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., 11, p. 29) might belong to 
his earlier publisht Ewpachemys obtusa, which he referred to mistakenly under the name 
Eu pac he PI VS rugoOsUS. 
In the eellecuon of the U. S. National Museum at Washington there is a large peripheral 
which was collected by Dr. W. H. Dall at Caloosahatchie, Blorida, 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 a mid- 
line, and a width close to 475 mm. at the base. Dr. L eidy 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
