Leptadrillia maryae

The length of the shell attains 7.9 mm. Shell is very small and narrowly fusiform. It is glossy and translucent. The whorls are moderately convex with peripheries just below mid-whor. There are 9¼, the last of which is approximately 56% of the total length;. The aperture is narrow, with the anal sinus and anterior canal only slightly narrower and a sculpture of axial ribs. Protoconch is approximately 3 smooth, round translucent whorls. A spiral sculpture is largely absent except for threads on the anterior fasciole. There is no sulcus. The outer lip is thin, with 2 slender strengthening axial folds; lip edge flexed only slightly outward near the anal sinus, otherwise projecting out in a nearly circular arc from the anal sinus to stromboid notch; stromboid notch shallow and wide. Anal sinus deep, U-shaped, offset from the axis of the shell by the parietal wall and lobe and slight outward flex of the outer lip near the sinus such that it appears spout-like. The inner lip is narrow, recumbent, margined; thicker on the anterior portion of the columella, and developed into a weak parietal lobe posteriorly. Anterior canal is long, open, and turned right at its end when viewed ventrally, unnotched; fasciole is not swollen, and spiral threads are present. The shell is pale golden brown, ribs, anterior canal and outer lip are lighter.^[2]
