Conus yaquensis

Geological Range

Late Pliocene; Extinct.

Paleogeographic Distribution

Southern Florida.

Remarks

First English Description (from Pilsbry, 1921, p. 331):

"This cone resembles C. proteus closely in shape except that the the spire is lower, with much less concave outlines, the apical angle much wider. The spiral furrow below the suture is deeper. In color it is a "negative" of C. proteus, the spots being white, the intervals ferrugineous. This color affects the texture of the shell, the white spots resisting erosion. In one worn specimen there are spiral series of pits along the colored bands. The anterior third of the last whorl has a few narrow raised spirals.

Length 49, diam. 30 mm. Type.

Length 40, diam. 23 mm. Paratype.

The two specimens are no. 2547 A.N.S.P."
