Description
editThe size of an adult shell varies between 5 mm and 14 mm.
(Original description in Latin) The smotth shell is obese and awl-shaped. It is white, adorned with pale longitudinal brown spots. It features a few subrounded whorls, with the body whorl biseriately spotted. The spire is obsoletely folded. The aperture is oblong, and the columella is truncated. [2]
(Described as Columbella acus) The shell is narrowly elongated. It features minutely ribbed longitudinal patterns towards the apex. Its color is yellowish, irregularly streaked with orange-brown. The whorls are rather flattened. The aperture is very small, and the columella is slightly excavated and truncated. The outer lip is simple and scarcely denticulated within. [3]
Distribution
editThis species occurs in the Caribbean Sea and the Lesser Antilles; in the Pacific Ocean from Colombia to Argentina in the Atlantic Ocean.
