TESTUDINID&. 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.

Fics. 548 AND 549.—Testudo farrt. Carapace and plastron of type: <4. 
548. Anterior half of carapace. 549. Plastron. 
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 J. niobrarensts 
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 7. farrz. 
From T. vaga, which it resembles, this species is distinguisht 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. farrt. 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. 1) was very close to 320 mm. The extreme width 
is 255mm. The shell was high and vaulted and apparently highest toward the rear. The out-
