The femur is long and has three trochanters, the third 

 trochanter being on the outer side. The tibia is also long 

 and is fused with the fibula, though the proximal end of the 

 latter is separate for part of its course. 



The tarsus consists of a condylar astragalus articulating

 and the cuboid are distinct. 



The first metatarsal and digit are absent, but the other 

 four are long, and each bears a three-jointed digit.
