scute on each side of the nuchal scute. It is 2-J- inches long in the 

 median line, 2J inches hroad at the anterior lateral angle (where it 

 meets the first marginal and first costal scutes), and 1-J inch broad 

 along the sinuous transverse posterior line (in which it meets the 

 second neural scute). Like all the other scutal areas, both of the 

 carapace and plastron, it is marked with subparallel impressed con- 

 centric lines indicative of the intermittent growths of the scutes. 

 These lines are least distinct on the posterior border. 



The first vertebral scute extends transversely beyond the nuchal 

 plate (which is 2| inches broad) so as to impress the angles of the

marginal plates. The scutal area is convex in length as well as 

 in width ; its posterior border impresses the first neural plate at 

 less than half an inch in advance of its posterior sutural border. 



The second vertebral scute (v 2) is nearly square, being about 2| 

 inches long and nearly 2| inches broad. The two pairs of sides, 

 which are somewhat sinuous, are subparallel ; and the area is con- 

 vex in length as well as in width. Its anterior and posterior borders 

 cross the first and third neural plates, while its lateral borders cross 

 the first, second, and third pairs of costal plates.
