Description

The thin shell is fusiform or subcylindrical. The colour ranges from uniform buff, with or without chocolate spiral lines or bands, to entire chocolate. The protoconch consists of two or three smooth helicoid whorls. Fasciole don't interrupt the sculpture, and are scarcely indicated by the curvature of growth lines.

Sculpture :—The radials vary from bold spaced ribs projecting at the shoulder to fine close riblets. The entire shell, except the protoconch, is overrun with fine, close, beaded or unbeaded threads. The aperture measures about half the length of the shell, with or without armature. The outer lip is slightly inflected. The sinus is subsutural, deeply rounded. The siphonal canal is short and open.^[2]

Distribution

This genus of marine species occurs off Sumatra (Indonesia) and Australia (New South Wales, Queensland, South Australia, Tasmania, Victoria, Western Australia). One species, Guraleus amplexus, occurs off South Africa, another, Guraleus kamakuranus off Japan and Korea.
