( Figure 3H )

Inquisitor minimarus Kosuge, 1993, p 11 , 12, pl. 5, figs 1, 2, text fig. 1 (protoconch); Wells 1994: p 91, pl. 4, figs 7, 8.

Material examined

One specimen, Xincun, Hainan Island.

Measurements

See Table 1.

Distribution

Hainan Islands, Australia. Not previously recorded from the China Seas.

Remarks

The specimen agrees well with photographs (Kilburn manuscript) of the holotype. Although only the radula will confirm its generic position, its shell characters appear closer to several Ptychobela spp than to Inquisitor . Wells (1994) noted that the species was “known only from 154 to 200 m depth N. of Port Hedland, Western Australia ”. The present specimen was definitely collected in shallower water.
