Tritia lanceolata
Tritia lanceolata is a species of sea snail, a marine gastropod mollusk in the family Nassariidae, the Nassa mud snails or dog whelks.
Description
The length of the shell attains 15 mm, its diameter 6.5 mm.Very elongated variety, finely ribbed, also found on sponges
The shell is bulging and strongly ribbed. On the first whorls, the ribs are arched; on the body whorl, they are flexuous. The ribs and the intervals are furrowed by decurrent striae which create a reticulation less pronounced than that of Tritia reticulata, to which this species bears a resemblance. The aperture is weakly compressed on the side of the outer lip; the mode of coloration is similar to that of Nassa subdiaphana.
