Two new species of Aporocidaris, A. eltaniana and A. usarpi, and one new species of Notocidaris, N. lanceolata, are described from material collected during United States Antarctic Research Program expeditions in the 1960's. All three species occur in the bathyal zone near or south of the Subantarctic Convergence. Gonopore sizes and peristomial morphology suggest that these species are sexually dimorphic and that the females can brood direct-developing young. However, only one of the Aporocinaris species was found to harbor embryos on the peristomial membrane.
