306 Mr. Bell on the Box Tortoises, 



the nostril across the orbit to the back part of the head, wh ere 

 they unite. The nostrils anteriour, situated close together. Beak 

 sub-elongate. The neck very long, cinereous above, yellow 

 beneath. The fore feet have five long and sharp claws, the 

 hinder ones four. Tail rather long and slender, and without any 

 horny appendage at the extremity. The shell oval, broader be- 

 hind, the margin slightly indented. The back carinated. The 

 plates very thin, slightly wrinkled, and striated towards their 

 margin. Those of the spine very slightly imbricated. The mar- 

 ginal plates, which are 25 in number, are of considerable propor- 

 tional size, and the posteriour angle of each a little projecting, so 

 as to give an indented outline to the circumference of the shell. 

 The pectoral plates are twelve in number, and nearly smooth. 

 The hinder lobe of the sternum is flat, horizontal, emarginate, 

 ftnd placed with its edge so near to the upper shell as barely to 

 allow of the passage of the slender tail and flattened legs. The 

 anteriour valve is very entire, and capable of completely closing 

 that part of the shell. The general colour is a light dull yellow, 

 intermixed with reddish and black markings. The carina is black, 

 and there is on each side, at the distance of about three quarters 

 of an inch, a black longitudinal band running parallel with it 

 down the back, which gives the shell the appearance of being 

 tricarinated. The prevailing colour of the sternum is black, with 

 a light edge ; and towards the centre it assumes also a light 

 ground, with distinct black radiations from the area of each plate.
