It is longitudinally crossed by reddish or dark brown stripes, often broken into tessellations on the base.

It is red, with four regularly spaced triangular sectors of greenish yellow, on the last turn and one on the whorl preceding this.

The cords of the early turns are of the most intense red, equaling the base in the brilliancy of this color.

In addition to the above sculpture, the spire is marked by rather strong, closely spaced, retractive incremental lines.

The outer lip is thin at the edge where it is rendered sinuous by the strong spiral cords.
