Trophonopsis muricata

The narrow, conical shell has seven or eight tumid whorls, crossed by numerous transverse ribs (15 to 20 on the penultimate whorl), spiral ridges and fine growth lines.

These ribs are narrow and interact with spiral ridges, forming a deep reticulate pattern with raised tubercles.

The thin outer lip is straight, crenulate andshows internal grooves.

This siphonal canal is long about 25 % of the length of the shell), narrow and almost straight.

The color of the shell is yellowish (often with spiral brown bands), flesh-colored or sometimes white.
