10 CHELONIA. 



The suture between the pectoral and abdominal plates straight ; fingers and 



toes broadly webbed Notochelys, p. 17. 



**** Pectoral plates forming a suture together ; lobes of the sternum immoveable ; 

 the bridge between the upper shell and sternum is broad and very convex, 

 and the suture between them is osseous ; head of moderate size ; tail short. 



Only the hind toes are moderately webbed Geoemyda, p. 18. 



Toes broadly webbed ; a broad suture between the third and fourth vertebral 



shields; claws strong £»«?/s, p. 21. 



The third and fourth vertebral shields are pointed at theii' junction ; claws 



of moderate size Pangshura, p. 33. 



Claws feeble Batagur, p. 37. 



***** Head very large, taU very long Platysternum, p. 42. 



MANOURIA, Gray. 



Thorax and sternum solid, entirely bony, united into an immoveable case ; 

 the upper shell depressed ; sternum concave in males, flat in females ; pec- 

 toral plates narrow, triangular, far apart, not forming a suture together. 

 Feet with the toes very distinct and with the hind toes webbed. Claws five 

 anteriorly and four posteriorly. 



Nothing is known about the habits of this Tortoise ; it appears to be an intermediate form 

 between the true Land Tortoises and the Terrapens.

Form. — Shell rather depressed, much broader than high, truncated anteriorly, of sub- 

 quadrangular shape, the lateral corners being somewhat prominent, and the lateral margins 

 between them nearly straight. Its greatest depth is a little more than the distance between 

 the axillary and inguinal incisions, and less than the width of the sternum between the front 

 incisions. The anterior and posterior margins of the shell are much reverted. The plates 

 are smooth and polished, each with its centre more or less deeply sunk in. The sternum is 

 obtusely pointed in front and deeply notched posteriorly; its width between the front 

 incisions is nearly equal to that between the hinder. 



Plates. — The areolae of the second, third, and fifth vertebral and of the second and third
