Baena hebraica. Cope. 



Established on a large and nearly complete fossilized tortoise, which 

 acks the posterior lobe of the plastron, and a corresponding part of the 

 carapace. The component elements are coossified. 



The costal scuta 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 

 second from front is the largest, forming, with the third, an angle project- 

 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. undata, Leidy, with 

 which it agrees in having the humeral scuta crowded to the front of the 

 plastron, and having a common centre with the gulars, which they little 

 exceed in size. It differs in having four instead of five inframarginals, 

 a differently formed first costal, toider lateral marginals, and in the smooth 

 carapace with the peculiar sculpture mentioned. 



Testtjdo hadriana. Cope, spec. nov. 



Indicated by two individuals, one nearly perfect, the other chiefly re- 

 presented 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 bifurcate, each post-abdominal projecting as a trian- 

 gle. There is a notch at the outer angle of the femoral scute. The 

 hyposternal bone is greatly 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 ai'e narrow, and there is a large nuchal plate. 



Same locality as the last.
