12. TESTTIDO ANGULATA, Bimeril. 



Tab. XIX. 



Chersina angiilata, Gray, Cat. Sli. Rept. Suppl. p. 13. 



Hab. South Africa. 



This species is at once known by its having only a single, narrow, produced gular plate in front of 

 the sternum, which forms a ledge for the defence of the throat. 



13. TESTTIDO SIGNATA, Walbmm. 



Tab. XX. 



Homopus signatus. Gray, Cat. Sh. Rept. Suppl. p. 13. 



Hab. South Africa. 



This species has only four claws on its front feet. The vertebral and costal plates are all abovxt as 

 broad as long, and the hinder marginal plates are angular and revolute. 



14. TESTTIDO AREOLATA, TJmnherg. 

 Tab. XXI. 

 SomojMs areolatus, Gray, Cat. Sh. Rept. Suppl. p. 13. 

 Hab. South Africa ; Madagascar. 



The front legs are covered with very large scales, and have only four claws on the fore feet ; the 

 first vertebral and costal plates are much longer than broad, and the others much broader than iong, 

 the lateral margin revolute. 



Mr. Bell says : — " This species is easily familiarized. I have repeatedly had them so tame as to 

 take food readily from the hand, and even to eat from one hand when held in the other." 



15. TERRAPENE CLATISA, Merrem. 



Tab. XXII. 



Cistudo Carolina, Gray, Cat. Sh. Rept. Suppl. p. 19. 



Hab. North America, from Hudson's Bay to the Gulf of Florida. 



This is one of the most variable species in its coloration. Bell divided it into three species ; and 

 Agassiz has more recently done the same. There is an allied species which has only three claws on
