TESTUDINIDA. 443 
The pelvis (figs. 590 a, ) is represented by the greater portion of the left side. The lateral 
process of the pubis is rather short, flat, and broad and rounded at the end. The tuber ischii 
is rather slender and pointed. 
No. 1325 of the American Museum is likewise a part of the Cope collection. It was a 
larger animal than the type just described. The length of the plastron is 615 mm. and its 
width to the outer borders of the bridge peripherals could not have been less than 555 mm. 
The width of the carapace at the inguinal notches was 600 mm. Almost the whole of the 
plastron is present; also considerable parts of the costals and neurals in a fragmentary state; 
and the greater part of the rim of the carapace, of the shoulder-girdle, of the pelvis, and of the 
limbs. ‘The plastron differs from that of the type principally in the size and form of the 
anterior lip. This (fig. 591) is relatively broader, with its sides less converging, less truncate 
in front, and less cari- 
nated above. Since, how- 
ever, the two individuals 
are so closely alike in all 
other respects and there 
seems to be a good deal 
of variation in the form 
of the lip among the var- 
ious specimens, there is 
apparently no_ sufhcient 
reason for regarding No. 
1325 as belonging to a 
different species. The 
width of the lipat the base 
is 184 mm. Where the 
curve of the sides into the 
anterior border 1s made 
the width is 150 mm. 
Instead of being slightly 
notcht in front, the ante- 
rior border is broadly 
rounded. From side to 
side the upper surface is 
evenly convex. Figs. 592, 
593 represent sections of 
the lip. 
The entoplastron is 163 
mm. long and 200 mm. 
Fics. 594 AND 595.—Testudo orthopygia. Left humerus. 3. wide. The humero-pec- 
No. 1325 A. M. N. H. toral sulcus passes just 
behind its hinder border. 
The plastron is rather 
deeply concave in front of the hinder lobe, a condition which indicates that the individual 
was a male. Fig. 2 of plate 78 gives a view of the rear of the shell seen from below. 
Of the anterior portion of che carapace only peripherals 1, 2, and 3 are present. They 
differ in no important respect from the corresponding elements of the type. Almost the w hole 
of the posterior rim is present, the pygal and most of the peripherals being complete. At the 
midline the hinder edge of the carapace falls about 120 mm. behind the plastron. The upper 
portion of the peripherals i is nearly perpendicular, but the lower portion is considerably flared 
outward. The eighth peripheral has a height of 160 mm.; the eleventh, of 120 mm. The 
second suprapygal i is present, of rhombic fatten, and about 110 mm. from side to side. Its 
lower half is placed in a notch in the pygal. The sulcus behind the fifth vertebral scute crosses 
it horizontally in the middle. Costals and neurals too fragmentary to justify description. 
The left scapula is present in No. 1325. The length of the bone from the superior extremity 
to the middle of the glenoid fossa is 180 mm.; from the latter point to the extre mity of the
