Conus tuberacola (Anderson, 1929)
Shell of medium size,
probable height of holotype (incomplete) 54 mm., width 3.4 mm., spire high,
concavely turritecl, earlier whorls coronated; last two or three whorls smooth,
but slightly excavated above; sides of older specimens smooth, in younger
shells the sides are adorned with minute spirally arranged beads, chiefly on
the lower half of the shell; aperture narrow. The shoulders of the last whorl
sharp and abrupt; lines of growth strongly curved (1).
This shell resembles C. consobrinus Sow., only in sculpture, but is relatively wider, has less
strongly developed granulations on the sides. It also differs from C.
toroensis Olsson in relative width and in form of spire (1).
Holotype: No. 4623,
Mus. Calif. Acad. Sci., from Loc. 267, C. A. S., horizon M - N, near base of
the Tubera group, where it appears to belong, and where several fair-sized
specimens were obtained: Miocene of Colombia. (1)
