Vasum globulus is a rare species of medium-sized predatory sea snail, a marine gastropod mollusk in the family Turbinellidae, subfamily Vasinae, the vase snails.

Subspecies:

• Vasum globulus nuttingi (J. Henderson, 1919) (synonym: Turbinella nuttingi J. Henderson, 1919)

Description

The shell of the species is almost spherical, which is unusual in vase snails, hence the specific name globulus. The maximum recorded size of the shell is 43 mm, but it is small compared to that of other species in the same genus.

Distribution

This species appears to be endemic to a few small islands in the Leeward Island chain of the Lesser Antilles, West Indies. It has been recorded from the following islands:

• Barbuda
• Antigua
• Sint Eustatius
