Conus pernodosus (Pilsbry & Johnson, 1917)

Description ⁽²⁾

The shell is rather slender, the diameter not quite half the length; spire produced, slightly concave in the upper part, of about 9 whorls, which are slightly concave and spirally striated above, with a projecting periphery which is set with somewhat pointed tubereles on the last 31 whorls. On the angle of the last whorl there are 11 tubereles. Below the angle the outline is very slightly convex. Surface closely sculptured with flat-topped spiral cords about twice as wide as the intervals (37 below the angle of last whorl); intervals are sharply sculptured with axial threads.

Length 23.3 (imperfeet at base); diam. 12.3 mm.

With the type, No. 2552, A. N. S. P., there are two young shells about 15 mm. long, which show tubereles on the last whorl only. The upper whorls, in this species, have a smooth, projecting periphery
