marginal scutes which occupied the bone. In fig. 615, which represents the posterior end of the 

 peripheral, the outer surface is toward the left hand. 



In the collection of turtle remains from Peace Creek, Florida, Dr. Leidy found a thick and 

 rounded peripheral which he thought (Trans. Wagner Free Inst., II, p. 29) might belong to 

 his earlier pubhsht Eupachemys obtusa, which he referred to mistakenly under the name 

 Kiipachemys rugosus. 



In the collection of the U. S. National Museum at Washington there is a large peripheral 

 which was collected by Dr. W. H. Dall at Caloosahatchie, Florida. It has a length of 145 mm. 

 The costal border is broken off. The free border is obtuse. The greatest thickness is 37 mm. 

 It is possible that it belongs to the present species.

The materials described by Dr. Leidy under the above name consisted of a number of 

 fragments of one individual, mingled with a few fragments of the shells of two others. These 

 remains indicated a tortoise whose carapace measured about 1520 mm. in length. The 

 specimens are now in the U. S. National Museum and have the number 986. They were 

 discovered in the Peace Creek beds, at Arcadia, Florida. As the type those bones must be 

 taken which were figured by Dr. Leidy. These are the greater portion of the right epiplastron,

wrongly mentioned by Leidy as the left, a portion of the right hyoplastron, the thickened 

 borders of the hinder lobe of the plastron, the left femur, and the left tibia. 



The anterior lobe of the plastron (fig. 616) had a length of 280 mm., measured at the mid- 

 line, and a width close to 475 mm. at the base. Dr. Leidy gives the width as 520 mm.; but he 

 measures outward to the middle of the axillary notch. From the base the lobe narrows rapidly 

 to the front, where the width is about 80 mm. The lip does not project beyond the general 

 curvature of the lobe, but it does project beyond the ends of the gulo-humeral sulci. From the
