Conus limonensis (Olsson, 1922)
Descrizione e caratteristiche:
Shell rather large, but delicate
and rather slender; spire low, concave to the slightly projecting apex; spire
whorls 10 or more, nearly flat
between the sutures or slightly concave due to a slightly raised border; spire-whorls
with 3 or 4 low spirals which become
faint on the later whorls so that they are nearly smooth; sutures deep; shoulders of the last
whorl angled or somewhat raised;
body-whorl long and slender, polished and smooth, except for a few faint
spirals near the tip of the canal; anterior canal
long and straight, evenly tapering.
Length 41, breadth 24 mm.
This species is based on 2 specimens from
the coral limestones of Port Limon, where it is associated with Conus
stenostomus and planiliratus. From stenostomus, its straight
canal, low spire and
nearly smooth, polished surface is most noticeable.
