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).
