form and sculpture it recalls C. isomitratus Dall, from the
Chipola beds of Florida; upper surface of the whorls flattened ; sutures
distinctly incised, but unlike Dall's species, the shoulders of the whorls are
tuberculated, forming on the inner side of the suture a wavy, or crenulated
line; body whorl ornamented by spiral lines, which become obsolete near the
shoulder, but become stronger on the lower third of the whorl ; spiral threads
are here flattened, or slightly concave in section, having the appearance of
being double (1).
Holotype: No. 4624, Mus. Calif. Acad. Sci.,
from Loc. 351. C. A. S., near Punta Pua, near the middle of the Tubera group,
Colombia; Miocene.
