The head in lateral view has a distinct constriction opposite to the oral part.
Postero-lateral thoracic margin rounded in lateral view, and in dorsal view obtusely pointed.
Abdominal segment 5-segmented; segments and caudal rami in the proportional lengths 19 : 16 : 15 : 13 : 6+31 = 100.

Remarks : The author had obtained several specimens of robustus both female and male from the Izu region; on comparing the present antarctic male with that of robustus it is clearly distinct from robustus. They differ each other in the shape of P5, the 3rd segment of the right P5 of farrani is different in the proportional length from that of robustus, and also in the characteristic long spine on the inner margin of the exopodal segment of the left leg.

H. farrani ressemble fortement à H. robustus Farran, 1908. En 1965, Vervoort affirme que ces deux espèces sont différentes ''les segments abdominaux sont garnis distalement d'une frange de spinules chez H. farrani'' tandis que ceux chez H. robustus sont à peu près nus''. Or, les segments chez H. robustus figurés par Tanaka (1964) portent une frange de spinules.
Espèce caractéristique des eaux purement antarctiques. Ses effectifs deviennent très faible au nord de la convergence antractique. Dans le Paxifique sud-est, elle remonte jusq'au 40°46' Sud (Bjornberg, 1973). Espèce des eaux froides qui supporte des températures allant de - 0,72°C à + 1,15°C.
