They are ornamented by strong, narrow, protractive axial ribs.

The grooves are crossed by numerous, very slender, somewhat protractive axial riblets.

Of the ribs which are slightly protractive, 17 appear upon the first to third and 19 upon the penultimate whorl.

They are marked by very strong, slightly protractive axial ribs, of which 14 occur upon the first to fourth and 16 upon the remaining turns.

They are ornamented with very low, flattened, somewhat irregular, protractive axial ribs, which are best developed on the early whorls.

The sculpture shows about fourteen strong, almost vertical, scalariform axial ribs on the second, and sixteen quite protractive ones on the succeeding whorls.

The entire surface of the spire and base is marked by slightly protractive lines of growth and many very fine, closely spaced spiral striations.

They are ornamented by weak, distantly spaced, somewhat protractive axial ribs, which become flattened and decidedly enfeebled near the summit.

They are marked by sublamellar, protractive axial ribs, which extend undiminished to the summit of the whorls, rendering this crenulated.

They are marked by strong, broad, well rounded, somewhat protractive axial ribs, of which 20 occur upon the first to sixth, 22 upon the seventh to ninth,and 24 upon the penultimate turn.

The deep channels between the keels and the shoulders are crossed bv slender axial riblets which have a protractive slant on the shoulder and are decidedly retractive in the channels.

These ribs have a decided protractive slant on the early whorls, while on the middle turns they are vertical, and on the later volutions they have a decidedly retractive slant.

The whorls are ornamented by strong rather distantly spaced, moderately acute, slightly protractive axial ribs, of which 18 occur upon the first three, 16 on the next three, 18 on the seventh, and 20 upon the penultimate turn.

Why then, you princes, Do you with cheeks abash'd behold our works And call them shames, which are, indeed, nought else But the protractive trials of great Jove To find persistive constancy in men; The fineness of which metal is not found In fortune's love?
