TESTUDINID^E. 



419 



is pyriform, pointed in front, broadly rounded behind. Its length is 60 mm.; its greatest 

 breadth also is 60 mm. 



The hyoplastral bones join at the midline for a distance of 49 mm.; the hypoplastrals, a 

 distance of 70 mm.; the xiphiplastrals, a distance of 46 mm. The notch in the rear of the 

 plastron is 38 mm. wide. The hinder lobe has a length of 70 mm., and a width of 140 mm. 

 at the base. 



The gulars are, taken together, 58 mm. wide. They overlap on the entoplastron. The 

 humeral scutes are 40 mm. long on the midline; the pectorals, only 12 mm.; the abdominals, 

 86 mm.; the femorals, 40 mm.; the anals, 25 mm.

The outer surface of the plastral bones is somewhat sculptured along the lines of growth 

 of the scutes. There were large inguinal scutes and their areas are strongly imprest with the 

 growth lines. 



The present species comes from an earlier formation than that to which T. niobrarensis 

 is supposed to belong. The latter appears to differ in having a more projecting epiplastral lip. 

 What remains of the entoplastron indicates that this was relatively narrower and longer than 

 that of T. farri. 



From T. vaga, which it resembles, this species is distinguish! by the much shorter union 

 of the pectoral scutes at the midline, 12 mm., instead of 50 mm. There are other differences. 



T. osborniana has the union of the pectoral scutes still shorter than has T. farri. The 

 entoplastron is of a different shape and the vertebral scutes are less angular. 



This species is named in honor of Dr. M. A. Farr, of the department of paleontology in 

 Princeton University, Princeton, New Jersey.

The type of this species belongs to the American Museum of Natural History and bears 

 the catalog number 6135. It was found during the summer of 1906, by Mr. Albert Thomson 

 on Porcupine Creek, South Dakota. The beds in which it was found are the Lower Rosebud, 

 a part of the Lower Miocene. The shell only is present and of this the costals of the left side 

 behind the fifth are missing, also the peripherals behind the left seventh, the pygal, the right 

 eleventh peripheral, and the ultimate and penultimate suprapygals. 



The length of the carapace (plate 70, fig. i) was very close 10320 mm. The extreme width 

 is 255 mm. The shell was high and vaulted and apparently highest toward the rear. The out-
