70 ADDITIONS AND CORRECTIONS. 



The lateral margin convex, rounded, v/ithout any prominent 

 ridge, perhaps rounded by the shell being old and worn. 

 The hinder margin evenly rounded, slightly reflexed, and the 

 edge scolloped by the centre of the marginal plates being 

 slightly produced. The shields pale yellow, rather convex, 

 deeply concentrically lined ; the lines become more shallow 

 and closer together as they approach the margin. The areolae 

 moderate ; in thediscal plate central, and in the marginal plates 

 sub-central, being rather near the hinder edge. The fourth 

 and fifth vertebral plates the most convex, and rather promi- 

 nent in the centre. Marginal plates 24 ; the nuchal one is 

 long and narrow, the caudal one is about one-third broader 

 than the others of the hinder margin. The sternum flat, 

 rather bent up in front and rounded, ascending on the sides, 

 produced and truncated before and behind. The sides of the 

 anterior and posterior lobes slightly produced and rounded. 

 The axillary plate small, the inguinal plates large. Length 

 of shell 8 inches, of sterruim 7^ inches ; breadth at hinder 

 joint 6, and over the axillary plates 5 inches. 



This species is intermediate between the two before 

 described ; it agrees with K. Homeana, in having the nuchal 

 plate, and with K. denticulata in the centre of the fourth and 

 fifth vertebral plate being convex. It differs from both in 

 the margin not being expanded and denticulated, and in the 

 side edges of the front lobe of the sternum not being pro- 

 duced and wing-like, but this may be occasioned by the shell 

 being much worn. 



The head with small flat scales and two larger plates 

 between the eyes over the nostrils, and one behind them. 

 The jaws are nearly entire, the fore feet are covered in 

 front with large unequal convex scales, and have five blunt 

 subequal claws. The hind feet are covered with rather thin 

 scales, they have four blunt claws, and large blunt claw-like 

 scales at the heel. The tail is short and thick, conical, 

 scarcely longer than the edge of the shell.
