Habitat in Brasilia, (v. v. Hort. Zoo)., et t. Mus. Brit., 

 Col. Chirurg., D. Bell. &c.) 



A large species, sometimes 24 inches long, (v. Mus. Col. 

 Surg.) The shields are sometimes worn smooth in the adult 

 animal, and the sides of the shell are often very much con- 

 tracted, the areola is small, and rarely exceeds three quarters 

 of an inch in width. The animal is more or less red or 

 yellow spotted, and the tail varies in length, probably in the 

 different sexes ; it may prove only a variety of the next.

 Hab. in Brasilia, (v. v. Hort., Bell, et nost., t. Mus. D. Bell.) 

 This species dilFers from the former in being more depressed 



and less contracted on the sides, in the areolae of the shields 



being larger, rarely less than one inch wide, and the posterior 



extremity of the sternum being acutely lobed.

The shell light, probably not full grown, the front margin
