This species was named by W.H. Dall after the American malacologist Addison Emory Verrill (1839-1926), the first professor of zoology at the Yale University

Description

The shell grows to a length of 5.5 mm.

(Original description) The shell resembles Drillia oleacina on a very small scale. It is white, with a large white, smooth, inflated protoconch. It contains six or seven whorls, rounded, polished, translucent waxen whitish. It is transversely sculptured by twelve to fourteen rounded, stout, strongly raised ribs extending forward from the notch-band to the suture, or on the body whorl to its anterior third. On the last half of the last turn it is evanescent. The suture is appressed The lines of growth are evident. There is no spiral sculpture visible. A decided callus with a groove behind it is visible on the columella and the body whorl notch, as usual in the adult, rather deep. The aperture is rather wide behind, and shaped as in Drillia oleacina.[3]

Distribution

This species occurs in the Gulf of Mexico and the Caribbean Sea at depths between 73 m and 567 m.
