14 CHERSINA. 



adumbratis, areolis nigricantibus depressis, scutellis margi- 

 nalibus 26 leviter dentatis, nuchali angustissimo. 



Test, signata, Walb. Chelon., ii f. cop. Schoepf. t. 28 ; 

 Test, denticulata, Far. Gmel. 



Habitat in Africa, (v. t. Mus. Bell, et Par.) 

 Test. Cafra, Daud. (v. Mus. Par.) is probably a mon- 

 strosity of this -species, with 1 5 dorsal plates ; and Test. 

 Juvencella. Daud. (v. t. Mus. Par.) seems only a variety with 

 convex scutella ; but it is impossible to determine it with 

 accuracy, as all the three specimens in the Paris Museum 

 are in very bad condition. There are also two specimens in 

 the same collection, marked as a variety, with 22 marginal 

 plates, said to come from Carolina. 



Species Fossiles, Cuv. Os. Fos. v. 244. 



Testudo Lamanonii. Tortue des environs d'Aix, Cuv. 

 Os. Fos. V. 244. Lamanon Jour. Phys. xvi. t. 3, cop. Cuv. 

 Os. Fos. t. 13, f. 9—11. 



Fossil, Gypsum Rock Aix, considered as fossil human 

 heads ; breadth six, hei-ht seven inches. 



Test. Neraudii, Tortue de L' Isle de France. Cuv. Os. 

 Fos. V. 248. t. 15, f. 17, (humerus) f. 18 (tibia). 



Fossil, in the volcanic deposits of the Isle of France. 



Testudo squamata, Daud., from Bontius n. 82, is certainly 

 a species of Manis, of which lUiger has formed a genus, under 

 the name of Pamphractus. 



Gen. 2. CHERSINA, (Chersina.) 



Scutum dorsale sternaleque solida ; scutella sterni 11, 

 gularia connata. 



This genus only differs from the other Land Tortoises, in 

 the gular or anterior pair of sternal shields being united 

 into a single plate, and produced in front of the shell. It 

 agrees in this character with the genus Kmosternon, amongst 

 the Terrapins, or Emydes. Merrem gives the above generic 

 name to all the Land Tortoises, keeping that of Testudo for 

 the family. I have restricted it to the species with the 

 above character.
