ORDER CHELONIA. 67 



native of Jamaica, as the Hicatee tortoise mentioned by 

 Brown, seems to agree pretty well with it in characters and- 

 size, and by no means so with the geometrical tortoise. 

 Daudin, however, considers this tortoise of Brown to belong 

 to a variety of another species, the marginata. 



The Areolated tortoise (T. Areolata). The individual 

 of this species, figured by SchcepfF, in his Natural History 

 of Tortoises, was brought from the East Indies by Thun- 

 berg. Seba, on the other hand, has figured another indi- 

 vidual, which he names the land tortoise of Brazil. The 

 length of this animal is only three or four inches. The cara- 

 pace is oblong, a little more narrowed in the front, scarcely 

 indented at the top of the neck, and moderately convex. 



The disk is covered with thirteen plates, more or less 

 square or sexangular, moderately raised, and with their 

 sutures depressed. The edge of these plates is surrounded 

 by some concentric striae. The areolae, or central parts, are 

 smooth on their edges, and have their centre slightly svmk in, 

 and punctated roughly. On the centre of the areola of the 

 two anterior vertebral plates, there is a small projection dis- 

 posed length-wise, which is either effaced or non-existent on 

 the other plates The centre of the areolae is yellow, the 

 edges white, and the rest of the plates of a dirty bay. 



The marginal plates are square, nearly of an equal length, 

 and four and twenty in number. The marginal collar-plate 

 is small, and more narrow, while that which is placed 

 above the tail has a wider form than the others, and a little 

 furrow on the middle, which makes it appear almost double. 

 These plates are of the same colour as the disk, and are 

 separated from it by a sufficiently well-marked furrow. 



The plastron, or breast-plate, is yellowish and flat, trun- 

 cated, and scarcely notched in front, but marked with a sin- 

 gular notch behind, and covered with twelve scaly plates, 

 which are surrovmded by some brownish furrows.
