First English Description (from Reeve, 1843, p. 68):
“The laughing Triton. Shell elongately ovate, somewhat fusiform, rather solid, distorted, with five or six rather indistinct varices; spire acuminated; whorls elegantly latticed with prominent, narrow, raised ridges, transverse ridges duplicate; pale bluish white, covered with a velvety epidermis; columella strongly wrinkled, stained with orange; canal rather short, scarcely turned upwards; aperture small, contracted; lip strongly toothed within, white, bordered with orange.
Although this species exhibits little more than a modification of the characters of the preceding, the difference is of good specific importance. The cancellated sculpture is wider and more prominent, whilst the ridges are more sharply noduled in crossing over each other. The wrinkles and denticulations which surround the aperture are much more strongly developed, and the orange-stained colouring of the enamelled disc is peculiarly characteristic.”
