The specimen figured by Gunther as G. Oldhami was obtained alive by 

 myself near Mergui, and is merely the adult of G. orbiculata, Bell. The or- 

 bicular form of the shell, as well as the strongly toothed margins, charac- 

 terise young and half grown shells, disappearing as the animal becomes 

 full grown. Both Bell and Gunther describe the sternum without any 

 cross joint, such as occurs in Cuora, but occasionally the bony trans- 

 verse suture remains permanently unanchylosed, causing a false joint 

 simulating the true cartilaginous joint of Cuora, In a specimen in my 

 possession the motion is pretty free, though the suture is covered by 

 the ends of the abdominal plates. In very young shells this transverse 

 joint is imperceptible ; in half grown individuals it is well distinguish- 

 able, and in adults it is not unfrequently conspicuously marked external- 

 ly by a sort of carious fossa across the abdominal plates, resulting, no 

 doubt, from the mobility of the bony suture beneath.
