Vexillum hendersoni is a species of small sea snail, marine gastropod mollusk in the family Costellariidae, the ribbed miters.[1]
Description
The length of the shell attains 17 mm, maximum diameter 6 mm.
(Original description) The small shell contains about seven whorls exclusive of about three small smooth brownish whorls in the protoconch. The color is whitish with a brownish base darker near the periphery, which appears as a narrow brown band just behind the suture on the spire. The axial sculpture consists of (on the body whorl about 10) rather sharp, nearly vertical ribs with wider interspaces, obsolete near the siphonal canal; s. The spiral sculpture consists of (on the penultimate whorl about eight) rather feeble flattish threads stronger and more widely spaced toward the siphonal canal from which they are separated by a distinct sulcus. The siphonal canal carries two or three much stronger spiral threads. The periostracum is pale and fibrous. The suture is distinct but not deep. The aperture is narrow. The outer lip is sharp, lirate internally. The columella has three plaits. The siphonal canal is moderately differentiated, slightly recurved.[2]
Distribution
This species occurs in the Caribbean Sea and the Gulf of Mexico; also off Bermuda
