above the condyles. The great trochanter is large and retro- 

 verted, rising above the head, with two prominences rising from 

 it, one on top, the other back. The digital fossa is wide and 

 deep, penetrating far into the great trochanter. The second 

 trochanter is a small rounded ridge ; the thi^d trochanter is 

 large and prominent, curving slightly forward. The condyles 

 are long and narrow, projecting very far back, and are separ- 

 ated by a wide and deep popliteal groove. From the ex- 

 ternal condyle a low ridge runs obliquely, forming the upper 

 border of the shallow popliteal space. The trochleas are long, 

 very convex, deeply grooved, and symmetrical.

The tibia (Plate IX. Fig., 3) is very long and heavy, with 

 broad proximal articular face, the inner borders of which are 

 prolonged upward and separated by a groove. 



The shaft at the tuberosity is subtriangular, with strongly 

 concave sides. The tuberosity is prominent, with a deep pit 

 on its upper surface for the insertion of the ligament of the 

 patella. The shaft below becomes sub-cylindrical, and de- 

 creases regularly in size downward. Its curvature is for- 

 ward. The distal articular face is divided by a smooth ridge 

 into two deep facets. The malleolus is long. 



The fibula (Plate IX., Fig. 2) is distinct, straight, and very 

 slender. The distal end is but slightly expanded, and is 

 strongly marked by a vertical groove externally. The proxi- 

 mal end articulates with the overhanging portion of the 

 proximal face of the tibia.
