Diagnosis: Shell small, white or yellowish white, often with a pale yellow band below suture on body whorl; not strongly narrowed anteriorly; spire low; aperture moderately narrow, narrowing anteriorly; inside of outer lip smooth, denticulate in very mature specimens, moderately thickened internally, thickest centrally; external varix present; siphonal notch absent or weak; posterior notch weak; ventral callus absent; columella with four strong plaits occupying slightly less than half the aperture, 4th fold slightly remote.
Size: Adults 5-6 mm in length.
species has a taller spire than M.
stilla but not as tall as M.
translucida. It is a
subtidal species, as is M. stilla,
while M. translucida is one of the common beach species.
Remarks: The specimen illustrated here (Fig. 1) was compared with the type in the British Museum by Hedley, and found to be correctly identified (Hedley, 1915, p. 272).
