d. Young, solid ; shell only, 4 inches. Cape of Good Hope. Pre-

4. Kinixys, Bell. Cinixys, Wagler. 



Thorax convex, hinder lobe becoming mobile, with a carious 

 suture. Sternum solid ; sternal plates 12 ; gular pair produced 

 and separate ; inguinal plates very large. Claws 5-4, outer front 

 one very small. 



In the young, the dorsal suture is scarcely observable, but then 

 the genus can be distinguished by the large size of the inguinal 

 plates, the suture becomes more observable as the animal increases 

 in age; unlike the box tortoises, where the moveable lobes of the 

 sternum often become anchylosed in the older specimens. Cuvier 

 only having seen one specimen (Reg. An. ii. 10), considered this 

 structure as an accidental deformity, and Wagler by mistake says 

 it is the front part that is moveable. 



* Fifth vertebral plate produced.
