摘要：

A new species of the genus Parachiton, I! hodgsoni n.sp., which inhabits shallow water off the South African coast, is described. The radula is unusual for the genus Parachiton. It consists of about 160 transverse rows of very small mature teeth of which the major lateral teeth have very narrow tridentate cusps. The intermediate valves are granulose with the granules arranged in widely spaced, longitudinal rows on the central area of the valves. There are 20-31 longitudinal rows on the central areas of the intermediate valves. Variability in the morphology of the tail valve is shown.
