Hallaxa gilva n. sp. is described and illustrated. It is distinguished from four congeners by: colour, uniform pale fawn with scattered opaque white spots; notal (mantle) tubercles, small, conical, evenly and sparsely distributed; radular teeth, first or innermost lateral larger than rest, trapezoidal almost triangular with three large denticles, innermost of these being the cusp, at tip, rest of laterals grading outwards from elongate trapezoidal to rectangular with up to five terminal denticles (innermost the cusp) to triangular (outermost tooth) with denticle (cusp) at tip and a row of up to eight small denticles down upper half of outer edge. Presence of oral tentacles (rectangular and grooved) is not regarded as a specific characteristic. The separation of Hallaxa and Actinocyclus is sustained, and the relationship of these two genera, as a family or subfamily, to the chromodorids is discussed.
