 Small Mud Tortoise. Edw. 287- 



THIS is one of the smaller Tortoises, the shell 

 measuring three or four inches in length when ap- 

 parently full grown. Its form is oval, its convex- 

 ity moderate, its surface smooth, and its colour 

 brown : the middle range of dorsal pieces are of a 

 longer form than in other Tortoises, and are so 

 placed as to lap over each other at the tips, which 

 are slightly emarginated : the uppermost piece is 

 of a triangular shape : the two upper side-pieces 

 irregularly or obscurely quadrangular, and the re- 

 maining ones pentangular: the marginal pieces 

 are twenty-three in number, the upper or join- 

 ing piece being very small : the edges of the shell 

 are tinged with dull yellow : the lower shell also 

 is of a yellowish colour, tinged with brown round 

 the v commissures or junctures of the pieces, and 

 is constituted nearly on the same plan as in the 

 close tortoise, the upper and lower division being 

 moveable in such a manner as to enable the ani- 

 mal to conceal itself almost entirely by shutting
