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.
