is a little less than the width of the centrum; in TJ. concolor it is a little 

 greater. (2) The posterior edge of the neural spine is narrow and simple; 

 in U. concolor it is wide and grooved. (3) There is no reverted process 

 near the base of the diapophysis, as in U. concolor. (4) The metapophyses 

 are more compressed, and rise higher than in U. concolor. As in the puma, 

 there are no anapophyses.

The differences between this vertebra and the corresponding one of 

 Uncia concolor are nearly those which distinguish it from the lion, leopard, 

 and cheetah, with the following exceptions: In the lion the neural spine is 

 thin behind, and the metapophyses thin and elevated, as in A. debilis. In 

 the leopard the angle of the transverse process is not produced, and is more 

 distal. The diapophysis in the cheetah is quite as in A. debilis, slender 

 and without posterior angle. 



Portions of the scapula and of the fore and hind limbs of this specimen 



are represented on Plate LXXIw, figs. 9-1 G, The glenoid cavity of the 



former narrows forwards to a subacute apex, which is not truncate, as in 



the panther. The coracoid hook, if it were present (the specimen is injured), 



originated farther above this ape.x than in the panther, leopard, or common 



cat. The characters may be compared with those of the recent cats, as 



follows: 



TJncialeo. Coracoid nulimental; anterior tuberosity acute; posterior border of neck 



truncate; adjacent angle-ridge not continued. 

 Arcludurus debilis. Anterior tuberosity acute; posterior bolder truncate and rugose 



for insertions; no adjacent angle-ridge. 

 Uncia concolor. Coracoid distinct; anterior tuberosity truncate; posterior border of 



necli truncate and rugose for insertions. 

 Unda pardus. Coracoid distinct; anterior tuberosity acute; posterior edge not trun- 

 cate; no adjacent angle-ridge. 

 Cyncehtrus jitbatus. Coracoid distinct; anterior tuberosity acute; posterior edge not 



truncate; adjacent angle-ridge not defined. 

 ^elis domestica. Coracoid present, not separated by notch, and continuous with anterior 



tuberosity; posterior edge openly grooved on account of adjacent posterior 



angle-ridge.
