The teeth are rather narrow, slightly curved and sharply pointed, without barb or cutting edge. The accessory limb is moderately large and attaches to the major limb about just behind the tip. Anatomy. (p. 81) The foregut anatomy is described in Kantor et al. 1997 Remarks. On shell characters, it is difficult to assign this species to any genus of Crassispirinae known from Western Australia and the entire Indo-Pacific. Its radular teeth are very similar to those of species of Inquisitor Hedley, 1918 (see Taylor & Wells, 1995). In general shell outline the new species resembles some species in- cluded by Wells (1994) in the genus Inquisitor Hedley, 1918 namely /. dampierius (Hedley, 1922) and, to a lesser extent, /. odhneri Wells, 1994, but is readily distinguished from them (and from any known turrid species) by the peculiar character of the sculpture of branching axial folds and widely spaced spiral grooves. However, the two latter species are themselves not very similar to the type-species of Inquisitor, I. sterrhus (Watson, 1881), and other typical representa- tives of the genus, which are characterized by a slender shell with a well differentiated and relatively long siphonal canal. Unfortunately, the radular characters
