ISOPODAN AND TANAIDACEAN CRUSTACEA FROM SOUTHERN INDIAN OCEAN 313 between these two species and C. unicornis are readily apparent. The mostobvious is in the structure of the lateral pereional extensions—bifid in C. australis,single in C. unicornis and C. frigida. C. australis carries a single median dorsalspine on each of the pereional segments while in the present species, onlythe first pereional segment bears a strong dorsal horn (hence the specificname). Regarding the appendages, there is general agreement between those ofC. australis, well illustrated by Nordenstam (1933) and the present differences are apparent, particularly in the maxilliped, and first pereiopodof the male.
