BAENA HEBRAICA. Cope. 
Established on a large and nearly complete fossilized tortoise, which 
lacks the posterior lobe of the plastron, and a corresponding part of the 
carapace. The component elements are codssified. 
The costal seuta are very wide, excepting the first pair, whose posterior 
margin is sigmoidally flexed. The anterior vertebral is concave behind, 
and has convex lateral margins. The marginal scuta in front are very 
narrow, but the fourth on each side is suddenly widened in front to meet 
the suture between the first and second costal scuta. The sutures are all 
perfectly regular. There are only four inframarginal scuta, of which the 
t, forming, with the third, an angle project- 
second from front is the large 
ing inwards. 
The carapace and plastron are smooth, excepting in the lines of the 
sutures of the costal bones. In this position-there is, in each case, a series 
of short pit-like grooves parallel to each other, and transverse to the axis 
of the bone, forming figures like some Hebrew letters, the Greek //, etc. 
The borders of the carapace are obtuse, and the general form is almost 
round. The diameter is almost eighteen inches. 
This species may only be compared with the B. wndata, Leidy, with 
which it agrees in having the humeral scuta crowded to the front of the 
plastron, and haying a common centre with the gulars, which they little 
exceed in size. It differs in having four instead of five inframarginals, 
regular sutures, a differently formed first costal, wider lateral marginals, 
| and in the smooth carapace with the peculiar sculpture mentioned. 
TESTUDO HADRIANA. Cope. Spec. nov. 
Indicated by two individuals, one nearly perfect, the other chiefly rep- 
resented by a complete plastron. 
This proves the existence of a very massive species of the terrestrial 
genus Testudo. The plastron presents a short wide lip in front, which is 
turned outwards, forming a strong angle with the plane of the upturned 
front of the lobe. This lobe is bordered by a thickening of the upper 
surface, which cuts off the basin from the lip, as a high ridge. The pos- 
terior lobe is deeply bifureate, each post-abdominal projecting as a trian- 
gle. There is a notch at the outer angle of the femoral scute. The 
\ hyposternal bone is ereatly thickened within the margin above, and an 
elevated ridge bounds the basin of the plastron behind, as before. The 
middle of the plastron is thin. 
The carapace is without marked keel or serrations. It is remarkable 
for its expanded and truncate anterior outline, which is nearly straight 
between two lateral obtuse angles. 
Length carapace, M. .750 = 29 inches; width, .630. 
The marginal scuta are narrow, and there is a large nuchal plate. 
Same locality as the last.
