Conus
longitudinalis (Pilsbry & Johnson, 1917)
Description.
The
shell is about twice as long as wide, with nearly straightly conic, elevated spire of about
10 whorls. These are flat, with an angle
projecting above the suture and on the last whorl. There are slightly arcuate, protractive
strise above. The last whorl, below the shoulder is coarsely corrugated
vertically, the wrinkles somewhat irregular.
The anterior third has narrow, spiral grooves, the upper three widely spaced, the rest
in pairs, and all crossed by axial threads (1).
Length 35, Diam. 17.5 mm.
This species is remarkable for its coarsely
wrinkled surface. It is known
by one specimen with the outer lip extensively broken, and the spire and part of the last
whorl of another (1).
