Fam. TESTUDINID.E. 



(Supplement, p. 3.) 



The knowledge of the animal of the genus Scapia ren- 

 ders it desirable to make an alteration in the arrangement 

 of the genera of this family which is given in the ' Supple- 

 ment to the Catalogue of Shield Reptiles,' the alteration 

 being more in the characters given to the two chief sections 

 than in the sections themselves, which remain nearly the 

 same, except in removing Scctjiia to the second section. 



Synopsis of the Genera . 



Section I. Head short, broad. The two central hinder marginal 

 plates united into a broad caudal plate. Sternal shields 12, 

 arranged in pairs on each side. Pectoral plates large, like 

 the others. Rarely abnormal specimens occur in which the 

 two united caudal plates are marked by a centred groove ; and 

 more rarely they occur separate. 



A. The nostrils in a square fleshy nose between the upper edge of 

 the beak and the frontal plates ; thorax solid. Tlie inguinal 

 plates moderate or wanting. 



* The alveolar surface of both upper and lower jaws ivith a distinct 

 submargiiial groove. Testudinina. 



l. Testudo. Gular plates separate. Claws 5. 4. Alveolar plate 

 with two ridges. Lower jaw narrow, witli a deep groove 



extending the whole length of the edge ; front of upper 

 jaw with a central notch and two deep prominences. 



2. Peltastes. Gular plates separate. Claws 5.4. Alveolar 



plate with an indistinct ridge. 



3. Testudinella. Gular plates separate. Claws 4.4. 



4. Pyxis. Gular plates separate. The front lobe of the sternum 



mobile. 



5. Cherstna. Gular plates united and produced. 



** The alveolar surface of the upper Jaw with a distinct submar- 

 yiual ridge, of the lower jaw simple. Iioniopina. 



6. Homopus. 



B. Tlte inguinal plates very large; the nostrils in a notch on each 

 side of the middle of the upper edge of the beak : thorax, 

 hinder part mobile. Kinixyina. 



7. Kinixys. 



Section II. Head oblong, elongate. The two central hinder mar- 

 ginal plates on the tail separate, as in the generality of the 

 Freshwater Tortoises and the Turtles. Manourina. 



8. Manouria. Sternal shields 10, arranged in five pairs. The 



two pectoral plates small, short, triangular on the hinder 

 side of the axilla. 



9. Scapia. Sternal plates 12, regularly arranged in pairs ou 



each side of the central line.
