tal articular extremity is impressed by* l.§ trochlea?, the outer being com- 

 pleted by the fibula. The posterior tuberosity is more nearly median than 

 usual, hence the inner margin of the inner trochlea is low posteriorly, 

 and the inner malleolus has a considerable beveled inferior margin. The 

 fibula has a slender shaft, but little compressed. The head is expanded 

 fore and aft, and the malleolus is quite stout.

Both hind feet are perfectly preserved. The calcaneum is rather elon- 

 gate and compressed, the lower face truncate with two longitudinal 

 bounding ridges, the outer of which is discontinued before reaching the 

 heel. The surface between them is striate grooved. The outer face is 

 slightly concave. The astragaline facets are much expanded inwards ; 

 the outer is transverse and strongly convex, and separated by a groove 

 from the inner, which is longitudinal and nearly plane. The posterior 

 edge of this, and convexity of the outer facets are received into a trans- 

 verse groove of the posterior part of the lower face of the astragalus. 

 The cuboid facet is diagonal and is bounded within by a third narrow 

 facet for the astragalus. The astragalus has a strongly convex deeply 

 grooved trochlea ; the convexity extends over 158°. The trochlea is 

 nearly in the vertical, a little oblique to the longitudinal axis of the foot. 

 The exterior malleolar facet is well marked and bounds a lateral fossa 

 above. The neck of the astragalus is broad and not contracted, but not 

 wider than the trochlea. Its navicular facet is wide and concave, the 

 cuboid narrow, with a long angle behind. The cuboid is quite elongate 

 and with a narrow anterior face ; it has a large posterior tuberosity not 

 projecting much posteriorly. The navicular is flat with a sigmoid prox- 

 imal face, convex on the inner side, concave on the outer. It has the 

 three cuneiform facets below, the inner antero-posterior. The inner is a 

 flat bone with antero-posterior plane, and apex directed backwards, and 

 considerable oblique facet for the second metatarsal. The mesocuneiform 

 is much the smaller and brings the third metatarsus a short distance 

 proximal to the fourth. The ectocuneiform is a little wider than deep. 

 The metatarsals are three, and are rather slender. The two outer are 

 equal in length, and the median but little wider proximally, the increased 

 width being more obvious distally. They have no proximal grooves, and 

 the outer has a low outer tuberosity. The facets of the second row of 

 tarsals are [ \ \. The phalanges, including ungueal, are 3, 3, 3. The 

 proximal ones are longer than wide and contracted at the ends ; the
