Distribution

Beibu Gulf to Philippines, and west to the Gulf of Thailand and Andaman Islands.

Remarks

Although this species has frequently been misidentified, the Chinese material agrees with photographs of the holotype (Kilburn manuscript) and with Thai and Andaman specimens. Inquisitor intertinctus is characterised by its prominent, wavy and crested spiral cords, which cross the axial cords, each whorl having a strong varix.
