Speed Comparison of Land Animals

Now a days I often watch television and specially look for animal channels like Discovery, Animal Planet and National Geography. While I see a tiger/cheetah/lion attacks a deer I always wonder what is the highest speed of various types of land animals. After searching a bit in Internet and also from animal channels I have got ideas about the animals speed which I specify below along with their name. All the measurements of speed are given as mile per hour (mph).

1)Peregrine falcon: 200.00+
