the proximal edge (and continued in some specimens for a short dis- 

 tance down the plantar border), and an adjoining but more distal con- 

 cavity. The articular strip is concave in both directions, and some- 

 times a groove for a slip from the tendon of the peroneus longus

muscle divides it into dorsal and plantar halves. It joins the articular 

 facets on the tibial side of the base of the fifth metatarsal ; one of these 

 facets also fits into the anterior half of the adjoining concavity, whereof 

 the posterior half is rough and affords attachment to a ligament. 



The tibial surface (Fig. 600) is rough and irregular. On the 

 dorsal border, at some distance from the proximal rim, is a projection, 

 bearing a smooth oval surface, which faces to the proximal, tibial, and

dorsal sides and fits into the deep excavation on the fibular side of the 

 base of the third metatarsal. Proximal to this projection is a shallow 

 area which is adjusted to a swelling on the third metatarsal. The 

 entire surface is divided into two by a median groove. On the promi- 

 nent plantar border, and encroaching also somewhat on the plantar 

 surface, is an oval, slightly concave facet. It faces to the plantar and 

 the tibial side, and articulates with the plantar concavity on the fibular 

 surface of the third metatarsal.
