civets. The manubrium is long, more so than in Canis, as well as narrower and more 
compressed. The first pair of ribs is attached to a pair of wing-like processes, which 
are unusually far from the second pair. In front of these processes the bone is com- 
pressed and yery narrow. For much of its length the manubrium possesses a ventral 
keel. The segments of the mesosternum, so far as they are preserved in the various 
specimens, are more elongate, more slender and depressed and more contracted in the 
middle than in the recent Canide.

The scapula is quite remarkable and is in character rather yiyerrine or raccoon-like 
than canine. The shoulder blade is rather low and broad and is divided by the spine 
into pre- and postscapular fossee of nearly equal breadth, while in the modern dogs the 
scapula is high, narrow and of subquadrate shape, and has the spine so placed as to 
make the postscapular fossa much the larger of the two. The glenoid cavity is moder- 
ately concave, and is elongate antero-posteriorly, but narrow transversely. The coracoid
