Vexillum amabile (common name the friendly mitre) is a species of small sea snail (marine gastropod mollusk) in the family Costellariidae, the ribbed miters.
Description Vexillum amabile's shell size varies between 10 mm and 20 mm.
Its shell has a short rhomboidal shape, with an obtusely depressed spire. Its whorls are somewhat rounded, and it has smooth, wave-like ribbings along its length and transverse grooves around its circumference. The columella of the shell is four-plaited. Its aperture is rather short, with a brown interior.Reeve, L. A. (1844-1845). Monograph of the genus Mitra.

The outside of its shell is ashy to pinkish gray in colour. It has a broad white superior band, and sometimes has narrow white lines revolving below it.Tryon (1882), Manual of Conchology IV
