the cfiitra rapidly eloiifjatc and the processes become rudimentary. Tlie distal end of 
th(‘ tail is (•omi)()s(>d of numerous very slender joints. Strong chevron bones are found 
under some of the anterior vertebrae. 
Tjie Ribs. — The ribs are like those of the bears ; the anterior ones, especially the 
first, are remarkably .short and hat; about the 7th they become slender and oval 
in section and from the 9tli decrease in length. Heads and tubercles are well de- 
velojKjd except on the last two or three, when the tubercles become rudimentary. The 
la.st rib is very .slender. 
The .Stekxum. — Of this bone only one complete and parts of two other segments 
are preserved, enough to show that the sternum was comparatively broad and flat 
slightly concave on the upper surface and convex on the lower, very much as in Arc- 
tictiM. 'fhe .segments are also of rather unusual length. 
The Fohe-Limb. — The scapula is in general much like that of Hyaena and the 
cats. 'I'lie glenoid cavity is deeply concave antero-posteriorly, but rather .shallow 
transversely: the coracoid is very small. The neck is constricted and very narrow, 
and the coraco-scapular notch correspondingly deep. The coracoid border is curved 
Hi»wards and backwards from the edge of the notch, enclosing a large prescapular 
fossji. 'fhe supni-wai>ular border is thickened, rugose, nearly straight, and inclined 
somewhat downwards. The glenoid border is also nearly straight, but with an un- 
usual oblifpiity. The siiine is jn-ominent, ending in a stout curved acromion which

nearly .upud extent. Compared with the other limb-bones, the scapula is very loim, 
longiT than the radius, which is a rare proportion among the Carnivora.
