Taranis gratiosa

The length of the shell attains 3.7 mm, its diameter 2 mm. The shell is very small. The spire-whorls contain 3 spiral cords, the uppermost feeble . The axial threads are distinctly retrocurrent and flexuous. The suture is distinctly margined. (Original description) The shell is very small and fusiform, characterized by its white, thin, and turriculate form. It features widely spaced spiral ribs and numerous distinct axial threads that are retrocurrent and flexuous. Sculpture: Below the smooth protoconch, the spire whorls exhibit a fine thread bordering the lower suture, a second very prominent spiral cord at the angle of the shoulder, and a third equally strong cord situated midway between the shoulder angle and the lower suture. The spaces between these cords are concave and broader than the cords themselves. The body whorl features six spiral cords descending from the shoulder angle toward the base; the upper three are robust, while the lower ones are closer together and less pronounced. The base displays a few indistinct spirals. The axial sculpture consists of fine, nearly equidistant threads that are slightly retrocurrent on the shoulder and become flexuous further down. …
