FIGURE 14. Thoracic skeletal surface of anterior carapace. (A) C. kurrichalpongo MAGNT R24814 (Humpty Doo, NT) showing (a) the usual condition of peripheral 1 in sutural contact with costal 1 in Chelodina (Chelydera); (b) scar of the hyoplastron suture with costals 1 and 2 showing its long, clubbed shape in this species and (c) attachment rugosity for retrehans capitus collique muscles. (B) C. oblonga WAM R29362 (Shenton Park, WA) showing (a) the variable condition known to occur within Chelodina only in C. oblonga, and which exists in the lectotype, in which the nuchal and peripheral 2 meet in a short suture behind peripheral 1 excluding it from contact with costal 1 and (b) scar of the hyoplastron suture with costal 1 showing its broad shape with short medial taper.
