Dorsanum miran, the Moroccan bullia, is a species of sea snail, a marine gastropod mollusc in the family Nassariidae, the nassa mud snails or dog whelks.

The elongated spire is formed of eight slightly convex whorls.

The sutures are edged with a yellow border, and a little beneath with another violet band: These two zones are much more perceptible upon the lower whorl.

The columella is slightly elongated, twisted at its extremity, and provided outwardly, at its origin, with two keels.

[2] This species occurs in the Atlantic Ocean off Morocco, Senegal and Angola.
