This facet is situated immediately in front of the deep pit which characterises the posterior part of this surface of the fibula. A small lunated facet is frequently found upon the anterior surface of the distal end of the tibia, particularly among those races characterised by the adoption of the "squatting ' posture. When this facet exists it is continuous with the anterior margin of the roof of the socket, and it articulates with a similar facet upon the superior surface of the neck of the talus m the extreme flexion of the ankle-joint which "squatting" entails. The articular surface upon the body of the talus adapts itself to the tibio- fibular socket, and presents articular facets corresponding to the roof and sides of the socket. Thus the superior surface of the talus possesses a quadrilateral articular area, wider in front than behind, distinctly convex in the antero-posterior direction, and slightly concave transversely. In addition, towards its postero- lateral margin, there is also a narrow antero-posterior facet corresponding to the distal ligament of the lateral malleolus. The articular cartilage of this superior surface is continued without interruption to the tibial and fibular sides of the bone, although the margins of the superior area are sharply defined from the facets on the sides, the lateral of which Anterior ligament of lateral malleolus ^ triangular in Outline, while the medial is piriform, but in each case the surface is vertical.
