DENTICULATED TORTOISE. 



Testudo Denticulata. T. pedihns snbdigitatiSy testa, orhkulato' 

 cordata, margine eroso. Lin. Si/st. Nat. Gmel.p. 1043. 



Tortoise with subdigitated feet, and orbicularly-cordatcd shell 

 with denticulated marginal segments. 



The shell of this species is of a pale yellowish- 

 brown colour, measuring about four inches in 

 length, and about three in breadth, and is covered 

 on the disk by broad hexagonal and pentagonal 

 scutella, which are of a flattened form, Avith a large 

 distinct area or middle space, granulated by small 

 tubercles, the remainder marked by five lines or 

 furrows. The edge of the shell consists of twenty- 

 three pieces, all of which project in a serrated 

 manner round the outline, those toward the ends 

 being terminated by a sort of abrupt denticulated 

 process, as shewn in the annexed engraving, 

 which is taken from a specimen in the Leverian 

 Museum. The convexity of the shell is mode- 

 rate, and it appears to be a terrestrial species. It 

 is supposed to be a native of North America. The 

 feet in the Gmelinian edition of the Systema Na- 

 turse are said to be without distinct toes, and the 

 tail short.
