description and more complete illustrations of material from Bass Strait are similarly unmistakable. His habitus drawing is reproduced here. The redescription above is limited to the body armature and to those features important in differentiation of antarcturid genera: antenna, pereopodal dactyli, male pleopods 1 and 2, female sternite 8 and the uropod. Both Whitelegge and Hale illustrated and described ovigerous females. The diagnostic ornamentation can be discerned in a reduced form in specimens of all sizes.
