Remarks

Original Description (from Maury, 1910, p. 128):

"Shell slender, acute, with ten whorls, of which the three nuclear are smooth and shining; spiral sculpture of fine, subequal threads with wider interspaces. The threads extend over the sub-sutural grooves and thus cover the entire surface of the shell except the three nuclear whorls; transverse sculpture of well-marked riblets which extend from the base of the sub-sutural groove to the succeeding suture and down over more than one-half the body-whorl; aperture rather narrow; outer lip somewhat thickened near the edge; notch deep, distinct, U-shaped; pillar with a moderate callus; canal very short, open. Length of shell 13; of aperture 5; greatest width 4.5 mm.

Chipola marls, Bailey's Ferry, Florida.

Cornell University collection.

Named in honor of Professor Van den Broeck, Director of the Geological Survey of Belgium."
