Remarks. Material examined here extends the distribution of C. circe   north, from Tasmania to the Australian mainland in South Australia and New South Wales.

Ceradocus circe Lowry & Springthorpe, 2005   has the same dominant gnathopod 2 palm sculpting as C. chiltoni Sheard, 1939   and C. chevreuxi Sheard, 1939   , the presence of two pair of lateral setae on the telson   distinguishes C. chiltoni   , however C. circe   and C. chevreuxi   have little character variation. Material of these species are widely distributed ( Sheard, 1939), C. chiltoni   is known from New Zealand (Auckland, Akaroa and Great Barrier Island), C. chevreuxi   from Gambier and Tuamotu Archipelago (Serat, 1904),? Fiji, Marshall Islands, British Solomon Islands, and Philippines ( Schellenberg 1938), while C. circe   has been recorded from temperate Australian waters. Further study of these collections is required to better understand this morphologically close group.

Distribution. Australia. New South Wales: North West Solitary Island, Port Stephens, Bermagui (current study). Tasmania: Circular Head; eastern slope of Bass Strait; Sheppards Point; Bicheno; Recherche Bay ( Chilton 1921; Lowry & Springthorpe 2005; current study).
