Guraleus alucinans is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. Description The length of the shell attains 12 mm, its diameter 3 mm. (Original description) This is one of the most widespread and variable of Australian marine temperate gastropods. . The short fusiform shell contains 7–8 obtusely angulated whorls. This species may be distinguished by its thick, rounded, straight ribs. The spiral grooves are more or less distinct. Some specimens are nearly white ; in others numerous sienna brown spiral lines, which extends from the angle down to the suture, cross the ribs, interrupted by the interstices, as in Guraleus pictus. There is generally a brown line just above the angle. Distribution This marine species is endemic to Australia and can be found off South Australia and New South Wales.
