Taxonomy Wells (1994) excluded mastersi from Inquisitor, but did not suggest an alternative generic allocation. It is thus here kept provisionally in InquisitorWells, Fred E. "A revision of the Recent Australian species of the turrid genera Inquisitor and Ptychobela." Molluscan Research 15.1 (1994): 71–102.
Description The reddish brown, solid shell is ovate and depressly flattened at the upper part. It contains 8, transversely sculptured, whorls. The centre of the upper whorls is tuberculated, spotted with white, the last longitudinally rather obliquely ribbed. At the angle they become more like prickly nodules, below somewhat white. The suture is minutely spirally striated. The outer lip is simple, brownish in centre, having an obsolete white sinus below. The upper sinus is white, deep, and wide, with a thick deposit of callus on the body whorl, and extending down in a thin plate to the columellar. The siphonal canal is very short and wide.
