subaequalibus alte spiraliter sulcatis, sulci circ. viii, latera costarum crenu- 
lantibus, costas haud superantibus; basi valde rotundata, curta, haud 
sculpta; axi lacunato; peritremate vix continuo; columella recta. Long., 
.18; long, spir., .14; lat., .05 poll. (Carpenter.) 
Shell elongate-conic, milk-white. Nuclear whorls small, two forming 
a depressed helicoid spire, the axis of which is almost at right angles to 
that of the succeeding turns, in the first of which it is about one-fourth 
immersed. Post-nuclear whorls moderately rounded, slightly shouldered 
at the summit, weakly contracted at the periphery, ornamented by slender, 
sinuous, protractive, axial ribs, of which twenty-four occur upon the 
first and second, twenty-two upon the third, twenty upon the fourth to 
sixth, twenty-two upon the seventh and penultimate turn. Intercostal 
spaces about one and one-half times as wide as the ribs, well-impressed, 
marked by six strongly impressed series of pits which extend up on the 
sides of the ribs but do not cross them; the peripheral and the third 
posterior to this are of equal strength and stronger than the rest. The 
space between the third and fourth above the periphery is a little wider 
than that between the others, which are about equally spaced. The space 
between the summit and the first spiral line below it is about equal to about 
double the space included between the other spirals. A finely incised 
line divides it into equal areas. Sutures strongly impressed, rendered 
wavy by the ribs. Periphery well-rounded, marked by the feeble con¬ 
tinuations of the axial ribs and a few distantly spaced spiral striations. 
Aperture oval; posterior angle obtuse; outer lip thin, columella moderately 
strong, sinuous and slightly reflected. (Bartsch.)

Shell moderately large, elongate-conic, flesh colored. Nuclear whorls 
decollated. Post-nuclear whorls rather high between the sutures, moder¬ 
ately shouldered at the summit, marked by numerous, well-developed, 
almost vertical, axial ribs, of which eighteen occur upon the second and 
third, twenty upon the fourth, twenty-four upon the fifth, twenty-eight 
upon the sixth, thirty upon the seventh, and thirty-four upon the penul¬ 
timate turn. Intercostal spaces strongly impressed, about as wide as the 
ribs. In addition to the axial sculpture, the whorls are crossed by five 
strong lines of pits, which are distributed over the anterior two-thirds
