Conus berryi (Spieker, 1922)

 



Shell small, biconic, the altitude little more than 1,5 times the diameter, and the cone of the body whorl about 1.5 times the length of the spire. Whorls about 9 in number, the sur

face of each whorl inclined from the suture to a sharp keel, from which it recurved to the suture. The spire is thus
turreted. The keel is waved, giving the spire a coronate appearance. Sculpture of slightly arcuate lines of growth on the spire ; on the sides of thebody whorl are spiral bands
separated by narrow interspaces. The lower bands are very sharply defined, but they decrease in sharpness of definition
above. Faint lines of growth cross the bands. The aperture is narrow (1).

 

Height, 17; diameter, 10.75 mm.


This species is similar to C. marginatus Sowerby from Antillean Miocene horizons, from which it differs in having a higher spire, which is coronate, not smoothly keeled (1).

C.multiliratus var. gaza Johnson and Pilsbry is similar to both these forms ; it differs from berryi in being more tapering, longer, with a proportionally lower spire, the whorls of which are not coronately keeled (1).


Lower Zorritos. Hervideras, Zorritos district (1).
