This uncommonly encountered snail has a long and narrow shell that is usually a uniform brown colour, with white spiral cords. It is very similar to others of its genus, particularly S. marmorata, which shares the brown colouration and white cords. However, that species has distinct widening at intervals on the cords, givine them the appearance of having white "pulses" along their length. The birght orange S. crocea is a similar shape, but its distinctive colouration gives it away.
